* feat(web,core): import client configs and registry server.json (#1348)
Wire up the two server-import affordances that were previously todoNoop:
- Import config: source picker (Claude Desktop / Cursor / Cline / VS Code)
read on the backend via a new GET /api/import-source, plus a file-upload
fallback. Per-server review with import/skip on new servers and
overwrite/skip/rename on id conflicts, then a per-server outcome summary.
- Import server.json: parse the MCP registry single-server format
(npm/pypi/oci packages + remotes, env vars, package/runtime args, URL
template vars) into a runnable config, with a file picker and debounced
live validation; Add Server is disabled until validation passes.
Core gains an isomorphic import strategy layer (core/mcp/import) with a
strategy registry, client-config + server.json parsers, a strategy-agnostic
merge, and a dependency-injected source resolver. useServers exposes
importSource(). Modal headers are bold and the redundant server.json section
header is folded into the modal title.

* feat(web): collapse the server.json textarea into a File Contents disclosure

* feat(web): auto-collapse File Contents disclosure after content loads
Once content is pasted or a file is loaded, collapse the File Contents
disclosure after ~1s with Mantine's built-in accordion animation, signaling
the input was accepted and surfacing the validation/env-var sections. The
disclosure becomes controlled by the modal; clearing the textarea re-opens it.

* feat(web): flash File Contents hover highlight before auto-collapse
Before the File Contents disclosure auto-collapses, paint it with its hover
background for 250ms, then run the collapse over a 325ms animation, so the
collapse reads as intentional.

* refactor(web,core): move import orchestration into core helpers + web hooks
Make the import logic reusable by CLI/TUI and keep the modals display-only:
- core/mcp/import: add parseClientConfig (mcpServers→servers fallback),
resolveServerId, selectServerJsonOption, and buildServerConfigForSelection,
so the full import (parse → select → build → merge) is callable from any
environment.
- core/storage: extract the pure validateStoreId into a Node-free store-id
module (store-io re-exports it) so the isomorphic import layer can validate
ids without pulling Node deps into the browser bundle.
- clients/web/hooks: useServerJsonImport and useImportClientConfig own all the
wizard/parse/debounce/apply state; ServerImportConfigModal and
ServerImportJsonModal are now thin display shells over the dumb panel.

Name override field stay hidden until something has been pasted/loaded into the
textarea.

editable Override field.

* feat(web): scroll to and highlight a freshly-added server
After a manual add/clone or an import (client config / registry), the new
server's card scrolls into view and draws an animated border (Mantine Border
Animate); clicking anywhere on the card dismisses it.
- App tracks highlightedServerId; addServerHighlighted sets it (edits and
conflict-overwrites don't). Threaded through InspectorView -> ServerListScreen
-> ServerCard.
- ServerCard scrolls into view on highlight and wraps in <BorderAnimate>;
onClick clears the highlight.
- Pin @gfazioli/mantine-border-animate@2.0.3 (Mantine 8 compatible; 2.0.4+
requires Mantine 9).
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* fix(web): highlighted card fills its cell and its controls work on first click
- The BorderAnimate wrapper is display:flex, so the card was shrinking to
content width while the border spanned the cell. Stretch the card with
w=100% (and the wrapper).
- Always render BorderAnimate and toggle show/animate instead of conditionally
wrapping: swapping the element type on clear remounted the card, swallowing
the click that triggered it (e.g. the connect toggle fired clear but not
connect, needing a second click). Verified: one click now connects + clears.

* fix(web,core): address review — OCI env, untrack fixture, rename validation
- Untrack the stray inspector-v1-multi.server.json (accidentally committed) and
gitignore root *.server.json fixtures.
- core/mcp/import/serverJson: forward declared env vars into OCI containers via
'-e KEY' docker args (they previously only set the docker CLI process env);
add a test. Clarify buildServerConfig (destructure env out instead of
spread-then-delete) and document value-vs-default env handling.
- useImportClientConfig: validate 'rename' targets inline (invalid charset /
collision with existing, additions, or other renames) and gate the Import
button on canImport; surface the error on the field.

* feat(web): highlight all servers from a batch import, not just the last
Track highlighted servers as a set of ids instead of one. addServerHighlighted
accumulates each id (a multi-server client-config import highlights them all);
opening an add/import modal starts a fresh batch. Clicking a card clears only
that card's highlight; only the first highlighted card scrolls into view.

* refactor(launcher): self-contained validate; split smokes into top-level step (#1504)
Previously `validate:launcher` built cli/tui/web and ran the cross-client
smokes, so the launcher's "validation" depended on every other client
being built — and the launcher had no lint/format/coverage of its own.
- clients/launcher: add a web-style `validate` (format:check && lint &&
build && test:coverage) with a Node-only eslint flat config, prettier,
and a per-file coverage gate (parse-launcher-argv.ts covered;
src/index.ts excluded as binary bootstrap). 100% on the gated file.
- Root `validate:launcher` now just delegates: `cd clients/launcher &&
npm run validate` — no dependency on the other clients.
- New top-level `smoke` step (smoke:launcher + smoke:cli + smoke:tui +
smoke:web) with NO build commands; `validate` runs it last. Each
client's own validation builds its bundle first, so nothing builds
twice (cli/tui via test:coverage, launcher via its validate;
smoke:web builds dist on demand).
- clients/tui test:coverage now builds the TUI bundle (mirroring cli) so
the build-free smoke has it available.
- CI: replace the standalone cli/tui/launcher build step with a
"Validate launcher" step. Docs updated (AGENTS.md, launcher README).
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* refactor(cli,tui,root): every client self-validates; smoke separate from validate
Extends the launcher self-validate work to the CLI and TUI, and makes the
top-level `validate` nothing but the per-client validations — smokes are
now a separate top-level target.
- clients/cli, clients/tui: add a web-style `validate` with a Node flat
eslint config + prettier. CLI lint/format pass as-is. TUI registers
eslint-plugin-react-hooks for the classic rules only (rules-of-hooks +
exhaustive-deps, which the source already references); the stricter
react-hooks@7 rules are not enforced on the interim component surface
(#1501).
- Avoid double builds:
- CLI's e2e spawns the built binary, so its `test:coverage` builds first;
`validate` folds that in (`format:check && lint && test:coverage`, no
separate `build`).
- TUI tests don't spawn a bundle, so `validate` keeps an explicit
`build` (for the smoke) and `test:coverage` is pure.
- Root: `validate` = validate:web && validate:cli && validate:tui &&
validate:launcher (each delegates to the client's own validate). `smoke`
is no longer part of `validate` — it's a separate top-level target run
after a build/validate, with no build commands of its own.
- CI: per-client "Validate X" steps + a single "Run cross-client smokes"
(npm run smoke). Docs updated (AGENTS.md, cli/tui READMEs).
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* chore(root): drop redundant test aggregator scripts
Now that every client self-validates and the top-level `validate` chains
the per-client validations, the root `test` / `test:web` / `test:cli` /
`test:tui` / `test:coverage` aggregators are redundant — run
`npm run validate` (all) or `cd clients/<name> && npm run validate` (one).
`test:storybook` stays (it's the one check not part of validate). CI was
already using each client's own scripts, so it's unaffected. Docs updated.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* test(web): silence happy-dom infra noise in unit runs
Passing unit runs printed dozens of alarming-but-expected lines that made
green runs look broken — all from happy-dom performing real I/O with no
server behind it:
- `<iframe src="/sandbox.html">` (MCP Apps sandbox) made happy-dom fetch
and later unload that URL, emitting ~40 `DOMException [NetworkError/
AbortError]` + `AsyncTaskManager destroyed` lines. Disable child-frame
navigation in the unit project (the tests only assert on the iframe
element/attributes, not its document), removing the noise with no
coverage loss.
- App-level renders read `GET /api/config` via useSandboxUrl /
useServerListWritable, 404-ing ~76x. Add a benign default `fetch` (empty
200) in the unit setup; tests that exercise fetch still override it.
Negative tests that assert on errors already suppress their own console
output (e.g. jsonUtils/schemaUtils); CLI, TUI, and the web integration
suite were already clean. Unit suite is now noise-free; 2424 web tests
pass and the coverage gate is unchanged.

* refactor(scripts): make validate fast (test), split coverage into its own target
Each client's `validate` now runs `test` instead of `test:coverage`, so
the everyday pre-push check skips v8 instrumentation (and, for web, the
slower integration project). The per-file coverage gate moves to a
dedicated top-level `coverage` script:
coverage = coverage:web && coverage:cli && coverage:tui && coverage:launcher
coverage:<name> = cd clients/<name> && npm run test:coverage
`validate` still builds each client's bundle (cli via its test `pretest`,
the others via an explicit `build`), so `npm run validate && npm run
smoke` works unchanged. CI now runs `validate` (fast checks + builds),
then `coverage` (the gate), then `smoke` — collapsing the old per-client
steps. Docs updated.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* ci: drop the coverage gate from CI; keep web integration as its own step
CI no longer runs `npm run coverage` — the per-file coverage gate is now a
local/manual check (`npm run coverage` before pushing). To avoid silently
dropping the web integration suite (it only ran via test:coverage, and
`validate` runs the unit project only), CI gains a standalone
`clients/web` `test:integration` step that exercises the real
stdio/HTTP/OAuth/storage paths without coverage instrumentation.
CI is now: validate (fast) → web integration → smoke → storybook. Docs
updated.

* refactor(smoke): give smoke:launcher its own script like the others
smoke:launcher was the odd one out — an inline chain of three
`node clients/launcher/build/index.js ... --help` commands while smoke:cli
/ smoke:tui / smoke:web each run a `scripts/smoke-*.mjs`. Extract it to
`scripts/smoke-launcher.mjs`, which runs the same `--help` / `--cli --help`
/ `--tui --help` dispatch checks but now also asserts each prints that
mode's usage banner (proving the launcher resolved the right client build)
and verifies the required builds exist up front with a clear error. Prints
a `smoke:launcher OK — ...` summary in the same style as the rest. Docs
updated.

* chore: reorder package.json scripts for readability
Move frequently-run scripts toward the top and rarely-run-by-hand ones
(pretest hooks, lint/format internals, etc.) toward the end, consistently
across the root and client manifests. Pure reordering — no script names or
values changed, and no other manifest content is touched.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* docs: drop references to removed root inspector / test:storybook scripts
The reordering dropped the root `inspector` and `test:storybook`
aggregators (intentional — `inspector` is redundant with `web`, and
storybook is run from clients/web in CI). Update AGENTS.md so it no longer
points at `npm run inspector`, and run `test:storybook` from `clients/web/`.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* chore: address PR #1505 review (format glob gap, fetch-baseline comment)
- TUI format/format:check now also cover the client-root source files
(index.ts, tui.tsx, dev.ts) that live outside src/ — `eslint .` already
lints them, so they were linted but not format-checked. (cli/launcher
have no source outside src/; their root .ts are single-quoted configs
intentionally left out of prettier, matching web.)
- Reword the setup.ts default-fetch comment: it overstated auto-restore
(the unit project sets no restoreMocks/unstubGlobals), and now also
flags that the permissive 200 default means a test asserting on a fetch
FAILURE must install its own rejecting stub.

* chore: remove redundant root install:clients script
`install:clients` ran the same `node scripts/install-clients.mjs` as
`postinstall`, which fires automatically on `npm install` — so the manual
alias was redundant. Drop it and the doc references (AGENTS.md, spec).
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* fix(ci): skip smoke:tui in CI (Ink needs a real TTY)
This PR made CI run the full `npm run smoke`, which surfaced that
smoke:tui fails in headless CI: the Ink TUI throws "Raw mode is not
supported" on mount (no TTY) and exits before rendering its first frame.
The old CI never ran smoke:tui, so this was latent.
smoke-tui.mjs now self-skips when `process.env.CI` is set — the boot/
render check is inherently local-only (a TUI needs a terminal). The TUI is
still built and unit-tested in CI; `npm run smoke` stays the single
command everywhere (full locally, tui-skipped in CI). Verified
`CI=true npm run smoke` is green (launcher/cli OK, tui SKIPPED, web OK).
Docs + CI comment updated.

* test(cli,tui): add in-process source coverage gates (#1484)
CLI and TUI source had no coverage gate: CLI tests spawned the built
binary out-of-process (coverage never saw clients/cli/src) and the TUI
had only two smoke tests. Regressions there were invisible to CI.
CLI:
- Rewrite __tests__/helpers/cli-runner.ts to invoke runCli() in-process
(capture process.std*.write, map thrown errors to an exit code),
preserving the CliResult shape so all existing tests run unchanged and
clients/cli/src is now measured under v8 instrumentation.
- cli.ts: program.exitOverride() so a commander usage error throws
(catchable in-process) instead of tearing down the worker; --help /
--version still exit cleanly. Drop the dead, never-imported main().
- Add a thin out-of-process e2e.test.ts that spawns the built binary for
the shebang / process.exit paths the in-process runner can't reach.
- Add @vitest/coverage-v8, a per-file gate (90/85/80/50) excluding only
src/index.ts (binary bootstrap), and pool: 'forks' for capture
isolation. cli.ts lands at ~98% lines / 100% functions.
TUI:
- Add @vitest/coverage-v8 and an interim per-file gate over the
non-React logic (logger.ts, components/tabsConfig.ts, utils/*); the
Ink components, App.tsx, and hooks/ are excluded with a documented
follow-up (#1501). Add tests covering the included modules (100%).
Wiring + docs:
- CI runs each client's test:coverage; root test:cli / test:tui (used by
validate) and root test:coverage now enforce the gates.
- gitignore clients/**/coverage; update AGENTS.md and client READMEs.

* docs(cli): clarify in-process runner footguns from PR #1502 review
Review notes on the in-process CLI test runner (no behavior change):
- Warn in runCli's docblock that --help/--version must NOT go through the
in-process runner: exitOverride only re-throws non-zero exits, so exitCode
0 falls through to process.exit(0) and would kill the vitest worker. Those
belong in the out-of-process e2e.test.ts layer.
- Document that a timeout orphans the uncancellable invokeCli promise (its
stdio subprocess stays alive; later writes hit the restored stdout) — a
known, acceptable trade-off on the hang-only failure path.
- Fix a stale reference to the removed main() (errors now route through
index.ts).

* docs(cli): fix remaining stale main() reference in vitest exclusion comment
PR #1502 re-review caught a second stale `main()` mention (the first was
fixed in 52c23e41). src/index.ts inlines the bootstrap as
runCli(process.argv).then(...).catch(handleError) — there is no main().
Comment-only; no behavior change.

* chore: compose root test:coverage from per-client scripts
Replace the brittle inline cd-chain with a composition of the existing

truth for each client's coverage invocation.

* feat(cli,tui): normalize --catalog / --config with web; update --help (#1347)
Bring the CLI and TUI in line with the web catalog vs read-only session
model introduced in #1481/#1483, and close the outstanding --help item
from #1347.
Core (core/mcp/node/config.ts):
- Add `catalogPath` to ServerConfigOptions (writable catalog slot).
- `resolveServerSource()` picks the active source: `--catalog` (writable,
seed-if-missing) wins over `--config` (read-only, error-if-missing).
- Writable sources seed an empty `{"mcpServers":{}}` on first run (matches
the web backend) instead of erroring; read-only `--config` still errors.
- `serverSourceConflict()` shared conflict matrix (mirrors run-web):
--catalog/--config mutually exclusive; neither combines with an ad-hoc
target.
- `readServerListFile()` public loader for runners (TUI) needing the raw map.
- Rename `withDefaultConfigPath` → `withDefaultCatalogPath`; the no-flag
default now fills the writable catalog slot, not --config.
CLI / TUI:
- Add `--catalog <path>` (+ MCP_CATALOG_PATH) and re-document `--config` as a
read-only session in --help.
- Enforce the shared conflict matrix before resolution.
Full writable persistence/CRUD threading remains deferred to #1482 / #1432
(CLI/TUI are read consumers today; the split surfaces as seed- vs
error-on-missing).
Tests: core resolution matrix (source/conflict/seed/read-only), CLI catalog
+ conflict integration tests, TUI loadTuiServers unit tests. READMEs updated.

* test(launcher): add smoke:cli + smoke:tui e2e launcher smokes (#1347)
The launcher smokes only checked `--help` for --cli/--tui; nothing
exercised the launcher → CLI/TUI → core path on the built artifact (only
smoke:web did, for web). Add two end-to-end smokes wired into
validate:launcher between smoke:launcher and smoke:web:
- smoke:cli (scripts/smoke-cli.mjs): runs `--cli` against the bundled
stdio test server via a temp --catalog and asserts tools/list returns
the tools, plus the #1347 resolution paths — default-catalog
seed-on-missing, read-only --config error-without-seed, and the
--catalog/--config conflict.
- smoke:tui (scripts/smoke-tui.mjs): launches `--tui --catalog <temp>`
and asserts the Ink app renders its first frame ("MCP Servers") within
a timeout, then SIGTERMs it (shallow boot/render check).
Both build test-servers/build on demand if missing. Docs updated
(AGENTS.md validate description, launcher README).

* refactor: address review on #1499 (comment accuracy, CLI/TUI flag parity)
Review feedback from @claude on PR #1499 (all non-blocking):
- Align CLI catalogPath resolution with the TUI: `options.catalog?.trim()
|| process.env.MCP_CATALOG_PATH` so an explicit empty `--catalog ""`
falls back to MCP_CATALOG_PATH identically in both front-ends (CLI used
`??`, which only guards undefined/null).
- Clarify the `serverSourceConflict` comment: it mirrors only the
source-selection portion of web's matrix and deliberately omits web's
`--header` rejection, since CLI/TUI merge --header into per-server
settings.
- Note the deliberate --header broadcast semantics in loadTuiServers.
- Share an EMPTY_CATALOG_CONTENT constant between seedEmptyCatalog and
readServerListContent instead of two separate literals.

* feat(web): build dist on demand for prod --web + end-to-end CI smoke (#1486)
Prod `mcp-inspector --web` serves static assets from clients/web/dist,
which only exists after a build. In a fresh checkout it was absent and the
prod path served a broken page (ENOENT on index.html); the launcher smoke
test only covered --help, so this path was unverified in CI.
- ensure-web-build.ts: build dist on demand (vite build via build:client)
when missing, or exit with an actionable error if the build can't run.
- run-web.ts: invoke ensureWebBuild before startHonoServer in the prod path
(--dev runs Vite directly and skips it).
- scripts/smoke-web.mjs + smoke:web: start --web against built dist and
assert GET / returns 200 with the injected __INSPECTOR_API_TOKEN__.
Wired into validate:launcher and a new CI step.
- Docs: launcher README + AGENTS.md.

* fix(web): surface spawn error in build-on-demand; clarify smoke comment
Address PR #1497 review:
- runViteBuild now logs result.error.message (e.g. ENOENT when npm isn't on
PATH) before returning a null status, so the spawn-failure cause surfaces
instead of only the generic actionable error. The build seam gains a `log`
param; added a test covering the ENOENT path.
- Reword scripts/smoke-web.mjs header so it no longer implies the readiness
wait covers a cold build-on-demand vite build (it's sized for a pre-built
dist, which validate/CI guarantee).

Root `npm run validate` previously delegated only to `clients/web`
(`format:check` + `lint` + `build` + `test:coverage`), so a contributor
running it before pushing could miss CLI/TUI/launcher breakage that CI
would later catch. There was no single local command mirroring CI.
Extend root `validate` to mirror the CI job end to end:
- `validate:web` — web format:check + lint + build + test:coverage
- `test:cli` / `test:tui` — CLI and TUI suites
- `validate:launcher` — build CLI + TUI + launcher, then the launcher
`--help` smoke (`smoke:launcher`: --help, --cli --help, --tui --help)
The new sub-scripts can be run individually when iterating on one
client. Storybook stays out of `validate` (Playwright-dependent, slow),
consistent with the existing convention. Documented in AGENTS.md.

The `UNRESOLVED_IMPORT` warnings that `quiet-config-warnings.mjs` suppressed
no longer occur, so the filter (and the build-time `onwarn` suppressions for
the same three deps) are removed.
Root cause: Vite's config bundler (Rolldown) statically walks the node-only
dev backend (`core/mcp/remote/node/server.ts`) when it loads `vite.config.ts`,
reaching `chokidar`, `atomically`, and `@napi-rs/keyring`. `core/` has no
node_modules of its own, so at config-bundle time those deps resolve from
`core/`'s parent chain — the repo-root `node_modules`. Before #1452 the deps
lived only under `clients/web/node_modules` (a sibling, off the resolution
chain), so Rolldown emitted `UNRESOLVED_IMPORT`. #1452 declared them in the
repo-root `package.json` (for the CLI/TUI/launcher, which consume core/'s node
code), installing them at the repo root and making them resolvable. Verified
by hiding the root copy: the warning returns; restore it and the dev/build
startup is clean.
A dynamic import of the backend does not help — Rolldown follows dynamic
imports during config bundling too. The fix is the deps being resolvable, so
the suppression is just removed and the invariant is documented in
`vite.config.ts`.
- Remove `clients/web/server/quiet-config-warnings.mjs` + `.d.mts` and its test
- Restore the `dev` script to plain `vite` (drop the `--import` hook)
- Remove the now-dead `build.rollupOptions.onwarn` UNRESOLVED suppressions
(never fire: the Hono plugin is `apply: 'serve'`, out of the build graph)
- Document why config-bundle resolution succeeds in `vite.config.ts`
- Update AGENTS.md project tree

double-start), the root `postinstall` install cascade with simplified CI, and
spec/AGENTS docs (no-workspaces rationale, Development setup).
Closes#1246.

* chore(web): silence benign config-load dep warnings in `npm run dev`
`vite dev` printed three UNRESOLVED_IMPORT warnings at startup (chokidar,
atomically, @napi-rs/keyring). They originate from Vite's config bundler
(Rolldown): the Hono plugin statically imports the node-only dev backend
(core/mcp/remote/node/server.ts), so loading vite.config.ts bundles it and
Rolldown walks its node-only deps. Those deps are correctly externalized — the
browser never loads them and Node resolves them at runtime — so the warnings are
pure noise.
They can't be filtered the usual ways: the static import is required (the
monorepo has no node_modules under core/, so the aliases must resolve the deps
at bundle time — ssrLoadModule / `--configLoader runner` both fail to resolve
them), and the warnings are written directly to the process streams during
config load, bypassing customLogger, logLevel, and rollupOptions.onwarn.
Fix: a tiny `--import` hook (server/quiet-config-warnings.mjs) that drops only
those specific benign warning writes, wired into the `dev` script. Scoped to
`npm run dev` — build, tests, and prod are untouched.

* chore(web): harden dev warning filter per review
- Tighten BENIGN_PAIRS to repo-relative path fragments (not basenames) so an
unrelated future UNRESOLVED_IMPORT warning mentioning the same dep + a
same-named file isn't silently dropped. Verified Rolldown prints the full
repo-relative path. (review #1)
- Add a note that the matcher tracks Rolldown's message format and degrades to a
safe no-op (warnings return) if that format changes. (review #2)
- Export isBenignWarning/BENIGN_PAIRS, guard the stream patching behind
!VITEST, add a .d.mts so the pure helper is importable from TS, and add a unit
test locking the signature pairs and the over-match guards. (review #3)

* feat(auth): inject MCP_INSPECTOR_API_TOKEN into served index.html (#1378)
Reloading the web client at the bare URL (no `?MCP_INSPECTOR_API_TOKEN=…`
query string) with empty sessionStorage made every `/api/*` request 401 —
the browser had no way to recover the backend's auth token.
Embed the token into `index.html` on every page load so the browser no
longer depends on the query string surviving navigation:
- New shared helper `clients/web/server/inject-auth-token.ts` embeds
`<script>window.__INSPECTOR_API_TOKEN__ = "…"</script>` (escaped against
`</script>` injection; no-op when auth is dangerously omitted).
- Dev: the Vite plugin injects via `transformIndexHtml`.
- Prod: the Hono server injects on the `/` route.
- `App.tsx` `getAuthToken()` now reads the injected global first, then the
query string, then sessionStorage (both fallbacks preserved).
- Shared global name lives in `INSPECTOR_API_TOKEN_GLOBAL`
(`core/mcp/remote/constants.ts`).
Tests: helper unit coverage + an integration test exercising the real
prod server's `/` → `/api/*` flow (injected token authenticates; missing
token 401s). AGENTS.md documents the token-recovery order.

* fix(auth): inject token into prod SPA fallback + prime sessionStorage + no-store (#1378)
Addresses code-review feedback on the token-injection PR:
- Prod `server.ts` SPA deep-link fallback (e.g. `/oauth/callback`) previously
served the raw index.html off disk via serveStatic, bypassing injection — so
a bookmark/reload at a non-`/` route with empty sessionStorage would 401.
Route the SPA fallback through the same `serveIndexHtml` (inject) helper;
real static assets (paths with a dot) still serve verbatim. Dev already
injected on every HTML serve via Vite `transformIndexHtml`.
- `getAuthToken()` now persists the injected `window.__INSPECTOR_API_TOKEN__`
to sessionStorage (not just the URL-param branch), priming the backstop for
any later navigation that loses the global.
- Injected HTML responses now send `Cache-Control: no-store`, so a page
carrying a token isn't cached and served stale after a restart regenerates
the token.
Integration tests added: SPA fallback (`/oauth/callback`) carries the token,
`Cache-Control: no-store` on injected HTML, real assets served verbatim, and
unknown `/api` routes 404 rather than falling through to the HTML shell.

* feat(server-info): wire Server Info modal to the connection handshake
Closes#1364
- Add ServerInfoModal wrapping the existing ServerInfoContent, mirroring the
ServerSettingsModal layout.
- Gate the Server Info button on ServerCard to render only when the
connection is "connected".
- Expose `getClientCapabilities()` on InspectorClient (and protocol +
FakeInspectorClient), and surface it through useInspectorClient so the
modal can render the client side of the capability handshake without
poking the SDK Client's private state.
- App.tsx: open the modal from the gated Server Info button, derive the
active server's transport and OAuth details (synchronously, from the
guided-OAuth state snapshot + persisted settings), and reset the open
flag on InspectorClient `disconnect` so the modal does not auto-reopen
on a future reconnect.

* fix(server-info): dedupe modal header and render instructions in ContentViewer
- Drop the in-content "Server Information" Title from ServerInfoContent and
rename the modal title to "Server Information" so the modal renders one
heading instead of two stacked ones.
- Swap the instructions Blockquote for ContentViewer (copyable, with the
existing wrapping Code variant) so long instructions wrap and the user
can copy the full payload.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* refactor(server-info): rename ServerInfo -> ConnectionInfo
The popup covers server identity AND client capabilities AND OAuth state —
it's a snapshot of the live connection, not just the server. Rename to match
what it actually shows. Also add a "Server Implementation" heading above
the top section (name/version/protocol/transport) to balance the existing
capability headings.
- ServerInfoContent -> ConnectionInfoContent (directory, file, exports)
- ServerInfoModal -> ConnectionInfoModal (directory, file, exports)
- ServerCard button label "Server Info" -> "Connection Info";
prop onServerInfo -> onConnectionInfo
- Modal title -> "Connection Info"
- App.tsx / ServerListScreen / InspectorView wiring updated to match
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* fix(connection-info): cap instructions block height so it scrolls in place
A long server prompt (e.g. an Everything-style instruction document) was
pushing the OAuth section and the modal chrome off-screen — users had to
scroll the whole modal to reach the close button. Wrap the ContentViewer
in ScrollArea.Autosize with mah=280 so the instructions section scrolls
internally and the rest of the modal stays put.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* feat(connection-info): add subtle background to section headings
Add a `section` variant for Title that paints the heading in the existing
`--inspector-surface-subtle` token (same surface token already used for
modal call-out panels). Apply it to each section heading in
ConnectionInfoContent (Server Implementation, Server Capabilities, Client
Capabilities, Server Instructions, OAuth Details) via a SectionHeading
subcomponent constant, so the sections read as distinct cards against the
modal background instead of bleeding into one stream of text.

* fix(stories): wrap long import line in ConnectionInfoModal.stories.tsx
Prettier flagged the import in CI. The line exceeded printWidth=80 and
needed to wrap onto multiple lines.

* docs(agents): require `npm run format` before committing
Add a pre-commit instruction to run the auto-fixing `npm run format` ahead

will fail CI on any unformatted file — running the auto-fixer first
eliminates that class of failure entirely.

* chore(favicon): use theme/assets/MCP.svg as the favicon source of truth
Point index.html's icon link at /src/theme/assets/MCP.svg so the same MCP

now-unused clients/web/public/favicon.svg. Vite resolves the source path
during build and emits a hashed copy under dist/assets/.

* fix(server-card): surface failed-handshake errors with a 5s auto-dismiss
Two related fixes so the user actually sees what went wrong when a
connect attempt fails (e.g. OAuth-backed server, bad URL, missing dev
auth token):
- App.tsx: add `connectInFlightRef` and skip clearing `activeServerId`
in the InspectorClient `disconnect` listener while a connect attempt
is in flight. The transport closes during a failing handshake and
dispatches `disconnect` before the catch block sets `errorMessage`;
without this guard InspectorView would map the card to plain
"disconnected" and the InlineError would never render.
- InlineError: opt-in `autoDismissMs` prop that runs a Mantine `slide-up`
Transition exit animation after the message has been visible for the
given duration. Visibility is derived from a "dismissed message"
state (rather than a mounted boolean + setMounted-in-effect), so the
timer re-arms whenever `error.message` changes without tripping the
react-hooks/set-state-in-effect rule. ServerCard passes
autoDismissMs={5000}.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* refactor(server-card): own InlineError visibility + animate parent-driven removal
Move the 5s auto-dismiss timer and visibility state out of InlineError
and into ServerCard so the slide-up exit animation runs in both cases:
- Timer-driven: after 5s the alert animates out (existing behavior).
- Parent-driven: when `connection.error` is cleared mid-flight (e.g. a
successful reconnect), the alert ALSO slides up instead of vanishing.
To keep the message painted during the parent-driven exit, ServerCard
tracks a `lastError` state that mirrors `connection.error` only on its
truthy edges. The conditional setState during render is the supported
React pattern for "remember the last seen value of a prop"; gated on
message inequality so it can't loop. The `useRef` version of this
pattern failed `react-hooks/refs` (no ref writes/reads during render).
InlineError is now a pure presentational component: `mounted` prop
controls a Mantine `slide-up` Transition. The internal `autoDismissMs`
prop is gone — its single caller has moved to the controlled `mounted`
pattern.
Closes the "error vanishes the moment the parent removes it" half of #1364
(the timer half landed in 6d147e0f).

* refactor(server-card): surface connection errors as a toast, drop InlineError
Move handshake-failure messaging out of the ServerCard body and onto a
Mantine toast (`notifications.show`). The inline alert had a 5-second
visibility contract entangled with InspectorView's status pipeline, and
the active card was flipping through error → disconnected → error during
a failing handshake; surfacing the error as a toast sidesteps that whole
timing problem and keeps the card focused on the live status indicator.
- App.tsx: toast on the connect-catch path; drop `errorMessage` state +
`connectInFlightRef` (the latter was only there to keep the inline
alert visible past the transport's close event).
- InspectorView: drop the `errorMessage` prop and the
`connectionStatus === "error" && errorMessage` mapping branch.
- ServerCard: drop the InlineError rendering + the displayedError /
errorVisible visibility state machine.
- Delete the InlineError component — no other consumers.

* chore(notifications): anchor toasts to the bottom right
Move the Notifications portal from top-right to bottom-right so a
connection-failure toast doesn't overlap the ViewHeader / tabs row.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* review: address PR feedback on the Connection Info modal
1. Hoist `EMPTY_CLIENT_CAPABILITIES = Object.freeze({})` to module scope
in `useInspectorClient` so the fallback returns a stable reference
(avoids invalidating downstream `useMemo`/`useEffect` deps when no
client is attached).
4. Drop the `?? "stdio"` silent fallback on `connectionInfoTransport`
in the JSX — gate the modal render on `activeServer` too. The
"stdio" default still lives at the derivation site (config.type is
schema-optional and `ServerType` is required by the modal prop),
but the gate makes the invariant explicit.
6. Replace the raw `document.querySelector("button.mantine-CloseButton-root")`
in `ConnectionInfoModal.test.tsx` with `screen.getByRole("button",
{ name: /close/i })`. Add `aria-label="Close"` to the
CloseButton so the assertion (and screen readers) have a name to
match on.
7. Switch the OAuth scope splitter from `/\s+/` to the literal `" "`
per OAuth 2.1 §3.3.
Also clarify in comments:
2. Note that `connectionInfoOAuth` uses snapshot-at-open semantics on
purpose — token refreshes mid-session won't re-render the modal.
5. Note that we prefer the AS-advertised `authorization_endpoint`
over `authorizationUrl` because the latter is per-flight noise
(state, code_challenge) rather than a stable identifier.
Finding 3 (modal exit animation short-circuited by the `{initializeResult
&& …}` guard) left as intentional — we want the snap-shut on disconnect
so a stale info dialog can't keep rendering with no live client behind it.

* docs(connection-info): tighten the OAuth memo comment per re-review
The reviewer noted that "snapshot-at-open" was imprecise — the memo
re-runs on any of its deps (connectionStatus, inspectorClient,
activeServer), which includes settings edits that re-reference the
active server. Reframe as "snapshot-at-last-derivation" and call out
the natural triggers (server switch, reconnect, settings edit) so a
future reader doesn't conclude the memo is open-only.

* feat(web): port v1.5 dev backend (vite-hono-plugin + sandbox + remote-server bootstrap)
Ports the v1.5 in-process dev backend into v2 so `npm run dev` serves the
Hono remote-server (`/api/*`) alongside the Vite-served browser app. Without
this, the browser-side `createRemoteTransport` had nothing to talk to during
local development.
Adds under `clients/web/server/`:
- vite-hono-plugin.ts (Hono middleware on the Vite dev server; gated to
`apply: 'serve'` and skipped when `process.env.VITEST` is set so it stays
inert in vitest/storybook runs)
- sandbox-controller.ts (standalone HTTP server for the MCP Apps sandbox)
- web-server-config.ts (env parsing + initial-config payload + banner;
`autoOpen` defaults off under VITEST so test runs don't shell out to `open`)
- server.ts (standalone Hono prod server for the future v2 launcher, #1246)
- start-vite-dev-server.ts (in-process Vite starter for the future launcher)
- vite-base-config.ts (shared optimizeDeps exclusions)
Wires `honoMiddlewarePlugin(buildWebServerConfigFromEnv())` into
`vite.config.ts` with `apply: 'serve'`. Adds the `open` dependency and a
DOM lib + `@inspector/core/*` path alias to `tsconfig.node.json` so the
dev-backend files type-check alongside vite.config.ts.
Coverage: web-server-config.ts (100% lines), sandbox-controller.ts (91% lines),
and vite-base-config.ts (100%) all clear the per-file gate. The Vite plugin,
prod server, and dev-server starter are excluded from coverage as runtime
glue exercised by `npm run dev` end-to-end (callers covered separately;
their logic lives in core/mcp/remote/node, which integration tests already
exercise).
Closes#1320.
Unblocks #1244 (Wire App.tsx) — its test plan can now run end-to-end.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* fix(web/server): address PR review feedback on the dev-backend port
- sandbox-controller: resolve start() with empty values on listen error
(e.g. EADDRINUSE on a fixed MCP_SANDBOX_PORT) instead of leaving the
promise pending forever. Without this, the Vite plugin's
`await sandboxController.start()` could hang the entire dev backend on a
port collision. Banner now silently omits the sandbox line; getUrl()
keeps returning null. Adds a regression test exercising the EADDRINUSE
path against a real socket.
- vite-hono-plugin: listen for `error` and `close` on the incoming request
stream (in addition to `end`) so an aborted POST/PUT (browser navigates
mid-upload) doesn't leak the middleware indefinitely.
- vite-hono-plugin: add a `.catch()` to the initial `pump()` kickoff so a
sync throw before the first `await reader.read()` can't surface as an
unhandled rejection.
- sandbox_proxy.html: drop the stale CSP comment — v1.5's sandbox HTTP
server never set CSP either; this PR doesn't regress anything. Replace
with the actual isolation model (iframe sandbox attribute + origin
allowlist) so future readers don't assume a CSP header is enforced.
- Hoist `WebServerHandle` to a shared `server/types.ts` so the future
launcher port (#1246) doesn't need to pick one of two duplicate
declarations.
- Extract `resolveAutoOpen()` helper out of the triple-nested ternary in
`buildWebServerConfigFromEnv` for legibility, with the three-way logic
documented in one place.
- Add an inline comment explaining why
`webServerConfigToInitialPayload` falls back to streamable-http for
unknown discriminators (forward-compat with future SDK transports)
rather than throwing.

* test: switch integration project to folder-based manifest (#1314)
Replace the `integrationTests` enumeration in vite.config.ts with a
folder glob (`src/test/integration/**/*.test.ts`). Files under that
folder run in the integration vitest project (node env, 30s timeouts);
everything else runs in the unit project (happy-dom).
This removes the silent misclassification trap from #1307: a new
integration-style test no longer falls into the unit project (and
happy-dom) just because someone forgot to add it to the array.
The 13 ported v1.5 tests + their helpers move under src/test/integration/
in a strict mirror of core/ source layout (mcp/, auth/, auth/node/,
storage/). Renames use git mv so history is preserved.

* test: address PR review on #1318 (glob extensions + AGENTS doc)
- vite.config.ts: widen integrationGlob from `*.test.ts` to
`*.test.{ts,tsx}` so the integration folder fully owns its contents.
Without this, a `.test.tsx` placed under src/test/integration/ would
match the unit project's `{ts,tsx}` include, fail the unit `.ts`-only
exclude, and silently land under happy-dom — the exact misclassification
trap this PR set out to close.
- AGENTS.md: update the line describing where integration tests live;
it still pointed at the old `src/test/core/` location and the removed
`integrationTests` enumeration.

* feat(test): run v1.5-ported integration tests under node-env vitest (#1307)
Adds an `integration` vitest project alongside `unit` and `storybook` so
the 13 v1.5-ported tests that need real HTTP/stdio servers (or fail under
happy-dom's SDK mock resolution) run again under node env with 30s
timeouts. Restores test-servers/ as a buildable package so the stdio
subprocess spawns a real .js file. Drops the v1.5-source `coverage.exclude`
globs and fills coverage gaps across the v1.5-ported core/ modules; two
large files (inspectorClient.ts, remote/node/server.ts) keep narrow
per-file excludes tracked in #1310.

- Drop `baseUrl` / `paths` / `typeRoots` / `declaration*` from
test-servers/tsconfig.json. They were only needed for type
resolution, and we already pass `--noCheck` from `test-servers:build`.
Under TS 6+ the deprecated `baseUrl` exited with code 2, which
silently skipped vitest in the `&&` chains of test:integration /
test:coverage / validate.
- Rework the "send() throws after closed" test to drive `closed` via
an actual transport_error SSE event instead of mutating private
state through a cast — matches the real path the branch guards.

- auth/ + auth/browser/ + auth/node/ + auth/remote/ (16 files)
- mcp/config.ts + mcp/node/ (4 files, stdio transport)
- mcp/remote/ + mcp/remote/node/ (12 files, HTTP/SSE transport)
- mcp/inspectorClient.ts (~2169 LOC), messageTrackingTransport,
fetchTracking, oauthManager, index, state/index
Total: ~7,800 LOC of source files, copied unmodified via
`git show origin/v1.5/main:<path> > <dest>`.
Also:
- Add deps: pino, hono, @hono/node-server, atomically, zustand, @types/node
- tsconfig.app.json: extend paths to resolve new node-only deps from
core/, add "node" to types, disable erasableSyntaxOnly (v1.5 code
uses parameter properties — TODO to re-enable in follow-up)
Compiles down to 47 type errors, all in three categories:
- 24 TS2305: v2 dropped v1.5 type exports (InspectorClientOptions,
CreateTransport, InspectorClientEnvironment, AppRendererClient,
SamplingCreateMessage class, ElicitationCreateMessage class,
jsonUtils helpers, OAuth events). Per user direction, will re-add
these to v2's diverged files (types.ts, samplingCreateMessage.ts,
etc.) so the ported code stays verbatim.
- 15 TS7006: implicit-any params in v1.5 code (v1.5 tsconfig was
looser than v2's noImplicitAny). Need explicit annotations.
- 8 other TS errors: ../package.json import, Transport|null narrowing,
hono Context generic mismatch, one unused parameter.

* wip(core): integrate ported v1.5 InspectorClient + port tests (#1302)
Source integration (typecheck + build now pass):
- Re-add v1.5 types/classes dropped during v2 evolution:
- types.ts: CreateTransport*, AppRendererClient, InspectorClient{Environment,Options}
- samplingCreateMessage.ts / elicitationCreateMessage.ts: classes + keep v2's
InspectorPending{Sampling,Elicitation} interface
- inspectorClientEventTarget.ts: oauth* event keys
- json/jsonUtils.ts: convertParameterValue / convertToolParameters /
convertPromptArguments + ParameterSchema
- inspectorClient.ts: replace `../package.json` import (v2 has no
core/package.json) with a hardcoded identity constant
- remote/node/server.ts: cast hono Context for streamSSE (hono's
generic typing tightened since v1.5)
- oauth-callback-server.ts: drop unused hostname field
- tsconfig: enable @types/node, add paths for new bare-module deps
(pino, zustand, hono, atomically) in app + test configs
- vite.config.ts: mirror those module aliases for the unit project
(which runs from repoRoot)
Tests ported (19 files, ~11K LOC) under clients/web/src/test/core/:
- All core/__tests__/auth/* (7 files)
- inspectorClient.test.ts + 4 OAuth variants
- mcp/oauthManager.test.ts, jsonUtils.test.ts
- transport, remote-transport, remote-server-config, storage-adapters
- helpers/oauth-client-fixtures.ts
Bulk-rewrote `from "../mcp/…"` → `from "@inspector/core/mcp/…"` etc.
Current state:

- build: passes (vite v8, 788 modules)
- unit tests: 1014 / 1034 pass (937 pre-existing + 77 new core tests)
- 20 failures in 13 files; failure modes:
- 13 file-load failures needing the v1.5 `test-servers/` package
(@modelcontextprotocol/inspector-test-server) which isn't in v2 yet
or real fs/network not available in happy-dom
- 7 assertion failures in discovery.test.ts + state-machine.test.ts

* wip(core): port test-servers, more types, partial test integration (#1302)
- Port v1.5 test-servers/ package (12 files, ~5K LOC) under
repo-root/test-servers/, wire @modelcontextprotocol/inspector-test-server
alias in both vite.config.ts (regex form) and tsconfig.test.json.
- Add deps: express ^5, yaml ^2, @types/express ^5.
- Re-export InspectorClientOptions/Environment/Transport* from inspectorClient.ts
so v1.5 tests that import them from that module path keep resolving.
- Switch InspectorClientEventMap to use SamplingCreateMessage /
ElicitationCreateMessage classes (matches v1.5 event payload contracts)
while keeping the InspectorPending{Sampling,Elicitation} interfaces in
the *.ts modules for v2 consumers that still use them.
- Fix verbatim-module-syntax issue in test-servers and drop unused stdio
config field.
- Adjust inspectorClient.test.ts task types to TaskWithOptionalCreatedAt
(SDK 1.29 tightened Task shape vs v1.5's 1.25).
- Drop spurious maxMessages/maxFetchRequests/maxStderrLogEvents from
remote-transport.test.ts (never on InspectorClientOptions).
State:
- typecheck: 0 errors
- build: passes
- unit tests: 1099 / 1270 pass
- 171 failures in 10 test files, almost all integration tests that need
real HTTP/fs/network (happy-dom can't host them). Next: add a node-env
vitest project to run these properly.

* feat(core): port v1.5 InspectorClient + transports + auth subsystem (#1302)
Bulk-port of the v1.5 core runtime (~7,800 LOC source + ~16K LOC tests +
~5K LOC test-servers/) into v2. Files copied verbatim from origin/v1.5/main
via `git show >`; only minimal adapters added on the v2 side.
Subsystems landed
-----------------
- core/logging/, core/storage/, core/auth/ (browser + node + remote)
- core/mcp/ runtime: inspectorClient.ts (2169 LOC), oauthManager,
messageTrackingTransport, fetchTracking, config, index
- core/mcp/node/ (stdio transport)
- core/mcp/remote/ + remote/node/ (HTTP/SSE transport + Hono server)
- test-servers/ package (composable MCP test servers, fixtures, harness)
v2 adapter layer
----------------
- types.ts: append CreateTransport*, AppRendererClient,
InspectorClient{Environment,Options} (v2 had pruned these — v1.5 needs them)
- samplingCreateMessage / elicitationCreateMessage: keep v1.5 classes AND
v2's Inspector Pending* interfaces in the same files
- inspectorClientEventTarget: add oauth* event keys; switch pending
sampling/elicitation payloads to the classes (matches v1.5 contracts)
- json/jsonUtils: append convertParameterValue/convertToolParameters/
convertPromptArguments + ParameterSchema
- inspectorClient.ts: re-export Options/Environment/Transport* so tests
that import these from `inspectorClient.js` keep resolving; replace
`../package.json` import with a hardcoded identity (v2 has no core/package.json)
- remote/node/server.ts: cast hono Context for streamSSE (hono generic
tightened since v1.5)
- oauth-callback-server: drop unused hostname field
- tsconfig.app.json / tsconfig.test.json: add @types/node + paths for
pino/zustand/hono/@hono/node-server/atomically/express/yaml, disable
erasableSyntaxOnly (parameter-property syntax from v1.5)
- vite.config.ts: regex-form module aliases (so the package's exports
field handles subpaths like `hono/streaming`, `zustand/middleware`),
alias for @modelcontextprotocol/inspector-test-server → test-servers/src
Tests
-----
- 19 v1.5 test files copied under clients/web/src/test/core/,
imports rewired to @inspector/core/* and @modelcontextprotocol/inspector-test-server
- 1004 unit tests pass; 298 storybook tests pass; coverage gate passes
Known follow-ups (out-of-scope here, tracked in TODOs)
------------------------------------------------------
- 13 integration test files are excluded from the unit project (spawn real
HTTP/stdio servers; run real OAuth flows; mock SDK auth → happy-dom CORS).
Needs a node-env vitest project. Files listed under `test.projects[0].test.exclude`.
- Source files exercised only by those integration tests are excluded from
the coverage gate pending the node-env project. Listed under
`test.coverage.exclude` with comment.
- Manual smoke tests against real stdio / HTTP / OAuth server per the AC
on #1302 still need verification locally.

* docs/fix: address #1306 review (AGENTS tree, #1307 links, @types/node, .substr)
- AGENTS.md: expand the project-structure tree to include all v1.5-ported
subsystems (core/auth/{browser,node,remote}, core/storage, core/logging,
core/mcp/{node,remote/{,node}}, core/mcp/state) plus the new top-level
test-servers/ directory (with a note about its @modelcontextprotocol/
inspector-test-server alias).
- vite.config.ts: reference #1307 from both the test exclude block and the
coverage exclude block so the next person editing either sees the
marching order for shrinking the lists.
- package.json: restore @types/node to ^24 (an earlier `npm install
--save-dev @types/node@^22` accidentally pinned it lower than the repo
was using; nothing here required ^22).
- core/mcp/fetchTracking.ts: replace deprecated .substr(2, 9) with
.slice(2, 11) to match the convention in core/mcp/inspectorClient.ts.

* ci(storybook): wire test:storybook into CI (#1251)
- Add test:storybook:watch to clients/web for interactive iteration; the
one-shot script already existed.
- Surface test:storybook at the repo root, delegating to the web client.
- Add a separate CI step that installs the Playwright Chromium binary
and runs the storybook play-function suite after validate. Kept out of
validate because the suite needs a real browser and is ~10s slower
than the unit tests.
- Document the new pre-push step in AGENTS.md.

* ci(storybook): cache Playwright browsers + tighten AGENTS wording
Cache the Chromium binary keyed on clients/web/package-lock.json so the
~150MB download is a no-op on CI cache hits. Also clarify that CI runs
test:storybook after the unit/lint/build checks (not literal `validate`,
which is a local-only script).

* test(coverage): bootstrap vitest unit infra and add tests at 90%+ per file (#1245)
Establishes the unit-test runtime AGENTS.md mandates: a vitest "unit"
project alongside the existing storybook project, RTL + jest-dom +
happy-dom, a Mantine-aware render helper, and a 90%-line per-file
coverage gate enforced by CI. Adds 66 test files covering all 62
components under elements/groups/screens/views, plus core/mcp and
clients/web/src/utils. Total: 577 tests, 98.7% line coverage globally.

* test(coverage): address PR #1269 review feedback
- AGENTS.md: correct coverage gate description (lines ≥ 90, statements ≥ 85,
functions ≥ 80, branches ≥ 50) with rationale for the relaxed branch
threshold
- InspectorView.test.tsx: document what the Math.random() mock values
(0.1 / 0.99) control vs. STUB_SUCCESS_RATE in InspectorView.tsx
- vite.config.ts / tsconfig.test.json: drop unused `globals: true` and the
`vitest/globals` type now that every test file imports describe/it/expect/vi
explicitly; manual `afterEach(cleanup)` in setup.ts remains required because
testing-library auto-cleanup relies on globalThis.afterEach

* docs(agents): require version label on new issues and PRs (#1256)
Recent v2 PRs (#1247, #1249, #1250, #1252, #1255) all landed without a
v2 label, making version-filtered queries unreliable. Codify the
expectation directly in the issue-driven workflow: each branch / board
gets a fixed label, and the label is set at create time via the
gh create flag rather than backfilled.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* Also fix stale "PR against main" line
The PR-target line still said "Open a PR against main", which is
correct only for v1 work. Mirror the version-label mapping above so
the PR base matches the board.
