It appeared in all five lockfiles — the root plus each of the four clients, none of which is an npm workspace, so all five had to move together. Deferred from the pre-2.0.0 sweep because it is dev-scope, not attacker- controlled, and a major bump across five packages was the wrong thing to attempt immediately before an irreversible publish. This is that work. ## What moved - `eslint` `^9.39.4/5` → `^10.8.0` and `@eslint/js` → `^10.0.1`, in all five manifests. - `eslint-plugin-react-hooks` `^7.0.1` → `^7.1.1` in web and tui. Required, not cosmetic: 7.0.1's peer range stops at `^9.0.0`, so installing it alongside eslint 10 fails `ERESOLVE`. - Everything else already declared eslint 10 support and stayed put: `typescript-eslint@^8.56.1` (`^8.57 || ^9 || ^10`), `eslint-plugin-react-refresh@^0.5.2` (`^9 || ^10`), `eslint-plugin-storybook@^10.2.19` (`>=8`). ## Config migration None was needed. All five configs were already flat (`eslint.config.js` with `defineConfig`/`globalIgnores` from `eslint/config`), which is the format v10 keeps and the only one it still supports. The root config's `core/` and shared- surface blocks — including the `_`-prefix `argsIgnorePattern` / `varsIgnorePattern` / `caughtErrorsIgnorePattern` — are unchanged and still gate `lint:core` and `lint:shared`. No rule was disabled, downgraded, or scoped away to make the new eslint pass. v10 surfaced 21 real violations across three rules; all 21 are fixed in the code. ### `preserve-caught-error` (new in `eslint:recommended`) — 15 sites A `throw new Error(msg)` inside a `catch` silently drops the original error. Each now passes `{ cause }`, so the underlying failure survives into the chain. Messages are unchanged, so nothing that asserts on them moves. 12 in `core/`, 2 in `clients/cli`, 1 in `test-servers/src`. ### `no-useless-assignment` (new in `eslint:recommended`) — 2 sites `clients/cli/src/cli.ts`'s `optionArgs` and `test-servers/src/test-server-oauth` 's `valid` were initialized and then unconditionally overwritten on every path. Both are now declared without the dead initializer; TypeScript's definite- assignment analysis covers the remaining paths. ### `react-hooks/set-state-in-effect` — 8 sites (web) These were false negatives the plugin fixed in 7.1.0, not a rule we newly opted into: `set-state-in-effect` has been `error` in `flat/recommended` since 7.0.1, and the web config has always extended it. Every one was the same anti-pattern — resetting or re-syncing local state from a prop inside a `useEffect`, which paints the stale value for one frame and then renders again to correct it. All eight now use a new `useValueChange(value, onChange)` hook (`clients/web/src/hooks/useValueChange.ts`), which is React's documented "adjusting state during render": compare against the previous render's value with `Object.is` and call back *during* render, so React discards the in-progress output before it reaches the DOM. - `MrtrConversation`, `ProtocolEntry`, `TaskCard` — mirror `isListExpanded`. - `NetworkEntry` — same mirror, plus the "Reveal in Network" force-open. The reveal's rAF scroll stays an effect (real external-system work); only the `setIsExpanded(true)` moved. `isExpanded` is now seeded from `isListExpanded || revealed`, since a render-time sync fires on change and so cannot cover an entry that mounts already revealed. - `PromptArgumentsForm`, `ResourceTemplatePanel` — reset on template/prompt switch. - `ServerConfigModal` — reset on open. Keyed on `opened ? initial : undefined`, which collapses "opened flipped" and "initial changed while open" into one value; `initial` is already memoized, so it cannot thrash. `useValueChange` has its own test file, and `ServerConfigModal` gains an open→edit→close→reopen test (the close leg was previously untested, which is what left the new guard uncovered). ## Advisory delta `npm audit`, per package, before → after: | Package | before | after | | ------------------- | -------------------------- | -------------------------- | | root | 9 (1 low, 6 mod, 2 high) | 8 (1 low, 6 mod, 1 high) | | `clients/web` | 19 (3 low, 6 mod, 6 high, 4 crit) | 17 (3 low, 6 mod, 4 high, 4 crit) | | `clients/cli` | 6 (2 low, 4 high) | 4 (2 low, 2 high) | | `clients/tui` | 4 (1 low, 3 high) | 2 (1 low, 1 high) | | `clients/launcher` | 3 (3 high) | 1 (1 high) | `brace-expansion` is gone from all five — `eslint@10` resolves `minimatch@10` → `brace-expansion@5.0.9`. Dropping `@eslint/eslintrc` (removed in v10) also took `js-yaml` with it, clearing GHSA-52cp-r559-cp3m (high) from all four clients as a bonus. The remainder are unrelated and tracked separately. `npm run ci` passes end to end — validate, the per-file ≥90 coverage gate, the build gate, all five smokes (including `smoke:tui`, run locally on a real TTY), and 462 Storybook tests. Also documents the effect rule in AGENTS.md and mirrors it into `.github/copilot-instructions.md`, since it is now something a reviewer cites.

Because the callback is what updates state, that is not merely a wasted render — it is an infinite loop. Every current caller passes a primitive (`boolean`, `string`) or an already- memoized value, so nothing changes behaviorally. But the hazard was implicit, and the next caller is the one it would bite. Documented on the hook itself, and one clause added to the AGENTS.md rule with its mirror in `.github/copilot-instructions.md`. No runtime guard: the requirement is the same one a `useEffect` dependency array carries, and here the failure is loud and immediate rather than silent. `npm run ci` passes.

A `catch` binding is `unknown`, so that cast is an assertion rather than a check — a thrown non-Error would render `--tool-args-json is not valid JSON: undefined`, which points the user at nothing. `JSON.parse` does only throw `SyntaxError` today, so this is not a live bug. But the cast is the kind AGENTS.md asks us not to leave unjustified, the same handler was already being touched here to add `{ cause: e }`, and every other site in this PR uses the guarded form. Now it does too. `npm run ci` passes.

A callback doing anything external would run an unpredictable number of times, and concurrent React can abandon an in-progress render entirely. Every current caller already passes a callback that only calls `setState`, so nothing changes. But "runs during render" is the whole point of the hook and the constraint that follows from it was left implicit. Stated on the hook, with the same clause in the AGENTS.md rule and its `.github/copilot-instructions.md` mirror. All three now point at `NetworkEntry` as the worked example of the split: the reveal's force-open is a state update and lives in `useValueChange`, while its `requestAnimationFrame` scroll stays a `useEffect`. `npm run ci` passes.

Cliff Hall	c2af547cc8	fix(core): register peer-request handlers before connect (#1797) (#1798) ... * fix(core): register peer-request handlers before connect (#1797) The roots/sampling/elicitation capabilities are advertised on the SDK `Client` at construction, so from the moment `connect()` sends `notifications/initialized` the server may issue any of those requests. The handlers, however, were registered after the handshake resolved and after `fetchServerInfo()` — leaving a window in which the SDK answered `-32601 Method not found`. `server-filesystem` asks for `roots/list` the instant it is initialized (that is how it learns its allowed directories) and lost the race, so it silently fell back to its CLI-argument directories instead of the roots configured in the Inspector. `server-everything` asks later and did not. Extract the four peer-request handler blocks into `registerPeerRequestHandlers()` and call it before `client.connect()`. None of them depend on server capabilities — only on constructor-set state. The notification handlers that do gate on `this.capabilities` stay in `connect()`, after `initialize`. Regression test drives the race deterministically with a fake transport that delivers `roots/list` synchronously from inside the `send()` of `notifications/initialized`; it fails on the pre-fix ordering. Closes #1797 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_011TrCvpunxToe7qnppk6zwr * review: round-1 fixes — pre-connect roots/list_changed, wider timing test (#1797) Finding 1: `notifications/roots/list_changed` was the one handler in the post-handshake block that gates on nothing but constructor state, so it sat in the same race — a server emitting it right after `initialized` had it silently dropped (no wire error; the symptom is a missed UI refresh). Moved to a new `registerPeerNotificationHandlers()` called next to `registerPeerRequestHandlers()` before `connect()`. Finding 2: the timing test asserted one of the four moved handler blocks. It now injects `tasks/list` and the `roots/list_changed` notification in the same burst as `roots/list`, so moving any of the block back after `connect()` fails the test. Sampling/elicitation stay out — they park a pending request awaiting user input and have no reply to assert on. Dropped the unused `sessionId`/`setProtocolVersion` transport fields. Verified the added assertions are load-bearing: the notification assertion fails against the previous commit, the `roots/list` one against `origin/v2/main`. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_011TrCvpunxToe7qnppk6zwr * review: round-2 fixes — correct the roots/list_changed premise (#1797) The round-1 doc comment claimed a server may emit `notifications/roots/list_changed` at initialize. It can't, normally: `RootsListChangedNotificationSchema` is a member of `ClientNotificationSchema` and absent from `ServerNotificationSchema` — the client sends it (setRoots does, at :4251). The inbound handler is defensive coverage for a non-conformant server, and dispatches `rootsChange` with our own already-known roots. Reworded the method doc and the test's header so neither states the false premise; the move itself stands (it gates on no server capability, so it belongs with the request handlers). Also from review: - Dropped the vacuous `notificationRejected` flag and its inverted comment. The SDK does not throw for an unregistered notification, so the try/catch could never observe one — confirmed by bisect, where the pre-fix failure was always `rootsChanges`, never the flag. Removing the catch also stops it swallowing a genuine throw from the injected requests. - Narrowed `replies` to responses (`"result" in message || "error" in message`) so it can't also collect client-originated requests. - Annotated the unreachable `if (!this.client)` guard with a justified `v8 ignore` per the AGENTS.md dead-guard policy. Re-verified both regression directions: the `roots/list` assertion fails against `origin/v2/main`, the `rootsChange` one against `55e25b7c`. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_011TrCvpunxToe7qnppk6zwr * review: round-3 fix — drop stale comments inside the roots handler (#1797) The four inline comments moved verbatim with the handler contradicted the method doc reworded one round earlier: they said "server's roots" (they are ours — it is a ClientNotification) and "we'll just dispatch an empty array", which is not what `this.roots || []` does when roots are configured. The new timing test asserts exactly that non-empty dispatch. Replaced with one accurate line. Comment-only. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_011TrCvpunxToe7qnppk6zwr * fix(cli): advertise roots so roots/set is actually serviceable (#1797) Round-4 review found the same -32601 symptom on a second path: the CLI constructed its InspectorClient with no `roots` option, so `capabilities.roots` was never advertised and no `roots/list` handler was registered — yet `--method roots/set` calls `setRoots()`, which announces `notifications/roots/list_changed` to the server. A server taking up that invitation got "Method not found", after the CLI reported success. The review's suggested fix — register `roots/list` unconditionally — is not implementable: the SDK asserts the client capability inside `setRequestHandler` ("Client does not support roots capability"), so it throws during connect for any client built without the option, and `registerCapabilities` refuses to run after connect. A client that omits `roots` therefore cannot legally serve `roots/list` at all. Fixed at the layer that can fix it: `cli.ts` seeds `roots: []`, matching web (`App.tsx` always passes it). The core registration stays gated on the constructor value, now with the SDK constraint documented so the next reader doesn't retry the unconditional version. `setRoots()`'s doc claimed it "will enable roots capability if it wasn't already enabled" — it cannot, for the reasons above. Corrected, and dropped the dead `if (this.roots === undefined) this.roots = []` the very next line overwrote. Tests: a CLI test drives `list_roots` over an HTTP test server (verified load-bearing — without the seed it fails on the -32601 error text), and the core timing test gains a case pinning that roots set after connect are served with the current values, not the constructor's. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_011TrCvpunxToe7qnppk6zwr * fix(cli,tui): advertise the roots configured in mcp.json (#1797) Round-5 review: seeding `roots: []` fixed the -32601 but not the outcome. `server-filesystem` discards an empty roots answer (`validatedRootDirs .length > 0`) and keeps its CLI-argument directories — which is the symptom this PR set out to fix. The user's roots were already in hand two lines away, on `serverSettings.roots` (lifted from mcp.json by `mcpConfigToServerEntries`). Now passed through `cleanRoots`, the same shared helper web uses, so both clients answer `roots/list` byte-identically for the same config. This matters most on the CLI because it is one-shot: `--method roots/set` sets roots on a connection torn down a few statements later, so the config file is the only durable way to give a run its roots. Same gap in the TUI (`App.tsx` built its options with no `roots` key at all), fixed the same way. The review suggested a follow-up issue for it; folding it in here instead, since it is the identical line and splitting it would leave a known-wrong client in tree. Also from review: hoisted `waiters` up with the other fields, and `injectRequest` now rejects after 1s naming the method and id rather than hanging to the vitest timeout. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_011TrCvpunxToe7qnppk6zwr * review: round-6 fixes — document roots in the CLI README, harden cleanRoots (#1797) - clients/cli/README.md enumerated the settings lifted from a catalog/config file without roots. Roots are the least discoverable member of that list — there is no flag, and `--method roots/set` dies with the connection — so the file is the only durable way to supply them. Said so. - cleanRoots() trusted its input's shape. `Root[]` is a compile-time type over hand-editable mcp.json, and as of this PR all three clients feed it straight from disk, so `"roots": [{"name":"Work"}]` or `"roots": "file:///work"` threw at connect. Non-array bails to []; an entry without a string uri is dropped with a warning. Hardened in the one shared place rather than three call sites. Review suggested a follow-up issue; folded in for the same reason as the TUI fix last round. - Test comment said the CLI passes a `roots: []` seed — true one commit ago. - injectRequest clears its timeout on reply (an armed timer outliving a test is the #1760 teardown class), and setRoots' doc drops the "despite what this comment used to claim" archaeology. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_011TrCvpunxToe7qnppk6zwr * review: round-7 fix — cleanRoots also throws on a non-string name (#1797) The round-6 hardening guarded `uri` and left `name` throwing one line later: `r.name?.trim()` guards null/undefined, not "is a string", so `"roots": [{"uri":"file:///a","name":42}]` still died at connect — the same crash class, one field over, reachable from all three clients and the web settings-save path. Reproduced against the shipped function body before fixing. A bad `name` now costs the name, not the root (it is optional, and the uri is still usable), with a warning. The doc no longer overstates what is validated. Also from review: the CLI test comment said "`cli.ts` now seeds `roots: []`" — true only of that ad-hoc test's path; and the registration comment's `(:588)` line reference is now a durable name. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_011TrCvpunxToe7qnppk6zwr * fix(core): normalize roots in setRoots() too (#1797) Round-8 review: this PR made cleanRoots the single normalizer for roots at connect and at save, but setRoots — the third way roots enter the client — did a bare `this.roots = [...roots]`. Web cleans at its call site; the CLI does not, so `--method roots/set --roots-json '[{"name":"Work"}]'` stored a root with no uri, advertised it in the roots/list reply, and echoed it back as success. cleanRoots is idempotent, so calling it inside setRoots covers the CLI without disturbing web's pre-clean, and all three entry points now agree. Review filed this as an optional follow-up; folding it in for the same reason as the TUI and cleanRoots items — it is smaller than the issue describing it. Test asserts the malformed entry is dropped and the valid one survives; verified load-bearing against the bare-spread version. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_011TrCvpunxToe7qnppk6zwr * review: round-9 fixes — normalize roots in the constructor too (#1797) The round-8 commit claimed "all three entry points now agree"; review pointed out the constructor is a fourth, and the only one still raw. All three clients clean at their call site, so nothing was broken — but the invariant was enforced by convention rather than by the class, at the very entry point this whole thread started from. `this.roots` now runs through cleanRoots, with a ternary so the `undefined`-vs-`[]` distinction that gates capabilities.roots survives. Also from review: - The CLI roots/set test provoked a cleanRoots warning without suppressing it (AGENTS.md). Suppressed, and the spy now asserts the drop was reported rather than silent. - `enables roots when previously undefined …` in coverage-backfill was named after behaviour round 5 established does not exist. Renamed, with a comment on what that client actually can and cannot do. - setRoots dispatches a copy to rootsChange, as getRoots() already did, so a listener can't push into the list we advertise. - run-method.test.ts's connectStdio now passes `roots: []` like cli.ts, so the helper matches the client shape production builds. Verified load-bearing: the constructor test fails against the raw assignment. validate / coverage / build-gate / smoke / storybook all green (run as separate stages — full `npm run ci` kept being killed mid-coverage by the environment). Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_011TrCvpunxToe7qnppk6zwr * review: round-10 fixes — copy at both rootsChange dispatches (#1797) Round-9 claimed setRoots' copy closed the "a listener can't push into the list we advertise" hole. It closed one of two sites: my reply conflated the notification handler's *dispatch* with the roots/list *request* handler — the latter is serialized to the wire immediately and is fine, the former hands listeners the internal array. Both copy now. Also from review: dropped the `({}) as never` in the new constructor test for the real factory the sibling tests use (this test never connects, so it is never invoked), and the needless `async` on it. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_011TrCvpunxToe7qnppk6zwr * review: round-11 doc fixes; merge v2/main (#1797) - cleanRoots' opening sentence still framed it as the settings-form normalizer, contradicting the paragraph below it that says every client feeds it from disk. It has four callers now; says so. - Marked the two runtime guards `Keep:` with the reason. The `Root[]` parameter narrows both to `never`, so "the compiler says this can't happen" is the argument someone will use to delete the checks rounds 6-7 installed. The reason now lives where the deletion would happen. - Noted the constructor-normalization case in the timing test's header, so it is discoverable from a file otherwise about the initialized race. Also merged origin/v2/main (#1796, loopback binding), which had advanced by one commit and touched the smoke scripts. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_011TrCvpunxToe7qnppk6zwr * fix(core): clear queued peer requests when connect() fails (#1797) Round-12 review found a second-order consequence of the handler move. Before it, registration happened after every await in connect(), so the moment a peer request could be queued the connect could no longer fail — queue and failure path never overlapped. Registering before the handshake puts both the handshake and the post-connect `setLoggingLevel` inside that window. The catch sets status to error and drops the transport but never cleared pendingSamples/pendingElicitations; only disconnect() does, and connect() reaches it solely on the connect-timeout path (not the default). So a server that elicits at `initialized` and then fails the connect left a live pending-request modal on a dead connection — web derives it from the queue lengths with no status gate — and the elicitation's cancel() never fired, hanging any awaitUrlElicitation waiter. Extracted disconnect()'s clear-and-cancel into clearPendingPeerRequests() and called it from the catch, dispatching the change events so the UI drops the modal. CLI/TUI are unaffected either way (sample/elicit off). Test note: the first version of this test passed with and without the fix — its `requestedSchema` omitted `properties`, so the SDK rejected the inbound params and nothing was ever queued. Fixed the fixture; it now fails without the change with a queued ElicitationCreateMessage. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_011TrCvpunxToe7qnppk6zwr * fix(core): clear the peer-request queue on a mid-session crash too (#1797) Round-13 review, two items. The test asserted only `getPendingElicitations()`/`getPendingSamples()`, which read the arrays directly — but the arrays are not what removes the modal. `usePendingClientRequests` tracks its own state off the pendingSamplesChange/pendingElicitationsChange events, so a regression that cleared without dispatching would strand a live modal on a dead connection and stay green. Both tests now assert the events fired with an empty payload; verified by deleting just the dispatches, which fails them. The connect-failure fix left the other way a connection ends uncovered: a mid-session crash goes through the transport's `onclose`, which sets status and fires `disconnect` but never touched the queues. Same two hazards, and arguably more reachable. `clearAndAnnouncePendingPeerRequests` wraps the clear plus its events, guarded on a non-empty queue so the paths that overlap (a connect failure whose dropCachedTransport also fires onclose) announce once; called from both. New test queues an elicitation, fires onclose, and asserts the queue and the event — fails without the change. Review flagged the crash path as a follow-up; folding it in, as with the earlier out-of-scope items — it is the same seam and three lines. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_011TrCvpunxToe7qnppk6zwr * review: round-14 fixes — make both teardown paths agree (#1797) - The crash path's comment claimed "cleared before the `disconnect` event so a consumer sees an empty queue" while disconnect() cleared *after* its own dispatch — an invariant stated as a property and held at one of two sites, the same shape as the round-10 finding. Moved disconnect()'s clear above its status/disconnect block so both paths agree; its change events stay batched with the other teardown dispatches. Full gate green, so nothing depended on the old ordering. - clearPendingPeerRequests' doc still named the `connect()` failure path as a caller; that path now goes through clearAndAnnouncePendingPeerRequests. Names the two real callers. - The mid-session test waited on `await Promise.resolve()` — the microtask-counting pattern this file replaced with injectRequest two rounds ago, working today only because the enqueue happens exactly one tick deep. Waits on the client's own `newPendingElicitation` instead. - The file header still called the constructor case "the last case"; it is third of five, and the two teardown cases went undescribed. Rewritten. - Restored the missing blank line between two tests, and noted why the sampling-event assertion holds for a queue that never held anything. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_011TrCvpunxToe7qnppk6zwr * review: round-15 fixes — scope the parity claim to the arrays (#1797) Round-14 made the two teardown paths agree on when the queue is cleared, and the comment then claimed parity flatly. It holds for the arrays but not the events: the crash path announces before `disconnect`, while disconnect() batches its change events with the rest of its teardown, so they land just after. Since the events are what drives the modal, the distinction matters to the next reader. Scoped the comment rather than un-batching — un-batching would trade a documented ordering for a real behaviour change with no gain. Same rule as round 14, one level down: check the other site, then check the other axis. Also gave the new `newPendingElicitation` wait the timeout that `injectRequest` documents, so a regression that stops the enqueue fails at the wait instead of hanging to the vitest timeout. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_011TrCvpunxToe7qnppk6zwr * test: pin disconnect()'s clear-before-announce ordering (#1797) Round-14 moved clearPendingPeerRequests() above disconnect()'s status block so a `disconnect` consumer sees an empty queue on both teardown paths, and round 15 documented it — but nothing enforced it. The existing `disconnect` listeners only count events, and the two teardown tests cover the crash and connect-failure paths, neither of which goes through disconnect(). So the one behavioural change in the stack was untested in both directions, and the tidy that undoes it (regrouping the clear with the batched change events) would have stayed green. Test records the queue length from inside a `disconnect` listener; the fixture's close() never fires onclose, so it exercises disconnect()'s own ordering rather than the crash path. Verified against the pre-round-14 position: `expected 1 to be +0`. Folded the newPendingElicitation wait into a shared helper now that two tests use it. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_011TrCvpunxToe7qnppk6zwr * test: pin disconnect()'s announce as well as its clear (#1797) Round-16 pinned the array half of disconnect()'s teardown and left the events unpinned — and nothing else in the suite covers them, so deleting disconnect()'s two change-event dispatches would have left a live modal after a user-initiated disconnect with the suite green. That is the path most likely to have a modal open when it runs. Asserted after the await rather than inside the disconnect listener, since disconnect() batches the events deliberately; verified by deleting the dispatches (`expected undefined to be +0`). Header rewritten by category rather than position: it has now gone stale twice in three rounds because it counted tests ("the last two") and enumerated paths that a new test falsified. It names the three teardown paths and what distinguishes them instead.

True only if "announcing" means the `disconnect` event: the connect-failure path emits none at all, and both it and the crash path clear after their `statusChange`. Scoped to what's true. Same shape as rounds 10/14/15 — a parity asserted in prose that holds on one of the axes it could mean — which is now the fourth time, in a sentence I wrote. ElicitationCreateMessage.cancel()'s doc still credited `disconnect()` teardown; this PR made clearPendingPeerRequests() its only caller, serving three paths. Re-attributed, and promoted the no-`onRemove` note to its own paragraph with the consequence spelled out — it quietly became a three-caller invariant during this PR, and "don't splice mid-iteration" reads like a style note until you know it would skip every other entry and leave those promises unsettled.

That throw lands before the handshake, so the client can never reconnect. Worse than the -32601 this PR started from: the connection is gone rather than answering one method badly. Not a regression (the same gate lived after the handshake before) and unreachable from the three shipped clients, which all pass roots. But core/ is a library surface, and the failure is unrecoverable. Gate now reads a construction-time `rootsCapabilityAdvertised` — the thing the SDK actually asserts on — so this.roots stays free to change. setRoots' doc says what does happen on such a client: the roots are stored and readable, but no server can ask for them. Also scoped the header's claim that the connect-failure path emits no `disconnect`: true of connect()'s own catch, but on a real transport dropCachedTransport's close() fires onclose first, which does dispatch one — making the catch's own call the auth-recovery backstop.

Adding any term to the advertisement condition would leave the flag true with `capabilities.roots` absent — the same unrecoverable wedge, reintroduced silently and in the throwing direction. Now read off the built capability object after it is assembled, so divergence is structurally impossible rather than merely absent. Verified the reconnect test still fails against the old `this.roots` gate. Also: named the capability-lifetime category in the test header (the new test was none of the three it listed), moved that test below the teardown group so the group stays contiguous, and rewrapped the over-long comment line.

Reproduced before fixing: CONNECT ERROR: Client does not support elicitation capability (required for elicitation/create) Since #1797 moved registration before the handshake, that throw means the client cannot connect at all. Same wedge as the roots one, one capability over, and reachable through a documented option value rather than a future edit. Gated on a new elicitationCapabilityAdvertised, derived from the built capability object exactly as the roots flag now is. Test constructs with `{ form: false, url: false }` and asserts connect() resolves; verified load-bearing. Also made the four construction-time capability inputs (sample, elicit, receiverTasks, advertisedExtensions) `readonly`. The round-19 bug was a mutator making a construction-time fact stale, so a future setter for any of these should be a compile error rather than a review catch.

A server taking the invitation gets -32601: the advertise-then-refuse shape this PR opened with, and the last place it survived. Now built from capabilities.sampling / capabilities.elicitation, both decided just above, with the key omitted entirely if neither applies. Also made the remaining three registration gates read the built capability object like the two from the last two rounds — sampling, tasks/*, and the URL-elicitation completion handler. None could diverge today, but a mixed convention means the next reader has to re-derive which gates are safe, and adding one condition to an advertisement block is exactly how elicitation broke. Five gates, one rule now. Test asserts a receiverTasks+elicit:false client advertises tasks.requests with sampling and without elicitation; verified load-bearing.

Second client in the same test asserts `tasks` survives (list/cancel are still serviceable) while `requests` is absent rather than empty; verified against `requests: taskRequests`. The header regained a numeral four commits after round 17 rewrote it by category to stop exactly that, and it was already stale. Dropped, and named the third category — advertise-only-what-you-serve, which is about the capability object rather than a registration gate.

Round 13 recorded the samples-vs-elicitations asymmetry as deliberate on two grounds: nothing internal awaits a sample, and the transport is gone by then. The first still holds; the second is false on one path, and it is a path this PR created. `connect()`'s catch drops the transport only when `!transportHasAuthProvider`, so on the HTTP+OAuth path — web's ordinary authenticated case — it is retained and the caller reconnects over it. A sampling request queued during the handshake was then discarded with the connection still live: no response frame ever written, and the server waits forever for a reply to a request we accepted. Accept-then-silence, which is worse for the peer than the -32601 this PR opened with. SamplingCreateMessage.cancel() mirrors the elicitation one — settles (rejects, what the UI's decline path already sends and the SDK turns into an error response) without calling onRemove, since the caller iterates the queue and clears it. clearPendingPeerRequests loops it like the elicitations. Also corrected two comments that assumed the catch always tore the transport down, and noted that the retention is gated on transportHasAuthProvider alone — independently of isConnectAuthRecoveryError, which gates only the status hold. Test asserts settlement rather than a wire frame, since on the disconnect() path the transport is closed before the settle; a later respond() throwing "already resolved or rejected" is the proof. Verified load-bearing.

That promise only gets a consumer when the server polls tasks/result, so a task sitting in input_required has no handler attached — and the settle added last commit surfaced as an unhandled rejection. Not hypothetical: the repo already worked around it test-side, with a helper that reaches into private state to attach no-op catches, whose comment describes this exact race. Fixed at the source instead — one `void payloadPromise.catch(() => {})` at creation, which also covers the pre-existing cancelReceiverTask path. Removed the now-redundant helper and its two call sites. Verified: dropping the source line makes that suite report two unhandled rejections. Corrected SamplingCreateMessage.cancel()'s doc — its "no response frame is ever written" rationale is true of the plain shape only; a task-augmented sample already answered the wire with a CreateTaskResult, so settling it is about not leaving the task in input_required limbo. Nits: generalized the enqueue wait helper to both events so the sampling wait gets the timeout the elicitation one has; moved the sampling teardown test back into the contiguous teardown group; named the settle property in the header; fixed the fixture doc that still claimed to record replies.

Removed. Also reworded the surviving .catch() in inspectorClient.test.ts: it is still needed, but as a value capture for the assertion, not for unhandled-rejection suppression. Rewrapped the teardown paragraph in the test header — my round-25 edit left a 104-char line, and two hand-fixes left it ragged, so it is reflowed in one pass.

Probed it: the premise is wrong. The SDK asserts the notification capability too — `notification()` rejects with "Client does not support roots list changed notifications" and nothing reaches the wire. No spec violation and no invitation; what actually happened is that setRoots provoked that rejection and logged it as "Failed to send", implying a transient failure where the truth is structural. Kept the early return on that corrected basis: it stops us provoking a rejection we know will come, and warns accurately instead. Doc and comment say the SDK is the enforcer rather than claiming this guard is what keeps the wire clean. The test pins the end state (no invitation for roots we can't serve) and passes either way — recorded as such rather than presented as a regression guard, since it isn't one. Also moved the advertise-category test below the two gate cases, matching the order the header introduces them.

Identical today (roots are only ever advertised as `{ listChanged: true }`), but a conditional advertisement would un-gate it silently, which is the round-21 shape again. Split into rootsListChangedCapabilityAdvertised, mirroring urlElicitationCapabilityAdvertised, which already reads its assertion's sub-field; rootsCapabilityAdvertised keeps the roots/list registration, where presence is what setRequestHandler checks. Also moved the new test out of the gate pair it had split — it is a runtime-emission case, not a registration-gate one — and extended the header's converse-category paragraph to cover notifications, which indexes it without inventing a category. Reflowed the setRoots doc paragraph in one pass (111-char line from the last commit, plus a ragged orphan from an earlier edit).

That reword happened in core/, but the same premise had been written into the two comments justifying the CLI's roots seed, and they still asserted it. Both now state the real pre-fix failure: a server asking for roots on its own got -32601, and roots/set could not announce at all. Also fixed the warn message under the round-28 gate: it named the roots capability while the gate is on roots.listChanged — precisely the pair that split was made to distinguish, so a client advertising `{}` would have been told it advertised nothing.

That map holds the modern tasks/* frames the SDK's era gate refuses to route, so the SDK's chained _onclose doesn't know about them: a Tasks-tab poll in flight when the server died waited out its own 30s timeout and reported a timeout for what was a crash, on a connection that had already dispatched `disconnect`. Pre-existing — both the map and the crash path predate this PR. Fixing it here because the invariant it violates is one this PR wrote down: "every path that ends a connection has to clear that queue, announce it, and settle each entry", in clearAndAnnouncePendingPeerRequests' doc and the timing test's header. One channel was true of one path out of three. Test starts a raw-wire request and fires onclose; without the call it hangs to the vitest timeout, which is the symptom. Checked the two siblings and left both: taskInputAbortControllers is already unblocked via the elicitation cancel the crash path performs, and activeToolCallAbortController rides an ordinary client.request the SDK settles itself.

It is unavoidable — rawWireRequest is private and every public route is gated on isTasksExtensionNegotiated(), which needs a modern handshake the fixture doesn't perform — so that reasoning is now written down instead of left to be re-derived. - `await Promise.resolve()` was a no-op: rawWireRequest registers its entry in the promise executor, synchronously, before any suspension. Dropped, which also makes the test pin that ordering rather than paper over it — and stops the third recurrence of the microtask-counting pattern this file's own helper doc argues against. - Moved the test into the teardown group and extended the header's teardown paragraph to cover the outbound direction, which it framed entirely as inbound.

Round 31 established that scoping so the code wouldn't imply an impossible state; the prose then un-scoped it. Split into its own paragraph with its own scope clause, and reflowed both in one pass rather than nudging breaks. Also raced the raw-wire assertion, for the reason the file's own wait helper documents: without the teardown rejection the test waited out the request timeout and reported a bare vitest timeout.

Extracted `withTimeout`, used by the enqueue wait and the raw-wire assertion; injectRequest keeps its own since its timeout also deletes the waiter entry. On the failing path the raw-wire test left the production 30s timer armed, so a regressed run got the intended failure plus a stray unhandled rejection up to 30s later — the armed-timer class the file's own comment names, on the failure path. `settled` is marked handled before the race. Verified: with the fix removed the run fails with "raw-wire request not settled by teardown" and no unhandled rejection. Recorded why disconnect() drains the SDK's in-flight requests but rejects the raw-wire map outright: the user asked to disconnect, and a Tasks poll is not worth delaying that for.

Both were wrong: `Promise.race` attaches a rejection handler to every input, so `withTimeout(settled, …)` on the next line already marks it handled. Verified with a standalone script — no unhandledRejection fires, and the pre-fix version was equally safe. Removed the line and the comment. The comment mattered more than the line: it told the next reader that `Promise.race` does not mark its losers handled, which is false and would cost them elsewhere. Kept the true half by setting `timeout: 50` on that test's client, so a regression leaves no 30s timer armed and fails with `Raw request "tasks/get" timed out after 50 ms` — more self-describing than the raced generic message.

Verified it isn't one: `safeDisconnectTimeout` defaults to 0 and the only caller anywhere that passes a value is a single test, so nothing is drained in production; and the drain polls the SDK's `_responseHandlers`, which never holds raw-wire ids, so those were never eligible regardless. Reworded to what is true. The framing came from my own round-33 reply, which described the drain as running on every disconnect — a comment faithfully encoding a half-read mechanism, which is the same failure as the `Promise.race` one it followed.

Reworded: the short timeout is what fails fast and names itself, the race is the backstop for a promise that never settles at all. Race kept; it covers the case where the request's own timer is broken too. Third comment in three rounds encoding a mechanism the same commit changed.

Noted, so someone adding one later knows it would inherit a 50ms budget rather than reading the comment and looking elsewhere. The two installReceiverTaskResponseBypass guards read `this.receiverTasks` while the five gates around them read the advertisement. Installing the bypass mutates the Protocol's _requestHandlers map, so it is registration — same as the setRequestHandler it follows. Equivalent today; aligned so the convention is uniform rather than something the next reader has to re-derive per site. The genuinely-runtime `receiverTasks` reads are left.

The dead direction is the harmful one: if the tasks advertisement ever acquires a condition — the exact edit that produced the elicitation wedge — then advertised goes false while receiverTasks stays true, the bypass is not installed, and the handler still returns `{ task }` into the SDK's validating wrapper, which rejects it. That is the breakage the bypass exists to prevent, and before round 37 it could not happen because install and branch read the same field. All three now read tasksCapabilityAdvertised. `receiverTasks` is left where it belongs: assigned once, and driving the advertisement. Also noted that the wrapper's own check is redundant with its install guard and kept deliberately, since it must agree with the handler branch.

The crash path doesn't clear it, the connect() failure catch doesn't, and connect() never reset it — so a record created in one session survived into the next connect() on the same instance, and `tasks/list` is answered from that map. A new server would be told about a task it never created. Reachable in web (the only client with receiverTasks): a task-augmented sampling/createMessage arriving in the handshake window creates a record; if that connect then fails with a 401, App.tsx retries connect() on the same instance. Cleared at the top of connect() rather than only on the crash path — the auth-recovery retry means ending a session isn't the only way a new one begins, and starting clean covers every route in. disconnect() keeps its clear via the same extracted helper. Pre-existing — the crash path never cleared these — but the handshake window this PR opened is what lets a receiver task exist before connect resolves, and this was the one member left outside the invariant the PR documented.

Two of the other four have real symptoms on the same crash-then-reconnect path: - subscribedResources — the modern subscribeToResource early-returns on a uri already in the set, so after a reconnect the user's Subscribe click silently sends nothing to the new server while the UI keeps listing it. - cancelledTaskIds — a leftover id mislabels a *new* task sharing it as cancelled rather than failed, and server task ids are often short. taskInputAbortControllers leaked un-aborted controllers. modernLogLevel had the opposite asymmetry: disconnect() cleared it so it couldn't leak (#1629), but nothing restored it, so a reconnect after an explicit disconnect silently lost the user's configured level while a reconnect after a crash kept a mid-session override. It is now recomputed from serverSettings the way the constructor does, so both routes agree. clearReceiverTasks became resetSessionState, called from the same place. Tests cover the two symptomatic siblings and now assert receiver tasks through the `tasks/list` handler — what a server actually sees, and the symptom itself — which also removed the unjustified `as unknown as` the previous commit added. The remaining cast is justified in place, since cancelledTaskIds has no public reader.

On the one path that reconnects the *same* instance — auth recovery — the control then read Off while every modern request carried `_meta` logLevel "debug", the default. A tool whose job is showing what you send should not disagree with itself about what it sent. The control now re-seeds from the active server's settings exactly as setupClientForServer does, instead of blanking. Also from review: - Added the tests the restore never had, covering both halves: a mid-session override does not survive a reconnect, and a disconnect no longer drops the configured level (the #1629 half, and the actual behaviour change). - resetSessionState's doc claimed "every piece of state scoped to one connection", which invites assuming membership rather than checking it. Now states the rule: state a new session would misread; what only needs settling on the way out stays with the teardown paths. - Header: session-scoping paragraph moved below the outbound one to match test order, and it now names all five members rather than three.

The client and the Logs control agreed only because four sites happened to compute the same expression, and any drift reproduces exactly the symptom the previous commit fixed: the control reading one level while every modern request stamps another. Extracted resolveModernLogLevel into core/mcp/types.ts beside DEFAULT_MODERN_LOG_LEVEL; all four call sites use it, with the web mapping undefined→null at its own boundary (display, not a second derivation). Also from review: - disconnect()'s comment still credited itself with preventing the #1629 leak, which resetSessionState now prevents. It says what the line does now — read "not opted in" while disconnected — and notes the web control deliberately shows the configured level in that window. - resetSessionState's doc claimed an un-aborted taskInputAbortControllers entry "leaks a paused poll loop". Both registration sites release in a finally, so nothing leaks permanently; the abort closes the window between a crash and the unwind. Softened, and it now has the test it lacked — the only member of the five without one. - Noted in App.tsx that the re-seed depends on activeServerIdRef still holding the outgoing id (it syncs in a passive effect), so an eager clear would silently drop it to the default.

No symptom today only because the UI mirror resets itself independently, in another file — which is the arrangement this PR has spent its rounds removing. Clearing it here also announces the reset; that set's every other mutation dispatches. Also from review: - The web re-seed treated "no server found" as the default level rather than Off, because resolveModernLogLevel returns the default for absent *settings*. Reachable via a second disconnect after a crash, and via removing the active server. Now distinguishes the two. - Converged the two injectRequest copies: withTimeout takes an optional onTimeout, so both drop their waiter on the timeout path. The newer copy had lost exactly the cleanup that was round 33's reason for leaving the original alone.

My round-43 fix traded one wrong branch for another: it read `?.settings`, which is undefined both when no server matched *and* when the server has no settings node — and the second is the common case (a hand-written mcp.json entry never opened in Server Settings). Those servers showed Debug while connected and Off after disconnect, which is exactly the client/UI disagreement rounds 41-42 removed, with no modernLogLevelChange event to reconcile it. Now branches on the server. Worth noting no test would have caught it: App.tsx is a documented exclusion from the coverage gate. Also from review: - resetSessionState cleared subscribedResources without announcing it, two lines below a comment arguing that every other mutation of that set dispatches. And it took two statements of a six-statement cluster disconnect() clears together — leaving modernReconnectAttempts (a new session's first drop would back off as if it were the old one's nth), modernListenGeneration (the bump that makes an in-flight re-listen bail), and a stale modernSubscription. One resetSubscriptionStream helper now serves both, announcing both axes; disconnect() keeps only the live stream's best-effort close. That also removed the file's one assignment to modernStreamState that bypassed its setter. - The stream-state test pinned the value, not the dispatch — the half the UI actually tracks. Now asserts both; verified against a bare field assignment. - onModernSubscriptionClosed's comment claimed the disconnect reset always clears the set; on a crash it doesn't until the next connect. Says so.

Dead text where it sat, and the most load-bearing comment in the batch. Moved, not reworded. That is round 32's finding in production code, from the same cause: inserting anything between a doc block and its method is a move that needs checking, prose or code. Also from review: - resetSubscriptionStream announced the cleared set before updating the stream state derived from it, so a listener in between saw an empty set with an `active` stream — the combination the helper exists to prevent, exposed by its own dispatches. Both fields move first, then both are announced. The onModernSubscriptionClosed comment now says that window is never observable, which is newly true. - The test header called the log level "cleared"; it is re-seeded, which is the #1629 half of the test twenty lines below. Says "reset", with the distinction spelled out, and the paragraph reflowed in one pass. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_011TrCvpunxToe7qnppk6zwr * fix(core): close the listen stream the connect-path reset drops (#1797) Round-46 review: resetSubscriptionStream's doc claimed disconnect() is the only caller with a stream worth closing, and the helper did a bare `modernSubscription = null`. Not guaranteed on the connect path — an `onerror` without an `onclose` leaves the transport up, connect() reuses it, and the reset then drops the last reference to a stream still open on the server. Nothing can close it afterwards: the `closed` handler bails on the bumped generation, and `closed` never resolves for a live stream. Before the extraction the surviving reference was eventually closed by refreshModernSubscription as `previous`, so this was newly unclosable. The helper now closes it itself, best-effort, after the dispatches so the round-45 ordering is unaffected; disconnect() drops its two hand-rolled lines. Also from review: - The session test pinned the subscription set's value but not its dispatch — the half the UI tracks, and the gap round 43 closed for the stream axis one line away. Both now asserted; verified load-bearing. - resetSessionState's doc said disconnect() "clears all of this", which is true by duplication for two of the five members; it now says a sixth has to be added in both places. And "the teardown paths" handle the in-flight tool call only on the disconnect route — on a crash it is callTool's own finally. Named. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_011TrCvpunxToe7qnppk6zwr * review: round-47 — fix the doc's count, catch the closed-promise chain (#1797) - resetSessionState's doc said "two members through the same helpers, the other two hand-rolled" for a body with five. It is two and three — and the member the enumeration dropped is the one that is *paired* rather than duplicated: modernLogLevel is re-derived here and blanked in disconnect(), deliberately. Both corrected. - `subscription.closed.then(...)` had no rejection handler, unlike every other promise around that stream. Newly reachable: before the last commit a connect-path reset dropped the reference with `closed` permanently pending, so the chain never settled at all; closing the stream is what makes it settle. Added, with the Node-terminates reasoning the file already applies to payloadPromise. - The listen-stream test exercised transport reuse without asserting it — the half that makes "still open on the server" true. Counts factory calls now, so the premise fails loudly if a future change recreates the transport rather than silently ceasing to apply. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_011TrCvpunxToe7qnppk6zwr * review: round-48 — scope the catch, guard the close, index the test (#1797) - The .catch comment claimed the connect-path close made a *rejecting* `closed` reachable. It doesn't: closing resolves it. What that close newly reaches is the handler running at all, where the reference used to be dropped with `closed` pending forever. And chaining after `.then` also swallowed handler throws — silently abandoning a re-listen on the path whose job is recovering a dropped stream. Now the second argument to `.then`, scoped to the rejection, with the comment saying which half is which. - `closing?.close()` reaches into third-party code from `disconnect()`'s straight-line teardown, none of which is inside a `try` — a synchronous throw would skip the raw-wire rejects, the task aborts, the receiver-task clear and nine dispatches, silently, since most callers catch a disconnect(). Best-effort now against both failure modes. - Header indexes the listen-stream test: same category, but a release obligation rather than a misread one. - Its comment described the generation guard, which the stub can't exercise; marked as production behaviour. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_011TrCvpunxToe7qnppk6zwr * review: round-49 — pin the best-effort close, unorphan the doc (#1797) Round 48 made `resetSubscriptionStream`'s close best-effort against both a rejected promise and a synchronous throw, but nothing exercised either arm: both `modernSubscription` stubs in the tree resolve. On the `disconnect()` path an escaping failure would silently skip the raw-wire rejects, the paused task-input aborts, the tool-call abort and `clearReceiverTasks()` — the findings rounds 13 and 30 closed, re-opened at once with a green suite. Two table-driven cases now seed a `close()` that throws and one that rejects, and assert teardown continued past it. Also: the `.then` comment gave opposite verdicts on one mechanism (an unhandled rejection is named unacceptable, then chosen for a handler throw) — reworded to say the handler cannot throw today and why the shape is defensive; and `refreshModernSubscription`'s doc block, orphaned two methods up since before this branch, moved onto the method it describes. Closes #1797 * review: round-50 — sweep the queues start-clean, unify the close (#1797) `resetSessionState`'s doc excluded the peer-request queues and the raw-wire map because "the teardown paths handle them" — true of the paths that run. An `onerror` without an `onclose` runs none of them: it flips status to "error" and leaves `baseTransport` cached, so a `connect()` on the same instance reuses a live transport. That is the route the round-46 stream close was built on, and it strands these two the same way — the web pending-request modal is derived from the queue length with no status gate, so it outlives the session, and answering it writes a response for the old request id onto the new connection. Both are now swept start-clean beside the reset (both helpers are idempotent, so the routes that already ran them are unaffected), the end-clean clears stay put for the `disconnect`-event consumer, and both docs say which is which. Also folds the three subscription `close()` sites onto one `closeSubscriptionBestEffort` helper, so all three absorb a synchronous throw as well as a rejection — at `refreshModernSubscription`'s first site the reference is already dropped, so a throw there both leaks a live stream and aborts the refresh before its replacement is opened. Closes #1797 * review: round-51 — pin the sweep's ordering, name the category (#1797) The connect-start sweep must sit after `resetSessionState()`, and the two calls read as independent. Cancelling a task-augmented peer request settles it synchronously into the record callback, which ends in `upsertReceiverTask` — a no-op only because `clearReceiverTasks()` just emptied the map. Hoisted, it would emit a `notifications/tasks/status` for the outgoing session's task onto the transport the connect is about to reuse. Stated at the call and pinned by a test (which fails on the hoist). Adding that third caller also made five docs stale, all describing the old set by count or as "teardown" — the class round 23 diagnosed. All five now name the category: every route out, plus the top of `connect()` as a backstop for the one route in that settles nothing. And the site where round 50's fold actually changed behaviour — `refreshModernSubscription`'s first close, where the reference is already dropped and a `.catch()` never caught a synchronous throw — is now tested from the public surface (a re-list over a poisoned stream), table-driven over both arms. Verified to fail on the pre-fold form. Closes #1797 * review: round-52 — say what the sweep prevents, scope the close doc (#1797) The sweep's comment named as its harm the exact write the sweep performs: on this route the SDK's transport is still live, so cancelling a queued peer request emits a response for the old id immediately — which is right, and is the settle-don't-discard rule, at the best available moment. As written it read as an argument against emitting the frame, inviting the clear-without- settling regression rounds 24–25 removed. It now names the real hazard: a *user*-authored answer landing arbitrarily later, past the re-handshake. `closeSubscriptionBestEffort`'s "at each site" held at two of three — the superseded-generation discard stored nothing and has nothing following it, so its escaping failure would only reject an already-superseded `subscribeToResource`. Scoped, still wrapped. Also moves the `disconnect()`-side close pair next to its `connect()`-side twin, and states which axis the file's ordering follows, since route and category both describe it and cut differently. Closes #1797 * review: round-53 — give each close site its real harm, pin it (#1797) The doc grouped `resetSubscriptionStream`'s close with the "takes the caller's remaining work with it" sites. It can't: the call is `void`-ed onto an `async` helper, so even a synchronous `close()` throw becomes a dropped rejection — `disconnect()`'s teardown runs regardless. The harm there is an *unhandled* rejection, which this PR already established (the payloadPromise fix) is the process-fatal class in Node — so the one site with the severe failure mode was documented as having the mild one. Each site now carries its own consequence, and the local comment no longer gives two reasons that cancel each other. The test had the same gap: both its assertions hold with the helper's try/catch deleted. It now also asserts no unhandled rejection fired, which does fail without the guard (verified on both arms); the teardown assertions stay, since they still catch unwrapping the call to a bare `close()`. Also names the two back-references the round-52 move left positional, and softens the "on the wire until dropCachedTransport()" claim — that drop is conditional and never runs on stdio. Closes #1797 * review: round-54 — the mildest site isn't mild from every caller (#1797) `refreshModernSubscription` has three callers, and the superseded-generation discard's failure reaches all of them. From `unsubscribeFromResource` — which deliberately keeps the removal when a re-listen fails — it surfaces "Failed to unsubscribe" for an unsubscribe that actually stuck, which is worse than the consequence the doc assigned to the site it called mildest. The re-listen bullet had the mirror gap: on the reconnect caller the escape is absorbed into the backoff run, not a set left with no stream. Both now name their callers, and the generation-bump claim is softened to what it proves (a newer refresh *started*). Test: the `unhandledRejection` listener is process-wide, so the assertion now filters to this fixture's own reason rather than failing on a rejection some other test left pending; and it is registered inside the `try` whose `finally` removes it, so a throw in the setup can't leak it into the rest of the file. Re-verified the filtered form still fails on both arms with the helper's try/catch removed. Closes #1797 * fix(core): don't roll back a subscribe a newer refresh superseded (#1797) `subscribeToResource`'s rollback assumes what its comment says — that the server filter is unchanged — which is exactly what supersession falsifies. The newer refresh built its filter from the set *including* this URI, so on success the server honors it; rolling back leaves the set missing a URI the live stream carries (the UI showing it unsubscribed while its resources/updated keep arriving) and, if it was the only one, an empty set with an active stream — the combination `resetSubscriptionStream` exists to prevent, reached from the other end. Reachable without any close() failure: a rejecting `listen()` propagates the same way, which a user subscribing while the reconnect timer re-lists — i.e. exactly when the server is flaky — can produce. The rollback is now gated on the generation not having advanced past this call's own bump; the error still reaches the caller either way. Test drives two overlapping subscribes with the first `listen()` rejecting, and fails without the gate. The doc bullet that called this the mild site is corrected with it: both user-initiated callers report a failure that did not happen, in mirrored ways. Also gives the two close-failure arms distinct reasons so the unhandled-rejection filter can exclude the sibling arm as well as a foreign rejection. Closes #1797 * fix(core): reconcile the stream badge when a re-listen this call owned fails The supersession gate left the both-fail case stuck: two overlapping subscribes whose listens both reject leave the superseded URI in the set (its rollback correctly skipped) while the state keeps the optimistic "connecting" — no stream, no reconnect armed (neither onModernSubscriptionClosed nor onModernReconnectFailed ran), so the badge never changes and no resources/updated ever arrive. That is the caveat this file already wrote down for the neighbouring case — the bump proves a newer refresh *started* — applied to the gate itself. Fixed in the branch that knows the answer: the call that still owns the re-listen reconciles the state instead of only handling an emptied set, reusing the "ended" badge onModernSubscriptionClosed already reports for "stream gone, URIs still subscribed". unsubscribeFromResource gets the same treatment — it rolls nothing back by design, but its failed re-listen left the badge reading Listening over no stream. Also: the gate's comment named one of the two things that bump the generation (resetSubscriptionStream also does, from disconnect and the start-clean reset) and cross-referenced the wrong invariant; both corrected, and `<=` tightened to `===`, which is what the monotonic synchronous bump actually guarantees. Closes #1797 * fix(core): order the subscription writes, retry instead of stranding Two sites emptied the subscription set and announced it before the stream state caught up — the last-URI rollback in subscribeToResource's catch, and (pre-existing) the ordinary last-URI unsubscribe, which dispatches a round-trip before the re-listen sets INACTIVE. Both exposed an empty set with an active stream: the pair resetSubscriptionStream orders its own writes to prevent, and which three comments in this branch now cite. State before the announce at both, asserted from the consumer's side. And the reconcile added last round settled for an honest but dead badge: it was the only route to "stream gone, URIs live" that had made no attempt at all, over subscriptions the server may never have honored, recoverable only by an Unsubscribe/Subscribe toggle (a fresh Subscribe early-returns). It now hands them to the reconnect machinery, which already fits — base delay after a user-initiated refresh, bails on a terminal status or an emptied set, and lands on the same "ended" badge past the cap. That also removes the provably-dead null check the reconcile carried. Closes #1797 --------- Co-authored-by: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-07-27 11:32:23 -04:00
Cliff Hall	cea22d86b8	feat(web): enforce localhost-only binding; expand loopback origin allow-list (#1796) ... Closes #1795. Enforce localhost-only binding in code (the "never 0.0.0.0" rule was only a spec note): refuse an all-interfaces HOST — across every spelling the OS binds as the wildcard (inet_aton decimal/octal/hex, IPv6, IPv4-mapped, zone-scoped, IDNA/Unicode) — unless DANGEROUSLY_BIND_ALL_INTERFACES=true (Docker's sanctioned opt-in). Fixes the reported stdio-connect 403 by expanding the default loopback origin allow-list to all three interchangeable forms. Hardening surfaced across an extended review: closes an IDNA/fullwidth wildcard bypass, a blank-ALLOWED_ORIGINS fail-open, and the CLI/TUI OAuth-callback wildcard bind (loopback-only now, RFC 8252); canonicalizes the origin allow-list the way a browser does; derives frame-ancestors from the real embedder list (IPv6-literal exclusion verified in headless Chromium); strictPort on all three bind points; and preserves the CLI exit-code map + JSON envelope through the mcp-inspector --cli launcher path.

Config - Add `ServerProtocolEra` ("legacy" | "auto" | "modern"), `DEFAULT_PROTOCOL_ERA` (legacy, per the SDK's don't-auto-probe guidance), `MODERN_PROTOCOL_VERSION`, and `eraToVersionNegotiation()` in core/mcp/types.ts. - Persist `protocolEra` on `StoredMCPServer` / `InspectorServerSettings`, round-tripping through serverList.ts (omitting the default on disk) and the `/api/servers` read + write validators. InspectorClient / state - Thread `versionNegotiation` through `InspectorClientOptions` (default legacy), replacing the hardcoded pin. After connect, read `getProtocolEra()` / `getDiscoverResult()` / `getNegotiatedProtocolVersion()`, expose them via getters, dispatch `protocolEraChange` / `discoverResultChange`, and clear on disconnect. `useInspectorClient` surfaces `protocolEra` / `discoverResult`.

cliffhall	19a6df7ad3	SDK v2 migration (behavior-neutral, versionNegotiation: 'legacy') (#1624) ... Migrate all three clients + core + test-servers from @modelcontextprotocol/sdk@1.29 to SDK v2 (2.0.0-beta.4), keeping behavior identical against legacy (2025-11-25) servers. Foundation for the SDK V2 + New Spec stack. Packages - Split @modelcontextprotocol/sdk -> @modelcontextprotocol/client (Client, transports, OAuth, error taxonomy, protocol types) + core (Zod schemas); stdio -> client/stdio, Ajv -> client/validators/ajv. Test-servers -> @modelcontextprotocol/server (+ server-legacy/sse). Deterministic import rewrite (schemas -> core, everything else -> client); the codemod misroutes client code to /server so it was not used for path routing. - new Client(..., { versionNegotiation: { mode: 'legacy' } }) — nothing 2026-era goes on the wire. Runtime (core/mcp/inspectorClient.ts) - Error taxonomy: McpError -> ProtocolError, ErrorCode -> ProtocolErrorCode; RequestTimeout -> SdkError/SdkErrorCode. - Handlers take method strings; task methods (tasks/*, notifications/tasks/*) use the 3-arg custom form (excluded from v2's spec-method set). - Legacy tasks kept working (per project requirement): requestor tasks re- implemented over raw client.request + explicit deprecated schemas; experimental.tasks.callToolStream replaced by a local pollTaskToolCall async generator (with _progressHandlers revival so task-execution progress still reaches the caller). Receiver (server-initiated) tasks: the v2 Client validates a sampling/elicit handler result and rejects the legacy { task } response with -32602 — installReceiverTaskResponseBypass swaps the wrapped entry in the private _requestHandlers map for the task-augmented branch so { task } reaches the wire (fixes server-initiated sampling-via-task). - Pagination: list verbs use raw client.request({method}, List*ResultSchema) for single-page behavior (v2's client.listX() auto-aggregate all pages). Web / auth / apps - Rename local JsonSchemaType -> InspectorFormSchema + add toFormSchema() structural narrowing at the SDK-schema -> form boundary. - ext-apps still peers on SDK v1: one compat boundary with documented casts (remove when ext-apps#702 lands a v2 peer). - OAuth provider saveClientInformation reconciled with v2's OAuthClientInformationContext; InvalidClientMetadataError re-homed as a local class (server-legacy/auth is not browser-safe). - vitest.shared.mts dedupes @modelcontextprotocol/client+core to one copy so vi.mock intercepts the SUT's import. Accepted v2 behavior changes (per #1624 / spec §9.2): unknown-tool call rejects with -32602; cancellation is stream-abort (no guaranteed notifications/cancelled frame); output-schema strictness restored via the Inspector's own Ajv check on the default path. npm run ci green: validate (web 3087 / cli 212 / tui 274 / launcher 5), coverage (>=90 per-file, all clients), smoke (launcher/cli/web), storybook (410).

cliffhall	59f3bd92a4	cli: address #1673 review — refresh fallback, 0600 write, distinct code ... - Refresh failure now falls back to injecting a still-present stored access token instead of hard-exiting 3, so a transient auth-server hiccup doesn't regress a previously-working invocation (review #1). Only a failure with no access token to fall back on surfaces as exit 3. - Persist rotated tokens via the shared writeStoreFile (0o600 + mkdir -p) instead of a raw writeFile, so the secrets file keeps owner-only perms identical to the web backend (review #2). - Missing clientInformation now throws the distinct no_client_information envelope code rather than reusing no_stored_token (review #5a). - Docs: --wait-for-auth no longer claims parity with --use-stored-auth (it injects the freshly-landed token without refreshing); noted the always-refresh rotation/concurrency caveat (review #3, #4). - Tests: discovery-returns-undefined metadata path, no_client_information code, and an e2e refresh-failure → access-token fallback.

cliffhall	cdf124106e	cli: stored-auth injection honors refresh_token, not just access_token (#1665) ... Closes #1665 `--use-stored-auth` previously injected the stored access token blindly, so an expired token failed even with a valid refresh_token on disk. Now, when a `refresh_token` is stored, the CLI runs the OAuth refresh grant and injects the fresh access token, persisting the rotation. - New exported `refreshStoredAuthToken(serverUrl, statePath, deps?)`: reuses the SDK's `refreshAuthorization` (not a hand-rolled token request) with the stored `clientInformation` + `serverMetadata` (discovered via core `getAuthorizationServerUrl` + SDK `discoverAuthorizationServerMetadata` when the metadata wasn't persisted). Rotated tokens are written back through `serializeOAuthPersistBlob` under the same `{servers,idpSessions}` key, so web and CLI stay consistent. Missing refresh_token/clientInformation or a failed grant throw `CliExitCodeError(AUTH_REQUIRED)` with a clear message + envelope code (`no_stored_token` / `refresh_failed`). - `--use-stored-auth` prefers refresh when a refresh_token is present (covers both absent and expired access tokens — the stored blob has no expiry, so the refresh token is the durable credential); falls back to injecting the stored access token otherwise (unchanged). - `deps` are injectable so the refresh/discovery are unit-tested without a live token endpoint; an e2e test drives the real SDK path against a mock token endpoint and asserts the refreshed token is injected + the rotation persisted. - CLI README updated (removed the "blind injection" caveat). CLI coverage gate green (cli.ts 100/92/100/100). Part of the #1579 decomposition (Wave 4, CLI lane).

cliffhall	93f3fb64f2	cli: reconcile --print-handoff deep-link with #1576 canonical format (#1666) ... Closes #1666 #1575 shipped `--print-handoff` with an interim deep-link shape (hardcoded `transport: "http"`, marked `TODO(#1576)`). Now that #1576 owns the canonical `?serverUrl&transport&autoConnect` format, `--print-handoff` emits exactly it: - New `deepLinkTransport(serverUrl, transport)` helper derives `http`|`sse` from the resolved server — explicit `--transport` wins, else auto-detect from the URL path (`/sse` → sse), else default `http`. Unlike the core resolver it defaults instead of throwing (the handoff is best-effort; the web parser defaults an unknown transport to http too). - `buildHandoff` takes the transport, emits the normalized serverUrl + derived transport in the query, and keeps `autoConnect=<token>` (which #1576 adopted as the canonical CSRF gate, so the interim guess was already correct). - Removed the `TODO(#1576)` marker; updated the doc comment + CLI README. Tests: handoff emits `transport=http` for `/mcp`, `transport=sse` for `/sse` and for explicit `--transport sse`; `deepLinkTransport` unit tests cover the explicit/auto/default/stdio/unparseable branches. CLI coverage gate green (cli.ts 100/92.8/100/100). Part of the #1579 decomposition (Wave 4).

Cliff Hall	a029e42a19	cli: Wave 3 — programmatic review path (rollup of #1573–#1575) (#1655) ... * feat(cli): programmatic ergonomics — initialize, tool-args-json, connect-timeout, env-var fixes Adds the #1573 programmatic-ergonomics surface to the CLI, re-implemented informed by PR #1510 and adapted to the v2/main OAuth-wired cli.ts: - `--method initialize` — connect-only probe emitting `{serverInfo, protocolVersion, capabilities, instructions}`. - `--tool-args-json '{"k":"v"}'` — tool args passed verbatim as JSON (no key=value coercion); mutually exclusive with `--tool-arg`, with clear errors for combined use, malformed JSON, and non-object values. - `--connect-timeout <ms>` — default 15000 for ad-hoc `--server-url`/target runs, file-level timeout otherwise; `0` disables. Backed by the exported `withConnectTimeout()` helper. - MCP_CATALOG_PATH is ignored when an ad-hoc target is given, so a shell that exports it can still run one-off ad-hoc invocations. - MCP_STORAGE_DIR is honored by core `getStateFilePath` (`<dir>/oauth.json`), below the per-file MCP_INSPECTOR_OAUTH_STATE_PATH override. Tests: new programmatic-ergonomics.test.ts (CLI, in-process runCli + direct withConnectTimeout unit tests) and getStateFilePath resolution cases in the web storage integration suite. Per-file coverage gate stays ≥90. README: documents the new flags and env-var semantics. Closes #1573 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01BrihGWcrM9JGRyu41nzZYw * feat(cli): --app-info probe + --format json envelope Adds the #1574 app-probing and machine-readable output surface, re-implemented informed by PR #1510 and adapted to the v2/main OAuth-wired cli.ts. - `--method tools/call --tool-name <t> --app-info` — prints one JSON line describing the tool's app posture (hasApp, resourceUri, csp, permissions, domain, …) WITHOUT invoking the tool; exit 0 when it has an app, 2 (no_app) when it doesn't. A missing tool exits 5 (tool_not_found) — distinct from the no-app exit so a typo isn't mistaken for "no app". - `--method tools/list --app-info` — one NDJSON line per tool over a single connection (`| jq -c 'select(.hasApp)'`). - `--format json` — a single stdout envelope (`{result}` plus `{appInfo}` as a sibling key for App tools), no banner, so any method pipes into jq. - A tools/call returning isError:true now exits 5 (tool_is_error) after printing its payload, so && chains stop on a failed call. Implementation: `collectAppInfo()` (core `extractAppInfo` + a tolerated resource read that reports `resourceError`), an NDJSON loop in tools/list, and a single `emitResult()` that owns format + exit-code handling. `runMethod` now returns a `MethodOutcome` discriminated union so the NDJSON path can signal "already emitted". Tests: app-info.test.ts (exit-0/2/5 + NDJSON + no-invoke), format-json.test.ts (envelope shapes + bad --format), emit-result.test.ts (direct unit coverage of the isError→exit-5 and resourceError branches via exported emitResult/ collectAppInfo). Updated the tools.test "nonexistent tool" case to the new exit-5 tool_not_found contract. Per-file coverage ≥90 on all four dimensions (cli.ts 100% stmts/funcs/lines). README documents the flags, NDJSON shape, and exit semantics.

Adaptations vs. the reference: - State-path resolution reuses core `getStateFilePath()` (the MCP_INSPECTOR_OAUTH_STATE_PATH → <MCP_STORAGE_DIR>/oauth.json → default precedence added in #1573) instead of a CLI-local resolver. - The state file is read through the shared isomorphic `parseOAuthPersistBlob`, so both the plain `{servers,idpSessions}` layout the web backend writes and the legacy `{state,version}` envelope are accepted. - `parseArgs` now returns a ParseResult union so the short-circuit modes return without a server connection. Blind injection: the token is passed as-is; a stale one surfaces as HTTP 401 → exit 3. Documented in the README along with all four flags, the state-path precedence, and a follow-up note that --print-handoff's deepLink shape is interim pending #1576's canonical handoff format. Tests: stored-auth.test.ts drives injection, --header coexistence, missing --server-url, no-token exit-3, URL-normalisation matching, MCP_STORAGE_DIR resolution, listing, handoff (+note), wait-for-auth polling/timeout, and normalizeServerUrl units — all against a real in-process HTTP test server.

Narrow the comment to state it is OAuth-backend-only (client.json/mcp.json still resolve from getDefaultStorageDir → HOME) and record why the resolution lives here rather than in getDefaultStorageDir (the default-path constant is evaluated at module load, so a runtime-set MCP_STORAGE_DIR — as the CLI stored-auth / --wait-for-auth flows set it — must be read at call time).

This makes `tools/list --app-info` per-tool tolerant — one bad tool no longer aborts the whole NDJSON listing with a generic exit-1. Guarding inside collectAppInfo (vs. a loop-local try/catch) keeps the branch unit-testable; added an emit-result.test.ts case for the malformed-URI path. - Documented that `tools/list --app-info` always emits NDJSON regardless of `--format` (the per-tool list shape is fixed; --format json only reshapes the single-result paths) — in both the code comment and the README. - Removed the now-unused `expectJsonError` helper (its only caller moved to the exit-5 tool_not_found contract).

cliffhall	7815548300	refactor(version): single-source the version from the root package.json ... The Inspector ships as one package with one version, but four client package.jsons each carried their own `version` and were read at runtime (cli.ts, tui App.tsx), and core hardcoded a third, stale value (0.20.0) that the TUI and web actually reported to servers. Consolidate onto the root package.json as the single source of truth. - Add core/node/version.ts: shared, Node-only readInspectorVersion() that walks up to the root package.json (always shipped in the tarball). 100% covered by a new integration test. - CLI and TUI read the version via the shared reader instead of their own manifest; TUI now also passes a real clientIdentity (was falling through to the stale core default). - Drop the `version` field from all four client package.jsons; the root keeps the only version. TUI header name/description become local display constants. - core default client identity: replace the stale 0.20.0 hardcode with a neutral 0.0.0 placeholder (real clients pass clientIdentity; web will source its version from GET /api/config, see #1639). - Stop shipping clients/cli/package.json and clients/tui/package.json (no longer read at runtime) — supersedes the earlier "ship them" fix; update pack:verify and the root README packaging invariants accordingly. - Add core/node/** to the web coverage include so the new module is gated. - Add the shared-code architecture diagram to the root README.

Additionally, imported `ensureCimdClientRegistration` in the OAuthManager to streamline client registration during the authentication process. * Guided-auth removal, OAuth smoke testing, and TUI/CLI support * Added CLI OAuth runner flags tests * Added clarifying comment on port 0 binding * README notes on TUI oauth callback port, prettier fixes for CLI tests * CIMD validation uses inline like EMA IdP * Fixed TUI test failures from merge * test: bring 5 OAuth files over the 90 per-file coverage gate The guided-auth-removal work added/touched several files that fell below the repo's >=90 per-file coverage gate (npm run coverage).

CI does not run the coverage gate, so this accumulated. Add tests to bring every failing file above the gate and push branch coverage well past 70 across the board, then raise the per-file branches threshold 50 -> 70 in clients/web/vite.config.ts. - EMA core (emaFlow, resourceContext, jwt, wire): 50-88% -> 86-100% branch - EMA OIDC/transport (idpOidc, tokenEndpoint, transportProvider): -> 97-100% - oauthManager / discovery: 73-83% -> 88-92% - ClientSettingsModal/Form, ConnectionInfoContent: 0-88% -> 96-100% - useClientSettingsDraft / useEmaIdpLoginState hooks: 20% -> 100% - TaskStatusBadge / SortableServerCard outliers: 50% -> 100% Coverable branches reached by mocking useComputedColorScheme (dark theme), dnd-kit useSortable (isDragging), and fetch/OIDC paths. Remaining sub-100 branches are genuinely-unreachable defensive guards or happy-dom-inherent (portal / useMediaQuery / typeof window) and documented in test comments. No source files changed. Global web branch coverage 88.73% -> 90.63%. AGENTS.md updated; cli/tui/launcher stay at 50 (out of scope). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * test: raise per-file coverage gate to 90/90/90/90 across all clients Follows the #1271 web branch-coverage audit (50 -> 70) by raising the whole per-file gate to >=90 on all four dimensions — lines, statements, functions, branches — for web, cli, tui, and launcher (core/ is measured under the web suite). A codebase-wide audit added real tests for every outlier and brought global coverage up across the board. Config: all four vitest/vite coverage configs set to 90/90/90/90. Two pure-type modules (core/mcp/import/types.ts, clients/web/server/ types.ts) added to the web coverage exclude list, matching the existing type-only exclusions. Tests: ~50 test files extended/created across core (auth, ema, mcp, remote, state, storage, react), web components/screens/server, and the cli/tui clients. Highlights: full EMA OAuth flow + transport coverage, inspectorClient/remote server backfill, every Mantine control's handler branches, and the cli unsupported-method / argv-fallback paths. Genuinely-unreachable branches are annotated at the source with justified `/* v8 ignore -- <reason> */` comments rather than lowering the gate: happy-dom-inherent paths (Mantine portal, useMediaQuery, typeof window SSR guards), React StrictMode effect replay, and provably-dead defensive guards (?? fallbacks the types make impossible, Select.onChange values outside the allowed list). No runtime logic changed; the only structural edits are two behavior-preserving refactors (ResourceTemplatePanel hoists the field value to a local so the ignore applies in JSX; ToolsScreen swaps a ternary for an if) and prettier line-wrapping. Also fixed a flaky real-timer debounce assertion in PromptArgumentsForm (asserted an exact sibling-typing interleaving that raced the 300ms debounce; now asserts the load-bearing fact — a non-empty fire-time sibling capture). AGENTS.md updated to describe the uniform 90 gate and the v8-ignore policy. All four client coverage gates, root validate, storybook (370), and smoke pass. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * test(web): make connect-crash SSE reader stop on the terminal event `readSseEvents` looped until the server closed the stream (`done`). The server closes the events stream immediately after writing the terminal `transport_error`, but under the heavy parallel scheduler pressure of a full `coverage` run (v8 instrumentation across all workers) that close can lag far enough behind the event to trip the 30s test timeout — a hang, not a wrong result. This made the test intermittently fail under `npm run coverage` (it passed in isolation and under CI's lighter `test:integration`). Stop reading as soon as the terminal `transport_error` event arrives (cancelling the reader) instead of waiting only for `done`. That event is always the last one the session queue emits, so nothing is lost, and the test no longer depends on stream-close timing. The `done` break is kept for any stream that closes first. Verified green across two consecutive full `npm run test:coverage` runs (3094 tests) where it previously hung, plus isolation (~0.5s).

Cliff Hall	388ea5a7bd	test(cli,tui): add in-process source coverage gates (#1484) (#1502) ... * 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. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * 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). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * chore: compose root test:coverage from per-client scripts Replace the brittle inline cd-chain with a composition of the existing test:cli / test:tui scripts plus a new matching test:web. Behavior is unchanged (web → cli → tui coverage gates) but there's a single source of truth for each client's coverage invocation.

Cliff Hall	e72d4307f3	feat(cli): lift config-file headers/timeouts/OAuth into serverSettings (#1482) (#1500) ... * feat(cli): lift config-file headers/timeouts/OAuth into serverSettings (#1482) The CLI resolved file-sourced servers via resolveServerConfigs(), which returns bare MCPServerConfig and dropped disk-level headers, timeouts, and OAuth — CLI connections from a --catalog/--config file silently ignored them. The TUI already lifted these via mcpConfigToServerEntries(). Extract the TUI's catalog/config -> per-server-settings resolution into a shared core module (core/mcp/node/servers.ts: loadServerEntries + selectServerEntry) and route both CLI and TUI through it, so the two share one file->settings path. --header still overrides the file's headers for the run while preserving the file's timeouts/OAuth. - core: add loadServerEntries/selectServerEntry/headersToServerSettings - tui: tui-servers.ts re-exports the shared core helpers (no logic dup) - cli: resolve via loadServerEntries + selectServerEntry; drop the CLI-only conflict check and bare-config path - tests: core servers.test.ts (settings lifting, header merge/override, stdio overrides, seed/error/conflict, selection); CLI integration tests asserting a config header is sent over HTTP and --header overrides it - docs: CLI README note on file settings being applied Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * refactor(core): address #1500 review — dedup overrides, drop dead wrapper, clearer error, spec refresh - Remove the now-unused resolveLaunchServerConfigs() wrapper (both CLI and TUI route through loadServerEntries now); migrate its default-catalog launch tests to compose withDefaultCatalogPath + resolveServerConfigs. - Deduplicate applyStdioOverrides against config.ts applyOverrides: export the latter (now trims cwd) and reuse it in servers.ts. - selectServerEntry's unknown-name error is source-agnostic ("not found" not "not found in config file") since entries may be a single ad-hoc default, where "config file" would mislead. - Refresh specification/ docs (v2_cli_tui_launcher.md, v2_catalog_launch_config.md): CLI/TUI resolution now via loadServerEntries/selectServerEntry; mark gap G1 resolved (#1482); withDefaultConfigPath → withDefaultCatalogPath. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * test(cli): extend smoke:cli to cover #1482 lift→serverSettings Adds end-to-end smoke coverage for the config-file headers/timeouts/OAuth lift introduced in #1482: - unknown --server now errors source-agnostically ("not found") - multi-server catalog selection via --server (and the omit-it error) - --header merge does not break the stdio connect path - HTTP transport: a config-file `headers` object is lifted onto the wire, and a CLI --header overrides it (verified against an in-process test server's recorded requests via a non-blocking spawn) Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-20 11:33:21 -04:00
Cliff Hall	73b651ff21	feat(cli,tui): normalize --catalog / --config with web; update --help (#1347) (#1499) ... * 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. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * 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). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * refactor(cli): trim --config to match --catalog and the TUI (#1499 review) Cosmetic uniformity follow-up from the re-review: configPath now uses `options.config?.trim() || undefined`, matching the catalog slot above it and the TUI. Behavior is unchanged (resolveServerSource/serverSourceConflict already trim downstream).

Bob Dickinson	2488ca5e38	feat: port CLI, TUI, and launcher from v1.5 into v2 (#1452) ... Ports the CLI, TUI, and launcher from v1.5 into v2 behind a single `mcp-inspector` entrypoint (launcher → web/cli/tui). Includes the `mcp-inspector --web --dev` launcher fix (Vite alias resolution + prod-server double-start), the root `postinstall` install cascade with simplified CI, and spec/AGENTS docs (no-workspaces rationale, Development setup).
