Sam Morrow	5d91d4acd0	fix(core): mirror SEP-2243 x-mcp-header args to Mcp-Param-* on tools/call (#1847) ... * fix(core): mirror SEP-2243 x-mcp-header args to Mcp-Param-* on tools/call (#1846) A strict modern (2026-07-28) HTTP server (e.g. the GitHub MCP Server) rejects a tools/call whose argument carries an `x-mcp-header` annotation when the matching `Mcp-Param-*` request header is missing (-32020 "header mismatch"). The Inspector never sent that header. The SDK only mirrors inside `client.callTool()` (and skips it entirely in a browser environment), but the Inspector routes tools/call through `client.request()` for manual MRTR driving (#1704), so the SDK never mirrors for us — on any transport. On top of that, the remote (web) transport dropped per-request headers before they reached the backend's upstream fetch. - core/json/xMcpHeader.ts: port the SDK's non-public `buildMcpParamHeaders` + value encoding (Base64 sentinel for non-ASCII/whitespace/empty values) and add `mcpParamHeadersForTool`. - InspectorClient.attemptToolCall: on a modern connection, build the headers from the tool's declarations + call arguments and attach them to the tools/call request options. `Protocol.request` forwards `headers` to the transport and preserves them across MRTR retry legs, so the direct StreamableHTTP transport applies them. Fixes CLI/TUI. - RemoteClientTransport.requestSend + /api/mcp/send + RemoteSendRequest: forward per-send headers and apply them to the backend's upstream transport.send. The browser can't set cross-origin headers, but the Node backend can — where the Inspector's real request is issued. Fixes web. Verified end-to-end against the live GitHub MCP Server (modern HTTP). Closes #1846 Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> Copilot-Session: 36dbeb09-12b0-4c19-af36-2573772a7dbd * review: harden backend header allowlist, fix breadcrumbs, trim comments Address Copilot review on #1847: - server.ts: restrict client-supplied per-send headers to the `Mcp-Param-` prefix (string values only) via `mcpParamHeadersOnly` before applying them upstream, so the per-send channel can't inject arbitrary headers (e.g. Authorization). `settings.headers` remains the channel for configured upstream headers. Covered by new unit tests. - Fix stale `#1810` breadcrumbs → `#1846` in the two new tests. - Trim the verbose mirroring comments in inspectorClient/types/remote transport. - Drop the redundant base64-on-the-wire integration test (encoding is unit- tested; wire delivery is proven by the verbatim test), remove two unneeded test casts, and cover the boolean `true` branch. Not changed (declined with reason on the PR): buildMcpParamHeaders remains a faithful port of the SDK's helper and does not re-validate values against the declared JSON Schema type — arg types are enforced by schema validation on both sides, and matching the SDK's conforming wire output is the module's goal.

It now mirrors like the plain path. - Extract the two blocks both `tools/call` entry points had duplicated — `convertStringToolArgs` (the string-arg coercion) and `applyMirroredParamHeaders` (the SEP-2243 mirroring) — so the paths can't drift again. That duplication is why the task path was missed. - Regression test: `callToolStream` against the modern `get_weather` server asserts the POST carries `Mcp-Param-City` (verified failing without the fix). - README: the modern-network showcase claimed mirroring is skipped in the browser so the web client gets -32020, and that CLI/TUI mirror. Both are now wrong — the Inspector mirrors itself, on every client. AGENTS: note that xMcpHeader.ts now also builds the wire headers.

It now says the web client's headers are applied by the Node backend that issues the upstream request. - createRemoteFetch: the header comment claimed an `x-mcp-header`-annotated tool is "uncallable from the web client against a strict modern server" — the exact wrong conclusion to reach while debugging a -32020. It now records that the Inspector builds the headers itself, and that they do NOT travel this `/api/fetch` proxy path: they ride the transport's per-send `headers` through `/api/mcp/send`. Copy only — no test asserted the old note text (ToolDetailPanel.test.tsx matches the section title only).

Cliff Hall	40aaf47705	test: deterministic remote-server teardown to kill #1667 afterEach hang (#1763) ... * test: deterministic remote-server teardown to kill #1667 afterEach hang The remote integration tests close their Hono HTTP server in afterEach with `server.close(cb)`, which waits for all keep-alive sockets to go idle before firing the callback. undici's global-fetch connection pool holds sockets open, and under the full parallel/instrumented `npm run coverage` load they may not go idle before the 30s hook timeout — intermittently failing the dead-transport tests in remote-auth-branches.test.ts. The crash-on-startup / dead-session tests are the worst case: they never disconnect, so the session and its dead subprocess transport linger when the server closes. Force the sockets closed with `server.closeAllConnections()` alongside close() so the callback fires deterministically regardless of parallel load, in both remote-auth-branches.test.ts and its sibling connect-crash.test.ts.

That sweep is best-effort cleanup, not work the process must stay alive for — unref it so a pending timer can't keep the event loop (or a test worker) alive for 30s after everything else has finished. Also narrow closeAllConnections() behind an `in` guard in the two remote teardown helpers: ServerType is Server | Http2Server and the method is http1-only, so the direct call failed tsc.

Cliff Hall	99ef731746	Refactor / justify codebase-wide 'as unknown as' casts (#1690) (#1756) ... * core: refactor serverList.ts object↔Record casts into typed helper (#1690) Remove the four pre-existing `as unknown as Record<string, unknown>` / `as unknown as MCPServerConfig` casts in core/mcp/serverList.ts: - stripInspectorFields: rewrite as clone + `delete` over INSPECTOR_FIELD_KEYS. Every Inspector-extension key is optional on StoredMCPServer, so the result is still (a subtype of) MCPServerConfig with no cast. - oauth-strip in extractSecretsFromStored: `oauth` is optional, so a plain `delete stripped.oauth` is legal — drop the cast. - mcpConfigToServerEntries: route the one genuinely-needed widening through a single documented `toRecord(value: object)` helper. Taking `object` makes the single `as Record<string, unknown>` legal (no TS2352), so the double cast disappears from the call site. Net: zero `as unknown as` in serverList.ts; the one remaining structural cast lives inside the audited toRecord helper. Behavior-neutral — existing coverage (79 serverList tests) unchanged; full `npm run ci` passes. Closes #1690 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XNdjEPKLG637X8YmhDiEk5 * core+web+test-servers: eliminate/justify remaining `as unknown as` casts (#1690) Codebase-wide follow-on to the serverList refactor: audit every `as unknown as` double cast outside tests and either remove it or ensure it carries a justifying comment (the review bar is "no *unjustified* double cast"). Removed (widened via a shared helper or narrowed to a single cast): - Promote the serverList `toRecord(value: object)` widening helper to core/json/jsonUtils.ts and reuse it at core/mcp/node/config.ts (normalize loop), core/mcp/remote/node/server.ts (pino level dispatch), and clients/web/src/App.tsx (window global lookup). - inspectorClient.rawWireRequest: type the frame as `JSONRPCRequest` and narrow only `params` with a single structural cast (the SDK's `_meta`-typed params is what blocked direct assignment). - toolOutputValidation: SDK `outputSchema` → `JsonSchemaType` is a single cast. - test-server-fixtures: the optional `task` handle is reachable with a single cast (target field is optional). Justified in place (genuinely unavoidable — private SDK internals, partial interface stubs, third-party/nominal bridges): the inspectorClient private-map accesses, resourceContext + tokenAuthProvider partial `OAuthClientProvider` stubs, the ext-apps peer bridge, modern/legacy `_requestHandlers` bypasses, and the happy-dom `matchMedia` test mock. Behavior-neutral. Full `npm run ci` passes (validate, ≥90 coverage gate, smoke, Storybook).

Revert them for real now — and without re-running Prettier on the file: - core/mcp/inspectorClient.ts: restore the protocolVersion line, task-content array, timeout-reject call, and reconnect guard to their origin/v2/main form, so the file's diff is only the single rawWireRequest cast change. - test-servers/src/modern-tasks.ts: restore the ModernTaskStatus union to its one-line form (the leading-`|` reflow was also Prettier churn), leaving only the new `_requestHandlers` justification comment.

Cliff Hall	fe295396af	Extensions: advertised-extensions toggle in Server Settings (Phase 2 of #1633) (#1743) ... * Extensions: advertised-extensions toggle in Server Settings (Phase 2 of #1633) Adds the debugging knob from #1633: users choose which extensions the Inspector advertises to a server, and a server may register different tools in response. Builds on Phase 1's registry + advertisedExtensions option (#1738). Settings + persistence (core): - InspectorServerSettings.advertisedExtensions + StoredMCPServer field, wired through serverList's read/write converters and INSPECTOR_FIELD_KEY_MAP (omit-when-empty, byte-stable round-trip). - validateSettings (remote PUT route): isBooleanRecord guard + carry a non-empty map; unknown/malformed rejected. - App.tsx threads savedSettings.advertisedExtensions into the client options. UI: - ServerSettingsForm renders an "Advertised Extensions" group of checkboxes driven by ADVERTISABLE_EXTENSIONS; a per-server override wins over the registry default. Modal folds a toggle into settings.advertisedExtensions. Test server + proof: - composable-test-server extensionGatedTools: a tool registered disabled and enabled on `initialized` iff the client declared the mapped extension (getClientCapabilities). Legacy stateful leg. Threaded through load-config/resolve-config; advertised-extensions-http.json showcase + README. - Integration test connects legacy with/without the tasks extension advertised and asserts the gated tool appears/disappears in tools/list — the acceptance criterion, proven end to end, not asserted. Tests: serverList round-trip (non-empty/absent/empty), ServerSettingsForm toggle rows, ServerSettingsModal fold, validateSettings accept/reject, and the integration gating test. npm run ci green (per-file ≥90 gate held).

Matches the omit-when-default policy the other settings use. Only a value that differs from the default is persisted. Adds a modal test asserting the reconvergence (re-checking the sole disabling override drops advertisedExtensions to undefined).

Cliff Hall	ec185f1053	Logging: per-request log level on modern servers (era fork) (#1629) (#1724) ... * Logging: per-request log level on modern servers (era fork) (#1629) On modern (2026-07-28) servers `logging/setLevel` and the session-scoped level are gone: the client opts into logs per request via the `io.modelcontextprotocol/logLevel` `_meta` key, and the SDK does not attach it automatically, so server logs are silently absent until stamped. Core (`InspectorClient`): - `setModernLogLevel(level | undefined)` / `getModernLogLevel()` store the opt-in level; `mergeMeta` stamps it on every outgoing request, gated on the negotiated modern era so legacy connections are untouched. - Cleared on disconnect so it can't leak into the next connection. Web UI: - `LogControls` forks on `protocolEra`: legacy keeps the `logging/setLevel` selector + Set button; modern shows a per-request opt-in Select (Off + levels, applied immediately) with copy explaining logs arrive on the originating request's stream. - Threaded `protocolEra` / `modernLogLevel` / `onSetModernLogLevel` through LoggingScreen and InspectorView from App. Tests: unit coverage for the modern LogControls/LoggingScreen fork; integration coverage proving the `logLevel` `_meta` is stamped on a real modern server once opted in (and not on legacy).

The Logs tab shows the legacy session-scoped "Set Active Level" selector + Set button; calling the tool streams logs. - logging-modern-http.json: same, with `transport.modern: true`. Connect with Protocol Era = Modern and the Logs tab shows the per-request opt-in control; the client stamps `_meta["io.modelcontextprotocol/logLevel"]` on every request (visible in the Network tab request body). pr-screenshots/ documents the verified behavior end-to-end against both real servers: the legacy control with logs streaming, the modern per-request control, and the modern tools/call request body carrying the stamped logLevel _meta.

On the modern (2026-07-28) stateless leg that isn't tied to the in-flight request, so the SDK answered the tool call with plain JSON and dropped the log — nothing reached the Inspector's Logs panel. Prefer the per-request `extra.sendNotification` (rebuilt from `ctx.mcpReq.notify`): scoped to the current request, it makes the SDK upgrade the response to SSE and stream the log back on the originating request's stream. Falls back to the global notifier (legacy path / no per-request context). Verified end-to-end: opting in via the Logs-tab "Log Level per Request" control and calling send_notification now streams the entry on the modern server; legacy behavior unchanged (server-notification integration tests green). README documents the modern logging showcase and the caveat that this test server streams whenever a tool emits — the SDK beta strips the per-request envelope from the handler context, so the tool can't gate on the client's logLevel opt-in (the client-side `_meta` stamp #1629 owns is still fully visible in the Network tab).

The SDK already provides the correct primitive: `ctx.mcpReq.log(level, data, logger)` (added in `McpServer.buildContext`). It applies the era-correct threshold gating itself — on the modern (2026-07-28) leg it reads the per-request `logLevel` opt-in from the request envelope and drops the message when the client didn't opt in or the level is below the requested severity; on legacy it honors the session level from `logging/setLevel` — and emits through `notify`, so the modern response still upgrades to SSE and the log rides the originating request's stream. Surface it as `extra.log` (`toHandlerExtra` maps `ctx.mcpReq.log`) and have `send_notification` prefer it, falling back to the global notifier for callers without per-request context. Verified end to end: opting in via the Logs-tab "Log Level per Request" control stamps `logLevel` in the request `_meta` and streams the log; setting it back to Off omits the key and the server gates the log (plain JSON response, no notification). Legacy server-notification integration tests still green. (No SDK change needed — the earlier apparent gap was our test server using the wrong low-level API.)

Field added to `InspectorServerSettings` and `StoredMCPServer`. - serverList.ts: round-trip the field (lift on read, omit-on-default on write, drop unknown literals) mirroring `protocolEra`; add to the persisted field allowlist. - remote/node/server.ts: validateSettings accepts/validates it and the normalize path drops a malformed literal. - inspectorClient.ts: the constructor seeds `modernLogLevel` from the setting (`"off"` → not opted in), so a modern connection stamps the level from the first request without UI interaction. mergeMeta still gates on the modern era. - ServerSettingsForm/Modal: a Select (Off + 8 levels) with a modern-era description. App seeds the live Logs-tab control from the setting on connect so the two stay in sync. Tests: form Select (default/onChange/off/reflect), modal handler, serverList round-trips, route validation (accept/reject/drop), and constructor seeding (seeded level stamped from the first request; "off" opts out). The prior modern-era "stamps once set" test is updated for the new default-on behavior. Coverage gate green.

Add two live e2e tests against a modern (`createMcpHandler`) server serving the `send_notification` tool with `logging: true`: - opted-in (server setting = a level): calling the tool delivers a `notifications/message` over the request's SSE stream, with the right level/logger/data. - not opted in (setting "off"): the tool still returns a result, but the server gates the log — no `notifications/message` is received. This exercises the full path end to end: the client seeding + `_meta` opt-in, and the server's `send_notification` → `ctx.mcpReq.log` era-correct gating.

It stays visible for a pinned "modern" server, and for an "auto" server that is either not yet connected (era unknown) or resolved to modern. Threads the negotiated era down: App passes `negotiatedEra` to ServerSettingsModal only when the settings target is the live-connected server (`connectionStatus === "connected" && settingsModalTargetId === activeServerId`); the modal forwards it to ServerSettingsForm, which gates the control on `configuredEra === "modern" || (configuredEra === "auto" && negotiatedEra !== "legacy")`. Tests: visibility matrix on the form (legacy hidden; auto+legacy hidden; auto+unconnected and auto+modern and modern shown) and a modal hide case; the existing modern-log tests now base on a modern-era settings object. Verified in the browser (legacy hides, switching to modern reveals it reactively) and with the full `npm run ci` (green across all clients).

Cliff Hall	b3b04c6939	Thread cacheMode through managed list refresh via SDK cache-aware verbs (#1721) (#1723) ... * Thread cacheMode through managed list refresh via SDK cache-aware verbs (#1721) Manual/auto refresh of tools/resources/prompts now forces a cache-bypassing round trip on modern servers, delivering the raw-request cacheMode control deferred from #1628. The InspectorClient list/read path uses the SDK's single-page `client.request` verbs (for pagination debugging), which never consult the SDK response cache — so `cacheMode` was inert there. This adds a separate aggregate path that routes through the SDK's cache-aware high-level verbs, where `cacheMode` is honored: - InspectorClient: new `listAllTools/Prompts/Resources/ResourceTemplates( { cacheMode, metadata })` that call `client.listTools()` etc. (all-page aggregate + SEP-2243 x-mcp-header exclusion + cache consult/write). A shared `getCacheableRequestOptions` / `aggregateListParams` back all four. - InspectorClientProtocol: the four `listAll*` methods added. - ManagedListState: delegates page walking to the SDK verb (config `fetchPage` loop → `fetchAll`); `refresh(metadata?, cacheMode?)` threads cacheMode. A `list_changed` auto-refresh bypasses the cache (`cacheMode: "refresh"`). - Managed hooks: user-initiated `refresh()` passes `cacheMode: "refresh"`, so the existing per-tab Refresh buttons become genuinely cache-bypassing — no App wiring change. Connect-time load stays default (`'use'`). The single-page `listTools(cursor)` primitive is unchanged; the paged hooks still surface per-page `nextCursor`.

Sidebars widened 340→360 so the controls don't crowd list entries. - Test server: `test-servers/configs/pagination-http.json` (12 tools/resources/ prompts, page size 4 → 3 pages each) exercises the flow end to end.

The connect-time all-page skip now applies only to lists with a paged counterpart (new `deferInSinglePage` flag on ManagedListConfig; false for resource templates), so templates still aggregate on connect regardless of the setting. - Guard `PagedTools/Prompts/ResourcesState.loadPage` against a concurrent load (fast double-click on "Load next page") so the same page can't be appended twice; the in-flight load owns the cursor and the second call is a no-op. - Thread ambient auth recovery through the single-page refresh, Load-next-page, and mode-switch loads (they previously bypassed it) — usePaginatedList's onRefresh/onLoadMore now return their promises so App can wrap them. - Drop the misleading "aggregated list" wording from the paged-store docs.

If updateServerSettings rejects, the optimistic `singlePageListsOverride` is now cleared and the live client setting rolled back (the effect only clears the override when the persisted value changes, which doesn't happen on failure), so the UI and client reflect what's on disk rather than the failed edit. Added an App test for the revert path.

Expose `clearListChanged` from useManagedTools/Prompts/Resources and call it in the single-page branch of onRefreshTools/Prompts/Resources. Tests added. UI polish (user feedback on the sidebar control): - Rename the switch label "Single page" → "Paginated". - Put "Load next page" on the same row as the switch, space-between (switch fully left, button fully right). - Move the "N pages loaded" status to its own line below the row, centered. - Hide the whole control once the list is known to be a single page (single-page mode, page 1 loaded, no nextCursor) — nothing to paginate. pr-screenshots refreshed to the new layout. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XNdjEPKLG637X8YmhDiEk5 * Rename the singlePageLists setting to paginatedLists for clarity (#1721) `singlePageLists` read backwards from the "Paginated" switch label (it sounds like paginated=false). Rename the server setting to `paginatedLists` with the same value meaning — true = paginated/one-page-at-a-time, false = aggregate-all — and follow through on the related identifiers for consistency: - Setting field `paginatedLists` across ServerConfig / InspectorServerSettings, serverList convert/default, node + remote settings paths, and the form/modal callbacks (onPaginatedListsChange). - `usePaginatedList` / `ListPaginationControls` prop `singlePage` → `paginated`, `onSinglePageChange` → `onPaginatedChange`. - `ManagedListConfig.deferInSinglePage` → `deferWhenPaginated`. - App state (paginatedListsOverride, onTogglePaginatedLists, …) and all tests/fixtures + mode-referring comments. "single-page" wording that denotes the SDK's one-page `client.request` verb (inspectorClient) is intentionally left as-is. Purely a rename — no behavior change; unit + integration + cli + tui + coverage all green.

Cliff Hall	e026051b47	Era-aware connection model & capability gating (#1626) (#1697) ... * Era-aware connection model & capability gating (#1626) Make protocol era (SEP §7.8) a first-class, per-server connection dimension, orthogonal to the transport type, and drive the SDK Client's versionNegotiation from it. 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`. Web UI - ServerSettingsForm: a Protocol Era selector bound to the per-server setting. - ConnectionInfoContent: era-aware — Era badge, Session ("Sessionless" on modern), and a Discovery section (supported versions + extensions) from the `server/discover` result. CLI/TUI also map the mcp.json `protocolEra` into versionNegotiation so the field applies uniformly. Version negotiation stays fully client-side; modern connect works over the existing remote tunnel and disconnect is sessionless (the SDK skips DELETE when there is no session id). Mcp-* header fidelity is left to the History/Network card.

Keeps the exhaustive switch intact. - ConnectionInfoContent: the Session row is HTTP-only — show "N/A (stdio)" for stdio instead of the misleading "Session-based". - AGENTS.md: add a rule against unjustified `as unknown as` double casts, and drop the one such cast introduced in the serverList test.

Cliff Hall	7fecebed5e	OAuth: re-key store to (server, issuer) + SEP-837/2350/2352 auth UX (#1694) ... * OAuth: re-key store to (server, issuer) + SEP-837/2350/2352 auth UX (#1625) Re-key the persisted OAuth store to (server, issuer) and add the SEP-837/2350/2352 authorization-hardening UX. The SDK v2 auth() drives the SEP-2352 flow off the provider's ctx.issuer; the Inspector's job is to honor it and round-trip the issuer stamp. SEP-2352 — issuer-bound credentials - ServerOAuthState nests issuer-bound credentials under byIssuer[issuer] = { clientInformation, clientRegistrationKind, tokens }, with an activeIssuer pointer answering the transport's ctx-less per-request bearer read. - Fix a latent bug: OAuthStorageBase re-parsed tokens/client-info through OAuthTokensSchema/OAuthClientInformationSchema, which strip the non-RFC `issuer` field and silently defeat the SDK's discardIfIssuerMismatch. The store re-attaches the stamp from the byIssuer key. - BaseOAuthClientProvider threads ctx.issuer and implements discoveryState()/saveDiscoveryState() (activates the SDK's callback-leg AuthorizationServerMismatchError binding check) and invalidateCredentials(). - Lazy, migration-free upgrade: a legacy pre-1625 blob's top-level clientInformation/tokens are returned as an unkeyed fallback until the first issuer-stamped save promotes them into byIssuer. SEP-837 — application_type - DCR declares application_type: "native" (localhost Inspector). - ClientSettingsForm renders RegistrationRejectedError detail and reflects DCR's deprecated-in-favor-of-CIMD (SEP-991) status. SEP-2350 — step-up scope union - Per-server onInsufficientScope (reauthorize | throw) setting wired ServerSettingsForm -> StoredMCPServer.oauth -> StreamableHTTPClientTransport. - StepUpAuthModal visualizes the prior-union-challenged scope set, tagging each scope `new` vs `already granted`. mcpAuth simplification - Delete the hand-rolled authorizeWithoutRefresh (mishandled issuer stamping); forward forceReauthorization/skipIssuerMetadataValidation to native SDK auth() so both the initial and step-up paths get SEP-2352 stamping. Vocabulary + docs - OAuthStep gains cimd_fetch / issuer_comparison / scope_step_up (recorded on a step-up redirect); the Network tab labels auth requests by OAuth phase. - v2_auth_hardening.md gains an as-built status section. Deferred to the era-aware card: the SdkError(EraNegotiationFailed) -> UnauthorizedError unwrap and finishAuth(URLSearchParams) form (only fire under non-legacy negotiation). Closes #1625 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * Address @claude review: issuer-stamp source gating + clear/activeIssuer + phase over-match - SEP-2352: stamp the issuer only when the credential actually came from the byIssuer slot (`fromSlot`), not merely when a slot exists. A partially-populated slot alongside a surviving legacy field would otherwise stamp a legacy (possibly cross-AS) credential with the current issuer, defeating discardIfIssuerMismatch. - Issuer-scoped clears no longer promote the cleared issuer to `activeIssuer` (updateIssuerSlot gains a `setActive` flag; save paths keep the promotion). - oauthNetworkPhase matches register/token/authorize as the final path segment (trailing slash tolerated) so `/token/refresh` or `/api/register/foo` no longer over-match. - Tests for all three.

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).

Display the single-source version (root package.json) in the web UI's lower-right corner, in grey — matching the CLI and TUI. The browser can't read the filesystem, so the version flows backend → browser via GET /api/config: - Add `version?: string` to InitialConfigPayload; the web backend (webServerConfigToInitialPayload) reads it once via the shared readInspectorVersion() and tags it onto the payload. - Add a `useInspectorVersion` hook mirroring useSandboxUrl/useServerListWritable. - Add a presentational `VersionBadge` element rendered fixed lower-right, grey, non-interactive; styling lives in a `versionBadge` Text theme variant (no inline styles, --inspector-* tokens). - Wire it into App.tsx. Verified live: /api/config serves `version: "2.0.0"` and the badge renders `v2.0.0` fixed at the lower-right in grey.

Add `envRecordToPairs` / `envPairsToRecord` helpers. - `env`/`cwd` remain config-owned on disk (the standard mcp.json location): the `/api/servers` PUT route writes an edited settings.env/cwd back onto the stored stdio config on a settings-only patch (supporting clear), and a config-providing PUT keeps config authoritative. `validateSettings` accepts `env`/`cwd`. - Server Settings modal: Working Directory field in Options and a dedicated collapsible Environment Variables section — both STDIO-only. - Registry server.json import sets no `cwd` (the schema has no working-directory concept); documented in serverJson.ts. Tests: serverList converter round-trip, route write-through (set/clear, config-precedence, non-stdio no-leak, validation), import preservation (client-config cwd, registry cwd skip), and form/modal component coverage. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(web): preserve config env/cwd when a settings PUT omits them (#1515 review) Address Claude's review of #1518. - `/api/servers` PUT now distinguishes an *absent* `env`/`cwd` (preserve the stored value) from an explicit empty list / blank string (clear). Previously `validateSettings` coerced a missing `env` to `[]`, so an env-unaware caller patching only a timeout would silently wipe the server's env/cwd. The integrated web client always resends the full GET-rehydrated env, so it was unaffected — this protects the raw HTTP contract. - `validateSettings` reports `envProvided`/`cwdProvided`; the write-through only touches `config.env`/`cwd` for fields the caller actually sent. - On the omit path, rehydrate the untouched env's keychain values onto the rebuilt entry so the secret reconcile re-persists them rather than sweeping the blanked-on-disk keys out of the keychain. - Minor: guard the stdio cast in `mcpConfigToServerEntries` on the transport type instead of casting unconditionally. - Test: settings-only PUT omitting env/cwd preserves config keys + cwd + the keychain secret.

Per-server review with import/skip on new servers and overwrite/skip/rename on id conflicts, then a per-server outcome summary. - Import server.json: parse the MCP registry single-server format (npm/pypi/oci packages + remotes, env vars, package/runtime args, URL template vars) into a runnable config, with a file picker and debounced live validation; Add Server is disabled until validation passes. Core gains an isomorphic import strategy layer (core/mcp/import) with a strategy registry, client-config + server.json parsers, a strategy-agnostic merge, and a dependency-injected source resolver. useServers exposes importSource().

Cliff Hall	91f02fd6db	feat(web): catalog vs read-only session launch model + apply --header (#1481, #1483) (#1496) ... * feat(web): catalog vs read-only session launch model + apply --header (#1481, #1483) Per specification/v2_catalog_launch_config.md, `mcp-inspector --web` now selects the backend's server-list source and a session-wide writability, instead of seeding an inert `initialMcpConfig` the UI never read: - `--catalog <path>` (and `MCP_CATALOG_PATH`) → active WRITABLE catalog (seed/CRUD/watch), like the default catalog. - `--config <path>` → READ-ONLY session file: served in the UI but never written, seeded, or plaintext-secret-migrated — safe to point at a foreign config (e.g. claude_desktop_config.json). - ad-hoc `--server-url`/command (+ `--header`) → one server held IN MEMORY (no file written); `--header` is lifted onto the entry so the seeded connection actually uses it (closes the #1483 warn-only no-op). - nothing → default catalog (writable), unchanged. Backend (`createRemoteApp`): new `writable` + `initialServers` options. GET /api/servers branches three ways (in-memory / read-only file with no seed+no migrate / writable catalog); the four mutating routes return 403 when read-only; `/api/config` carries `writable`; the file watcher is skipped for in-memory sessions. `--catalog`/`--config` are mutually exclusive and neither combines with an ad-hoc target or `--header`; `--header` requires an ad-hoc HTTP/SSE server (clear errors otherwise — no silent no-op). UI: `useServerListWritable` reads `writable` from /api/config; the Servers screen hides add/edit/clone/remove/reorder/settings and shows a read-only banner when false. All new props default to writable=true (back-compatible). Docs: spec gaps G2/G3/G4 updated; launcher README documents the flags. Verified end-to-end against the built launcher: --config (writable:false, file byte-stable, mutations 403), ad-hoc --header (in-memory, header lifted), and --catalog (writable:true, POST persists). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * refactor(web): address review — Mantine <Code> in read-only banner, clarify watcher comment - Replace raw <code> with Mantine <Code> in the read-only-session Alert (repo convention: prefer Mantine primitives over raw HTML). - Add a comment near `watchable` clarifying that a read-only `--config` file is still watched on purpose (read-only blocks UI writes, not external observation; `writable` does not gate watching). Deferred (per reviewer): consolidating useSandboxUrl + useServerListWritable into one useConfig hook to avoid the duplicate /api/config fetch — optional follow-up. The redundant ad-hoc header type-guard is kept as defensive.

Cliff Hall	53dc4549be	fix(core): trace dropped fetch body update when entry rotates out (#1390) (#1480) ... * fix(core): trace dropped fetch body update when entry rotates out (#1390) FetchRequestLogState.onFetchRequestBodyUpdate silently dropped a deferred response-body update when the matching entry had already been evicted by log rotation (>= maxFetchRequests newer requests appended between the append and the fire-and-forget body read). The user saw an empty Response Body with no way to distinguish "body never came back" from "body dropped after eviction". Plumb an optional pino logger into FetchRequestLogState (defaulting to the silent logger) and emit a logger.debug at the early-return site so the drop is traceable. The web client wires the existing remote logger from createWebEnvironment into the state manager. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(core): emit dropped-body trace at warn level so it is observable (#1390) Review feedback: the web remote logger (createRemoteLogger) defaults to level 'info' with no override at the environmentFactory call site, so a logger.debug at the drop site is filtered out by both the pino level gate and transmit.level — the diagnostic never reaches /api/log and the drop stays invisible in the shipped web app, defeating the issue's goal. Promote the trace to logger.warn (>= info, so it transmits by default). A response body lost to log rotation is unexpected data loss, not routine diagnostic noise, so warn is the appropriate severity. Update the comment to explain the level choice and switch the test stub from debug to warn, extracting a small typed makeWarnLogger helper per review. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * feat(web): configurable Network Log Size per server + body-dropped toast (#1390) Turn the otherwise-invisible "response body dropped after rotation" case into an actionable signal: 1. Per-server `maxFetchRequests` setting (default 1000, 0 = unlimited), editable as "Network Log Size" in the first (Options) accordion section of the Server Settings form. Plumbed through the full settings pipeline: InspectorServerSettings + StoredMCPServer types, the serverList disk converters (read defaults to 1000, write omits the default to keep diffs minimal — 0 is a meaningful non-default), and the node server's GET-sanitize + write-side validateSettings (non-negative number). Applied live to the active connection on settings-modal close via a new FetchRequestLogState.setMaxFetchRequests (shrinking trims immediately), and at connect time for the next session. 2. FetchRequestLogState now emits a `fetchRequestBodyDropped` event, but only for genuine rotation drops (log at capacity with a finite cap) — not for benign post-clear stragglers or unlimited logs, which previously also hit the warn path. App shows a deduped, persistent toast (stable per-server id, no auto-close) explaining what happened and the likely causes, with a link that opens this server's settings on the Options section (modal remounts via key) so the user can raise the limit if it's just a high-traffic server. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(web): don't treat a cleared Network Log Size field as unlimited (#1390) Review feedback: clearing the NumberInput emits "", and `parseInt("") || 0` coerced that to 0 (unlimited). Since the value applies live on modal close, a user who cleared the field to retype and then closed the modal would silently switch the log to unlimited. Fall back to the current value on an empty/NaN parse and reserve 0 for an explicit numeric entry. Adds a cleared-input test.

Cliff Hall	d5f12b2a82	feat(web): reorderable ServerCards — drag-and-drop + keyboard (#1369) (#1447) ... * feat(web): reorderable ServerCards — drag-and-drop + keyboard (#1369) Let users control the order of servers on the Servers screen instead of hand-editing mcp.json. Each ServerCard gets a grip handle (in the header, left of the name) that drives an @dnd-kit sortable; pointer and keyboard sensors both work, with live-region announcements for screen readers. - Backend: PUT /api/servers/order rewrites mcp.json in the supplied order inside the write lock, reusing the atomic-write + watcher-notify path. Registered before /:id so "order" isn't captured as a server id. Rejects with 409 when the id set no longer matches disk and 400 on duplicate / malformed bodies, so a reorder racing an external edit can't drop or duplicate an entry. - Hook: useServers.reorderServers(orderedIds) — optimistic local reorder, PUT, refresh-to-disk-truth on failure. - UI: SortableServerCard wrapper owns the dnd-kit concerns; ServerListScreen wraps the grid in DndContext + SortableContext (rect strategy) with pointer + keyboard sensors and announcements. Reorder math and a11y copy extracted to reorderIds.ts / serverReorder.ts for direct unit testing. Renders plain cards (no grip) when no onReorder is wired. - Wired onServerReorder through InspectorView -> App.tsx. Tests: pure-helper units, hook (persist / optimistic / 409 revert), 9 backend integration tests (incl. id-set-mismatch rejection and the route-registration guard), ServerCard/ServerListScreen units, and a real-browser Storybook keyboard-reorder play (the dnd-kit keyboard sensor needs layout rects that happy-dom doesn't provide).

Cliff Hall	b0a024269e	feat(web): list-changed handling — indicator, pull-on-demand default, and per-server auto-refresh opt-in (#1402) (#1443) ... * feat(web): wire the listChanged indicator across all screens (#1402) The per-screen list-changed indicator was hardcoded false in InspectorView for Tools, Apps, Prompts, and Resources, so it could never light up. Source it from the managed-state layer instead. Each ManagedXState now tracks a listChanged flag: set true when its */list_changed notification arrives (the existing auto-refresh leaves it set), exposed via getListChanged()/a listChangedChange event, and cleared by clearListChanged() or on disconnect. The useManagedX hooks surface the flag and clear it on a user-initiated refresh (the indicator's Refresh button = acknowledge). App threads the three flags to InspectorView, which maps them to the screens — Apps shares the tools flag since apps are a filtered view of tools. Tests cover set/clear/disconnect at the state-manager layer, the hook subscription + refresh-clears behavior, and the InspectorView routing (including Apps sharing the tools flag and no cross-wiring between screens). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(core): close clear-after-await race in managed-list refresh (#1402 review) The useManagedX refresh() callbacks cleared the listChanged flag AFTER awaiting the fetch. If a */list_changed arrived mid-fetch, the state re-set the flag (and auto-refreshed), then the trailing clear wiped that genuinely-new signal. Clear BEFORE the await instead: the user's refresh acknowledges only the change in hand, and a mid-fetch change re-sets the flag and survives. Adds a race regression test on the tools hook. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(web): drop duplicate Refresh on the Apps screen (#1402) AppControls uniquely had a standalone toolbar Refresh button AND the ListChangedIndicator on a separate row, so once the indicator could actually appear (this PR), the Apps screen showed two Refresh buttons. Match the other three controls (Tools/Prompts/Resources): the indicator is the single header-right refresh affordance. Updates AppControls and AppsScreen tests to assert exactly one Refresh (and none when the list hasn't changed). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * feat(core): stop auto-invoking */list on list_changed; user pulls via Refresh (#1402) With auto-refresh on, the list was already current by the time the list-changed indicator appeared, making its Refresh button moot. Now the managed Tools/Prompts/Resources state managers only flag the change on */list_changed (they no longer auto-refresh); the list stays as-is until the user clicks Refresh, which fetches the new list and clears the indicator. The connect-time initial load is unchanged. Resource templates (no own indicator, part of the Resources screen) also stop auto-refreshing; onRefreshResources now refreshes both resources and templates, since a single resources/list_changed covers both. Tasks are left auto-refreshing — they have no list-changed indicator and need live status updates. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * docs(core): correct ManagedResourceTemplatesState header comments (#1402 review) The class no longer subscribes to resourceTemplatesListChanged; update the stale file/class docstrings that still claimed it syncs on that notification to reflect connect + statusChange only. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * feat(web): add per-server 'Auto Refresh on List Changed Notifications' option (#1402) New Options section in ServerSettingsForm with a single checkbox. When checked, the managed Tools/Prompts/Resources (and resource templates) state auto-refreshes on */list_changed notifications; when unchecked (default) the notification only lights the list-changed indicator and the user pulls via Refresh. Plumbing: new optional autoRefreshOnListChanged on InspectorServerSettings and StoredMCPServer, round-tripped through serverList (lifted with a false default, persisted only when true, added to the exhaustive field-key map); surfaced from InspectorClient via a new getServerSettings() on the protocol; the state managers read it live at notification time to decide auto-refresh vs flag-only. Resource templates re-subscribe to their list_changed but only auto-refresh when the option is on (they have no indicator of their own). Tests cover the round-trip (true persists, false omitted), the form section (render/checked/toggle), and each state manager's on/off branch. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(server): persist autoRefreshOnListChanged through validateSettings (#1402) The PUT /api/servers write path runs settings through validateSettings, which rebuilds the value from explicitly-named fields and silently drops unknown keys — so autoRefreshOnListChanged never reached disk (the serverList round-trip test passed because it calls inspectorSettingsToStoredFields directly, bypassing this path). Validate it as an optional boolean and include it in the built value; false is omitted on disk by inspectorSettingsToStoredFields as before. Adds integration tests over the real PUT path: true persists, false is omitted, and a non-boolean is rejected (400). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * feat(web): default the Server Settings modal to the Options section (#1402) Open 'Options' instead of 'Custom Headers' when the Server Settings modal first opens, so the new Auto Refresh toggle is the first thing surfaced. Updates the modal default-expanded section, the modal test's initial-state assertions, the three header tests (now expand 'Custom Headers' first since it's no longer open by default), and the story defaults.

Cliff Hall	49d6be6987	feat(web): add per-server Roots config + client roots capability (#1425) (#1431) ... * feat(web): add per-server Roots config + client roots capability (#1425) Add MCP roots support to the v2 web Inspector as a per-server config section in the server settings form (no separate Roots tab/screen). - Persistence: add `roots: Root[]` to `InspectorServerSettings` and `StoredMCPServer`; thread through serverList converters (lift on read, drop empty-uri rows / blank names on write, omit when empty) and the remote server's read-side drop guard + `validateSettings`. - Capability: `setupClientForServer` always advertises the roots capability (`roots: cleanRoots(savedSettings?.roots ?? [])`) so the server can issue `roots/list` and receive `roots/list_changed`. - Live apply: edits to a connected server's roots are pushed via `inspectorClient.setRoots(...)` once, on settings-dialog close — diffed against the client's current roots — rather than per keystroke, to avoid flooding the server with `roots/list_changed` / `roots/list`. - Form: new Roots accordion section with a required URI and an optional name per row (unlike v1, which was URI-only), + Add Root, and remove. Tests cover the persistence round-trip (serverList + servers-route), the form/modal section, and reuse the existing InspectorClient roots/`setRoots` integration coverage. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * refactor(roots): address review — dedup guards/cleanRoots, preserve extra fields, test live-apply Responding to the PR #1431 code review: - Dedup `isRootArray`: drop the copy inside `validateSettings` and reuse the module-scope guard the read path uses, so the two can't drift (core/mcp/remote/node/server.ts). - Dedup the clean-roots normalizer: hoist a single exported `cleanRoots` into core/mcp/serverList.ts and reuse it from both `inspectorSettingsToStoredFields` and App.tsx (drops the local copy). - Preserve non-form root fields (e.g. `_meta`): `cleanRoots` now spreads the carried-through fields and only normalizes uri/name, and the modal's `handleRootChange` spreads the existing root on edit — so a hand-edited root's `_meta` survives load + persist + edit instead of being silently dropped. - Test the App live-apply-on-close path: new App.test.tsx cases assert setRoots is called once with cleaned roots when changed on the active server, and not called when the cleaned roots already match what the client advertises. Adds a cleanRoots unit test (blank drop + _meta preserve).

Adds `NetworkControls` + `NetworkStreamPanel` + `NetworkEntry` groups, a `monoBreak` Text theme variant for long header values, and wires onClearNetwork / onExportNetwork (JSON download) from `App.tsx`. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(network): include request / response bodies in search filter Headers were already covered but bodies were not, so searches for strings that live inside the JSON-RPC payload (e.g. "jsonrpc", "initialize", a tool name) silently returned no matches. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(network): always render Response Body section, note streaming Streaming responses (text/event-stream, application/x-ndjson, POST to /mcp) are intentionally not body-captured by the fetch tracker, so the section was silently omitted. Now whenever a response was received we render the section, with either the body, a "(empty)" note, or a "Streaming response — body not captured" note keyed off content-type. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(network): capture response bodies via async body-update events Two related fixes: 1. The fetch tracker was marking every streamable-HTTP POST /mcp call as "not captured" because the response content-type is text/event-stream. In practice those streams are bounded — the server sends the JSON-RPC reply (sometimes preceded by progress events) and closes — so we can clone the body and read it. Only GET + SSE / ndjson is the unbounded long-lived channel that has to stay uncaptured. 2. Reading the body inline blocked the transport from processing progress notifications until the entire stream finished, breaking the `resetTimeoutOnProgress` integration test. The body is now read in the background and dispatched via a new `fetchRequestBodyUpdate` event that the FetchRequestLogState patches into the matching entry by id. Plumbing wires through node/transport, the remote SSE channel (RemoteSession, RemoteClientTransport), and the remote event types. Also hides the Network tab when the active server is stdio (no HTTP traffic to surface) and bumps the inline body preview limit to 100 KB so typical tools/list responses render rather than tripping the "too large" notice. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat(network): show orange SSE badge for long-lived stream entries Adds a small "SSE" badge to the right side of the NetworkEntry header (left of the HTTP status badge) when the response is a long-lived streaming channel (GET + text/event-stream or application/x-ndjson) — the only case where the body genuinely isn't captured. Makes the "not captured" placeholder less surprising at a glance. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(network): address PR review findings - Stop capturing OAuth response bodies (drop updateResponseBody from the effectiveAuthFetch tracker). Restores pre-PR behavior for auth-category entries so live access_token / refresh_token values can't leak into the Network tab body preview during a screen-share. Headers + status are still tracked. - Extract `isLongLivedStreamResponse(method, contentType)` to core/mcp/fetchTracking so the rule lives in one place; consumed by the tracker and the NetworkEntry UI placeholder. - Document the intent of NetworkEntry's `useEffect` (the list-level toggle is authoritative; per-entry overrides are intentionally discarded on each list toggle). - Rename MAX_INLINE_BODY_BYTES → MAX_INLINE_BODY_CHARS (`.length` is UTF-16 code units, not bytes) and update the user-facing notice. - Switch NetworkStreamPanel's search from joined-string `.includes` to per-field `.some(.includes)` so a term can't span field boundaries. Regression test added. - Add aria-label to ListToggle ("Expand all" / "Collapse all") — both an a11y improvement and a stable selector that lets the panel test stop fishing the button out by text-content negation.

Cliff Hall	037225a9fb	feat(servers): move oauthClientSecret and stdio env values to OS keychain (#1356) (#1360) ... * feat(servers): move oauthClientSecret and stdio env values to OS keychain (#1356) mcp.json is designed to be tool-shareable (symlinked from Claude Desktop's config, pasted into bug reports, synced via dotfiles), so storing OAuth client secrets and stdio env values in plaintext there meant any of those flows could leak them. Lift both into the OS keychain via @napi-rs/keyring (active replacement for the archived keytar). The wire shape is unchanged: the GET /api/servers handler rehydrates from the keychain so browser code sees the same JSON; the on-disk file no longer contains the secret material. Includes an idempotent migration that lifts plaintext from older mcp.json files (or hand-edited ones) into the keychain on first read. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(servers): tolerate keychain unavailability on non-set ops (#1356) CI on Linux failed because `@napi-rs/keyring` hard-errors without libsecret, and the route handlers were touching the keychain even for no-secret flows (defensive `deleteAllForServer` on POST/DELETE, sweep on PUT). The user's intent for the Linux fallback was "hard fail when a secret is actually involved" — not on every keychain touch. Make `KeyringSecretStore.get / delete / deleteAllForServer` silently degrade when the keychain is unavailable (return null / no-op); `set` remains the one operation that hard-fails with `KeychainUnavailableError`. The migration path catches the error and preserves the disk plaintext rather than losing the secret. Also inject `InMemorySecretStore` in `useServers.test.tsx` and `servers-events.test.ts` so tests never touch a developer's real keychain even when libsecret is present. Adds `KeyringSecretStore` tests (vi.mock'd native bindings) and an integration suite that simulates Linux-without-libsecret to verify the tolerance contract end-to-end. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(servers): close GET migration race; reverse keychain/disk order (#1356) Addresses code review: 1. **Concurrency**: GET /api/servers was reading + migrating outside the write lock, then writing inside it — a concurrent POST/PUT/DELETE between the read and the lock acquisition could be clobbered by the migration write. Also affected the first-launch seed write. Fix: take a fast unlocked peek; if the file is absent (seed branch) or carries plaintext to migrate (migration branch), re-read inside the write lock and decide there. Added `hasPlaintextSecrets()` as a pure predicate so the common no-migration path stays lock-free. 2. **Write ordering**: POST and PUT wrote disk first, then keychain. A keychain `set` failure mid-write left a half-configured entry on disk and trapped retries at 409. Reversed to keychain-first so a 503 leaves both stores in their pre-write state. PUT in-place now sets new fields, writes disk, then deletes obsolete fields (a failed disk write leaves orphan keychain entries — recoverable — rather than premature deletions of fields the user still expects to see). 3. **Tolerance simplification**: dropped the no-entry regex in `KeyringSecretStore.delete` — both "no entry" and "keychain unavailable" collapse to the same desired outcome (the entry isn't there anymore), so a uniform swallow is clearer. 4. **Parallelism**: `readKeychainEntriesFor` now `Promise.all`s the per-field `get` calls. macOS Keychain round-trips are 10-50ms; serializing 5+ env vars per server × N servers is a meaningful wall-clock cost on GET. 5. **Spec doc**: reflects the tolerance contract (only `set` hard-fails) and the keychain-before-disk write ordering rationale. New regression test in servers-route.test.ts covers the retry-after-503 contract directly. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * chore(servers): parallel keychain writes + migration partial-state comment (#1356) Two nice-to-have observations from the re-review: - `writeKeychainEntriesFor` now `Promise.all`s its per-field sets, matching the read side. No ordering requirement among distinct (id, field) keys; on unavailability every set rejects and Promise.all surfaces the first rejection (still 503 from the route handler). - `migratePlaintextSecrets` catch block now spells out the partial-migration semantics: we return the original config so the disk plaintext stays intact, and the next successful GET retries with the keychain-wins branch absorbing already-set entries. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * chore(servers): parallel keychain deletes for symmetry (#1356) Picks up the symmetry observation from the third review: `deleteKeychainFields` now uses `Promise.all` like its read and write siblings. Distinct (id, field) deletes have no ordering requirement, and `secretStore.delete` is already a silent no-op on unavailability so Promise.all has no failure-mode surprise.

Cliff Hall	a9df501856	feat(servers): flatten mcp.json settings to top-level fields (#1358) (#1359) ... * feat(servers): flatten mcp.json settings to top-level fields (#1358) Eliminate the nested `settings` block introduced in #1352 so each server entry's Inspector-extension fields live as direct keys alongside `type` / `url`, matching the `.mcp.json` shape Claude Code / Cursor / Cline write: - `headers` becomes a `Record<string, string>` on disk (was nested `settings.headers` as a pair-array) - `oauth` becomes a nested `{ clientId?, clientSecret?, scopes? }` object (was flat `settings.oauthClientId` / `oauthClientSecret` / `oauthScopes`) - `metadata`, `connectionTimeout`, `requestTimeout` move to the entry's top level as-is (Inspector-only fields) The in-memory + wire shape is unchanged from #1352: `InspectorServerSettings` keeps pair-array `headers` and flat `oauth*` fields because the form needs them in that shape to drive controlled-component editing. The bidirectional conversion lives in `serverList.ts` (`storedFieldsToInspectorSettings` / `inspectorSettingsToStoredFields`) and is invoked by `mcpConfigToServerEntries` / `serverEntriesToMcpConfig` and by the server route's `buildStoredEntry`. The `PUT /api/servers/:id` wire envelope keeps the preserve/clear/apply semantics from #1353 — the backend splats validated `settings.*` onto top-level disk keys when assembling the next on-disk shape. Hard-cutover migration per the issue's decision 4: files written by the one pre-#1358 v2/main build have a nested `settings` block; we drop the node on read with a one-line warn including the server id. The persisted headers / metadata / timeouts / OAuth credentials are intentionally lost on first read — users re-enter them via the form (or hand-edit the file into the flat shape). v2 has not shipped a stable release with the nested shape, so the blast radius is dogfooders only. The smuggle-guard in `buildStoredEntry` widens from just `settings` to all six Inspector-extension keys (`settings`, `headers`, `metadata`, `connectionTimeout`, `requestTimeout`, `oauth`), so a caller can't bypass `validateSettings` by nesting any of them inside `config`. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(servers): address PR review on flatten (#1359) - Single-source the Inspector-extension key list with `satisfies` (finding 1). `INSPECTOR_FIELD_KEY_MAP satisfies Record<keyof StoredInspectorFields, true>` in serverList.ts means a new field on the type forces a compile error here. The set is exported and re-used by the server route's smuggle guard, so adding `proxy` or similar in the future updates all three sites in lockstep. The PUT preserve path now uses a new `stripInspectorFields` helper that derives from the same source instead of hand-destructuring. - Add read-path shape validation in `normalizeMcpServers` (finding 2): `headers: "oops"` / `metadata: 42` / `oauth: []` / non-numeric timeouts are dropped individually with a warn, so a hand-edited malformed file can't put garbage rows into the form. Mirrors the write-side `validateSettings` symmetry. New integration test covers each malformed shape with a partial fixture so a single bad key doesn't take out the whole entry. - Align new warns to the `fileLogger || console.warn` fallback pattern (finding 3) via a small `logWarn` helper, so the legacy-drop and smuggle warns are visible in `npm run dev` where the logger is often unconfigured. - Spec doc tweak: the CLI/TUI out-of-scope note's "writes to `settings.headers`" reference now reads "writes to the entry's top-level `headers` field on disk (post-#1358 flat shape)" (finding 4). Avoids confusion for future readers. - Nits: replace `current.mcpServers[originalId]!` with explicit narrowing; add a comment on the OAuth truthiness drop in `storedFieldsToInspectorSettings` mirroring the write-side comment.

Hand-edited `connectionTimeout: Infinity` would have passed the prior check and propagated to the form. - Add a one-line comment in `normalizeMcpServers` noting that the per-entry object is mutated in place via the `delete` calls — safe for today's callers (freshly parsed JSON, no other reference held) but worth flagging for the next reader (finding A). Skipping findings B (move type guards to module scope — single call site) and C (`isOauthObject` lenient on extra keys — reviewer confirmed this is the intended forward-compat behavior, matching `normalizeServerType`'s unknown-key passthrough).

Cliff Hall	5f9bfdc490	feat(servers): hot-reload server list on external mcp.json edits (#1345) (#1357) ... * feat(servers): hot-reload server list on external mcp.json edits (#1345) Watch ~/.mcp-inspector/mcp.json from the backend and push a change event on a new /api/servers/events SSE channel. The web client subscribes via fetch + ReadableStream (so the existing bearer-auth contract is preserved — EventSource can't send custom headers) and re-fetches on each event. The watcher is lazy: it starts on the first SSE subscriber and stops when the last one disconnects, so tests that never open the channel don't spin up a real fs watcher. Self-fires from the backend's own POST/PUT/DELETE are suppressed by capturing the post-write mtime and comparing it on each watcher event. Chokidar is used for cross-platform editor-save semantics (temp-file + rename produces unlink+add sequences that bare fs.watch handles poorly on macOS/Linux); awaitWriteFinish coalesces those into a single event. createRemoteApp now returns a close() to release the watcher, which the standalone server and the vite dev plugin chain into their existing close paths. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(servers): address PR review on hot-reload (#1357) - writeMcpAndTrackMtime now stat()s the file before writing; if the mtime differs from the last value we recorded, an external editor slipped in between our writes and chokidar would coalesce both into one event whose mtime matches our own write — broadcast directly so peer subscribers learn about the external edit (review finding 1, 5). - Split useServers.refresh into a public refresh() (loading toggle) and an internal refreshInternal(background) the SSE handler calls; the list now stays visible during background refreshes instead of flashing skeleton state on every external mcp.json edit (finding 2). - Coalesce multiple \n\n frames landing in one decode chunk to a single refresh call so back-to-back broadcasts don't race two concurrent GETs whose setState order is unspecified (finding 3). - Clarify createRemoteApp's close() docblock about in-flight SSE stream callbacks (finding 7). - Add integration coverage for PUT/DELETE self-suppression and for the external-edit-between-backend-writes broadcast (finding 6). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(servers): address pass-2 review on hot-reload (#1357) - Clarify writeMcpAndTrackMtime comment so a future reader can't mistake the broadcast for a content-preservation guarantee: the external edit's content may already have been read-around and overwritten depending on the interleave with readMcpConfig. - Drop the no-op GET in the PUT/DELETE self-suppression tests. The pre-stat branch is short-circuited by `lastWrittenMtimeMs === null` with or without it; matches the POST test's structure. - Add explicit no-flicker regression test: tracks every `loading` value across renders during an SSE-driven refresh and asserts none flipped back to true.

Cliff Hall	85a4b4c057	feat(servers): persist per-server settings to mcp.json (#1352) (#1353) ... * feat(servers): persist per-server settings to mcp.json (#1352) - Add optional `settings` node alongside the transport config in each `~/.mcp-inspector/mcp.json` entry. Round-trips through `mcpConfigToServerEntries` / `serverEntriesToMcpConfig` and the `/api/servers` POST/PUT routes. - Drop `MCPServerConfig.headers` from `SseServerConfig` / `StreamableHttpServerConfig` and remove the headers textarea from `ServerConfigModal`. Custom headers are now entered only in `ServerSettingsForm` and reach the wire via `settings.headers`. - Wire `ServerSettingsModal` into `App.tsx`; saves dispatch through a new `useServers.updateServerSettings` mutator. `updateServer` carries the existing settings across config-only saves so they aren't dropped. - Apply settings on the *first* outbound request after a server loads — no need to open the settings form first: - `settings.headers` → SSE / streamable-http wire headers. - `settings.metadata` → `InspectorClientOptions.defaultMetadata`, merged into every outgoing `_meta` (call-time keys win). - `settings.requestTimeout` → `InspectorClientOptions.timeout`. - `settings.connectionTimeout` → Promise.race wrapper around connect(). - `settings.oauth*` → pre-seeded OAuth client credentials. - `RemoteConnectRequest` carries `settings` so the remote backend can source transport headers from the same source as the local path. - `oauthClientSecret` is persisted in `mcp.json` alongside stdio `env` values, both protected by the file's `0o600` permission. - Update `specification/v2_servers_file.md` with the new shape and the removal of the legacy headers field. Tests: round-trip in `serverList.test.ts`; persistence on POST/PUT in `servers-route.test.ts`; first-connect header injection in `transport.test.ts`; `defaultMetadata` merging in `inspectorClient.test.ts`; `useServers.updateServerSettings` + `updateServer` settings-preservation in `useServers.test.tsx`. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(servers): rebuild InspectorClient on every connect so settings refresh The previous onToggleConnection branch reused the existing InspectorClient on a same-server reconnect, which froze settings at the moment the client was first constructed. Editing headers, metadata, timeouts, or OAuth credentials in the settings form was therefore invisible until the user either switched servers or reloaded the page — surprising right after a visible save. Always call setupClientForServer on (re)connect so the latest target.settings flow through to the transport's headers / requestInit, to defaultMetadata, and to the OAuth manager. Also adds remoteClientTransport tests that pin the wire-level contract: settings round-trip through the /api/mcp/connect body when supplied, and the field is omitted when no settings are configured. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(history): stop wiping pendingRequestEntries inside the connect event State managers (ManagedToolsState, ManagedPromptsState, ManagedResourcesState, ManagedResourceTemplatesState, ManagedRequestorTasksState) handle the client's "connect" event by calling `void this.refresh()`. The synchronous portion of refresh runs through SDK Protocol.request → transport.send → MessageTrackingTransport.send → trackRequest, all before yielding to the network — so each list request gets tracked into MessageLogState's pendingRequestEntries inside the same connect event dispatch. MessageLogState's own "connect" listener was registered after those state managers (it's the last one constructed in App.tsx) and cleared pendingRequestEntries on every connect. Listener order meant the clear ran *after* the requests were tracked but before their responses arrived, leaving the history with unmatched "response" entries marked PENDING. The clear-on-disconnect (via statusChange → disconnected) already handles session-boundary cleanup, so clear-on-connect was purely defensive and now actively harmful. Drop the connect listener; keep the disconnect path. Tests: updated the unit test to assert the new behavior (connect does not clear); added an integration regression that wires a sibling connect listener firing listTools and asserts the response folds into the request entry instead of appearing as an orphan. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * chore: drop accidentally tracked debugging screenshot pending-requests.png was a local debugging artifact attached to a conversation, not source. Remove it from the tree (the working copy is kept so the user still has it locally) and rely on the existing untracked behavior going forward. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * test(servers): add e2e check that settings.headers reach upstream MCP Stitches the full v2 pipeline together in one assertion: browser-style RemoteClientTransport → POST /api/mcp/connect (settings in body) → backend createTransportNode applies settings.headers to requestInit → SDK StreamableHTTPClientTransport → upstream MCP test server Captures the upstream HTTP request via FetchRequestLogState and asserts both `X-Tenant` and `X-Trace` are present on the outbound POST. Catches any regression that breaks the wire between the form and the upstream server in a single integration test, instead of the previous coverage which exercised each hop in isolation. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(ServerSettingsModal): invert ListToggle compact prop so icon matches state ListToggle's `compact` prop represents the list's *current* compact state: true means "currently compact" and renders the expand icon to advertise the action (open up). The settings modal was passing `compact={allExpanded}` — exactly inverted. When all sections were open it showed the expand icon (suggesting "open more") and when collapsed it showed the collapse icon, opposite of every other ListToggle caller in the app. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * style(HistoryListPanel): match ServerListScreen Export button — rename + default variant Renames "Export JSON" to "Export" and switches from the subtle ToolbarButton to the same `Button variant="default"` used by ServerListControls so the two Export affordances look identical across screens. Also moves the button to the right of the ListToggle (mirroring the order on the server list screen) and disables it when there are no entries to export. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * style(HistoryListPanel): move Clear button to top toolbar, match Export style Moves the Clear affordance out of the "History (N)" section header and up to the panel toolbar alongside Export, where it now uses the same `Button variant="default"` styling. Order in the toolbar is now: ListToggle · Clear · Export. Clear is disabled when there are no unpinned entries to remove (pinned entries are intentionally preserved). ToolbarButton helper is unused after this change and dropped. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * chore: ignore local debugging screenshots at repo root Stops `git add -A` from re-staging the `*.png` files Claude Code drops at the repo root from attached conversation screenshots. The pattern only matches the top-level (`/*.png`) so legitimate image assets in subdirectories (e.g. `clients/web/public/`) still get tracked when explicitly added.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * style(LogStreamPanel): match HistoryListPanel button styling Clear / Export / Copy All on the Logging screen were rendered with the subtle ToolbarButton helper while History's equivalents use `Button variant="default"`. Switch all three to the default variant so the toolbars look identical across screens and mirror the disabling behavior — each button is now disabled when `entries.length === 0`. ToolbarButton helper is unused after this change and dropped. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(servers): address PR review — debounce save, preserve-on-omit PUT, validate shape, lift connect timeout Round-up of fixes from https://github.com/modelcontextprotocol/inspector/pull/1353#issuecomment-4526861959: 1. ServerSettingsModal saves were firing on every keystroke (one PUT + full mcp.json refresh per character). App.tsx now debounces by 300ms and flushes on modal close so a burst of edits coalesces into one PUT and the form value can't flicker back mid-typing. 2. `PUT /api/servers/:id` with an omitted `settings` field used to silently wipe the persisted settings node. The route now treats the three intents distinctly: - field omitted → preserve existing on-disk settings - explicit null → clear the settings node - settings object → validate + apply `useServers.updateServer` is simplified to drop the client-side carry-through hack, and the test that documented the broken behavior is flipped + augmented with explicit-clear and bad-shape cases. 3. `connectionTimeout` Promise.race is moved from App.tsx into `InspectorClient.connect()`, reading `this.serverSettings?.connectionTimeout`. TUI/CLI consumers now get the same behavior; on timeout the client internally disconnects so the next connect starts clean. 4. Custom Headers hint in `ServerSettingsForm` notes that `Authorization` is owned by the OAuth flow when OAuth is configured — avoids the sharp edge where the SDK's authProvider silently overwrites a user-set Authorization header. 5. New `validateSettings` on the server route rejects malformed shapes (`settings: []`, `settings.headers: "oops"`, non-numeric timeouts, etc.) with 400 instead of letting them persist and crash the UI. 7 (nit). Renamed `settings` → `savedSettings` inside `setupClientForServer` so the variable holding the persisted settings doesn't shadow the later locally-derived values. Follow-ups opened separately: #1356 — Move oauthClientSecret out of mcp.json into the OS keychain (review #6). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(servers): address PR review pass 2 — connect-timeout test, unmount cleanup, tagged intent, lenient settings read Pass-2 review at https://github.com/modelcontextprotocol/inspector/pull/1353#issuecomment-4527089705: (a) New integration test pins the new client-layer connect-timeout contract: a hanging stub transport with `connectionTimeout: 50` rejects with the descriptive error and lands the client in "error" status. Documents what TUI/CLI consumers should expect from the lifted Promise.race in InspectorClient.connect(). (b) useEffect cleanup clears `pendingSettingsTimerRef` on unmount so a route change or HMR mid-debounce can't fire one stale PUT against an unmounted component. (c) Refactor the PUT-route `settingsIntent` discriminator from `"preserve" | "clear" | { value }` to a tagged union with `kind`, and consume it with a `switch` for exhaustiveness — reads cleaner and makes adding a fourth intent painless. (d) `normalizeMcpServers` now runs `validateSettings` on the on-disk settings node and silently strips it if invalid, mirroring the existing lenient-on-read pattern from `normalizeServerType`. Closes the read/write asymmetry where a hand-edited malformed `settings` could survive on disk and get carried through preserve-on-PUT. New route test pins the strip-on-GET + no-propagate-on-preserve-PUT behavior. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(servers): pass-3 review — patch-style PUT, toast on close-flush fail Pass-3 review at https://github.com/modelcontextprotocol/inspector/pull/1353#issuecomment-4529276897. (b) `PUT /api/servers/:id` now treats both `config` and `settings` as optional patches: - field omitted → preserve the on-disk value - explicit body value → apply - settings: null → clear `updateServerSettings` stops reading `existing.config` from the in-memory `servers` snapshot, which closes the closure-capture hazard where a refresh between debounce-schedule and flush could silently revert a separate edit. The route is the single source of truth for transport config now. New tests cover settings-only PUT, rejected non-object config, and the empty-body no-op patch case. The previous "rejects a missing config" test is rewritten to document the new no-op-preserve semantics. (c) Inline comment near the PUT rebuild loop documents that writing the full mcpServers map back is what gives the route its desirable self-healing property for malformed settings on *other* entries — deliberate side-effect, not an accident of normalization. (d) `flushPendingSettings` surfaces failures via @mantine/notifications instead of swallowing them. The modal already closed by the time the flush PUT resolves, so a silent fail would leave the user thinking their last edits saved (especially painful for the OAuth client secret). The notifications wiring was already mounted in main.tsx. Pass-3 (a) — settings form being effectively uncontrolled mid-edit — is acknowledged in the reply: working as intended today; the proper fix is internal modal state when file-watching (#1345) forces the issue. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(servers): pass-4 review — strip smuggled settings out of config Pass-4 review at https://github.com/modelcontextprotocol/inspector/pull/1353#issuecomment-4529861349. Main finding: `normalizeServerType` spreads unknown keys, so a body that nested `settings` inside `config` would smuggle a settings field onto the stored entry without ever passing through `validateSettings`. Strip the settings key off the incoming config in `buildStoredEntry` so `validateSettings` remains the single write path for the settings node — the "one source of truth" invariant pass 2 set up holds again. Two new tests pin the strip on both routes: - POST with `config.settings = { bogus }` lands an entry with no settings node on disk. - PUT with `config.settings = { bogus }` + `settings: null` clears the real settings *and* doesn't re-attach the bogus payload via the spread. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(servers): pass-5 review — absorb late connect rejection, tighten validateSettings, log smuggle warning Pass-5 review at https://github.com/modelcontextprotocol/inspector/pull/1353#issuecomment-4529954490. Main finding: when the connect-time `Promise.race` lost to the timeout, the original `this.client.connect(this.transport)` promise was left pending. After `disconnect()` tore the transport down, real transports (SSE / streamable-http) would reject that promise later — with no handler attached, producing a Node `unhandledRejection` (and a vitest suite warning). Attach a no-op `.catch` right after creating the connect promise so Node sees the late rejection as handled. Nit (a): `validateSettings` was casting the raw object through to `InspectorServerSettings`, which let unknown keys ride along onto disk. Replaced the cast with an explicit pick-and-build over the known fields. Unknown stowaways now silently drop on the way through. New route test pins the behavior. Nit (b): `buildStoredEntry` now logs a `warn` via the route's pino logger when an incoming `config` carries a `settings` key. The strip is still defensive (it isn't a documented contract) but the warning lets a misconfigured client find out about the wasted field instead of debugging a silent drop. Nit (c) — the defensive `?? {}` fallback in `buildStoredEntry` — acknowledged in the review reply; left in place as belt-and-braces. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(servers): pass-6 polish — scope absorber, thread id, drop empty OAuth, guard `in` Pass-6 review at https://github.com/modelcontextprotocol/inspector/pull/1353#issuecomment-4529979135. Reviewer signed off as ready; landing the four marginal cleanups since they're all small. (a) `connectPromise.catch(() => {})` moves inside the `if (connectTimeoutMs > 0)` branch. The await-only path propagates rejection cleanly through the outer try/catch — the absorber is only needed when the race leaves the original promise unattended. Code now reads as "absorber is tied to the race," which is the real invariant. (b) Thread `id` (POST id, PUT newId) through `buildStoredEntry` and include it in the smuggle warning's pino bindings. Two clients smuggling simultaneously are distinguishable in the log instead of indistinguishable. (c) `validateSettings` coerces empty-string OAuth fields to absent. The form emits `""` when the user clears an input, and an empty `oauthClientId` on disk would later be misread as "OAuth configured." New route test pins it. (d) `buildStoredEntry` adds a null/object guard before `"settings" in configObj`. The route layer pre-checks this on POST and PUT, but the helper's `unknown` parameter is a weak contract; the guard makes it safe to call from anywhere. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(spec): reflect settings persistence + patch-PUT contract in v2_servers_file The doc was authored when `mcp.json` only stored the server list. Bring it forward to match what shipped in #1352 / PR #1353: - Summary calls out that the file also stores per-server settings and links into the Per-server settings section. - On-disk format note explains that `settings` is an optional Inspector- specific extension that other MCP tools ignore. - New top paragraph on the Per-server settings section explains the basic-config / settings UI split rationale (simpler form for the common case, advanced settings tucked behind a second dialog). - UI bullet is rewritten to match the patch-style PUT semantics that emerged across the review cycle: settings-only and config-only PUTs preserve their counterpart inside the write lock, so neither modal can silently clobber the other half. The earlier "must re-send settings on PUT" hack is gone. - New bullets capture the save cadence (300ms debounce + flush-on-close + failure toast), the patch-PUT contract (omit-preserve / null-clear / rename), and the write-path / read-path validator gates. - Secret storage bullet links to #1356 (OS-keychain follow-up). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(spec): show a third entry with the optional settings node The On-disk format example demonstrated only basic stdio entries. Add a streamable-http entry with a populated `settings` node so readers can see the shape inline rather than having to scroll to the Per-server settings section. Inline comment in the block cross-links there for the full contract and notes that other MCP tools ignore the extension key.

Full CRUD round-trips through new /api/servers routes; first launch writes the two existing seeds if the file is absent. Backend (core): - store-io: getDefaultMcpConfigPath() — sibling of getDefaultStorageDir() - core/mcp/serverList.ts: pure converters MCPConfig <-> ServerEntry[], DEFAULT_SEED_CONFIG, and normalizeServerType (moved from node/config.ts to keep serverList.ts Node-free) - core/mcp/remote/node/server.ts: GET/POST/PUT/:id/DELETE/:id /api/servers routes, plus RemoteServerOptions.mcpConfigPath defaulting to getDefaultMcpConfigPath(). Ids validated with validateStoreId. Frontend: - core/react/useServers.ts: { servers, loading, error, refresh, addServer, updateServer, removeServer } over the new endpoints - App.tsx: drops SEED_SERVERS, wires useServers, disconnects on remove of the active server, follows id on rename of the active server - ServerConfigModal: Add/Edit/Clone form (stdio: command/args/env/cwd; sse/streamable-http: url/headers as one-per-line text) - ServerRemoveConfirmModal: confirm-on-remove with id + transport summary Tests (52 new): - unit: getDefaultMcpConfigPath env-var permutations, serverList round-trip, hook flows against real Hono app.fetch (no TCP), modal forms + validation - integration: /api/servers routes against a real createRemoteApp + tmp file - stories with play functions for both new modals Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(servers): address PR #1349 review (correctness + nits) Bugs: - normalizeServerType: validate against the allowed set and default unknown / non-string types to "stdio" (matches the missing-type case). Prevents a hand-edited {"type":"websocket"} from leaking past `as ServerType` and surprising downstream narrowing. - onConfirmRemove: when removing the active server, also destroy() the 9 state managers and null them + the client out so they GC immediately instead of waiting for the next server switch. - /api/servers mutating routes: serialize POST/PUT/DELETE through an in-process write-lock so concurrent read-modify-write cycles can't lose updates. New integration test fires 25 parallel POSTs and asserts every entry lands. - readMcpConfig comment: update to match actual behavior (valid-JSON file with no `mcpServers` → empty; invalid JSON → 500 from the outer try, so corruption surfaces rather than silently emptying the list). New integration tests pin the 500 path on both GET and POST. Nits: - Add --inspector-surface-subtle token, use it in ServerRemoveConfirmModal instead of the raw Mantine var. - Rename useServers buildHeaders boolean param to includeJsonBody. - Add a comment on the env-value vs header-value trim asymmetry (env values preserve trailing whitespace; header values follow RFC 7230).

The queued event drains when the consumer eventually arrives. 2. /api/mcp/connect's transport.onclose handler no longer deletes the session immediately when no consumer is attached. Instead it holds the session (with queued stderr + transport_error) for a 30s grace window so the events endpoint can drain it. A timeout sweeps if no consumer ever connects. 3. /api/mcp/events detects isTransportDead after attaching the consumer (which just drained the queue), yields once to flush, then closes the stream and deletes the session. End result: the user sees the actual error (e.g. "Cannot find module" from stderr + the transport-closed reason) instead of a confusing 404. Tests: - New unit tests (clients/web/src/test/integration/mcp/remote/remote-session.test.ts) cover the queueing behavior, live delivery, and clearEventConsumer signaling under all transport-state permutations. - New integration test (connect-crash.test.ts) spawns a node subprocess that writes to stderr and exits, then verifies the events stream delivers both the stderr line and the transport_error event before closing — the exact scenario from PR #1349.

Servers that don't advertise the `tasks` capability (the common case) reply with -32601 "Method not found", which then surfaces in the inspector's console for every connect. Skip the call when the server doesn't declare `tasks` — empty tasks list is the right semantics. Existing tests opt into capabilities so the live-path coverage is preserved; two new tests pin the gated behavior (direct refresh + connect-event-triggered refresh).

Subscribe to InspectorClient's `disconnect` event and clear activeServerId there. Covers all three disconnect paths uniformly: - user toggles the connected card off - user clicks the header Disconnect button - mid-session transport failure (subprocess exit / network drop) Event-based instead of effect-based on connectionStatus to avoid the first-render-clobbers-new-id trap (status starts as "disconnected" for a freshly-created client before connect() runs).

Cliff Hall	02182e3b6c	test(core): backfill coverage on inspectorClient + remote server (#1317) ... * test(core): backfill coverage on inspectorClient + remote server Resolves #1310. Drops the two TODO(#1310) exclusions from clients/web/vite.config.ts (coverage.exclude); both files now pass the per-file gate (lines >=90, statements >=85, functions >=80, branches >=50). core/mcp/remote/node/server.ts (88.15 / 78.37 -> 97.29 / 100): - Extract createTokenAuthProvider to its own file (core/mcp/remote/node/tokenAuthProvider.ts) so the 7 no-op OAuthClientProvider stubs can be unit-tested directly. - Add focused integration tests covering the remaining gaps: * createTransportNode failure path on POST /api/mcp/connect * /api/mcp/send when transport is dead * /api/log non-JSON body (catch fallback) * forwardLogEvent unknown-level / no-messages / string-first-message fallbacks (lines 232, 240-242, 257-265 in the original) * /api/fetch missing-url + upstream-throw paths * /api/storage POST invalid storeId + invalid JSON body * /api/storage GET when the on-disk store is unparseable core/mcp/inspectorClient.ts (73.48 / 72.09 -> 91.16 / 89.92): Added a single "Coverage backfill (#1310)" describe block to the existing integration test, plus a few unit-style cases: - OAuth getters / setOAuthConfig / authenticate when oauthManager is unset. - Simple session, roots, subscription, and instructions accessors. - subscribe / unsubscribe error paths against a server without the subscribe capability; happy path against one with it. - getPrompt + readResourceFromTemplate happy path + expansion-failure. - setLoggingLevel "Server does not support logging" guard. - getAppRendererClient (null before connect, cached proxy after). - OAuth + stdio: authenticate() throws via getServerUrl()'s stdio check. - listChanged notifications: tools/resources/prompts handlers via the fixture add_tool / add_resource / add_prompt tools. - Misc tiny branches: re-connect no-op, elicit form mode, getTaskCapabilities on a tasks-less server, receiver-task TTL cleanup + cancel via the private surface (the focused-unit pass the issue describes). - defensive `if (!this.client) throw` guards: one nullify-and-call test exercises 16 of them via a single instance, plus the connect() entry guard. The receiver-task internals test uses (instance as unknown as { private fields... }) to drive createReceiverTask / cancelReceiverTask / TTL cleanup directly; per the issue, refactoring private helpers to be testable from a unit test was authorized. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * test(core): address #1317 PR review feedback - Rename the misnamed "listChanged notifications" describe in inspectorClient.test.ts to "capability detection after connect", since the test asserts only on getCapabilities() round-tripping and never triggers or observes a notification dispatch. Real dispatch coverage lives in the adjacent "list_changed + resourceUpdated notifications" block. Kept the resources/prompts fixtures with a note explaining why they are required for the server to advertise the matching capabilities. - Expand the comment on the 250ms wait in remote-transport.test.ts' /api/mcp/send dead-transport test so it is clear the >= 500 assertion is intentionally permissive across both the dead-transport short- circuit and the downstream send-failure branches. - Add a "keep this in sync" pointer on the nullify() helper so a future cleanup that removes any of the defensive `if (!this.client) throw` guards in inspectorClient.ts is reminded to drop the matching call here rather than silently under-covering.

Cliff Hall	82269e78cb	refactor(core): apply v1.5-port cleanups deferred from #1306 (#1316) ... * refactor(core): apply v1.5-port cleanups deferred from #1306 Addresses issue #1309 — five small, mechanical cleanups deferred from the v1.5 runtime port: 1. Collapse BrowserOAuthStorage / NodeOAuthStorage / RemoteOAuthStorage onto a shared OAuthStorageBase. Three ~130-line duplicates become thin adapter wrappers; behavior + public API unchanged. 2. Re-enable erasableSyntaxOnly in tsconfig.app.json by rewriting the seven (plus two the issue missed in sampling/elicitation create- message) parameter-property constructors as explicit field + assign. 3. Route the lone console.error in inspectorClient.ts through this.logger. 4. Replace `${Date.now()}-${Math.random()}` with crypto.randomUUID() at the five local-only ID sites (message tracking + sampling/elicit). 5. Pin the remote-server hono app generic at new Hono<Env>() and drop the streamSSE cast. Root cause of the cast was an unresolved hono subpath: the tsconfig "hono/*" wildcard didn't honor the exports map, so hono/streaming leaked to the root-hoisted hono@4.12.12 while hono itself resolved to clients/web/hono@4.12.18. Replaced the wildcard with an explicit hono/streaming entry in both tsconfig.app and tsconfig.test, removing the package-identity mismatch. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * refactor(core): address #1316 PR review feedback - Drop the stranded no-op getServerState() read at the top of clearClientInformation in OAuthStorageBase (carried over verbatim from the three originals). - Drop the crypto.randomUUID() guard at the task-ID site so all six in-scope sites are consistent; the fallback branch was dead code on every supported runtime. - Remove the residual `c as Context` cast at the streamSSE call site in core/mcp/remote/node/server.ts — once both hono imports resolve to the same package the route-typed Context flows through to streamSSE with no cast at all. - Move the new `options` / `config` field declarations in RemoteClientTransport up with the rest of the field block, matching the layout used by the other five rewritten classes in this PR.

Files copied verbatim from origin/v1.5/main via `git show >`; only minimal adapters added on the v2 side. Subsystems landed ----------------- - core/logging/, core/storage/, core/auth/ (browser + node + remote) - core/mcp/ runtime: inspectorClient.ts (2169 LOC), oauthManager, messageTrackingTransport, fetchTracking, config, index - core/mcp/node/ (stdio transport) - core/mcp/remote/ + remote/node/ (HTTP/SSE transport + Hono server) - test-servers/ package (composable MCP test servers, fixtures, harness) v2 adapter layer ---------------- - types.ts: append CreateTransport*, AppRendererClient, InspectorClient{Environment,Options} (v2 had pruned these — v1.5 needs them) - samplingCreateMessage / elicitationCreateMessage: keep v1.5 classes AND v2's Inspector Pending* interfaces in the same files - inspectorClientEventTarget: add oauth* event keys; switch pending sampling/elicitation payloads to the classes (matches v1.5 contracts) - json/jsonUtils: append convertParameterValue/convertToolParameters/ convertPromptArguments + ParameterSchema - inspectorClient.ts: re-export Options/Environment/Transport* so tests that import these from `inspectorClient.js` keep resolving; replace `../package.json` import with a hardcoded identity (v2 has no core/package.json) - remote/node/server.ts: cast hono Context for streamSSE (hono generic tightened since v1.5) - oauth-callback-server: drop unused hostname field - tsconfig.app.json / tsconfig.test.json: add @types/node + paths for pino/zustand/hono/@hono/node-server/atomically/express/yaml, disable erasableSyntaxOnly (parameter-property syntax from v1.5) - vite.config.ts: regex-form module aliases (so the package's exports field handles subpaths like `hono/streaming`, `zustand/middleware`), alias for @modelcontextprotocol/inspector-test-server → test-servers/src Tests ----- - 19 v1.5 test files copied under clients/web/src/test/core/, imports rewired to @inspector/core/* and @modelcontextprotocol/inspector-test-server - 1004 unit tests pass; 298 storybook tests pass; coverage gate passes Known follow-ups (out-of-scope here, tracked in TODOs) ------------------------------------------------------ - 13 integration test files are excluded from the unit project (spawn real HTTP/stdio servers; run real OAuth flows; mock SDK auth → happy-dom CORS). Needs a node-env vitest project. Files listed under `test.projects[0].test.exclude`. - Source files exercised only by those integration tests are excluded from the coverage gate pending the node-env project. Listed under `test.coverage.exclude` with comment. - Manual smoke tests against real stdio / HTTP / OAuth server per the AC on #1302 still need verification locally. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs/fix: address #1306 review (AGENTS tree, #1307 links, @types/node, .substr) - AGENTS.md: expand the project-structure tree to include all v1.5-ported subsystems (core/auth/{browser,node,remote}, core/storage, core/logging, core/mcp/{node,remote/{,node}}, core/mcp/state) plus the new top-level test-servers/ directory (with a note about its @modelcontextprotocol/ inspector-test-server alias). - vite.config.ts: reference #1307 from both the test exclude block and the coverage exclude block so the next person editing either sees the marching order for shrinking the lists. - package.json: restore @types/node to ^24 (an earlier `npm install --save-dev @types/node@^22` accidentally pinned it lower than the repo was using; nothing here required ^22). - core/mcp/fetchTracking.ts: replace deprecated .substr(2, 9) with .slice(2, 11) to match the convention in core/mcp/inspectorClient.ts.
