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	e2c75da5ce	Extensions: Connection Info both eras + io.modelcontextprotocol/ui advertisement (Phase 3 of #1633) (#1744) ... * Extensions: Connection Info both eras + io.modelcontextprotocol/ui advertisement (Phase 3 of #1633) Completes the Extensions surfacing and advertises the MCP Apps UI extension. core/mcp/extensions.ts: - Add UI_EXTENSION_KEY ("io.modelcontextprotocol/ui") and MCP_APP_MIME_TYPE ("text/html;profile=mcp-app") — mirrors of ext-apps' EXTENSION_ID / RESOURCE_MIME_TYPE (hardcoded: the constants live on the package's /server subpath or an extensionless re-export that doesn't resolve under NodeNext). - Registry entries gain an optional `advertisement` value; the builder stamps it (default {}). Add the `ui` entry, default-advertised with `{ mimeTypes: ["text/html;profile=mcp-app"] }` — the Inspector always renders App tools. No ext-apps cast needed: the extensions value type is `object`. ConnectionInfoContent: - Source server extensions from the negotiated `capabilities.extensions` (getServerCapabilities, era-transparent) instead of the modern-only discoverResult, so a LEGACY server advertising extensions renders them too. - Add a two-column "Server Extensions" / "Advertised Extensions" section (the Inspector's own advertised map), mirroring the server/client capability columns. Drop the now-redundant Extensions row from the modern Discovery section (Supported versions stays). Tests: extensions.test.ts covers the ui entry + advertisement value and the per-extension enable/disable; ConnectionInfoContent.test.tsx covers legacy server extensions (no discovery), the advertised-extensions column, and the em-dash empty states. npm run ci green (the one InspectorView localStorage failure is a known flake, passes on re-run).

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	e70a11360c	Tools: x-mcp-header annotation tooling + -32602 unknown-tool rendering (#1632) (#1735) ... * Tools: x-mcp-header annotation tooling + -32602 unknown-tool rendering (#1632) Card 9/10 of the SDK-v2 + New Spec stack. Adds SEP-2243 `x-mcp-header` tooling to the Tools tab and adjusts result rendering for SDK v2's unknown-tool behavior, and bumps the SDK to 2.0.0-beta.5. - **`core/json/xMcpHeader.ts`**: a faithful port of the SDK's (non-public) `scanXMcpHeaderDeclarations` — validates every SEP-2243 constraint (primitive types incl. `number`, RFC 9110 token, case-insensitive uniqueness, statically-reachable `properties`-only chain) and derives the mirrored `Mcp-Param-{Name}` params for a kept tool. - **Excluded tools**: the SDK silently drops tools with invalid annotations from `tools/list`. InspectorClient now re-lists the RAW (unfiltered) list and scans it to recompute the excluded set with reasons — gated to the modern non-stdio era (matching the SDK's gate), recomputed on every aggregate refresh, surfaced via a new `excludedToolsChange` event + `getExcludedTools()` and `useInspectorClient().excludedTools`. The Tools sidebar lists them struck-through under an "Excluded (SEP-2243)" divider with the reason on hover. - **Mirrored args**: ToolDetailPanel shows a "Mirrored request headers" section listing each arg → `Mcp-Param-{Name}` (with the browser-omits note). - **-32602 rendering**: SDK v2 rejects an unknown-tool call with `-32602` instead of an `isError` result, which previously rendered nothing. New ToolCallErrorPanel renders a thrown tool-call error, with a targeted "Unknown Tool" hint for `-32602`. Adds unit + Storybook + integration coverage (a real modern server with an invalid-header tool fixture) for every path. `npm run ci`-equivalent checks green.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XNdjEPKLG637X8YmhDiEk5 * Respond to review: disambiguate -32602, doc/search nits (#1632) Addresses the review on PR #1735: 1. -32602 "Unknown Tool" mislabel: `-32602` is generic Invalid params, so a known tool called with bad arguments hit the same code and rendered under the definitive "Unknown Tool" heading. Replace `isUnknownToolError` with `classifyToolCallError(code, message)` → "unknown-tool" only when the message names it (not found / unknown tool / …), else "invalid-params" (new "Invalid Parameters" heading + schema hint), else "generic". 2. Double pagination walk: expand the `listAllTools` comment to document that the excluded-tools recompute is a deliberately un-cached second raw walk (doubles list round-trips on modern non-stdio, runs even on a cache-served aggregate) — accepted for a debugging tool, no-op on legacy/stdio. 3. Doc nit: `scanXMcpHeaderDeclarations` no longer claims to visit "$ref targets" — reworded to note `$ref` is never followed (refs resolve into the unreachable `$defs` body). 4. Search nit: the excluded-list filter now matches name AND title, matching the main tools filter.

Scope the not-found/does-not-exist family to require the word "tool" in the same clause (matching the SDK's "Tool <name> not found"); keep "unknown tool" / "no such tool" as standalone unambiguous markers. Adds a tool-less-"does not exist" test asserting it classifies as invalid-params.

This lets the "Invalid Parameters" branch of the tool-call error panel (added in the review response) be exercised live, distinct from the unknown-tool `-32602`. - `SPEC_ERROR_TRIGGERS` gains the `trigger_invalid_params` entry (HTTP 200, in-band -32602) + preset registration. - Enable `injectSpecErrors` on `xmcpheader-modern-http.json` and add the tool. - README + pr-screenshots README document it; adds the live "Invalid Parameters" proof screenshot.

Cliff Hall	2259b1a3e1	Tasks: io.modelcontextprotocol/tasks extension on modern servers (era fork) (#1731) ... * Tasks: modern io.modelcontextprotocol/tasks extension (era fork core) Core + test-server implementation of the SEP-2663 tasks extension for modern (2026-07-28) connections, forked from the legacy 2025-11-25 tasks path. SDK v2 removed all tasks support AND era-gates the tasks/* spec methods out of the modern era on both the client (outbound) and server (inbound) sides, and its codec rejects a resultType:"task" result outright. So the Inspector drives the extension itself: task creation rides tools/call (a modern method) with the resultType:"task" frame rewritten at the transport to a CallToolResult carrying the handle in _meta; tasks/get/update/cancel go over a raw-wire request channel that bypasses the era gate (full modern envelope, string ids, consumed by the transport). input_required tasks reuse the existing pending-request modal via fulfilInputRequests, answered with tasks/update. No tasks/list, no tasks/result. Tab + run-as-task gate on the negotiated extension; the managed task store's refresh re-polls known handles on modern (no server list). Test server serves the extension via an Express interceptor (SDK can't) + a shared poll-driven runtime. Full integration coverage of both eras.

Verified end-to-end in the web UI (remote proxy): create → poll tasks/get → input_required elicitation → tasks/update → inline result, plus the unchanged legacy tasks/list/result flow. Adds proof screenshots.

The pending-request note now distinguishes a modern task round from an MRTR round: a new 'task-input-required' PendingRequestOrigin threads through fulfilInputRequests → the pending-request modal → MrtrOriginNote, which shows 'submitted via a tasks/update request (SEP-2663), not a retry' instead of the MRTR retry copy. 2. The ordinary (non-run-as-task) modern callTool path now auto-polls an unsolicited task handle: attemptToolCall detects the rewritten handle in the result _meta and drives it to termination (get → input_required/update → inline result), dispatching task events so the Tasks tab + toasts track it and the tool result resolves to the task's final result. The poll loop is shared with the streaming path via extracted helpers (submitModernTaskInput / modernTaskTerminalOutcome / modernTaskPollInterval). Refs #1631 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XNdjEPKLG637X8YmhDiEk5 * Tasks modern era: address review (negotiated envelope version, input-round cap, clarifying comment) + fresh smoke screenshots Review of #1731: 1. withModernTaskEnvelope now stamps the NEGOTIATED protocol version (getProtocolVersion() ?? MODERN_PROTOCOL_VERSION) so the envelope matches the MCP-Protocol-Version header instead of a hardcoded constant. 2. A never-completing input_required task is now bounded by MRTR_MAX_ROUNDS in the shared submitModernTaskInput (threaded through both poll loops), so a non-conformant server can't re-prompt the user forever. New modern_loop_task test-server tool + integration test cover the cap. 3. ToolDetailPanel: comment clarifying that per-tool taskSupport:"forbidden" is deliberately ignored on modern (task creation is server-directed under SEP-2663). (The abort-during-poll observation is addressed in the PR reply: the cancel path uses tasks/cancel and disconnect rejects the in-flight raw request, so the poll stops; matches legacy.) Fresh web-UI smoke screenshots (modern connected, task completed, input_required with the corrected tasks/update note, input completed). Refs #1631 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XNdjEPKLG637X8YmhDiEk5 * Tasks modern era: fix uncancelable input-required loop + sticky cancel Two bug fixes reported during manual testing of the tasks era-fork (#1631): 1. A modern task paused at `input_required` (e.g. `modern_loop_task`, which never advances) could not be cancelled: the poll loop blocked on the pending-request modal, so `cancelRequestorTask` sent `tasks/cancel` but the modal kept re-prompting. Now each modern poll loop registers a per-task AbortController (`registerTaskInputAbort`), `cancelRequestorTask` aborts it to reject the pending elicitation and unblock the poll, and the embedded input requests are tagged with their owning task id (`RELATED_TASK_META_KEY`) so the pending-request UI's Cancel action cancels the TASK rather than sending a "cancel" answer the server would re-prompt on. 2. On the legacy server, cancelling a task briefly showed CANCELLED then flipped to COMPLETED when the in-flight tool call resolved. Cancellation is a deliberate terminal decision, so `ManagedRequestorTasksState` now remembers cancelled task ids and ignores any later non-cancelled status update. Also: move the compact task id onto its own line in the embedded monitoring sidebar so the status badge / Cancel Task control don't wrap; DRY the duplicated task poll-interval logic into a shared `taskPollInterval` helper.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XNdjEPKLG637X8YmhDiEk5 * Address re-review: sticky cancel on legacy refresh + App cancel-routing test Re-review of the cancelable-loop / sticky-cancel fix raised two non-blocking hardening items: 1. The legacy tasks/list refresh() rebuilt the list from the server, honoring only dismissedTaskIds — so a cooperative-cancel server that re-lists a user-cancelled task as completed could un-stick the cancel on a manual Refresh. The refresh path now pins a cancelledTaskIds task to "cancelled" (keeping it visible-as-cancelled, matching the live-merge handlers) rather than dropping it. Covered by a new state test. 2. Added an App.test.tsx case locking in the user-facing half of the fix: Cancel on a task-input-required elicitation calls cancelRequestorTask (not respond).

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).

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). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XNdjEPKLG637X8YmhDiEk5 * test-servers: send_notification uses SDK request-scoped log() → spec-faithful modern gating (#1629) The previous fix routed `send_notification` through `extra.sendNotification` (`ctx.mcpReq.notify`), which streams on the modern leg but emits unconditionally — the log showed up even when the client hadn't opted in via the per-request `logLevel`. 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.

Verified with the full `npm run ci` (validate → coverage → smoke → storybook), green across all clients.

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. Verified with the full `npm run ci` (green across all clients). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XNdjEPKLG637X8YmhDiEk5 * web: hide the modern "Log Level per Request" setting on legacy connections (#1629) The per-request log level is meaningless on a legacy server (which uses logging/setLevel), so hide it in Server Settings when the era is legacy: - protocolEra pinned to "legacy" → hidden (no connection needed), or - protocolEra "auto" that negotiated legacy at connect time → hidden. 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`. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XNdjEPKLG637X8YmhDiEk5 * Single-page list pagination: sidebar toggle + server setting (#1721) Delivers the deferred single-page fetch UI: Tools/Resources/Prompts can be loaded one page at a time instead of auto-aggregating every page — a defensive option for servers with very large lists. - New `singlePageLists` server setting (persisted, server-wide), plumbed through ServerConfig/InspectorServerSettings, serverList convert/default, the node + remote settings paths, and the Server Settings form ("Fetch Lists One Page at a Time"). - New `ListPaginationControls` element (a "Single page" switch + "Load next page" button + "N pages loaded" status) rendered in each list sidebar; the toggle edits the setting live (optimistic) and persists it. - The paged state stores (PagedTools/Prompts/ResourcesState) now own loading: they auto-load page 1 on connect in single-page mode and track nextCursor + page count as observable state; the managed stores skip their all-page walk in single-page mode (so nothing is over-fetched) while still lighting the list-changed indicator. `usePaginatedList` selects the display source and pagination controls per mode — pure, no data-loading in React effects. - Refresh is mode-aware: reload page 1 in single-page mode, refetch the whole aggregate otherwise. 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. Tests added for each; npm run coverage green.

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	d552564966	Network: modern Mcp-* headers, new error codes, cancellation-as-abort (#1628) (#1722) ... * Network: modern Mcp-* headers, new error codes, cancellation-as-abort (#1628) Upgrade the Network tab for the modern Streamable HTTP transport (SEP-2243 / SEP-2575): - Recognise and highlight the mirrored headers (Mcp-Method, Mcp-Name, Mcp-Param-*, MCP-Protocol-Version), decode =?base64?…?= sentinel values inline, and cross-check each against the request body so a HeaderMismatch is visible before the server rejects it. - Show the new spec error codes distinctly: -32020 HeaderMismatch, -32021 MissingRequiredClientCapability, -32022 UnsupportedProtocolVersion (with the server-advertised `supported` versions), and modern -32601 MethodNotFound on HTTP 404 (distinguished from a legacy bare 404 by its JSON-RPC body). - Reflect cancellation as a connection abort ("Cancelled") rather than a hard error, per SEP §7.5. - Confirm and document browser-path header mirroring: the SDK builds the Mcp-* headers client-side and the /api/fetch proxy forwards them verbatim (new integration test). New pure util `mcpNetworkHeaders.ts` holds the recognition/decode/classify logic; new `McpErrorBadge` element renders the distinct error chips. The optional raw-request controls (cacheMode bypass/refresh, single-page fetch) are split to #1721 — they are cross-cutting core + feature-tab work beyond the Network tab. Also refreshes the AGENTS.md board Status option-ID table (the Building / MCP Apps Extension columns were removed). Closes #1628 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XNdjEPKLG637X8YmhDiEk5 * Network smoke-test showcase + fix redaction clobbering JSON-RPC error codes Adds a composable "modern-network" showcase server for exercising the #1628 Network-tab work end-to-end, and fixes a real bug the smoke test surfaced. Bug fix (core): the fetch-tracking body redaction masked ANY field named `code` (targeting the OAuth authorization code), including the numeric JSON-RPC `error.code`. That destroyed the field the Network tab classifies the modern spec errors on, so -32020/-32021/-32022/-32601 never rendered against real traffic. Redaction now only masks STRING values of a sensitive field (secrets are always strings; a numeric code is never one). Test-server showcase (test-servers): `modern-network-http.json` serves a `get_weather` tool with an `x-mcp-header: "City"` annotation plus four `trigger_*` tools. A new `transport.modern.injectSpecErrors` flag installs a middleware on the modern leg that answers the triggers with real HTTP status + JSON-RPC error bodies (400/-32020, 400/-32021, 400/-32022 w/ `supported`, 404/-32601), so the Inspector's error rendering can be driven live. Mirroring finding (verified live, comment corrected in createRemoteFetch.ts): the SDK builds the STANDARD mirrored headers (Mcp-Method / Mcp-Name / MCP-Protocol-Version) unconditionally — they reach the server through the web proxy — but gates `Mcp-Param-*` on a non-browser environment (`detectProbeEnvironment() !== "browser"`), so the web client never emits them. An x-mcp-header tool is therefore uncallable from the web client against a strict modern server (it answers -32020); it works from the Node CLI/TUI. The earlier "mirroring works through the proxy" note was corrected.

Render the badge separately from `metaBadges` and place it on the second row, to the right of the URL, so the top row stays readable and the error name shows in full. The full-width layout keeps it in the top-right cluster (where there's room).

Mantine's Badge uppercases label text by default, which flattened them to a hard-to-read run-together string ("UNSUPPORTEDPROTOCOLVERSION"). Set `tt="none"` so the badge shows the spec's own casing with word boundaries intact; short badges (POST, status) keep the default uppercase.

Move it to the start of the second row (the expand-toggle row) so the top row stays readable; the toggle stays at the end (`space-between` only when the badge is present). The compact sidebar already places it on its second row beside the URL.

Make the wide layout match — Replay as the ReplayButton icon at the start of the right-side action cluster (Replay, Pin, Expand) — so the two layouts are consistent. Drops the now-unused SubtleButton constant. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XNdjEPKLG637X8YmhDiEk5 * Move the modern spec-error chip + alert from the Network tab to the Protocol tab The Network tab is focused on the HTTP transaction; the distinct protocol-error taxonomy (-32020/-32021/-32022/-32601) belongs with the protocol messages. So: - ProtocolEntry now renders the McpErrorBadge chip on the top line (right after the direction badge, both layouts) plus an explanatory alert in the expanded detail, classified by JSON-RPC error code via `classifyProtocolSpecError`. - NetworkEntry drops the chip + alert; it keeps the HTTP-level features (status badge, Mcp-* header highlight/sentinel-decode, header/body mismatch marker, cancellation-as-abort). - The SDK delivers -32020/21/22 (HTTP 400) as JSON-RPC error responses, so they reach the Protocol log directly. -32601 (HTTP 404) and other non-enveloped errors are *thrown* — the request stays pending. `enrichProtocolEntries` (App) correlates the Protocol log to the Network log by JSON-RPC id (parsed from the transport fetch's requestBody) and folds the thrown error onto its pending request, so it too appears in Protocol. This is a derived view; the underlying log is not mutated. Verified live against the modern-network showcase: both a -32020 error response and a thrown -32601 render distinctly in the Protocol tab. Follow-up: a "reveal in Network" link on the Protocol alert (cross-tab scroll-to + expand of the correlated HTTP entry).

The explanatory alert still appears in the expanded detail in both layouts.

The expanded Protocol alert now shows a "View the HTTP request in the Network tab" link when the entry has a correlated Network request; clicking it: - correlates the Protocol message to its transport fetch by JSON-RPC id (`revealableMessageIds` gates the link; `correlateFetchEntry` finds the target on click), - clears whatever filter would hide the target (network filterText + category, and the embedded monitorSearch), - switches to the Network view in whichever mode is active — the pinned column (`pinMonitor`) when the sidebar is open, or the full-screen header tab (`onActiveTabChange`) when it's closed, - scrolls the matching NetworkEntry into view and force-expands it. The reveal is a one-shot: a new `revealId` threads NetworkScreen → NetworkStreamPanel → NetworkEntry, where the targeted entry scrolls itself into view (rAF, after `useScrollMemory`'s restore) + expands, then clears the signal via `onRevealComplete`. Verified live in both the pinned-sidebar and closed/full-screen layouts.

A delivered, protocol-only error gets no link, since the raw HTTP entry adds nothing over the alert. - -32020 HeaderMismatch → link (the mirrored headers are the problem) - -32601 MethodNotFound → link (thrown; the 404 response is only in Network) - -32021 MissingRequiredClientCapability → no link (delivered, protocol-only) - -32022 UnsupportedProtocolVersion → no link (supported list is in the alert) Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XNdjEPKLG637X8YmhDiEk5 * Network: cite SEP-2575 for cancellation-as-abort, not the internal doc's §7.5 The cancellation note referenced "(SEP §7.5)", but §7.5 is a section of the internal v2_new_spec_impact.md doc, not a SEP. The behavior — closing the Streamable HTTP request stream is the cancellation signal; notifications/cancelled is stdio-only — is defined in SEP-2575 (stateless-mcp).

Add a flip-back test. - Comment the intentional double-mount of revealId (pinned monitor + full-screen ScreenStage both match; clear is idempotent). - Doc drift after the Network->Protocol relocation: McpErrorBadge + the mcpNetworkHeaders module header now say the spec-error chip lives in Protocol.

Gate the modern -32601 treatment on the correlated fetch actually being a 404 (mirroring classifyMcpSpecError). -32020/-32021/-32022 are SEP-reserved and unaffected. The correlated HTTP status is threaded from InspectorView (new correlatedFetchStatusById) through ProtocolScreen/ProtocolListPanel to ProtocolEntry; when unknown, -32601 falls back to code-only recognition (the thrown-404 path always carries a 404). Badge, alert copy, and link now resolve together, so a plain in-band -32601 falls through to ordinary error rendering.

The prior fix only rejected -32601 when the status was *known* and not 404; an unknown status fell back to code-only recognition. But the thrown-404 path always carries a 404 (folded in from a 404 fetch), so the unknown-status branch is only ever reached by an ordinary in-band -32601 with no correlated 404 — most notably a stdio connection (no HTTP at all) — which then wrongly got the modern MethodNotFound badge and 404-asserting copy. Drop the escape hatch: -32601 is the modern taxonomy only on httpStatus === 404. Nothing intended is lost (the genuine case always has its 404). Update the tests (code-only/undefined -32601 now expects null; add a stdio no-correlated-fetch ProtocolEntry case) and mark the MethodNotFound story with correlatedHttpStatus 404.

Cliff Hall	9b2c188d11	MRTR: drive input_required manually to keep pending-request UX (#1704) (#1719) ... * MRTR: drive input_required manually to keep pending-request UX (#1704) Follow-up to #1627/#1705. Instead of letting the SDK auto-fulfil the modern (2026-07-28) MRTR retry loop, InspectorClient now drives it itself so the Inspector keeps its pending-request UX, owns the loop, and shows era-accurate semantics. Core (core/mcp/inspectorClient.ts): - Construct the SDK Client with `inputRequired: { autoFulfill: false }` (unconditional; a no-op on legacy, which never returns input_required). - New `requestWithInputRequired()` driver: issues the request with `allowInputRequired` + `withInputRequired(schema)`, and while the result is `input_required`, fulfils each embedded request through the SAME pending sampling/elicitation plumbing, then retries the original call with `inputResponses` + the echoed `requestState` on a fresh id, bounded by MRTR_MAX_ROUNDS. - Route tools/call, prompts/get, and resources/read through the driver. - Embedded roots/list is auto-answered from configured roots (no pending UX); decline/cancel is echoed to the server (not treated as an abort); a tool-call abort mid-round settles the pending request and surfaces ToolCallCancelledError. - Extract shared `enqueuePendingSample`/`enqueuePendingElicitation` helpers used by both the legacy inbound handlers and the driver; add a per-request `origin` ("server-request" | "input-required") to the pending wrappers. Web UI: - New `MrtrOriginNote` element shows an "input_required — your answer returns as a retry" note on a modern MRTR round; legacy panels are unchanged. - Thread `origin` App -> PendingClientRequestModal -> the sampling/elicitation panels (and the inline panels). Test servers: new MRTR presets (multi-round, roots, sampling, loop, edge-case param shaping). Integration tests cover the manual round-trip (asserting the pending UI pauses and the retry carries inputResponses + requestState on a new id), multi-round, roots auto-answer, sampling, decline-echoed, maxRounds bound, abort mid-round, and requestState-only/inputRequests-only param shaping.

The shared "declined/cancelled resolves" wording was accurate only for the elicitation case. - callToolWithRetries abort comment: note the between-rounds case — when the abort lands while an MRTR round awaits an embedded pending request there is no in-flight SDK request, so nothing is sent on the wire; the outcome (ToolCallCancelledError, no failed-call record) is identical.

Cliff Hall	73d9b181fe	History: MRTR conversation grouping + modern message vocabulary (#1705) ... * History: MRTR conversation grouping + modern message vocabulary Teach the Protocol/History view the modern (2026-07-28) message vocabulary, correlating it off the frames the transport already captures — no change to how MRTR is driven (manual driving is deferred to #1704). - Correlation helpers in protocolUtils: extractResultType, extractRequestState, extractSubscriptionId, isModernFrame, and groupProtocolEntries — clustering the contiguous rounds of one logical operation (original call -> input_required -> retried call with a new id -> final result) that share a requestState token. - New MrtrConversation group renders that cluster as one expandable unit with a status derived from the final round, reusing ProtocolEntry for each round. - ProtocolEntry: resultType badge (input required / complete), a "modern" frame badge for server/discover, subscriptions/listen, and the acknowledged notification, and a copyable subscriptionId. - ProtocolListPanel folds each section through the grouping pass and shows an era badge in the header. Era is threaded from the negotiated protocolEra (App -> InspectorView -> ProtocolScreen -> panel) and never inferred from frames, respecting the transcript-classification caveat. - Shared EraBadge element (+ eraUtils); ConnectionInfoContent reuses it. - test-servers/configs/modern-mrtr-http.json serves an elicitation tool over the modern leg for eyeballing a real MRTR round-trip. - Pre-bundle @modelcontextprotocol/client in optimizeDeps.include so the Storybook vitest project doesn't re-optimize mid-run once protocolUtils pulls the client barrel into the browser graph.

So the shipped `modern-mrtr-http.json` (and its README claim) were wrong. - Add a genuine MRTR tool preset (`mrtr_confirm` / `createMrtrTool`): its handler returns `inputRequired({ inputRequests: { confirm: elicit(...) } })` on the first call and the final result once the client echoes the answer back on the retry. - Teach the composable test-server to support it: the tool wrapper forwards an `InputRequiredResult` verbatim (instead of coercing it to a CallToolResult), and `toHandlerExtra` surfaces `inputResponses`/`requestState` so a handler can branch between the original call and the retry. - Point `modern-mrtr-http.json` at the new preset; correct the README to describe the real mechanism. - Add an integration test that drives the full round-trip through InspectorClient (auto-fulfilling the embedded elicitation) and asserts the final result is only reachable after the input_required round + retry — regression cover that would have caught the original config bug. Verified live in the browser: the History view renders the round-trip as one grouped "MRTR conversation" (Round 1 input_required → Round 2 complete), keyed by the real requestState, under the Modern era badge.

Errors/pending have no `resultType`, so their status badge still shows. - createMrtrTool: mint a unique `requestState` per original call (closure counter) so two same-action invocations don't fold into one conversation during manual eyeballing. Real SDK tokens are already unique per operation. - ProtocolEntry: align the `MessageEntry` import to the `@inspector/core` alias used by its siblings (was a deep relative path).

The full-width view keeps the bordered surface that sets a conversation apart.

The modern (2026-07-28) leg is stateless — `createMcpHandler` rebuilds the server (and every tool closure) per request — so the previous per-closure counter reset to 0 on every request and every token ended in `:1`, defeating its purpose. A module-level counter survives the per-request factory recreation and increments monotonically across the process, so same-action invocations get distinct tokens and don't fold into one conversation. (Review finding.) - MrtrConversation: revert the embedded borderless/tighter-padding change — per maintainer feedback from manual testing, dropping the border didn't improve the narrow-column visual, so the group keeps its border in all layouts.

Cliff Hall	e06c0a45f7	Add modern-era (2026-07-28) test-server preset (#1700) (#1703) ... * Add modern-era (2026-07-28) test-server preset (#1700) The era-aware connection model (#1626, PR #1697) added per-server `protocolEra` and the era-aware Connection Info UI, but no bundled test server negotiated the modern era — the modern happy path had only unit/Storybook fixtures, no live coverage. Serve the modern (2026-07-28) protocol era from the HTTP test server via the SDK's `createMcpHandler`. A `modern` flag on `ServerConfig` (and a `transport.modern` field in the JSON config) mounts the handler with a dual-era `legacy: "stateless"` fallback by default, or `legacy: "reject"` for modern-only strict serving. The web-standard `fetch` handler reuses the existing `toWebRequest`/`writeWebResponse` conversion, so no new `@modelcontextprotocol/node` dependency is needed. An SDK v2 client negotiating `protocolEra: "auto" | "modern"` now reaches the modern leg end-to-end: `getProtocolEra() === "modern"`, `getNegotiatedProtocolVersion() === "2026-07-28"`, and a populated `getDiscoverResult()`. Verified live in the Inspector — Connection Info shows Era Modern / Session Sessionless / the Discovery section. - Modern serving path + `listen`/`startModernHttp` helpers in test-server-http.ts; modern-leg teardown in stop(). - `modern` config field threaded through load-config/resolve-config with a streamable-http-only validation guard; modern-http.json demo config. - Integration test covering auto/modern negotiation, the dual-era legacy fallback, a modern tools/call, and the strict `legacy: "reject"` rejection.

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	f4fb4b50c9	Forward RFC 9207 iss to the v2 SDK (fixes OAuth + EMA leg 1) ... SDK v2 added RFC 9207 §2.4 authorization-response issuer validation (`validateAuthorizationResponseIssuer` / `IssuerMismatchError`) as a mix-up attack defense. It is strict: when AS metadata advertises `authorization_response_iss_parameter_supported: true` and no `iss` reaches `exchangeAuthorization`/`auth()`, the exchange throws. v1.29.0 had no `iss` parameter and no RFC 9207 validation at all, so dropping the callback `iss` was harmless. The migration swapped in the stricter SDK without feeding it the new input, breaking the authorization-code exchange against any RFC 9207 authorization server (Okta/xaa.dev advertise it): Issuer mismatch in authorization response (RFC 9207): expected "https://idp.xaa.dev", received undefined Found by smoke-testing EMA against live xaa.dev staging; not caught by CI because the mock IdP never advertised the parameter, so the SDK took its lenient path (a missing `iss` is only fatal when advertised). `iss` was dropped in three places, with the plumbing half-built — `oauthManager`/`inspectorClient` already accepted `iss`, but nothing supplied or forwarded it: - `parseOAuthCallbackParams` never extracted `iss` from the callback query - `mcpAuth` never forwarded `options.iss` to SDK `auth()` — its own comment ("forwarded on v2 upgrade; ignored by v1 SDK auth()") predicted this exact gap, so standard OAuth was broken identically, not just EMA - EMA leg 1 (`completeIdpOidcAuthorization`) never passed `iss` to `exchangeAuthorization` Thread `iss` end to end: callback query -> CallbackParams -> resumeAfterOAuth -> completeOAuthFlow -> {mcpAuth | EMA leg 1} -> SDK. The Node callback server and runner carry it for CLI/TUI. Tests: `ema-mock-servers.ts` now advertises `authorization_response_iss_parameter_supported: true` so the mock is at least as strict as real IdPs — with it absent the SDK silently takes the lenient path and a dropped `iss` goes unnoticed. Flipping it made three existing tests reproduce the failure. Adds regression coverage for forwarding and for rejecting a mismatched `iss` before any network call. Verified end to end against live xaa.dev staging: EMA legs 1-3 (IdP SSO -> ID-JAG mint -> resource token) now complete and the MCP session initializes. web 3099, cli 212, tui 274 green.

cliffhall	8a7a38f800	Fix MCP App load regression: translate ext-apps v1 setNotificationHandler API to v2 ... An MCP App (e.g. NightRider's drum-pad) failed to load with "'[object Object]' is not a spec notification method; pass schemas as the second argument to setNotificationHandler()". `@modelcontextprotocol/ext-apps` still peers on SDK v1 and, during the AppBridge connect handshake, subscribes to tools/resources/prompts list_changed with the v1 schema-first API `setNotificationHandler(NotificationSchema, handler)`. SDK v2 requires a method STRING and throws on a schema object — the migration's compat shim covered the types but not this runtime API difference. Fix in the app-renderer client Proxy (`getAppRendererClient`): translate a schema-first `setNotificationHandler` call to v2's method-string form by reading the method literal off the schema's `shape.method.value`; native string-first calls pass through, and an unrecognized first arg falls through to the SDK's clear error rather than being swallowed. Only `setNotificationHandler` needed this — AppBridge's `request(req, schema, …)` calls work as-is (the v1 SDK schemas expose `~standard`, so v2 accepts them). Remove when ext-apps#702 ships a v2 peer. Added an integration test covering the schema-first translation end-to-end (handler fires on a real tools/list_changed), plus the string-passthrough and unrecognized-schema branches. Coverage ≥90 holds; typecheck + App tests green. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-07-15 12:44:20 -04:00
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).

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

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

Narrow the comment to state it is OAuth-backend-only (client.json/mcp.json still resolve from getDefaultStorageDir → HOME) and record why the resolution lives here rather than in getDefaultStorageDir (the default-path constant is evaluated at module load, so a runtime-set MCP_STORAGE_DIR — as the CLI stored-auth / --wait-for-auth flows set it — must be read at call time). Comment-only; no behavior change.

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

Cliff Hall	0ddb79203a	web: Wave 2 — spec-conformant MCP Apps host (rollup of #1565–#1572) (#1660) ... * web: sandbox hardening — opaque-origin inner frame, srcdoc-only, frame-ancestors Harden the MCP Apps sandbox isolation model: - The inner (untrusted-widget) iframe is sandboxed WITHOUT `allow-same-origin` (default "allow-scripts allow-forms") and any server-supplied sandbox value has `allow-same-origin` stripped case-insensitively, so the widget runs under an opaque origin and cannot reach the proxy's DOM to bypass its own CSP via the parent realm. - Widget delivery is `srcdoc`-only (no document.write), which respects the opaque origin. - The relay accepts the inner frame's "null" origin with `event.source === inner.contentWindow` as the unforgeable identity check. - sandbox-controller.ts serves the proxy with `Content-Security-Policy: frame-ancestors http://127.0.0.1:* http://localhost:*`; fetch directives are deliberately omitted so a srcdoc iframe's inherited policy container does not override the per-app CSP. Updated the isolation-model comments and the sandbox-controller integration test asserts the frame-ancestors header (and the absence of fetch directives). Closes #1565 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01BrihGWcrM9JGRyu41nzZYw * web: enforce per-app _meta.ui.csp in the app bridge + surface resource-read failures - createAppBridgeFactory now builds each app's `_meta.ui.csp` host-side via the sandbox-csp library (approveCspSources → buildSandboxCspPolicy) and wraps the untrusted widget HTML with wrapSandboxedHtml so the CSP <meta> is always the first <head> child before the HTML reaches the sandboxed iframe. The approved (post-filter) csp + permissions are echoed back via hostCapabilities.sandbox so the view sees what was granted. The csp is no longer sent inline through sendSandboxResourceReady — it is enforced via the wrapped meta. - A per-app copy of HOST_CAPABILITIES prevents the sandbox echo from mutating the shared constant. - New optional `onResourceError` dep on AppBridgeFactoryDeps routes resource read/post failures to the caller (also always console.error'd) instead of leaving a silent blank frame. Closes #1566 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01BrihGWcrM9JGRyu41nzZYw * web: full hostContext delivery + live host-context-changed updates - createAppBridgeFactory now seeds the full hostContext via snapshotHostContext(iframe, HOST_AVAILABLE_DISPLAY_MODES): theme, styles (Mantine design tokens), displayMode ("inline"), availableDisplayModes, and containerDimensions — replacing the theme-only seed. The local currentTheme helper is dropped in favor of hostContext.ts. - AppRenderer gains `displayMode` and `containerRef` props and pushes live host-context changes via the SDK's sendHostContextChange (partial host-context-changed notifications), never a hand-maintained snapshot: - theme + styles via a MutationObserver on <html data-mantine-color-scheme>, - containerDimensions via a ResizeObserver on the host container (or the iframe fallback), gated on `initialized`, skipping 0x0 and value-equal repeats, plus a one-shot push on initialize once layout settles, - displayMode whenever the prop changes (Maximize/Restore), gated on init. Adds AppRenderer host-context tests (theme flip incl. resolved styles, displayMode push + init gate, container-dimensions on init and resize, observer teardown) and updates the factory + story mocks for the new hostContext shape and sendHostContextChange method.

AppsScreen: - Adds a host-controlled RendererContainer (measured for containerDimensions) with an inner box sized by the view-reported height (`appHeight`), so host→view container size and view→host size-changed don't couple. - `handleSizeChange` records the reported height (ignored while maximized); `displayMode` is derived from the maximize toggle and pushed to the view; `handleRequestDisplayMode` filters against HOST_AVAILABLE_DISPLAY_MODES (declining e.g. "pip") and maps fullscreen↔inline onto the maximize state. Adds AppRenderer tests (size forwarding, request-display-mode apply/decline/ fallback) and AppsScreen tests (frame sizing on report, no-height ignore, fullscreen/restore/decline via request-display-mode). Story mocks gain sendHostContextChange/addEventListener.

Adds factory tests for the full download surface (text/blob/link, decline, empty, throw, non-http rejection, label sanitization/clamping, partial batch).

AppsScreen: - Adds `messages`/`appLogs` state (cleared with the reported height on select/open/close/back via resetAppChannels) and `handleMessage`/`handleLog`. - Renders a "Messages from app" panel (data-testid="apps-messages", reusing ContentViewer) and a default-expanded collapsible "App logs" panel (data-testid="apps-logs", reusing LogLevelBadge) with logger names and a Clear button, both as pinned panels below the running widget. Adds AppRenderer tests (log forward + no-handler no-throw, ui/message route/empty-result/decline) and AppsScreen tests (message log render + empty result + clear-on-close, log panel expand/collapse/clear).

AppsScreen: - New `partialStages` state + `handleStagePartialInput` (snapshots current form values). resetAppChannels gains a `keepPartials` option so Open App preserves the staged fragments (they're consumed by the renderer) while select/close/ back clear them. - Adds a "Stage partial input" control (fielded apps only) with a staged count and "Clear staged", wired to AppRenderer's `partialInputs`. Adds AppRenderer tests (ordered replay before tool-input; none when omitted) and AppsScreen tests (stage/count/clear gated on fields; staged partials survive Open and are replayed).

Fires "loading" at the start of every (re)build, "ready" on the view's initialized signal, and "error" on a factory throw/rejection. AppsScreen: - appStatus/appError state; handleAppError captures the reason locally and forwards to the parent onError. resetAppChannels clears both. - Surfaces the contract as data-testid="apps-form" carrying data-app-status and data-app-error, renders an error panel (data-testid="apps-error") in place of the blank frame, and tags the stage button data-testid="apps-stage". - AppDetailPanel's Open App button gains data-testid="open-app". App.tsx: - Wires the bridge factory's onResourceError to a red toast so a malformed/404 UI resource is no longer console-only (the renderer separately drives data-app-status, so a driver times out on never-reaching-ready and reads it). Documents the data-testid/data-* automation contract in clients/web/README.md. Adds AppRenderer status-transition tests and AppsScreen status/error-panel tests.

The factory seeds the construction-time theme, and the first post-init flip carries the current value. Added tests: pre-init flip is dropped; the live flip test now completes the handshake first. - Finding #2 (applied, comment): note in snapshotHostContext that the `displayMode: "inline"` seed assumes inline-at-open (AppsScreen always opens inline; #1568's displayMode push carries transitions). - Finding #4 (applied, comment): explain why `containerRef` is a build-effect dep yet doesn't force a rebuild (sameInputs ignores it; read lazily).

Added a test. - #2 (applied): reinstate a distinct `RendererFrame` constant for the inner content-sized box so its role reads clearly vs. the outer RendererContainer. - #3 (declined + comment): keep carrying `appHeight` across maximize→restore — clearing it would flash the frame to full-card height until the next size-changed; the carry-over restores at the prior size. Documented. - #4 (applied): type handleSizeChange's param as AppBridgeEventMap["sizechange"] so the payload shape has a single source of truth with AppRenderer's prop.

Reworded the README row and the test comment to say "below the frame"; added a code comment. - #2 (applied): gate data-app-error on `running` (like data-app-status) so the two attributes can't desync if a future path sets an error without running. - #3 (no change): resource-read failures staying at data-app-status="loading" (toast only) is intentional and documented.

cliffhall	a26cbac609	review: harden version read + fix MonitoringScreen docstring ... Address PR #1641 review feedback: - Add readInspectorVersionSafe() (non-throwing) in core/node/version.ts and use it in the web backend, so a failure to resolve the root manifest hides the (cosmetic) version badge instead of crashing the backend at startup. Covered by tests for both the resolved and unresolvable paths. - Update MonitoringScreen's docstrings: it now wraps every supplied screen in a ScreenStage (only the active tab mounts, cross-fading) rather than rendering just the active tab's node.

cliffhall	650e5bd020	feat(web): show the Inspector version in the lower-right corner (#1639) ... 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. Tests: useInspectorVersion (full branch coverage), VersionBadge (unit + Storybook), web-server-config payload.

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

cliffhall	1e6a2825d4	fix(auth): keep oauth-persist browser-safe (move Node file backend out) ... The refactor routed the browser's RemoteOAuthStorage through `oauth-persist.ts`, which value-imported the Node-only `store-io.js` (`atomically` -> `stubborn-fs` -> `node:process.getuid`, plus `node:fs/promises`). That dragged Node built-ins into the browser bundle and the web app crashed to a blank page at runtime — a regression from v2/main, where browser OAuth storage used a Zustand JSON adapter with no Node imports. Unit/integration tests run in node/happy-dom and `smoke:web` only checks the served HTML, so none of them execute the app in a real browser and the break slipped through. Fix, following the existing `store-id.ts` precedent: - Split the pure JSON (de)serializers into Node-free `core/storage/store-serialize.ts`; `store-io.ts` re-exports them so existing importers are unaffected. - Move the Node-only `createFileOAuthPersistBackend` into `core/auth/node/oauth-persist-file.ts`; update `storage-node.ts` and the storage adapters test to import from there. - `oauth-persist.ts` now imports only the Node-free serializers, so the browser bundle no longer pulls in `node:fs`/`atomically`. Tests: - oauth-persist-browser-safe.test.ts: source-level guard that `oauth-persist.ts` never imports store-io/node:/atomically. - Direct unit tests for the isomorphic remote + session backends (restoring oauth-persist.ts coverage after the file backend moved out). - store.test.ts: OAuthMemoryStore unit coverage incl. replace() fallbacks. - storage.test.ts: clearAllOAuthClientState null-snapshot (no file) path. Verified end-to-end in a real browser (Playwright): DCR OAuth flow completes, tokens persist via the remote store, and after a full page reload the server reconnects with no re-authentication.

cliffhall	4bad110942	test(web): eliminate timeout flakiness in the web test suite (closes #1596) ... Root-cause and deterministically fix the recurring 5s-timeout flakes that surfaced under v8-instrumented, concurrent load. All fixes are test-only; no product source changed. No test was skipped or disabled, and the per-file coverage gate (>=90 on all four dims) still holds. Common root cause across the modal/form/screen suites: userEvent.setup() schedules a real setTimeout between keystrokes. Under CPU contention those yields balloon, so multi-field interactions blew past the 5s per-test timeout. Fix: userEvent.setup({ delay: null }) removes the per-keystroke real-timer dependence (typing dispatches synchronously), making the suites load-independent. Per file: - ServerConfigModal / ServerImportConfigModal / ServerImportJsonModal / ResourcesScreen / InspectorView: userEvent.setup({ delay: null }). - PromptArgumentsForm (completions): replaced wall-clock sleeps sized just past the 300ms completion debounce (await setTimeout(400)) — which race the debounce timer under load — with awaited conditions (findBy/waitFor) on the real rendered outcome, plus delay:null. Negative assertions now lean on the component's synchronous state/timer teardown instead of a timed window, so they are deterministic regardless of machine speed. - inspectorClient integration "tracks stderr logs": the child's stderr is piped out-of-band from the tool's JSON-RPC response, so reading the log synchronously after callTool raced the stderr chunk. Wrapped the assertion in vi.waitFor so it polls until the line lands. Verified: web validate + 6x test:coverage (4 sequential + 2 concurrent under load) + standalone test:integration, all green (229 files / 3237 tests per coverage run; 799 integration tests), zero intermittent failures.

cliffhall	c299b6e9d8	feat(web): migrate OAuth store to shared /store API (RemoteOAuthStorage parity) (closes #1548) ... Migrate the web client's OAuth storage from BrowserOAuthStorage (sessionStorage) to RemoteOAuthStorage, which POSTs through the backend's /api/storage/oauth route to ~/.mcp-inspector/storage/oauth.json (mode 0600). A credential obtained in the browser is now the same blob the TUI/CLI read on the same host, giving web ⇄ TUI ⇄ CLI parity (Wave 1 of #1579). Core (shared with TUI/CLI): - OAuthStorageBase now drives a single async hydration (`ready()`, `getHydrationError()`); every post-redirect read (getClientInformation, getTokens, getCodeVerifier, getServerMetadata, getIdpSession) and every save awaits it so a late hydration merge cannot clobber a fresh write. getCodeVerifier/getServerMetadata become async; the store is created with skipHydration:true so there is no auto-hydration to race the explicit one. - store.ts adds normalizeServerUrl so a token saved under https://Example.com/mcp is found when the CLI asks for https://example.com/mcp/; getServerState falls back to the raw key. - remote-storage adapter POSTs with keepalive so the write survives the OAuth authorize redirect, surfaces swallowed persist failures, and gives richer read/write error messages. - generateOAuthState throws instead of silently degrading to Math.random. - NodeOAuthStorage honors MCP_INSPECTOR_OAUTH_STATE_PATH for isolated fixtures. Provider codeVerifier()/getServerMetadata() + the EMA idpOidc and connection-state readers await the now-async storage. Web: - environmentFactory + a new shared lib/remoteOAuthStorage accessor (memoized per {baseUrl, authToken}) wire RemoteOAuthStorage into the connection path, the EMA IdP hook, and the per-server "clear OAuth" action so all three share one in-memory view of oauth.json. Tests: async-hydration + normalizeServerUrl suite, keepalive/error-path coverage, and the sync→async migration across existing storage/provider/EMA tests. Web validate + coverage gate + integration suite green; CLI/TUI/ launcher validate green.

Cliff Hall	c96db0402e	test: raise per-file coverage gate to 90 across all clients (closes #1271) (#1532) ... * test(web): audit branch-coverage outliers, raise per-file gate to 70 (#1271) The web per-file coverage gate had drifted red: the recently-landed EMA auth feature (core/auth/ema/*) and ClientSettings components shipped undertested, and the prior 50% branch floor let business-logic branches go untested. CI does not run the coverage gate, so this accumulated. Add tests to bring every failing file above the gate and push branch coverage well past 70 across the board, then raise the per-file branches threshold 50 -> 70 in clients/web/vite.config.ts. - EMA core (emaFlow, resourceContext, jwt, wire): 50-88% -> 86-100% branch - EMA OIDC/transport (idpOidc, tokenEndpoint, transportProvider): -> 97-100% - oauthManager / discovery: 73-83% -> 88-92% - ClientSettingsModal/Form, ConnectionInfoContent: 0-88% -> 96-100% - useClientSettingsDraft / useEmaIdpLoginState hooks: 20% -> 100% - TaskStatusBadge / SortableServerCard outliers: 50% -> 100% Coverable branches reached by mocking useComputedColorScheme (dark theme), dnd-kit useSortable (isDragging), and fetch/OIDC paths. Remaining sub-100 branches are genuinely-unreachable defensive guards or happy-dom-inherent (portal / useMediaQuery / typeof window) and documented in test comments. No source files changed. Global web branch coverage 88.73% -> 90.63%. AGENTS.md updated; cli/tui/launcher stay at 50 (out of scope). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * test: raise per-file coverage gate to 90/90/90/90 across all clients Follows the #1271 web branch-coverage audit (50 -> 70) by raising the whole per-file gate to >=90 on all four dimensions — lines, statements, functions, branches — for web, cli, tui, and launcher (core/ is measured under the web suite). A codebase-wide audit added real tests for every outlier and brought global coverage up across the board. Config: all four vitest/vite coverage configs set to 90/90/90/90. Two pure-type modules (core/mcp/import/types.ts, clients/web/server/ types.ts) added to the web coverage exclude list, matching the existing type-only exclusions. Tests: ~50 test files extended/created across core (auth, ema, mcp, remote, state, storage, react), web components/screens/server, and the cli/tui clients. Highlights: full EMA OAuth flow + transport coverage, inspectorClient/remote server backfill, every Mantine control's handler branches, and the cli unsupported-method / argv-fallback paths. Genuinely-unreachable branches are annotated at the source with justified `/* v8 ignore -- <reason> */` comments rather than lowering the gate: happy-dom-inherent paths (Mantine portal, useMediaQuery, typeof window SSR guards), React StrictMode effect replay, and provably-dead defensive guards (?? fallbacks the types make impossible, Select.onChange values outside the allowed list). No runtime logic changed; the only structural edits are two behavior-preserving refactors (ResourceTemplatePanel hoists the field value to a local so the ignore applies in JSX; ToolsScreen swaps a ternary for an if) and prettier line-wrapping. Also fixed a flaky real-timer debounce assertion in PromptArgumentsForm (asserted an exact sibling-typing interleaving that raced the 300ms debounce; now asserts the load-bearing fact — a non-empty fire-time sibling capture). AGENTS.md updated to describe the uniform 90 gate and the v8-ignore policy. All four client coverage gates, root validate, storybook (370), and smoke pass. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * test(web): make connect-crash SSE reader stop on the terminal event `readSseEvents` looped until the server closed the stream (`done`). The server closes the events stream immediately after writing the terminal `transport_error`, but under the heavy parallel scheduler pressure of a full `coverage` run (v8 instrumentation across all workers) that close can lag far enough behind the event to trip the 30s test timeout — a hang, not a wrong result. This made the test intermittently fail under `npm run coverage` (it passed in isolation and under CI's lighter `test:integration`). Stop reading as soon as the terminal `transport_error` event arrives (cancelling the reader) instead of waiting only for `done`. That event is always the last one the session queue emits, so nothing is lost, and the test no longer depends on stream-close timing. The `done` break is kept for any stream that closes first. Verified green across two consecutive full `npm run test:coverage` runs (3094 tests) where it previously hung, plus isolation (~0.5s).

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.

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.

Threaded through InspectorView -> ServerListScreen -> ServerCard. - ServerCard scrolls into view on highlight and wraps in <BorderAnimate>; onClick clears the highlight. - Pin @gfazioli/mantine-border-animate@2.0.3 (Mantine 8 compatible; 2.0.4+ requires Mantine 9). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(web): highlighted card fills its cell and its controls work on first click - The BorderAnimate wrapper is display:flex, so the card was shrinking to content width while the border spanned the cell. Stretch the card with w=100% (and the wrapper). - Always render BorderAnimate and toggle show/animate instead of conditionally wrapping: swapping the element type on clear remounted the card, swallowing the click that triggered it (e.g. the connect toggle fired clear but not connect, needing a second click). Verified: one click now connects + clears.

Clarify buildServerConfig (destructure env out instead of spread-then-delete) and document value-vs-default env handling. - useImportClientConfig: validate 'rename' targets inline (invalid charset / collision with existing, additions, or other renames) and gate the Import button on canImport; surface the error on the field.

In a fresh checkout it was absent and the prod path served a broken page (ENOENT on index.html); the launcher smoke test only covered --help, so this path was unverified in CI. - ensure-web-build.ts: build dist on demand (vite build via build:client) when missing, or exit with an actionable error if the build can't run. - run-web.ts: invoke ensureWebBuild before startHonoServer in the prod path (--dev runs Vite directly and skips it). - scripts/smoke-web.mjs + smoke:web: start --web against built dist and assert GET / returns 200 with the injected __INSPECTOR_API_TOKEN__. Wired into validate:launcher and a new CI step. - Docs: launcher README + AGENTS.md. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(web): surface spawn error in build-on-demand; clarify smoke comment Address PR #1497 review: - runViteBuild now logs result.error.message (e.g. ENOENT when npm isn't on PATH) before returning a null status, so the spawn-failure cause surfaces instead of only the generic actionable error. The build seam gains a `log` param; added a test covering the ENOENT path. - Reword scripts/smoke-web.mjs header so it no longer implies the readiness wait covers a cold build-on-demand vite build (it's sized for a pre-built dist, which validate/CI guarantee).

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	dc31c28102	fix(core): make "error" the canonical terminal status on a mid-session crash (#1490) (#1493) ... * fix(core): make "error" the canonical terminal status on a mid-session crash (#1490) On a real mid-session transport crash many SDK transports fire BOTH `onclose` and `onerror` in a transport-dependent order. The `onclose` guard (`if status !== "disconnected"`) let a trailing `onclose` downgrade a crash's `"error"` status back to `"disconnected"`, so the persistent terminal status differed by ordering: - onerror-then-onclose → "disconnected" - onclose-then-onerror → "error" `onclose` now treats `"error"` as terminal (only `"connected"`/ `"connecting"` → `"disconnected"`), so `"error"` is the canonical resting status in both orderings. It still emits the `disconnect` event exactly once so session-teardown consumers fire identically either way. Because the state managers gated list/message/subscription/task teardown on `getStatus() === "disconnected"`, holding the status at `"error"` would have left them stale in the onerror-first ordering — swapping one ordering-dependence for another. Introduce `isTerminalStatus()` (disconnected || error) and key every teardown guard off it so they clear identically regardless of crash ordering. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(core): single disconnect event when explicitly disconnecting from "error" (#1490 re-review) Addresses the non-blocking observation from the PR review: explicitly calling disconnect() from a held-"error" status could fire the `disconnect` event twice. close() can trigger the transport's onclose synchronously; onclose (holding status at "error") fired `disconnect`, then disconnect()'s own guard saw status still != "disconnected" and fired it again — a timing-dependence on whether the SDK closes sync. Add a `disconnecting` ownership flag: onclose defers its status set + `disconnect` event to disconnect() while it is set, so the explicit-disconnect path emits exactly one `disconnect` regardless of sync/async close. Crash-path onclose (flag unset) is unchanged. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * test(core): deterministically pin the sync-close disconnect double-fire (#1490 re-review) The real-stdio test asserts the single-disconnect invariant but may not exercise the sync-close branch (the one that double-fired) if the SDK stdio transport closes asynchronously. Add a test that overrides the SDK client's close() to invoke the transport's onclose synchronously, forcing the exact timing the `disconnecting` flag guards. Verified it asserts 2 (fails) without the flag and 1 (passes) with it.

Cliff Hall	b4716a1405	feat(core): surface mid-session transport failures via lastError (#1489) ... Closes #1323. Adds an `error`-event-driven `lastError` on useInspectorClient and a mid-session failure toast in App.tsx; the transport onerror is scoped to non-handshake (status !== connecting) so handshake failures stay on the connect() rejection path.
