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). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XNdjEPKLG637X8YmhDiEk5 * Extensions: address Phase 3 review (mime drift-guard, story, exact em-dashes) - extensions-mimetype.test.ts (integration/node): assert MCP_APP_MIME_TYPE equals ext-apps' real RESOURCE_MIME_TYPE (imported) and that the client advertises it — a genuine drift guard, replacing the tautological literal check in the unit test (which now just asserts the type). - ConnectionInfoContent Modern story: carry the tasks extension on initializeResult.capabilities too, so the Server Extensions row demonstrates it (the row now reads negotiated server capabilities, not discoverResult). - Tighten the em-dash assertions from ">= N" to exact counts (3/3/2) now that the two extension sections em-dash by default.

Import ext-apps' EXTENSION_ID from the /server subpath in the node integration test (fine there; the browser build is what avoids /server) and assert UI_EXTENSION_KEY === it. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XNdjEPKLG637X8YmhDiEk5 * Extensions: clone the registry advertisement so builds never alias it (review) Address the Phase 3 re-review's optional defensive nit: buildClientExtensions returned the same object reference as the ADVERTISABLE_EXTENSIONS entry for the ui advertisement, so an in-place mutation of a stamped value (e.g. extensions[ui].mimeTypes) could corrupt the registry for later connections. structuredClone the advertisement on stamp; add a test asserting a mutated build doesn't leak into the next one. Nothing mutates it today — purely defensive.

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. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XNdjEPKLG637X8YmhDiEk5 * Address @claude review: era docstrings, era validation, stdio session label, AGENTS.md rule - Fix stale docstrings/comments in inspectorClient.ts, useInspectorClient.ts, inspectorClientEventTarget.ts, and ConnectionInfoContent.tsx: getProtocolEra() returns "legacy" (not undefined) on a plain legacy connect; it is undefined only when not connected. - Validate protocolEra at the storedFieldsToInspectorSettings read boundary (new shared isProtocolEra guard) so a hand-edited mcp.json read directly by the CLI/TUI drops an unknown era instead of passing it to eraToVersionNegotiation. 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. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XNdjEPKLG637X8YmhDiEk5 * Address re-review: dedupe isProtocolEra guard in remote server Replace the local isProtocolEra in remote/node/server.ts with the shared guard now exported from serverList.ts (already imported here), so the era literal set lives in one place and can't drift.

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).
Closes #1624

feat(connection-info): wire Connection Info modal to the connection handshake (#1377)
* feat(server-info): wire Server Info modal to the connection handshake Closes #1364 - Add ServerInfoModal wrapping the existing ServerInfoContent, mirroring the ServerSettingsModal layout. - Gate the Server Info button on ServerCard to render only when the connection is "connected". - Expose `getClientCapabilities()` on InspectorClient (and protocol + FakeInspectorClient), and surface it through useInspectorClient so the modal can render the client side of the capability handshake without poking the SDK Client's private state. - App.tsx: open the modal from the gated Server Info button, derive the active server's transport and OAuth details (synchronously, from the guided-OAuth state snapshot + persisted settings), and reset the open flag on InspectorClient `disconnect` so the modal does not auto-reopen on a future reconnect. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(server-info): dedupe modal header and render instructions in ContentViewer - Drop the in-content "Server Information" Title from ServerInfoContent and rename the modal title to "Server Information" so the modal renders one heading instead of two stacked ones. - Swap the instructions Blockquote for ContentViewer (copyable, with the existing wrapping Code variant) so long instructions wrap and the user can copy the full payload. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * refactor(server-info): rename ServerInfo -> ConnectionInfo The popup covers server identity AND client capabilities AND OAuth state — it's a snapshot of the live connection, not just the server. Rename to match what it actually shows. Also add a "Server Implementation" heading above the top section (name/version/protocol/transport) to balance the existing capability headings. - ServerInfoContent -> ConnectionInfoContent (directory, file, exports) - ServerInfoModal -> ConnectionInfoModal (directory, file, exports) - ServerCard button label "Server Info" -> "Connection Info"; prop onServerInfo -> onConnectionInfo - Modal title -> "Connection Info" - App.tsx / ServerListScreen / InspectorView wiring updated to match Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(connection-info): cap instructions block height so it scrolls in place A long server prompt (e.g. an Everything-style instruction document) was pushing the OAuth section and the modal chrome off-screen — users had to scroll the whole modal to reach the close button. Wrap the ContentViewer in ScrollArea.Autosize with mah=280 so the instructions section scrolls internally and the rest of the modal stays put. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat(connection-info): add subtle background to section headings Add a `section` variant for Title that paints the heading in the existing `--inspector-surface-subtle` token (same surface token already used for modal call-out panels). Apply it to each section heading in ConnectionInfoContent (Server Implementation, Server Capabilities, Client Capabilities, Server Instructions, OAuth Details) via a SectionHeading subcomponent constant, so the sections read as distinct cards against the modal background instead of bleeding into one stream of text. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(stories): wrap long import line in ConnectionInfoModal.stories.tsx Prettier flagged the import in CI. The line exceeded printWidth=80 and needed to wrap onto multiple lines. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(agents): require `npm run format` before committing Add a pre-commit instruction to run the auto-fixing `npm run format` ahead of `npm run validate`. `validate` runs `format:check` (non-fixing) which will fail CI on any unformatted file — running the auto-fixer first eliminates that class of failure entirely. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * chore(favicon): use theme/assets/MCP.svg as the favicon source of truth Point index.html's icon link at /src/theme/assets/MCP.svg so the same MCP logo asset already imported by ViewHeader is also the favicon. Delete the now-unused clients/web/public/favicon.svg. Vite resolves the source path during build and emits a hashed copy under dist/assets/. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(server-card): surface failed-handshake errors with a 5s auto-dismiss Two related fixes so the user actually sees what went wrong when a connect attempt fails (e.g. OAuth-backed server, bad URL, missing dev auth token): - App.tsx: add `connectInFlightRef` and skip clearing `activeServerId` in the InspectorClient `disconnect` listener while a connect attempt is in flight. The transport closes during a failing handshake and dispatches `disconnect` before the catch block sets `errorMessage`; without this guard InspectorView would map the card to plain "disconnected" and the InlineError would never render. - InlineError: opt-in `autoDismissMs` prop that runs a Mantine `slide-up` Transition exit animation after the message has been visible for the given duration. Visibility is derived from a "dismissed message" state (rather than a mounted boolean + setMounted-in-effect), so the timer re-arms whenever `error.message` changes without tripping the react-hooks/set-state-in-effect rule. ServerCard passes autoDismissMs={5000}. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * refactor(server-card): own InlineError visibility + animate parent-driven removal Move the 5s auto-dismiss timer and visibility state out of InlineError and into ServerCard so the slide-up exit animation runs in both cases: - Timer-driven: after 5s the alert animates out (existing behavior). - Parent-driven: when `connection.error` is cleared mid-flight (e.g. a successful reconnect), the alert ALSO slides up instead of vanishing. To keep the message painted during the parent-driven exit, ServerCard tracks a `lastError` state that mirrors `connection.error` only on its truthy edges. The conditional setState during render is the supported React pattern for "remember the last seen value of a prop"; gated on message inequality so it can't loop. The `useRef` version of this pattern failed `react-hooks/refs` (no ref writes/reads during render). InlineError is now a pure presentational component: `mounted` prop controls a Mantine `slide-up` Transition. The internal `autoDismissMs` prop is gone — its single caller has moved to the controlled `mounted` pattern. Closes the "error vanishes the moment the parent removes it" half of #1364 (the timer half landed in 6d147e0f). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * refactor(server-card): surface connection errors as a toast, drop InlineError Move handshake-failure messaging out of the ServerCard body and onto a Mantine toast (`notifications.show`). The inline alert had a 5-second visibility contract entangled with InspectorView's status pipeline, and the active card was flipping through error → disconnected → error during a failing handshake; surfacing the error as a toast sidesteps that whole timing problem and keeps the card focused on the live status indicator. - App.tsx: toast on the connect-catch path; drop `errorMessage` state + `connectInFlightRef` (the latter was only there to keep the inline alert visible past the transport's close event). - InspectorView: drop the `errorMessage` prop and the `connectionStatus === "error" && errorMessage` mapping branch. - ServerCard: drop the InlineError rendering + the displayedError / errorVisible visibility state machine. - Delete the InlineError component — no other consumers. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * chore(notifications): anchor toasts to the bottom right Move the Notifications portal from top-right to bottom-right so a connection-failure toast doesn't overlap the ViewHeader / tabs row. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * review: address PR feedback on the Connection Info modal 1. Hoist `EMPTY_CLIENT_CAPABILITIES = Object.freeze({})` to module scope in `useInspectorClient` so the fallback returns a stable reference (avoids invalidating downstream `useMemo`/`useEffect` deps when no client is attached). 4. Drop the `?? "stdio"` silent fallback on `connectionInfoTransport` in the JSX — gate the modal render on `activeServer` too. The "stdio" default still lives at the derivation site (config.type is schema-optional and `ServerType` is required by the modal prop), but the gate makes the invariant explicit. 6. Replace the raw `document.querySelector("button.mantine-CloseButton-root")` in `ConnectionInfoModal.test.tsx` with `screen.getByRole("button", { name: /close/i })`. Add `aria-label="Close"` to the CloseButton so the assertion (and screen readers) have a name to match on. 7. Switch the OAuth scope splitter from `/\s+/` to the literal `" "` per OAuth 2.1 §3.3. Also clarify in comments: 2. Note that `connectionInfoOAuth` uses snapshot-at-open semantics on purpose — token refreshes mid-session won't re-render the modal. 5. Note that we prefer the AS-advertised `authorization_endpoint` over `authorizationUrl` because the latter is per-flight noise (state, code_challenge) rather than a stable identifier. Finding 3 (modal exit animation short-circuited by the `{initializeResult && …}` guard) left as intentional — we want the snap-shut on disconnect so a stale info dialog can't keep rendering with no live client behind it. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(connection-info): tighten the OAuth memo comment per re-review The reviewer noted that "snapshot-at-open" was imprecise — the memo re-runs on any of its deps (connectionStatus, inspectorClient, activeServer), which includes settings edits that re-reference the active server. Reframe as "snapshot-at-last-derivation" and call out the natural triggers (server switch, reconnect, settings edit) so a future reader doesn't conclude the memo is open-only.
