Expose live resource subscriptions via a hook (#1325) (#1326)
* Expose live resource subscriptions via a hook (#1325)

Add ResourceSubscriptionsState that mirrors InspectorClient's subscribed
URIs as InspectorResourceSubscription[], resolving each URI against the
managed resources list (so the subscription tile shows server-supplied
name/title) and stamping lastUpdated on notifications/resources/updated.
Pair it with useResourceSubscriptions and wire App.tsx so the Resources
screen reflects subscribe/unsubscribe actions in real time.

* Address review notes on resourceSubscriptionsState

- Soften the onResourceUpdated comment: the client's dispatch is already
  guarded by subscribedResources.has(uri), so the re-check is true
  defense-in-depth rather than guarding a known hazard.
- Use this.getSubscriptions() in the statusChange handler so every emit
  goes through the defensive-copy path.
- Document the deliberate fallback to a synthetic Resource when a
  previously-listed resource is removed from the managed list while
  the user is still subscribed.

* Reflect subscribed state in preview + compact subscribed tile labels

- Wire `isSubscribed` on the ReadResourceState passed to ResourcesScreen
  by deriving it from the live subscriptions list in App.tsx. The
  ResourcePreviewPanel's SubscribeButton already flips its label to
  "Unsubscribe" when subscribed; without this derivation isSubscribed
  was always false and the button looked stuck on "Subscribe".
- In ResourceSubscribedItem, display only the last URI path segment
  (truncated with ellipsis if it still overflows) and surface the full
  URI via a hover tooltip. Keeps the Subscriptions pleat readable when
  resources have long path-style URIs.

* Auto-read resource on sidebar click

Clicking a resource in the URIs accordion now triggers onReadResource
in addition to setting the selection, so the preview panel jumps
straight to the pending → ok render path. Removes the unreachable
"Click to read this resource" placeholder, since the loader / preview /
error states always cover the rendered output for a selected resource.

* Render markdown resources via react-markdown + fix preview overflow

- Add react-markdown / remark-gfm dependencies.
- ContentViewer accepts an optional mimeType prop; when it matches
  text/markdown (or text/x-markdown), text blocks render via
  react-markdown wrapped in a `.markdown-content` container. Non-markdown
  text now uses the existing Code "wrapping" variant so long lines stay
  inside the panel.
- ResourcePreviewPanel infers `text/markdown` from a `.md` / `.markdown`
  URI suffix when the server didn't supply a mimeType, and threads the
  effective mime through to ContentViewer per content item.
- ResourcesScreen flex children get miw=0 so a long unwrappable line in
  the resource body can no longer push the preview past the viewport's
  right edge.
- App.css gains a `.markdown-content` ruleset constraining nested pre,
  table, code, and img elements to the container's width.

* Contain resource preview: sticky header/footer, scrollable body

Restructure ResourcePreviewPanel into a fixed-height column with the
resource title + URI pinned to the top and the timestamp / annotations /
subscribe-refresh actions pinned to the bottom. The content viewer area
in the middle now owns its own ScrollArea, so a long markdown body
scrolls within the panel instead of pushing the subscribe button below
the viewport.

In ResourcesScreen, the selectedResource branch (and the template
branch's right pane) now hosts the panel inside a PreviewPane Flex
column with the screen's max-height, and renderReadState wraps in a
FillDetailCard sized to fill that column. The legacy outer
ScrollArea.Autosize is removed for these panes since scrolling is
internal now.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* Auto-hide template after read; size preview to content with cap

- After the user clicks Read Resource on the template form,
  handleReadResource now clears selectedTemplateUri so the screen
  swaps from the template form to the resource preview. Previously
  both panels stayed mounted side-by-side.
- The preview no longer hard-fills the viewport. The Card uses a new
  "preview" theme variant (overflow: hidden) and is content-sized,
  capped at SCROLL_MAX_HEIGHT. ResourcePreviewPanel's flex column
  marks the header / meta / footer rows as `flex: 0 0 auto` and the
  ContentScroll as `flex: 0 1 auto` with `mih: 0`, so:
    - short content → card hugs it, footer sits right under the body
    - long content → card caps at viewport, ContentScroll shrinks
      and scrolls internally, footer stays pinned at the cap
- ScrollArea / Group imports in ResourcesScreen pruned to match the
  simpler single-pane layout.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* Cap template form panel at 40% width

A bare text input + Read Resource button stretched across the whole
main content area looks awkward on wide displays. Apply maw=40% to
the PreviewPane in the template branch so the form keeps a reasonable
form-field width regardless of viewport.

The preview branch is unaffected — resource bodies still get the full
main area for content.

* Live completion/complete suggestions on resource template inputs

Wires the server's `completions` capability through to the resource
template form so each variable's input becomes an Autocomplete that
fires `completion/complete` (debounced, 300ms) on every keystroke and
surfaces the returned values as a dropdown — mirroring v1's behavior.

- core/mcp/inspectorClientProtocol.ts: surface getCompletions on the
  protocol so non-runtime callers (state managers, hooks, tests) can
  depend on it. FakeInspectorClient gains a vi.fn-backed stub.
- ResourceTemplatePanel: accepts onCompleteArgument + completionsSupported.
  When both are present it renders Mantine Autocomplete instead of
  TextInput, debounces keystrokes via per-arg timers, aborts in-flight
  requests on the next keystroke, and disables client-side filtering
  (the server already filtered for the typed prefix).
- ResourcesScreen / InspectorView: thread the props through; the
  screen-level callback re-injects the active template's URI as the
  `ref: "ref/resource"` so the panel-level callback stays ref-free.
- App.tsx: wires onCompleteArgument to inspectorClient.getCompletions
  and derives completionsSupported from `capabilities?.completions`.

test(core): backfill coverage on inspectorClient + remote server (#1317)
* test(core): backfill coverage on inspectorClient + remote server

Resolves #1310. Drops the two TODO(#1310) exclusions from
clients/web/vite.config.ts (coverage.exclude); both files now pass the
per-file gate (lines >=90, statements >=85, functions >=80, branches >=50).

core/mcp/remote/node/server.ts (88.15 / 78.37 -> 97.29 / 100):
- Extract createTokenAuthProvider to its own file
  (core/mcp/remote/node/tokenAuthProvider.ts) so the 7 no-op
  OAuthClientProvider stubs can be unit-tested directly.
- Add focused integration tests covering the remaining gaps:
  * createTransportNode failure path on POST /api/mcp/connect
  * /api/mcp/send when transport is dead
  * /api/log non-JSON body (catch fallback)
  * forwardLogEvent unknown-level / no-messages / string-first-message
    fallbacks (lines 232, 240-242, 257-265 in the original)
  * /api/fetch missing-url + upstream-throw paths
  * /api/storage POST invalid storeId + invalid JSON body
  * /api/storage GET when the on-disk store is unparseable

core/mcp/inspectorClient.ts (73.48 / 72.09 -> 91.16 / 89.92):
Added a single "Coverage backfill (#1310)" describe block to the existing
integration test, plus a few unit-style cases:
- OAuth getters / setOAuthConfig / authenticate when oauthManager is unset.
- Simple session, roots, subscription, and instructions accessors.
- subscribe / unsubscribe error paths against a server without the
  subscribe capability; happy path against one with it.
- getPrompt + readResourceFromTemplate happy path + expansion-failure.
- setLoggingLevel "Server does not support logging" guard.
- getAppRendererClient (null before connect, cached proxy after).
- OAuth + stdio: authenticate() throws via getServerUrl()'s stdio check.
- listChanged notifications: tools/resources/prompts handlers via the
  fixture add_tool / add_resource / add_prompt tools.
- Misc tiny branches: re-connect no-op, elicit form mode, getTaskCapabilities
  on a tasks-less server, receiver-task TTL cleanup + cancel via the
  private surface (the focused-unit pass the issue describes).
- defensive `if (!this.client) throw` guards: one nullify-and-call test
  exercises 16 of them via a single instance, plus the connect() entry
  guard.

The receiver-task internals test uses (instance as unknown as
{ private fields... }) to drive createReceiverTask / cancelReceiverTask
/ TTL cleanup directly; per the issue, refactoring private helpers to
be testable from a unit test was authorized.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* test(core): address #1317 PR review feedback

- Rename the misnamed "listChanged notifications" describe in
  inspectorClient.test.ts to "capability detection after connect", since
  the test asserts only on getCapabilities() round-tripping and never
  triggers or observes a notification dispatch. Real dispatch coverage
  lives in the adjacent "list_changed + resourceUpdated notifications"
  block. Kept the resources/prompts fixtures with a note explaining why
  they are required for the server to advertise the matching capabilities.
- Expand the comment on the 250ms wait in remote-transport.test.ts'
  /api/mcp/send dead-transport test so it is clear the >= 500 assertion
  is intentionally permissive across both the dead-transport short-
  circuit and the downstream send-failure branches.
- Add a "keep this in sync" pointer on the nullify() helper so a future
  cleanup that removes any of the defensive `if (!this.client) throw`
  guards in inspectorClient.ts is reminded to drop the matching call here
  rather than silently under-covering.

refactor(core): apply v1.5-port cleanups deferred from #1306 (#1316)
* refactor(core): apply v1.5-port cleanups deferred from #1306

Addresses issue #1309 — five small, mechanical cleanups deferred from the
v1.5 runtime port:

1. Collapse BrowserOAuthStorage / NodeOAuthStorage / RemoteOAuthStorage
   onto a shared OAuthStorageBase. Three ~130-line duplicates become
   thin adapter wrappers; behavior + public API unchanged.
2. Re-enable erasableSyntaxOnly in tsconfig.app.json by rewriting the
   seven (plus two the issue missed in sampling/elicitation create-
   message) parameter-property constructors as explicit field + assign.
3. Route the lone console.error in inspectorClient.ts through this.logger.
4. Replace `${Date.now()}-${Math.random()}` with crypto.randomUUID() at
   the five local-only ID sites (message tracking + sampling/elicit).
5. Pin the remote-server hono app generic at new Hono<Env>() and drop
   the streamSSE cast. Root cause of the cast was an unresolved hono
   subpath: the tsconfig "hono/*" wildcard didn't honor the exports
   map, so hono/streaming leaked to the root-hoisted hono@4.12.12 while
   hono itself resolved to clients/web/hono@4.12.18. Replaced the
   wildcard with an explicit hono/streaming entry in both tsconfig.app
   and tsconfig.test, removing the package-identity mismatch.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* refactor(core): address #1316 PR review feedback

- Drop the stranded no-op getServerState() read at the top of
  clearClientInformation in OAuthStorageBase (carried over verbatim
  from the three originals).
- Drop the crypto.randomUUID() guard at the task-ID site so all
  six in-scope sites are consistent; the fallback branch was dead
  code on every supported runtime.
- Remove the residual `c as Context` cast at the streamSSE call site
  in core/mcp/remote/node/server.ts — once both hono imports
  resolve to the same package the route-typed Context flows through
  to streamSSE with no cast at all.
- Move the new `options` / `config` field declarations in
  RemoteClientTransport up with the rest of the field block, matching
  the layout used by the other five rewritten classes in this PR.

feat(core): port v1.5 InspectorClient + transports + auth subsystem (#1302) (#1306)
* wip(core): bulk-copy v1.5 InspectorClient runtime files (#1302)

Verbatim ports from origin/v1.5/main into v2/main core/:

- logging/ (2 files)
- storage/ + storage/adapters/ (4 files)
- auth/ + auth/browser/ + auth/node/ + auth/remote/ (16 files)
- mcp/config.ts + mcp/node/ (4 files, stdio transport)
- mcp/remote/ + mcp/remote/node/ (12 files, HTTP/SSE transport)
- mcp/inspectorClient.ts (~2169 LOC), messageTrackingTransport,
  fetchTracking, oauthManager, index, state/index

Total: ~7,800 LOC of source files, copied unmodified via
`git show origin/v1.5/main:<path> > <dest>`.

Also:
- Add deps: pino, hono, @hono/node-server, atomically, zustand, @types/node
- tsconfig.app.json: extend paths to resolve new node-only deps from
  core/, add "node" to types, disable erasableSyntaxOnly (v1.5 code
  uses parameter properties — TODO to re-enable in follow-up)

Compiles down to 47 type errors, all in three categories:
- 24 TS2305: v2 dropped v1.5 type exports (InspectorClientOptions,
  CreateTransport, InspectorClientEnvironment, AppRendererClient,
  SamplingCreateMessage class, ElicitationCreateMessage class,
  jsonUtils helpers, OAuth events). Per user direction, will re-add
  these to v2's diverged files (types.ts, samplingCreateMessage.ts,
  etc.) so the ported code stays verbatim.
- 15 TS7006: implicit-any params in v1.5 code (v1.5 tsconfig was
  looser than v2's noImplicitAny). Need explicit annotations.
- 8 other TS errors: ../package.json import, Transport|null narrowing,
  hono Context generic mismatch, one unused parameter.

Tests not yet ported (19 files, ~11,170 LOC).

* wip(core): integrate ported v1.5 InspectorClient + port tests (#1302)

Source integration (typecheck + build now pass):
- Re-add v1.5 types/classes dropped during v2 evolution:
  - types.ts: CreateTransport*, AppRendererClient, InspectorClient{Environment,Options}
  - samplingCreateMessage.ts / elicitationCreateMessage.ts: classes + keep v2's
    InspectorPending{Sampling,Elicitation} interface
  - inspectorClientEventTarget.ts: oauth* event keys
  - json/jsonUtils.ts: convertParameterValue / convertToolParameters /
    convertPromptArguments + ParameterSchema
- inspectorClient.ts: replace `../package.json` import (v2 has no
  core/package.json) with a hardcoded identity constant
- remote/node/server.ts: cast hono Context for streamSSE (hono's
  generic typing tightened since v1.5)
- oauth-callback-server.ts: drop unused hostname field
- tsconfig: enable @types/node, add paths for new bare-module deps
  (pino, zustand, hono, atomically) in app + test configs
- vite.config.ts: mirror those module aliases for the unit project
  (which runs from repoRoot)

Tests ported (19 files, ~11K LOC) under clients/web/src/test/core/:
- All core/__tests__/auth/* (7 files)
- inspectorClient.test.ts + 4 OAuth variants
- mcp/oauthManager.test.ts, jsonUtils.test.ts
- transport, remote-transport, remote-server-config, storage-adapters
- helpers/oauth-client-fixtures.ts
Bulk-rewrote `from "../mcp/…"` → `from "@inspector/core/mcp/…"` etc.

Current state:
- typecheck: 0 errors
- build: passes (vite v8, 788 modules)
- unit tests: 1014 / 1034 pass (937 pre-existing + 77 new core tests)
- 20 failures in 13 files; failure modes:
  - 13 file-load failures needing the v1.5 `test-servers/` package
    (@modelcontextprotocol/inspector-test-server) which isn't in v2 yet
    or real fs/network not available in happy-dom
  - 7 assertion failures in discovery.test.ts + state-machine.test.ts
    (SDK 1.29 vs 1.25 API drift — mocks don't match new shape)

Coverage gate not yet checked against new files.

* wip(core): port test-servers, more types, partial test integration (#1302)

- Port v1.5 test-servers/ package (12 files, ~5K LOC) under
  repo-root/test-servers/, wire @modelcontextprotocol/inspector-test-server
  alias in both vite.config.ts (regex form) and tsconfig.test.json.
- Add deps: express ^5, yaml ^2, @types/express ^5.
- Re-export InspectorClientOptions/Environment/Transport* from inspectorClient.ts
  so v1.5 tests that import them from that module path keep resolving.
- Switch InspectorClientEventMap to use SamplingCreateMessage /
  ElicitationCreateMessage classes (matches v1.5 event payload contracts)
  while keeping the InspectorPending{Sampling,Elicitation} interfaces in
  the *.ts modules for v2 consumers that still use them.
- Fix verbatim-module-syntax issue in test-servers and drop unused stdio
  config field.
- Adjust inspectorClient.test.ts task types to TaskWithOptionalCreatedAt
  (SDK 1.29 tightened Task shape vs v1.5's 1.25).
- Drop spurious maxMessages/maxFetchRequests/maxStderrLogEvents from
  remote-transport.test.ts (never on InspectorClientOptions).

State:
- typecheck: 0 errors
- build: passes
- unit tests: 1099 / 1270 pass
- 171 failures in 10 test files, almost all integration tests that need
  real HTTP/fs/network (happy-dom can't host them). Next: add a node-env
  vitest project to run these properly.

* feat(core): port v1.5 InspectorClient + transports + auth subsystem (#1302)

Bulk-port of the v1.5 core runtime (~7,800 LOC source + ~16K LOC tests +
~5K LOC test-servers/) into v2. Files copied verbatim from origin/v1.5/main
via `git show >`; only minimal adapters added on the v2 side.

Subsystems landed
-----------------
- core/logging/, core/storage/, core/auth/ (browser + node + remote)
- core/mcp/ runtime: inspectorClient.ts (2169 LOC), oauthManager,
  messageTrackingTransport, fetchTracking, config, index
- core/mcp/node/ (stdio transport)
- core/mcp/remote/ + remote/node/ (HTTP/SSE transport + Hono server)
- test-servers/ package (composable MCP test servers, fixtures, harness)

v2 adapter layer
----------------
- types.ts: append CreateTransport*, AppRendererClient,
  InspectorClient{Environment,Options} (v2 had pruned these — v1.5 needs them)
- samplingCreateMessage / elicitationCreateMessage: keep v1.5 classes AND
  v2's Inspector Pending* interfaces in the same files
- inspectorClientEventTarget: add oauth* event keys; switch pending
  sampling/elicitation payloads to the classes (matches v1.5 contracts)
- json/jsonUtils: append convertParameterValue/convertToolParameters/
  convertPromptArguments + ParameterSchema
- inspectorClient.ts: re-export Options/Environment/Transport* so tests
  that import these from `inspectorClient.js` keep resolving; replace
  `../package.json` import with a hardcoded identity (v2 has no core/package.json)
- remote/node/server.ts: cast hono Context for streamSSE (hono generic
  tightened since v1.5)
- oauth-callback-server: drop unused hostname field
- tsconfig.app.json / tsconfig.test.json: add @types/node + paths for
  pino/zustand/hono/@hono/node-server/atomically/express/yaml, disable
  erasableSyntaxOnly (parameter-property syntax from v1.5)
- vite.config.ts: regex-form module aliases (so the package's exports
  field handles subpaths like `hono/streaming`, `zustand/middleware`),
  alias for @modelcontextprotocol/inspector-test-server → test-servers/src

Tests
-----
- 19 v1.5 test files copied under clients/web/src/test/core/,
  imports rewired to @inspector/core/* and @modelcontextprotocol/inspector-test-server
- 1004 unit tests pass; 298 storybook tests pass; coverage gate passes

Known follow-ups (out-of-scope here, tracked in TODOs)
------------------------------------------------------
- 13 integration test files are excluded from the unit project (spawn real
  HTTP/stdio servers; run real OAuth flows; mock SDK auth → happy-dom CORS).
  Needs a node-env vitest project. Files listed under `test.projects[0].test.exclude`.
- Source files exercised only by those integration tests are excluded from
  the coverage gate pending the node-env project. Listed under
  `test.coverage.exclude` with comment.
- Manual smoke tests against real stdio / HTTP / OAuth server per the AC
  on #1302 still need verification locally.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* docs/fix: address #1306 review (AGENTS tree, #1307 links, @types/node, .substr)

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

feat(core): port v1.5 hook layer (#1243) (#1300)
* feat(core): port v1.5 hook layer (useInspectorClient + useManaged*/usePaged* + log hooks)

Wholesale port of v1.5's React hook layer and the EventTarget-based state machinery the hooks subscribe to (#1243). Hooks decouple from the concrete InspectorClient via a new `InspectorClientProtocol` interface so this layer can land before the runtime class is ported.

Added under `core/`:
- `core/react/` — useInspectorClient + 5 useManaged* + 5 usePaged* + 3 log hooks
- `core/mcp/state/` — 5 managed*State + 5 paged*State + messageLogState + stderrLogState + fetchRequestLogState
- `core/mcp/inspectorClientProtocol.ts`, `inspectorClientEventTarget.ts`, `typedEventTarget.ts`, `samplingCreateMessage.ts`, `sessionStorage.ts`
- v2-only wrapper types in `core/mcp/types.ts`: InspectorUrlElicitRequest, InspectorPendingRequest, InspectorRequestHistoryItem

Tests live under `clients/web/src/test/core/` (28 new test files, 264 new tests). Test fake: `core/mcp/__tests__/fakeInspectorClient.ts`.

Build wiring:
- `vite.config.ts`: dedupe react/react-dom so core/ files resolve them via clients/web/node_modules.
- `tsconfig.app.json` / `tsconfig.test.json`: paths map react/react-dom/vitest to clients/web/node_modules so `tsc -b` resolves bare imports from core/ source files (which sit above the package's node_modules). Exclude core/__tests__ from app config; include in test config.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* review: address PR #1300 review findings

Bugs:
- fetchRequestLogState: add .catch() on sessionStorage.loadSession so a corrupt
  or unreadable session doesn't surface as an unhandled rejection (matches the
  saveSession swallow pattern).
- messageLogState: sync pendingRequestEntries when clearMessages() evicts a
  pending request entry, so a later response with the same id falls through
  to the append branch instead of mutating an unreachable map entry. Add tests
  for both predicate and no-predicate paths.

Cleanups:
- Extract mergeTaskIntoList helper to core/mcp/state/mergeTaskIntoList.ts so
  managed/paged RequestorTasks state classes share one definition.
- Add a one-line JSDoc note on each PagedTools/Prompts/Resources/Templates
  state explaining why they deliberately do not subscribe to *ListChanged
  (cursor invalidation mid-pagination).
- Document on useInspectorClient that appRendererClient is read lazily on
  every render and is not subscribed (changes once at connect time).

Carry-overs from v1.5 deliberately left for the follow-up InspectorClient
runtime port:
- Refresh/status-change race in Managed*State.refresh() (status check is only
  at entry; a disconnect during await can re-clear before refresh resumes).
- nextCursor exposure asymmetry across usePaged* (only usePagedRequestorTasks
  surfaces it via state field; others return it from loadPage() only).

feat(apps): add isAppTool helper in core (#1260) (#1272)
* feat(apps): add isAppTool helper in core (#1260)

Adds @modelcontextprotocol/ext-apps as a dependency (root + clients/web)
and a thin core/mcp/apps.ts wrapper exposing:

- getAppResourceUri(tool): re-export of getToolUiResourceUri so all
  Inspector clients consume the same nested/flat _meta resolution.
- isAppTool(tool): boolean predicate built on top of getAppResourceUri.

Both surface the underlying ext-apps throw on a malformed _meta.ui.resourceUri
(string that does not start with "ui://") rather than swallowing it — server
bugs should be visible.

Tests cover nested format, deprecated flat format, nested-wins precedence,
missing _meta, and the invalid-URI throw.

Refs #1260

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* test(apps): address PR #1272 review feedback

- core/mcp/apps.ts: convert getAppResourceUri from a typed const re-export to
  a function declaration so its export style matches isAppTool. Behavior is
  unchanged.
- core/mcp/apps.ts: document the filter-iteration implication on isAppTool —
  callers using tools.filter(isAppTool) will halt on a server-malformed URI.
- apps.test.ts: add the symmetric isAppTool false-case for `_meta.ui` present
  without `resourceUri`.

6b3cecd736 Address PR #1236 review feedback
- Rename RequestMethod → MessageMethod. The type covers notifications and
  results, not just requests; the new name matches the JSDoc.
- Normalize imports to the @inspector/core/mcp/types.js path alias in
  HistoryListPanel, historyUtils, and HistoryScreen (HistoryControls was
  already using the alias).
- Document the cast invariant in extractMethod: SDK types message.method
  as string, but every MessageEntry in this app originates from SDK
  schemas, so the narrowing is safe.
- Type SAMPLE_METHODS as MessageMethod[] in HistoryControls stories so
  the literal-type narrowing isn't lost across the spread.

Skipped two reviewer suggestions: the Mantine Select inline cast (reviewer
self-resolved) and the stale-methodFilter-on-clear UX edge case (deferred
as a separate follow-up — not a Phase 5 audit gap).

dde43ae47c Phase 5 audit: annotate spec, close HistoryControls partial
Audited every component under clients/web/src/components/ against its
v2_ux_interfaces.md entry. Added an "Audit results" section near the top
of the spec with the verified count (57/62 satisfied, 5 partial) and the
specific gaps still open.

While auditing, closed the HistoryControls gap directly:

- Added RequestMethod union type to core/mcp/types.ts, derived from the
  SDK's Client/Server Request and Notification schemas plus a synthetic
  "response" entry for result/error MessageEntries.
- Typed methodFilter and onMethodFilterChange in HistoryControls,
  HistoryListPanel, historyUtils.extractMethod with RequestMethod.
- Lifted the hardcoded METHOD_OPTIONS list out of HistoryControls into
  a required availableMethods prop. HistoryScreen now derives it from
  the live entries via useMemo + extractMethod.
- Updated HistoryControls.stories.tsx to pass availableMethods.

The remaining 5 partials (ElicitationUrlPanel, InlineElicitationRequest,
InlineSamplingRequest, ExperimentalFeaturesPanel, ResourceListItem) are
either blocked on the v2 core hook layer effort or call out follow-up
work that has its own design questions.

5a60da2a12 Drop multi-line JSDoc on ServerEntry
Per AGENTS.md, comment blocks should be one short line. The interface
name and per-field invariant comments already document the shape; the
extra block was redundant.

c5d02456e0 Phase 5: Lift ServerEntry into core/mcp/types.ts
ServerEntry was previously defined as `Pick<ServerCardProps, ...>` in
ServerListScreen, inverting the natural dependency direction (data shape
derived from a UI prop type). Phase 5's cleanup pass calls this out
specifically.

Move the canonical ServerEntry into core/mcp/types.ts and have
ServerCardProps extend it. ServerListScreen, InspectorView, and their
stories now import ServerEntry from core directly.

1149288ea6 Refactor ServerCard stack to use id-based callbacks
Distinguishes server `id` (the unique map key in MCPConfig.mcpServers)
from `name` (display label) so containers can dispatch by id without
relying on display strings. ServerCard, ConnectionToggle, ServerListScreen,
and supporting stories all updated.

- ServerCard: add `id` prop; all action callbacks now `(id: string) => void`
- ConnectionToggle: collapse `onConnect`/`onDisconnect` into single `onToggle`
- ServerListScreen: lift `activeServer` to a prop; combine `onSetActive` +
  `onToggleConnection` into a single `onToggleConnection(id)` callback
- Stories: use UUIDs for server ids so callbacks visibly carry ids, not names

Removes the "Direct"/"Via Proxy" connection mode concept, which is no
longer planned. ServerSettingsForm drops the section, ServerCard drops
the badge, InspectorServerSettings drops the field.

Removes the "Test Client Features" dropdown from ServerCard along with
its four handlers; that surface will live elsewhere.

TransportBadge now collapses `sse` and `streamable-http` into a single
"HTTP" label; ServerCard adds a grey transport descriptor next to the
badge ("Standard I/O", "SSE (Server Sent Events) [deprecated]",
"Streamable HTTP"). The version badge moves from the header row to sit
beside the transport badge.

ServerCard header no longer wraps; long server names truncate with
ellipsis.

Specification docs (`v2_scope.md`, `v2_screenshots.md`,
`v2_ux_interfaces.md`, `v2_ux_storybook.md`) updated to match.

771a67ee20 Phase 2: Refactor Server/Settings/ViewShell cluster to MCP SDK types
ServerCard: Replace flat scalar props (name, version, transport, status,
error) with grouped objects (config: MCPServerConfig, info?: Implementation,
connection: ConnectionState). Remove auto-connect useEffect — dumb
components must not self-dispatch side effects. Derive transport and
command/url from config.

ServerInfoContent: Replace flat props with initializeResult: InitializeResult
and clientCapabilities: ClientCapabilities from MCP SDK. Derive capability
lists by iterating the ServerCapabilities record.

ServerSettingsForm: Collapse flat setting props (connectionMode, headers,
metadata, timeouts, oauth*) into settings: InspectorServerSettings. Add
InspectorServerSettings type to core/mcp/types.ts.

ImportServerJsonPanel: Replace scattered scalar props (jsonContent,
selectedPackageIndex, serverName) with draft: InspectorServerJsonDraft.

ViewHeader: Replace serverName: string with serverInfo: Implementation.
Use ConnectionStatus from core types.

ConnectedView: Update to pass serverInfo: Implementation instead of
serverName. Use ConnectionStatus type.

Update all stories for ServerCard, ServerInfoContent, ServerSettingsForm,
ImportServerJsonPanel, ViewHeader, ServerListScreen, ConnectedView, and
UnconnectedView.

Add ajv as an explicit dependency in clients/web/package.json (was only
available transitively via @modelcontextprotocol/sdk). Add inline comment
on StdioServerConfig.type explaining the implicit-default contract and

8edff4ea77 Phase 0 foundations for component interfaces refactor
Stands up the type-only prerequisites for the v2 UX component
interfaces refactor per specification/v2_ux_interfaces_plan.md.

Phase 0.1 — MCP SDK dependency:
- Add @modelcontextprotocol/sdk ^1.29.0 and zod ^4.3.6 to both the
  root package.json and clients/web/package.json so component files
  can import Tool / Prompt / Resource / Task / LoggingLevel / etc.
  directly from the SDK.

Phase 0.2 — Inspector wrapper-types module:
- Create core/mcp/types.ts mirroring the type-only subset of v1.5's
  core/mcp/types.ts: MCPServerConfig (discriminated union), ServerType,
  MCPConfig, ConnectionStatus, StderrLogEntry, MessageEntry (Date
  timestamps, not ISO strings), FetchRequestEntry(+Base), ServerState,
  and the *Invocation types. Adds v2-only wrappers
  InspectorResourceSubscription and InspectorServerJsonDraft.
- Add core/mcp/taskNotificationSchemas.ts for the Inspector-owned
  notifications/tasks/list_changed signal (not in the SDK).
- Add core/mcp/elicitationCreateMessage.ts re-exporting ElicitRequest
  and ElicitResult plus an InspectorPendingElicitation interface for
  typing the pending-queue.
- Add core/json/jsonUtils.ts for the shared JsonValue / JsonObject
  types used inside core/mcp/types.ts.
- Copy v1.5's clients/web/src/utils/jsonUtils.ts (JsonSchemaType) and
  schemaUtils.ts (AJV-backed validators) verbatim so SchemaForm can
  switch off its local JsonSchema type.
- Copy v1.5's clients/web/src/lib/types/customHeaders.ts verbatim for
  ServerSettingsForm and the experimental panel.
- Add clients/web/src/types/navigation.ts with InspectorTab (UI-routing
  concept, lives with the web client rather than in core/).
- Wire tsconfig.app.json + vite.config.ts with the @inspector/core/*
  path alias so component files can import from core/ without
  relative-path hell.

Phase 0.3 — Vet (likely) hedges in v2_ux_interfaces.md:
- Follow-up sweep on commit 2ef257da. Replaces the remaining
  useMcpClient references with useInspectorClient, ties pending
  elicitation / sampling callbacks to the in-InspectorClient queue
  rather than a non-existent useElicitation / useSampling hook,
  corrects Task references to the SDK type (not an InspectorTask
  wrapper), corrects log hook wiring to useMessageLog, and strikes
  all remaining v2-only hooks with explicit "no v1.5 analog"
  annotations. grep "likely" specification/v2_ux_interfaces.md now
  returns zero results.

Phase 0.4 — Local-redeclaration inventory:
- specification/v2_ux_interfaces_phase_0_4_inventory.md enumerates
  every ad hoc local type (JsonSchema, LogLevel, TaskStatus,
  PromptItem, ResourceItem, ToolListItemProps, RootEntry, KeyValuePair,
  inline ConnectionStatus / transport unions) that will be replaced
  in Phases 1–4, including the file it lives in, every site that
  re-imports it, and the SDK / wrapper type that replaces it. Intended
  for the Phase 0 PR description and as a running checklist during
  the refactor.

Build state: npm run build / lint / format:check all pass in
clients/web.
