a7c4c5260e fix: bound the 401/403 body read so an unending body is released (#2297)
Copilot review round 1. With the tracker below the auth-challenge
interceptor, its background clone kept draining a 401 body after the
interceptor cancelled its own branch — so a body that never ended left the
connection live. Read a 401/403 body up front instead, capped at 64 KiB and
2s, and cancel the clone's reader when either bound is hit so the
interceptor's cancel releases the source. The body now lands on the entry
itself before the challenge is thrown.

Also cover the web path end to end: a streamable-http 401 on
/api/mcp/send reaches the event stream with its status and body.

af4b574234 fix: record an intercepted 401's status, headers and body (#2297)
The network tracker wrapped the auth-challenge interceptor, so a 401/403
never reached it as a response: the interceptor cancelled the body and
threw, and the tracker logged only the thrown error. NetworkEntry renders
its response section only when a status is present, so the body — and the
WWW-Authenticate resource_metadata and scope — were never shown.

Move the tracker below the interceptor so it records the real response and
clones its body before the interceptor cancels it, and stop awaiting that
cancel: with the tracker's clone as the other tee branch, the cancel settles
only once the clone reads to the end, which would hang on an unending body.

c565b56fcd fix: address Copilot review round 2 on #2318
- fetchTracking: media types and HTTP methods compare case-insensitively;
  a `Request` input's own method is honoured; the SSE line scanner
  accepts LF, CRLF and a bare CR, holding a trailing CR until the next
  chunk decides whether it is half of a CRLF.
- MessageTrackingTransport does not report a send failure for a request
  the caller aborted through `requestSignal`, and InspectorClient keeps a
  request whose send failed with a request timeout — both are sent,
  unanswered requests, which is the state to keep reporting.
- createTransportNode builds a fetch tracker when any tracking callback
  is supplied, not only `onFetchRequest`.
- RemoteClientTransport's relay wait expires with the SDK's own timeout
  shape, so the web client's relay timeout is annotated like every other.

d57801d7b3 feat(core): report connection state on a request timeout (#2318)
A request timeout used to surface as a bare `Request timed out`. Every
fact needed to explain it was already in-process: what the client was
still waiting on, when it last heard back, and the state of the
standalone GET notification stream. The SDK's timeout now rejects with
all three, and the same snapshot is shown live in Connection Info and
on the Network entry for the stream.

- core/mcp/connectionDiagnostics.ts: the snapshot type, its one-line
  description, and `annotateRequestTimeout`, which rebuilds the SDK's
  per-request timeout with the state at that moment.
- InspectorClient decorates the SDK Client's `request` (the one funnel
  every verb goes through) so the annotation covers the whole surface;
  tracks outstanding requests with their send time, the last response,
  and the most recent long-lived transport stream; exposes
  `getConnectionDiagnostics()` and `connectionDiagnosticsChange`.
- fetchTracking watches a long-lived stream through a tee'd clone,
  counting SSE events and reporting the close, via a new
  `updateStream` callback wired through the node transport, the remote
  session (`fetch_stream_update`), and the browser transport.
- FetchRequestLogState patches `entry.stream`; the Network entry's
  placeholder reports the event count and open/closed state.
- Connection Info gains a Connection Activity section, ticking while
  open (`useTickingClock`).

48b393014a fix(auth): address review — observe SSE explicit fetch, isolate test state
- The SSE branch selects a caller-supplied `eventSourceInit.fetch` as-is, so
  it bypassed the challenge observer and a first-time legacy SSE
  authorization lost the advertised URL the same way. Observing is passive,
  so it is applied to that fetch too while the deliberate no-proxy-wrap rule
  stays. Covered behaviorally against a 401-serving server.

- Dropped an `as unknown as typeof fetch` from the new integration test
  (banned by AGENTS.md, and it erased the signature); the spy is typed as
  `typeof fetch` directly. The `as MCPServerConfig` beside it was
  unnecessary too.

- The integration test reused a per-pid OAuth storage file. SDK `auth()`
  persists the advertised URL in its discovery state, so a rerun could
  satisfy discovery from that cache and pass with the plumbing removed —
  which would have quietly falsified the regression check. Fresh mkdtemp
  per run, removed in teardown.

Adds observer unit tests (challenge reported, body untouched, 403 included,
silent on success).

597e1bd25f fix(auth): carry resource_metadata into first-time legacy authorization
The challenge-driven plumbing did not reach the default CLI/TUI flow. With
no stored token in the legacy era, InspectorClient deliberately builds the
transport with no authProvider (so the SDK cannot open a browser before the
callback server is listening), which also leaves challenge interception off;
the 401 then surfaces as the SDK's headerless UnauthorizedError and the
runner calls authenticate() with no challenge in hand. So a server serving
metadata only at the advertised path still failed there — including for the
legacy showcase the README instructs.

Add a passive counterpart to the challenge interceptor: an observer fetch
that reports every 401/403 without touching control flow or the body. The
OAuthManager records the advertised URL from it and uses it in
authenticate() and its CIMD pre-registration. Latest-wins, including
clearing when a later challenge advertises none.

Also: the fixture helper dropped an explicitly supplied empty
resourceMetadataPath by truthiness, bypassing validation and silently
reverting to the well-known route.

Covered by a direct-client integration test that drives connect ->
authenticate() against the real server and asserts the advertised path was
requested and the well-known one never was; verified failing without the
fix.

d90a955164 fix(proxy): route through undici's own fetch and keep undici external
Corporate-proxy users could not connect to any remote MCP server from v2.
Two independent defects, both reported in #2067.

1. The web and TUI bundles inlined undici. It was declared in the root and
   `clients/cli` manifests but named in no client's tsup `external` list, and
   tsup auto-externalizes only what the *nearest* manifest declares — so
   esbuild inlined 1.05MB of it into `clients/{web,tui}/build/`. undici is
   CommonJS, so the emitted chunk's `require("assert")` hit esbuild's ESM
   `__require` shim and threw `Dynamic require of "assert" is not supported`.
   The rejected `import()` surfaced as "the `undici` package is not available",
   telling users to install a package that was already present — and could not
   have helped, because the specifier had been rewritten to a relative chunk at
   build time.

2. `withProxyDispatcher` injected a *userland* undici `EnvHttpProxyAgent` into
   Node's *built-in* fetch. That couples two different copies of undici at the
   dispatcher handler interface, which is not stable across majors: Node 22
   embeds undici 6, Node 24 embeds 7, Node 26 embeds 8. A userland undici 8
   agent handed a built-in undici 7 handler is rejected with
   `fetch failed: invalid onRequestStart method`, and the request never leaves
   the process. So fixing the bundling alone would only have converted the
   web/TUI failure into the CLI's.

Both halves of the pair now come from userland undici — its `fetch` and its
`EnvHttpProxyAgent` — which keeps the handler inside one copy and works
unchanged from the Node 22.19 engine floor through Node 26. Deleting the
wrapper in favor of Node's native `NODE_USE_ENV_PROXY` was not an option:
measured, it is unsupported on 22.19 (the floor) and only lands mid-22.x.

Because undici's `Response` is a different class from `globalThis.Response`,
the proxied fetch re-wraps each response as a genuine global `Response`,
streaming preserved. Without that, `res instanceof Response` is false for
callers that test it — including the SDK's OAuth error formatter, which would
degrade every message to `Raw body: [object Response]`.

The proxy now sits at the bottom of the fetch stack (`environment.fetch` for
the Node clients, and the `createTransportNode` default for the web backend,
its one caller that supplies no `fetchFn`) rather than wrapping the transport's
fetch. Proxying means *substituting* the fetch, not decorating one, so wrapping
a supplied `fetchFn` would discard it; installing it underneath lets
InspectorClient's own wrappers compose over it. A side effect worth having:
OAuth discovery and token requests go through `environment.fetch` too, and were
never proxied before.

Guarding it:

- `undici` is added to all three tsup `external` lists and removed from
  `clients/cli/package.json`, so it is root-declared only, per the placement
  rule in AGENTS.md. The two installs had already drifted (root 8.5.0 vs cli
  8.9.0).
- New `npm run verify:bundle-externals` fails if any package a client declares
  external was inlined into that client's bundle anyway. It reads the *built
  output*, not the config — those two disagreed for four releases — and derives
  what to check from each client's own `external` array, so a newly
  externalized package is covered without editing the guard. Verified against
  the real pre-fix artifact, which it flags.
- The proxy tests now drive a real forwarding proxy rather than a mock. That
  matters: defect 2 was a runtime interface mismatch, which no mock can catch
  because no mock ever dispatches.

AGENTS.md's must-not-bundle rule (added by #2082) is extended with why undici
slipped past it, and notes the `node -e` trap — probing the bundled chunk with
`node -e` falsely succeeds, because it exposes a global `require` that
satisfies esbuild's guard.

Closes #2067

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

* 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.

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).

Closes #1624

  intercept), not the bare proxy-aware baseFetch.
- clients/cli/README.md: fix the §5 mid-session validation link to use the
  ../../specification/ prefix like the sibling links in the same sentence
  (previously resolved to a nonexistent clients/cli/ path).

Both flagged by the @claude review of PR #1601; comment/doc-only, no runtime change.

b152f74ccd fix(ci): run CI on Node 22.x and correct undici 8 Node floor (#1563)
undici 8.5.0 requires Node >= 22.19.0 (its declared engines), so CI's
Node 20.x could not load undici's CacheStorage (missing
webidl.util.markAsUncloneable) and the proxy integration tests failed.
Bump the CI setup-node to 22.x to match the repo's Node floor.

Reconcile the declared floor with undici's real requirement: bump root
engines.node to >=22.19.0 and correct the CLI README note (undici 8.5.0
needs >=22.19.0, not >=22.7.5). Also document proxy support in the web
README and clarify that a caller-supplied eventSourceInit.fetch bypasses
the proxy wrapper by design.

when a standard proxy env var is set, so the CLI and web backend can reach
remote MCP servers through corporate proxies with zero new flags. undici is

at the repo root and in the CLI client; a missing undici raises an actionable
error. Documents the behavior and dependency in the CLI README.

feat(network): add Network screen surfacing backend fetch log (#1355) (#1363)
* feat(network): add Network screen surfacing backend fetch log (#1355)

Routes `FetchRequestLogState` to a new Network tab so users can inspect
HTTP-layer request/response headers, status, duration, and category
(auth vs transport) of every fetch the backend makes for an active
session. Adds `NetworkControls` + `NetworkStreamPanel` + `NetworkEntry`
groups, a `monoBreak` Text theme variant for long header values, and
wires onClearNetwork / onExportNetwork (JSON download) from `App.tsx`.

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

* fix(network): include request / response bodies in search filter

Headers were already covered but bodies were not, so searches for
strings that live inside the JSON-RPC payload (e.g. "jsonrpc",
"initialize", a tool name) silently returned no matches.

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

* fix(network): always render Response Body section, note streaming

Streaming responses (text/event-stream, application/x-ndjson, POST to
/mcp) are intentionally not body-captured by the fetch tracker, so the
section was silently omitted. Now whenever a response was received we
render the section, with either the body, a "(empty)" note, or a
"Streaming response — body not captured" note keyed off content-type.

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

* fix(network): capture response bodies via async body-update events

Two related fixes:

1. The fetch tracker was marking every streamable-HTTP POST /mcp call as
   "not captured" because the response content-type is text/event-stream.
   In practice those streams are bounded — the server sends the
   JSON-RPC reply (sometimes preceded by progress events) and closes —
   so we can clone the body and read it. Only GET + SSE / ndjson is the
   unbounded long-lived channel that has to stay uncaptured.

2. Reading the body inline blocked the transport from processing
   progress notifications until the entire stream finished, breaking the
   `resetTimeoutOnProgress` integration test. The body is now read in
   the background and dispatched via a new `fetchRequestBodyUpdate`
   event that the FetchRequestLogState patches into the matching entry
   by id. Plumbing wires through node/transport, the remote SSE channel
   (RemoteSession, RemoteClientTransport), and the remote event types.

Also hides the Network tab when the active server is stdio (no HTTP
traffic to surface) and bumps the inline body preview limit to 100 KB
so typical tools/list responses render rather than tripping the "too
large" notice.

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

* feat(network): show orange SSE badge for long-lived stream entries

Adds a small "SSE" badge to the right side of the NetworkEntry header
(left of the HTTP status badge) when the response is a long-lived
streaming channel (GET + text/event-stream or application/x-ndjson) —
the only case where the body genuinely isn't captured. Makes the
"not captured" placeholder less surprising at a glance.

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

* fix(network): address PR review findings

- Stop capturing OAuth response bodies (drop updateResponseBody from the
  effectiveAuthFetch tracker). Restores pre-PR behavior for auth-category
  entries so live access_token / refresh_token values can't leak into the
  Network tab body preview during a screen-share. Headers + status are
  still tracked.
- Extract `isLongLivedStreamResponse(method, contentType)` to
  core/mcp/fetchTracking so the rule lives in one place; consumed by the
  tracker and the NetworkEntry UI placeholder.
- Document the intent of NetworkEntry's `useEffect` (the list-level
  toggle is authoritative; per-entry overrides are intentionally
  discarded on each list toggle).
- Rename MAX_INLINE_BODY_BYTES → MAX_INLINE_BODY_CHARS (`.length` is
  UTF-16 code units, not bytes) and update the user-facing notice.
- Switch NetworkStreamPanel's search from joined-string `.includes` to
  per-field `.some(.includes)` so a term can't span field boundaries.
  Regression test added.
- Add aria-label to ListToggle ("Expand all" / "Collapse all") — both an
  a11y improvement and a stable selector that lets the panel test stop
  fishing the button out by text-content negation.

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

* test(network): use ListToggle aria-label in panel + modal tests

Cleanup spotted in PR review follow-up:

- HistoryListPanel + ServerSettingsModal previously fished the ListToggle
  out by empty text content because the toggle had no accessible name.
  Now that ListToggle exposes "Expand all" / "Collapse all", both tests
  can use getByRole + name and the stale comments go away.
- ListToggle's own tests now assert the aria-label contract so a future
  refactor can't silently drop it.

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

* fix(network): expose category toggle state via aria-pressed

The category UnstyledButtons in NetworkControls previously communicated
their toggled state only via background color. Adds aria-pressed={active}
so assistive tech can discover the on/off state without visuals, with a
test that asserts the attribute tracks the visibleCategories prop.

feat(servers): persist per-server settings to mcp.json (#1352) (#1353)
* feat(servers): persist per-server settings to mcp.json (#1352)

- Add optional `settings` node alongside the transport config in each
  `~/.mcp-inspector/mcp.json` entry. Round-trips through
  `mcpConfigToServerEntries` / `serverEntriesToMcpConfig` and the
  `/api/servers` POST/PUT routes.
- Drop `MCPServerConfig.headers` from `SseServerConfig` /
  `StreamableHttpServerConfig` and remove the headers textarea from
  `ServerConfigModal`. Custom headers are now entered only in
  `ServerSettingsForm` and reach the wire via `settings.headers`.
- Wire `ServerSettingsModal` into `App.tsx`; saves dispatch through a new
  `useServers.updateServerSettings` mutator. `updateServer` carries the
  existing settings across config-only saves so they aren't dropped.
- Apply settings on the *first* outbound request after a server loads —
  no need to open the settings form first:
  - `settings.headers` → SSE / streamable-http wire headers.
  - `settings.metadata` → `InspectorClientOptions.defaultMetadata`,
    merged into every outgoing `_meta` (call-time keys win).
  - `settings.requestTimeout` → `InspectorClientOptions.timeout`.
  - `settings.connectionTimeout` → Promise.race wrapper around connect().
  - `settings.oauth*` → pre-seeded OAuth client credentials.
- `RemoteConnectRequest` carries `settings` so the remote backend can
  source transport headers from the same source as the local path.
- `oauthClientSecret` is persisted in `mcp.json` alongside stdio `env`
  values, both protected by the file's `0o600` permission.
- Update `specification/v2_servers_file.md` with the new shape and the
  removal of the legacy headers field.

Tests: round-trip in `serverList.test.ts`; persistence on POST/PUT in
`servers-route.test.ts`; first-connect header injection in
`transport.test.ts`; `defaultMetadata` merging in
`inspectorClient.test.ts`; `useServers.updateServerSettings` +
`updateServer` settings-preservation in `useServers.test.tsx`.

* fix(servers): rebuild InspectorClient on every connect so settings refresh

The previous onToggleConnection branch reused the existing InspectorClient
on a same-server reconnect, which froze settings at the moment the client
was first constructed. Editing headers, metadata, timeouts, or OAuth
credentials in the settings form was therefore invisible until the user
either switched servers or reloaded the page — surprising right after a
visible save.

Always call setupClientForServer on (re)connect so the latest
target.settings flow through to the transport's headers / requestInit, to
defaultMetadata, and to the OAuth manager.

Also adds remoteClientTransport tests that pin the wire-level contract:
settings round-trip through the /api/mcp/connect body when supplied, and
the field is omitted when no settings are configured.

* fix(history): stop wiping pendingRequestEntries inside the connect event

State managers (ManagedToolsState, ManagedPromptsState, ManagedResourcesState,
ManagedResourceTemplatesState, ManagedRequestorTasksState) handle the
client's "connect" event by calling `void this.refresh()`. The synchronous
portion of refresh runs through SDK Protocol.request → transport.send →
MessageTrackingTransport.send → trackRequest, all before yielding to the
network — so each list request gets tracked into MessageLogState's
pendingRequestEntries inside the same connect event dispatch.

MessageLogState's own "connect" listener was registered after those state
managers (it's the last one constructed in App.tsx) and cleared
pendingRequestEntries on every connect. Listener order meant the clear ran
*after* the requests were tracked but before their responses arrived,
leaving the history with unmatched "response" entries marked PENDING.

The clear-on-disconnect (via statusChange → disconnected) already handles
session-boundary cleanup, so clear-on-connect was purely defensive and now
actively harmful. Drop the connect listener; keep the disconnect path.

Tests: updated the unit test to assert the new behavior (connect does not
clear); added an integration regression that wires a sibling connect
listener firing listTools and asserts the response folds into the request
entry instead of appearing as an orphan.

* chore: drop accidentally tracked debugging screenshot

pending-requests.png was a local debugging artifact attached to a
conversation, not source. Remove it from the tree (the working copy is
kept so the user still has it locally) and rely on the existing untracked
behavior going forward.

* test(servers): add e2e check that settings.headers reach upstream MCP

Stitches the full v2 pipeline together in one assertion:

  browser-style RemoteClientTransport
    → POST /api/mcp/connect (settings in body)
    → backend createTransportNode applies settings.headers to requestInit
    → SDK StreamableHTTPClientTransport
    → upstream MCP test server

Captures the upstream HTTP request via FetchRequestLogState and asserts
both `X-Tenant` and `X-Trace` are present on the outbound POST. Catches
any regression that breaks the wire between the form and the upstream
server in a single integration test, instead of the previous coverage
which exercised each hop in isolation.

* fix(ServerSettingsModal): invert ListToggle compact prop so icon matches state

ListToggle's `compact` prop represents the list's *current* compact state:
true means "currently compact" and renders the expand icon to advertise
the action (open up). The settings modal was passing
`compact={allExpanded}` — exactly inverted. When all sections were open
it showed the expand icon (suggesting "open more") and when collapsed it
showed the collapse icon, opposite of every other ListToggle caller in
the app.

* style(HistoryListPanel): match ServerListScreen Export button — rename + default variant

Renames "Export JSON" to "Export" and switches from the subtle ToolbarButton
to the same `Button variant="default"` used by ServerListControls so the
two Export affordances look identical across screens. Also moves the
button to the right of the ListToggle (mirroring the order on the server
list screen) and disables it when there are no entries to export.

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

* style(HistoryListPanel): move Clear button to top toolbar, match Export style

Moves the Clear affordance out of the "History (N)" section header and
up to the panel toolbar alongside Export, where it now uses the same
`Button variant="default"` styling. Order in the toolbar is now:
ListToggle · Clear · Export. Clear is disabled when there are no
unpinned entries to remove (pinned entries are intentionally preserved).

ToolbarButton helper is unused after this change and dropped.

* chore: ignore local debugging screenshots at repo root

Stops `git add -A` from re-staging the `*.png` files Claude Code drops
at the repo root from attached conversation screenshots. The pattern
only matches the top-level (`/*.png`) so legitimate image assets in
subdirectories (e.g. `clients/web/public/`) still get tracked when
explicitly added.

Also untracks the two screenshots that slipped through previously
(initialize-request.png, pending-requests.png).

* style(LogStreamPanel): match HistoryListPanel button styling

Clear / Export / Copy All on the Logging screen were rendered with the
subtle ToolbarButton helper while History's equivalents use
`Button variant="default"`. Switch all three to the default variant so
the toolbars look identical across screens and mirror the disabling
behavior — each button is now disabled when `entries.length === 0`.

ToolbarButton helper is unused after this change and dropped.

* fix(servers): address PR review — debounce save, preserve-on-omit PUT, validate shape, lift connect timeout

Round-up of fixes from https://github.com/modelcontextprotocol/inspector/pull/1353#issuecomment-4526861959:

1. ServerSettingsModal saves were firing on every keystroke (one PUT +
   full mcp.json refresh per character). App.tsx now debounces by 300ms
   and flushes on modal close so a burst of edits coalesces into one PUT
   and the form value can't flicker back mid-typing.

2. `PUT /api/servers/:id` with an omitted `settings` field used to
   silently wipe the persisted settings node. The route now treats the
   three intents distinctly:
     - field omitted  → preserve existing on-disk settings
     - explicit null  → clear the settings node
     - settings object → validate + apply
   `useServers.updateServer` is simplified to drop the client-side
   carry-through hack, and the test that documented the broken behavior
   is flipped + augmented with explicit-clear and bad-shape cases.

3. `connectionTimeout` Promise.race is moved from App.tsx into
   `InspectorClient.connect()`, reading `this.serverSettings?.connectionTimeout`.
   TUI/CLI consumers now get the same behavior; on timeout the client
   internally disconnects so the next connect starts clean.

4. Custom Headers hint in `ServerSettingsForm` notes that `Authorization`
   is owned by the OAuth flow when OAuth is configured — avoids the
   sharp edge where the SDK's authProvider silently overwrites a
   user-set Authorization header.

5. New `validateSettings` on the server route rejects malformed shapes
   (`settings: []`, `settings.headers: "oops"`, non-numeric timeouts,
   etc.) with 400 instead of letting them persist and crash the UI.

7 (nit). Renamed `settings` → `savedSettings` inside `setupClientForServer`
   so the variable holding the persisted settings doesn't shadow the
   later locally-derived values.

Follow-ups opened separately:
  #1356 — Move oauthClientSecret out of mcp.json into the OS keychain (review #6).

* fix(servers): address PR review pass 2 — connect-timeout test, unmount cleanup, tagged intent, lenient settings read

Pass-2 review at https://github.com/modelcontextprotocol/inspector/pull/1353#issuecomment-4527089705:

(a) New integration test pins the new client-layer connect-timeout
    contract: a hanging stub transport with `connectionTimeout: 50`
    rejects with the descriptive error and lands the client in "error"
    status. Documents what TUI/CLI consumers should expect from the
    lifted Promise.race in InspectorClient.connect().

(b) useEffect cleanup clears `pendingSettingsTimerRef` on unmount so a
    route change or HMR mid-debounce can't fire one stale PUT against
    an unmounted component.

(c) Refactor the PUT-route `settingsIntent` discriminator from
    `"preserve" | "clear" | { value }` to a tagged union with `kind`,
    and consume it with a `switch` for exhaustiveness — reads cleaner
    and makes adding a fourth intent painless.

(d) `normalizeMcpServers` now runs `validateSettings` on the on-disk
    settings node and silently strips it if invalid, mirroring the
    existing lenient-on-read pattern from `normalizeServerType`. Closes
    the read/write asymmetry where a hand-edited malformed `settings`
    could survive on disk and get carried through preserve-on-PUT.
    New route test pins the strip-on-GET + no-propagate-on-preserve-PUT
    behavior.

* fix(servers): pass-3 review — patch-style PUT, toast on close-flush fail

Pass-3 review at https://github.com/modelcontextprotocol/inspector/pull/1353#issuecomment-4529276897.

(b) `PUT /api/servers/:id` now treats both `config` and `settings` as
    optional patches:
      - field omitted → preserve the on-disk value
      - explicit body value → apply
      - settings: null → clear
    `updateServerSettings` stops reading `existing.config` from the
    in-memory `servers` snapshot, which closes the closure-capture
    hazard where a refresh between debounce-schedule and flush could
    silently revert a separate edit. The route is the single source of
    truth for transport config now. New tests cover settings-only PUT,
    rejected non-object config, and the empty-body no-op patch case.
    The previous "rejects a missing config" test is rewritten to
    document the new no-op-preserve semantics.

(c) Inline comment near the PUT rebuild loop documents that writing
    the full mcpServers map back is what gives the route its desirable
    self-healing property for malformed settings on *other* entries —
    deliberate side-effect, not an accident of normalization.

(d) `flushPendingSettings` surfaces failures via @mantine/notifications
    instead of swallowing them. The modal already closed by the time
    the flush PUT resolves, so a silent fail would leave the user
    thinking their last edits saved (especially painful for the OAuth
    client secret). The notifications wiring was already mounted in
    main.tsx.

Pass-3 (a) — settings form being effectively uncontrolled mid-edit — is
acknowledged in the reply: working as intended today; the proper fix is
internal modal state when file-watching (#1345) forces the issue.

* fix(servers): pass-4 review — strip smuggled settings out of config

Pass-4 review at https://github.com/modelcontextprotocol/inspector/pull/1353#issuecomment-4529861349.

Main finding: `normalizeServerType` spreads unknown keys, so a body
that nested `settings` inside `config` would smuggle a settings field
onto the stored entry without ever passing through `validateSettings`.
Strip the settings key off the incoming config in `buildStoredEntry`
so `validateSettings` remains the single write path for the settings
node — the "one source of truth" invariant pass 2 set up holds again.

Two new tests pin the strip on both routes:
  - POST with `config.settings = { bogus }` lands an entry with no
    settings node on disk.
  - PUT with `config.settings = { bogus }` + `settings: null` clears
    the real settings *and* doesn't re-attach the bogus payload via
    the spread.

* fix(servers): pass-5 review — absorb late connect rejection, tighten validateSettings, log smuggle warning

Pass-5 review at https://github.com/modelcontextprotocol/inspector/pull/1353#issuecomment-4529954490.

Main finding: when the connect-time `Promise.race` lost to the timeout,
the original `this.client.connect(this.transport)` promise was left
pending. After `disconnect()` tore the transport down, real transports
(SSE / streamable-http) would reject that promise later — with no
handler attached, producing a Node `unhandledRejection` (and a vitest
suite warning). Attach a no-op `.catch` right after creating the
connect promise so Node sees the late rejection as handled.

Nit (a): `validateSettings` was casting the raw object through to
`InspectorServerSettings`, which let unknown keys ride along onto disk.
Replaced the cast with an explicit pick-and-build over the known
fields. Unknown stowaways now silently drop on the way through. New
route test pins the behavior.

Nit (b): `buildStoredEntry` now logs a `warn` via the route's pino
logger when an incoming `config` carries a `settings` key. The strip
is still defensive (it isn't a documented contract) but the warning
lets a misconfigured client find out about the wasted field instead
of debugging a silent drop.

Nit (c) — the defensive `?? {}` fallback in `buildStoredEntry` —
acknowledged in the review reply; left in place as belt-and-braces.

* fix(servers): pass-6 polish — scope absorber, thread id, drop empty OAuth, guard `in`

Pass-6 review at https://github.com/modelcontextprotocol/inspector/pull/1353#issuecomment-4529979135. Reviewer signed off as ready; landing the four marginal cleanups since they're all small.

(a) `connectPromise.catch(() => {})` moves inside the
    `if (connectTimeoutMs > 0)` branch. The await-only path propagates
    rejection cleanly through the outer try/catch — the absorber is
    only needed when the race leaves the original promise unattended.
    Code now reads as "absorber is tied to the race," which is the
    real invariant.

(b) Thread `id` (POST id, PUT newId) through `buildStoredEntry` and
    include it in the smuggle warning's pino bindings. Two clients
    smuggling simultaneously are distinguishable in the log instead
    of indistinguishable.

(c) `validateSettings` coerces empty-string OAuth fields to absent.
    The form emits `""` when the user clears an input, and an empty
    `oauthClientId` on disk would later be misread as "OAuth configured."
    New route test pins it.

(d) `buildStoredEntry` adds a null/object guard before `"settings" in
    configObj`. The route layer pre-checks this on POST and PUT, but
    the helper's `unknown` parameter is a weak contract; the guard
    makes it safe to call from anywhere.

* docs(spec): reflect settings persistence + patch-PUT contract in v2_servers_file

The doc was authored when `mcp.json` only stored the server list. Bring it
forward to match what shipped in #1352 / PR #1353:

- Summary calls out that the file also stores per-server settings and
  links into the Per-server settings section.
- On-disk format note explains that `settings` is an optional Inspector-
  specific extension that other MCP tools ignore.
- New top paragraph on the Per-server settings section explains the
  basic-config / settings UI split rationale (simpler form for the
  common case, advanced settings tucked behind a second dialog).
- UI bullet is rewritten to match the patch-style PUT semantics that
  emerged across the review cycle: settings-only and config-only
  PUTs preserve their counterpart inside the write lock, so neither
  modal can silently clobber the other half. The earlier "must
  re-send settings on PUT" hack is gone.
- New bullets capture the save cadence (300ms debounce + flush-on-close
  + failure toast), the patch-PUT contract (omit-preserve / null-clear /
  rename), and the write-path / read-path validator gates.
- Secret storage bullet links to #1356 (OS-keychain follow-up).

* docs(spec): show a third entry with the optional settings node

The On-disk format example demonstrated only basic stdio entries. Add a
streamable-http entry with a populated `settings` node so readers can
see the shape inline rather than having to scroll to the Per-server
settings section. Inline comment in the block cross-links there for the
full contract and notes that other MCP tools ignore the extension key.

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.

- 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.
