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

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

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

parseOAuthPersistBlob already returns null for {} (the server's
missing-file response) and for a literal null body, so the
Object.keys(store).length === 0 guard was redundant — and would throw a
TypeError on a null body before parseOAuthPersistBlob could handle it.
Pass the parsed res.json() straight through.

Review follow-ups on the RemoteOAuthStorage web migration:
- useEmaIdpLoginState.logout(): add a .catch to the now-async
clearEmaIdpSession call so a storage failure no longer surfaces as an
unhandled rejection; leave loginState unchanged on failure (the session
was not actually cleared). Add a test asserting no unhandled rejection.
- createOAuthStore: attach a no-op catch to the eager persistLoadPromise
so a hydration read that fails before any load() awaits it does not
become an unhandled rejection; real awaiters still observe the rejection
via the shared reference.
- storage-remote.test: replace `as unknown as typeof fetch` double-casts
with the typed vi.fn<typeof fetch>() pattern the same PR established.
- remoteOAuthStorage: correct the doc comment to describe the cache-of-one
accurately instead of implying a keyed map.

Serialize persist() in OAuthStorageBase so overlapping remote POSTs cannot
reorder and clobber state. Regenerate launcher package-lock.json to drop
stale zustand entries. Let parseOAuthPersistBlob accept parsed objects
from res.json() without a redundant JSON round-trip.
- transport.ts: update the SSE-branch comment to say the default path uses
fetchWithOptionalAuthIntercept (proxy-aware baseFetch + optional auth-challenge
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.

Address the TypeScript-safety review items on the mid-session auth work:
- oauthManager: replace the unguarded `this.oauthConfig.storage!` assertions on
the EMA re-mint/persist paths with a `requireStorage()` helper that throws a
clear error; in `getOAuthState` reuse the already-narrowed local `storage`.
- cli: `parseRunnerOAuthCallbackUrl` always returns a config, so make
`callMethod`'s `callbackUrlConfig` (and the always-passed `cliAuthOverrides`)
required instead of asserting them non-null at three call sites.
- test-servers/resolve-config: drop the `as unknown as T` double cast; collect
into a base-shaped array and do a single honest downcast at the return.

Extends the header redaction from #1585. Before a fetch entry reaches any
sink, mask known-sensitive credentials in the request/response bodies and
the URL query string, in addition to headers:
- redactBody(): form-urlencoded + JSON bodies, recursive over nested
objects/arrays, best-effort (never throws), values-only.
- redactUrlQuery(): masks sensitive query params, preserves path,
non-sensitive params, and any fragment.
- Sensitive fields: client_secret, code, refresh_token, access_token,
id_token, code_verifier, client_assertion, assertion, password, token
(case-insensitive), reusing the [REDACTED] sentinel.
Applied to the request success + error entries and the async response-body
callback. Live outbound requests are byte-identical — only the logged copy
is redacted.

Round-3 @claude review of #1592 (optional nit): getClientRegistrationKind is
the other synchronous getter that, like getScope, is safe only because its
sole caller (buildOAuthConnectionState) awaits getClientInformation/
getServerMetadata first, flushing hydration before this runs on the
post-redirect callback path. Add a docstring mirroring getScope's so a future
refactor doesn't read it without a preceding awaited storage read.

Round-2 @claude review of #1592 caught a seventh member of the clear
family that the first pass missed: clearClientInformation still wrote to
the store synchronously, carrying the same pre-hydration clobber risk the
clearAfterHydration helper was written for (a clear before hydration lands
persists a near-empty blob, overwriting the whole on-disk oauth.json).
Wrap its mutation the same way and add a clear-before-hydration test
proving a sibling token (and thus every other server's blob) survives.

Address round-1 @claude review of #1592:
- OAuthStorageBase.clear* no longer mutate the pre-hydration (empty) store —
a clear issued before hydration is deferred until it lands, so it merges
onto the real persisted state instead of (a) being resurrected by the late
rehydrate merge or (b) persisting a near-empty blob that clobbers every
other server's on-disk credential. Already-hydrated clears stay synchronous.
- store.setServerState migrates a pre-normalization raw-key blob onto the
canonical key on first partial write (was: shadowed it with a fresh
canonical entry, orphaning the raw blob's other fields). clearServerState
now also drops the raw-key orphan.
- Document the keepalive 64KB combined-body ceiling on the remote-storage
write, the getRemoteOAuthStorage memo key intentionally omitting fetchFn,
and the real ordering invariant behind the sync getScope.
- Tests for the clear-before-hydration and raw-key-migration paths.

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

* refactor(web): update OAuth E2E tests to use new authentication method
- Replaced `runGuidedAuth` with `authenticate` in the InspectorClient OAuth end-to-end tests to support quick authentication with CIMD pre-registration.
- Updated comments to reflect the change in authentication method and its support for HTTP test metadata URLs.
- Ensured that the tests continue to validate the expected authorization URL after the change.
Additionally, imported `ensureCimdClientRegistration` in the OAuthManager to streamline client registration during the authentication process.
* Guided-auth removal, OAuth smoke testing, and TUI/CLI support
* Added CLI OAuth runner flags tests
* Added clarifying comment on port 0 binding
* README notes on TUI oauth callback port, prettier fixes for CLI tests
* CIMD validation uses inline like EMA IdP
* Fixed TUI test failures from merge
* test: bring 5 OAuth files over the 90 per-file coverage gate
The guided-auth-removal work added/touched several files that fell below
the repo's >=90 per-file coverage gate (npm run coverage). CI doesn't run
the gate (it's local-only), so validate + test:integration passed while
these gaps slipped through. Bring them all back over the line:
- core/auth/node/runner-oauth-callback.ts: test bad-URL/non-http-scheme
throws, no-port->80 default, and IPv6 hostname bracketing. Annotate the
provably-dead guards (empty host, out-of-range port, String(err)
fallback, pathname "/" fallback) -- all rejected by new URL() upstream --
with justified v8 ignore comments instead of lowering the gate.
- core/auth/cimd.ts: test the AS-doesn't-support-CIMD early return.
- core/react/useClientSettingsDraft.ts: test the functional-updater path,
the stale-onChange-after-close prev===null guard, and the
timer-fires-after-close value===null guard.
- ClientSettingsForm.tsx: test the CIMD checkbox toggle and CIMD URL clear.
- clients/tui/src/utils/oauthDisplay.ts: test static/dcr registration
kinds, the expired IdP session, and the configured-scope/empty-scope
branches of formatScopes.
npm run coverage now passes (exit 0) across web, cli, tui, launcher.

* fix(web): defer IdP issuer URL error to onBlur in Client Settings (#1544)
The Enterprise-Managed Authorization Issuer field validated its URL inline on
every render, so the 'Must be an http(s) URL' error nagged while the user was
still mid-typing (e.g. before 'https:/…' is complete).
Gate the issuer error display on an issuerTouched flag set onBlur; once
touched it tracks the value live, so the error clears as soon as a valid URL
is entered. The persist gate (canPersistClientSettingsDraft → validateClientSettings)
is unchanged and still validates independently, so an invalid issuer is never
written to the backend regardless of touched state.
Closes#1544

* fix(web): reveal issuer error and block close on invalid issuer (#1544)
Extend the on-blur deferral so an invalid issuer can't be silently dropped on
modal close (the auto-save flush would otherwise discard it with no feedback).
ClientSettingsModal now intercepts its close (X / Esc / overlay): if the issuer
is invalid it reveals the field error (via the form's revealIssuerError prop,
overriding on-blur gating) and keeps the modal open instead of closing. The
user can fix the URL or clear the field — an empty issuer is valid to leave.
The block lives in the modal (unit-tested) rather than App, so App.tsx stays a
thin flush+close that only runs when the close is allowed; the persist gate is
unchanged. Reveal state resets via the modal's open/close remount key.

* fix(core): require a real host in isAbsoluteHttpUrl, not just an http(s) scheme (#1544)
The issuer validation used URL.canParse + an http(s) protocol check, which the
WHATWG parser accepts for bare/degenerate values that aren't actually usable
URLs — e.g. https://foo, https://example, https://. , https://.. all passed.
Tighten the shared rule (used by both the Zod config schema and the form's
inline validation): after parsing and the http(s) scheme check, require the
host to actually look like a host — localhost, an IPv6 literal, or a dotted
domain/IPv4 with at least two non-empty labels. Single-label, bare-dot, and
empty-label hosts are now rejected. Add core tests for the accepted
(dotted/IPv4/IPv6/localhost) and newly-rejected cases.

The Enterprise-Managed Authorization "Issuer" field accepted arbitrary
non-URL text and only failed at save time, surfacing a raw Zod issue array
in "Failed to save client settings" toasts.
- Inline field-level validation: the Issuer input shows a friendly error
("Must be an http(s) URL, like https://idp.example.com").
- canPersistClientSettingsDraft gates on issuer validity (deferring to
validateClientSettings) so an invalid value is never sent to the backend.
- Extract isAbsoluteHttpUrl in core/client/config-parse so the Zod schema
and the form share one http(s)-only URL rule.
- Harden the fallback save-error toast via formatClientConfigLoadError.

* test(web): audit branch-coverage outliers, raise per-file gate to 70 (#1271)
The web per-file coverage gate had drifted red: the recently-landed EMA
auth feature (core/auth/ema/*) and ClientSettings components shipped
undertested, and the prior 50% branch floor let business-logic branches
go untested. CI does not run the coverage gate, so this accumulated.
Add tests to bring every failing file above the gate and push branch
coverage well past 70 across the board, then raise the per-file branches
threshold 50 -> 70 in clients/web/vite.config.ts.
- EMA core (emaFlow, resourceContext, jwt, wire): 50-88% -> 86-100% branch
- EMA OIDC/transport (idpOidc, tokenEndpoint, transportProvider): -> 97-100%
- oauthManager / discovery: 73-83% -> 88-92%
- ClientSettingsModal/Form, ConnectionInfoContent: 0-88% -> 96-100%
- useClientSettingsDraft / useEmaIdpLoginState hooks: 20% -> 100%
- TaskStatusBadge / SortableServerCard outliers: 50% -> 100%
Coverable branches reached by mocking useComputedColorScheme (dark theme),
dnd-kit useSortable (isDragging), and fetch/OIDC paths. Remaining sub-100
branches are genuinely-unreachable defensive guards or happy-dom-inherent
(portal / useMediaQuery / typeof window) and documented in test comments.
No source files changed. Global web branch coverage 88.73% -> 90.63%.
AGENTS.md updated; cli/tui/launcher stay at 50 (out of scope).

* test: raise per-file coverage gate to 90/90/90/90 across all clients
Follows the #1271 web branch-coverage audit (50 -> 70) by raising the
whole per-file gate to >=90 on all four dimensions — lines, statements,
functions, branches — for web, cli, tui, and launcher (core/ is measured
under the web suite). A codebase-wide audit added real tests for every
outlier and brought global coverage up across the board.
Config: all four vitest/vite coverage configs set to 90/90/90/90.
Two pure-type modules (core/mcp/import/types.ts, clients/web/server/
types.ts) added to the web coverage exclude list, matching the existing
type-only exclusions.
Tests: ~50 test files extended/created across core (auth, ema, mcp,
remote, state, storage, react), web components/screens/server, and the
cli/tui clients. Highlights: full EMA OAuth flow + transport coverage,
inspectorClient/remote server backfill, every Mantine control's handler
branches, and the cli unsupported-method / argv-fallback paths.
Genuinely-unreachable branches are annotated at the source with justified
`/* v8 ignore -- <reason> */` comments rather than lowering the gate:
happy-dom-inherent paths (Mantine portal, useMediaQuery, typeof window
SSR guards), React StrictMode effect replay, and provably-dead defensive
guards (?? fallbacks the types make impossible, Select.onChange values
outside the allowed list). No runtime logic changed; the only structural
edits are two behavior-preserving refactors (ResourceTemplatePanel hoists
the field value to a local so the ignore applies in JSX; ToolsScreen
swaps a ternary for an if) and prettier line-wrapping.
Also fixed a flaky real-timer debounce assertion in PromptArgumentsForm
(asserted an exact sibling-typing interleaving that raced the 300ms
debounce; now asserts the load-bearing fact — a non-empty fire-time
sibling capture).
AGENTS.md updated to describe the uniform 90 gate and the v8-ignore
policy. All four client coverage gates, root validate, storybook (370),
and smoke pass.

* test(web): make connect-crash SSE reader stop on the terminal event
`readSseEvents` looped until the server closed the stream (`done`). The
server closes the events stream immediately after writing the terminal
`transport_error`, but under the heavy parallel scheduler pressure of a
full `coverage` run (v8 instrumentation across all workers) that close
can lag far enough behind the event to trip the 30s test timeout — a
hang, not a wrong result. This made the test intermittently fail under
`npm run coverage` (it passed in isolation and under CI's lighter
`test:integration`).
Stop reading as soon as the terminal `transport_error` event arrives
(cancelling the reader) instead of waiting only for `done`. That event is
always the last one the session queue emits, so nothing is lost, and the
test no longer depends on stream-close timing. The `done` break is kept
for any stream that closes first.
Verified green across two consecutive full `npm run test:coverage` runs
(3094 tests) where it previously hung, plus isolation (~0.5s).

Adds enterprise-managed authorization (EMA): browser-side IdP login + RFC 8693 token-exchange and JWT-bearer resource-token mint, per-server EMA opt-in in Server Settings, IdP config in Client Settings, and IdP clientSecret keychain storage. Includes the v2/main merge and review follow-ups (400 on malformed client config; normalizeIdpIssuer import consolidation).
* feat(web,core): edit STDIO cwd/env in Server Settings (#1515)
Persist and edit a STDIO server's working directory and environment
variables through the Server Settings modal.
- Add `env` (pair-array, mirrors headers) and `cwd?` to
`InspectorServerSettings`.
- `storedFieldsToInspectorSettings` lifts the stdio config's `env`/`cwd`
into settings so the modal can show them; they stay on `config` for the
transport. Add `envRecordToPairs` / `envPairsToRecord` helpers.
- `env`/`cwd` remain config-owned on disk (the standard mcp.json location):
the `/api/servers` PUT route writes an edited settings.env/cwd back onto
the stored stdio config on a settings-only patch (supporting clear), and a
config-providing PUT keeps config authoritative. `validateSettings`
accepts `env`/`cwd`.
- Server Settings modal: Working Directory field in Options and a dedicated
collapsible Environment Variables section — both STDIO-only.
- Registry server.json import sets no `cwd` (the schema has no
working-directory concept); documented in serverJson.ts.
Tests: serverList converter round-trip, route write-through (set/clear,
config-precedence, non-stdio no-leak, validation), import preservation
(client-config cwd, registry cwd skip), and form/modal component coverage.

* fix(web): preserve config env/cwd when a settings PUT omits them (#1515 review)
Address Claude's review of #1518.
- `/api/servers` PUT now distinguishes an *absent* `env`/`cwd` (preserve the
stored value) from an explicit empty list / blank string (clear). Previously
`validateSettings` coerced a missing `env` to `[]`, so an env-unaware caller
patching only a timeout would silently wipe the server's env/cwd. The
integrated web client always resends the full GET-rehydrated env, so it was
unaffected — this protects the raw HTTP contract.
- `validateSettings` reports `envProvided`/`cwdProvided`; the write-through only
touches `config.env`/`cwd` for fields the caller actually sent.
- On the omit path, rehydrate the untouched env's keychain values onto the
rebuilt entry so the secret reconcile re-persists them rather than sweeping
the blanked-on-disk keys out of the keychain.
- Minor: guard the stdio cast in `mcpConfigToServerEntries` on the transport
type instead of casting unconditionally.
- Test: settings-only PUT omitting env/cwd preserves config keys + cwd + the
keychain secret.

* test(state): wait for connect refresh before asserting list RPC gate (#1396)
Replace fixed double-microtask flushes in Managed*State connect-path tests with *Change event waits so the capability gate is asserted after refresh completes.
* test(state): fail fast with a readable message if a connect refresh never dispatches its change event (#1396)
The hardened connect-path gate tests now depend on the gated (capability-less /
empty-list) refresh still emitting its *Change event. A future optimization that
skipped that redundant dispatch would make these awaits hang to the vitest
per-test timeout with no clue why.
Extract the per-file waitFor*Change helpers into a shared, generically-typed
waitForChangeEvent() that races the listener against a short timeout and rejects
naming the event that never fired — turning a future hang into a fast, readable
failure. This also removes the duplicated listener/Promise boilerplate across
the five state test files. No production code changes.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* test(state): cover void-detail event resolution in waitForChangeEvent
Add a case asserting the helper still resolves for a signal-only (void-detail)
event — CustomEvent normalizes an absent detail to null, so the listener fires
and resolves rather than hanging. Closes the coverage gap noted in review.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* docs(core): correct TypedEventGeneric void-detail comment to null
CustomEvent normalizes an absent detail to null, so listeners receive null
(not undefined) for void events — as the new waitForChangeEvent void case
establishes. Comment-only; no behavior change.

* feat(web,core): import client configs and registry server.json (#1348)
Wire up the two server-import affordances that were previously todoNoop:
- Import config: source picker (Claude Desktop / Cursor / Cline / VS Code)
read on the backend via a new GET /api/import-source, plus a file-upload
fallback. Per-server review with import/skip on new servers and
overwrite/skip/rename on id conflicts, then a per-server outcome summary.
- Import server.json: parse the MCP registry single-server format
(npm/pypi/oci packages + remotes, env vars, package/runtime args, URL
template vars) into a runnable config, with a file picker and debounced
live validation; Add Server is disabled until validation passes.
Core gains an isomorphic import strategy layer (core/mcp/import) with a
strategy registry, client-config + server.json parsers, a strategy-agnostic
merge, and a dependency-injected source resolver. useServers exposes
importSource(). Modal headers are bold and the redundant server.json section
header is folded into the modal title.

* feat(web): collapse the server.json textarea into a File Contents disclosure
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* feat(web): auto-collapse File Contents disclosure after content loads
Once content is pasted or a file is loaded, collapse the File Contents
disclosure after ~1s with Mantine's built-in accordion animation, signaling
the input was accepted and surfacing the validation/env-var sections. The
disclosure becomes controlled by the modal; clearing the textarea re-opens it.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* feat(web): flash File Contents hover highlight before auto-collapse
Before the File Contents disclosure auto-collapses, paint it with its hover
background for 250ms, then run the collapse over a 325ms animation, so the
collapse reads as intentional.

* refactor(web,core): move import orchestration into core helpers + web hooks
Make the import logic reusable by CLI/TUI and keep the modals display-only:
- core/mcp/import: add parseClientConfig (mcpServers→servers fallback),
resolveServerId, selectServerJsonOption, and buildServerConfigForSelection,
so the full import (parse → select → build → merge) is callable from any
environment.
- core/storage: extract the pure validateStoreId into a Node-free store-id
module (store-io re-exports it) so the isomorphic import layer can validate
ids without pulling Node deps into the browser bundle.
- clients/web/hooks: useServerJsonImport and useImportClientConfig own all the
wizard/parse/debounce/apply state; ServerImportConfigModal and
ServerImportJsonModal are now thin display shells over the dumb panel.

* feat(web): scroll to and highlight a freshly-added server
After a manual add/clone or an import (client config / registry), the new
server's card scrolls into view and draws an animated border (Mantine Border
Animate); clicking anywhere on the card dismisses it.
- App tracks highlightedServerId; addServerHighlighted sets it (edits and
conflict-overwrites don't). Threaded through InspectorView -> ServerListScreen
-> ServerCard.
- ServerCard scrolls into view on highlight and wraps in <BorderAnimate>;
onClick clears the highlight.
- Pin @gfazioli/mantine-border-animate@2.0.3 (Mantine 8 compatible; 2.0.4+
requires Mantine 9).

* fix(web): highlighted card fills its cell and its controls work on first click
- The BorderAnimate wrapper is display:flex, so the card was shrinking to
content width while the border spanned the cell. Stretch the card with
w=100% (and the wrapper).
- Always render BorderAnimate and toggle show/animate instead of conditionally
wrapping: swapping the element type on clear remounted the card, swallowing
the click that triggered it (e.g. the connect toggle fired clear but not
connect, needing a second click). Verified: one click now connects + clears.

* fix(web,core): address review — OCI env, untrack fixture, rename validation
- Untrack the stray inspector-v1-multi.server.json (accidentally committed) and
gitignore root *.server.json fixtures.
- core/mcp/import/serverJson: forward declared env vars into OCI containers via
'-e KEY' docker args (they previously only set the docker CLI process env);
add a test. Clarify buildServerConfig (destructure env out instead of
spread-then-delete) and document value-vs-default env handling.
- useImportClientConfig: validate 'rename' targets inline (invalid charset /
collision with existing, additions, or other renames) and gate the Import
button on canImport; surface the error on the field.

* feat(web): highlight all servers from a batch import, not just the last
Track highlighted servers as a set of ids instead of one. addServerHighlighted

opening an add/import modal starts a fresh batch. Clicking a card clears only
that card's highlight; only the first highlighted card scrolls into view.

* feat(cli): lift config-file headers/timeouts/OAuth into serverSettings (#1482)
The CLI resolved file-sourced servers via resolveServerConfigs(), which
returns bare MCPServerConfig and dropped disk-level headers, timeouts, and
OAuth — CLI connections from a --catalog/--config file silently ignored
them. The TUI already lifted these via mcpConfigToServerEntries().
Extract the TUI's catalog/config -> per-server-settings resolution into a
shared core module (core/mcp/node/servers.ts: loadServerEntries +
selectServerEntry) and route both CLI and TUI through it, so the two share
one file->settings path. --header still overrides the file's headers for
the run while preserving the file's timeouts/OAuth.
- core: add loadServerEntries/selectServerEntry/headersToServerSettings
- tui: tui-servers.ts re-exports the shared core helpers (no logic dup)
- cli: resolve via loadServerEntries + selectServerEntry; drop the
CLI-only conflict check and bare-config path
- tests: core servers.test.ts (settings lifting, header merge/override,
stdio overrides, seed/error/conflict, selection); CLI integration tests
asserting a config header is sent over HTTP and --header overrides it
- docs: CLI README note on file settings being applied
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* refactor(core): address #1500 review — dedup overrides, drop dead wrapper, clearer error, spec refresh
- Remove the now-unused resolveLaunchServerConfigs() wrapper (both CLI and
TUI route through loadServerEntries now); migrate its default-catalog
launch tests to compose withDefaultCatalogPath + resolveServerConfigs.
- Deduplicate applyStdioOverrides against config.ts applyOverrides: export
the latter (now trims cwd) and reuse it in servers.ts.
- selectServerEntry's unknown-name error is source-agnostic ("not found"
not "not found in config file") since entries may be a single ad-hoc
default, where "config file" would mislead.
- Refresh specification/ docs (v2_cli_tui_launcher.md,
v2_catalog_launch_config.md): CLI/TUI resolution now via
loadServerEntries/selectServerEntry; mark gap G1 resolved (#1482);
withDefaultConfigPath → withDefaultCatalogPath.

lift introduced in #1482:
- unknown --server now errors source-agnostically ("not found")
- multi-server catalog selection via --server (and the omit-it error)
- --header merge does not break the stdio connect path
- HTTP transport: a config-file `headers` object is lifted onto the wire,
and a CLI --header overrides it (verified against an in-process test
server's recorded requests via a non-blocking spawn)

* feat(cli,tui): normalize --catalog / --config with web; update --help (#1347)
Bring the CLI and TUI in line with the web catalog vs read-only session
model introduced in #1481/#1483, and close the outstanding --help item
from #1347.
Core (core/mcp/node/config.ts):
- Add `catalogPath` to ServerConfigOptions (writable catalog slot).
- `resolveServerSource()` picks the active source: `--catalog` (writable,
seed-if-missing) wins over `--config` (read-only, error-if-missing).
- Writable sources seed an empty `{"mcpServers":{}}` on first run (matches
the web backend) instead of erroring; read-only `--config` still errors.
- `serverSourceConflict()` shared conflict matrix (mirrors run-web):
--catalog/--config mutually exclusive; neither combines with an ad-hoc
target.
- `readServerListFile()` public loader for runners (TUI) needing the raw map.
- Rename `withDefaultConfigPath` → `withDefaultCatalogPath`; the no-flag
default now fills the writable catalog slot, not --config.
CLI / TUI:
- Add `--catalog <path>` (+ MCP_CATALOG_PATH) and re-document `--config` as a
read-only session in --help.
- Enforce the shared conflict matrix before resolution.
Full writable persistence/CRUD threading remains deferred to #1482 / #1432
(CLI/TUI are read consumers today; the split surfaces as seed- vs
error-on-missing).
Tests: core resolution matrix (source/conflict/seed/read-only), CLI catalog
+ conflict integration tests, TUI loadTuiServers unit tests. READMEs updated.

* test(launcher): add smoke:cli + smoke:tui e2e launcher smokes (#1347)
The launcher smokes only checked `--help` for --cli/--tui; nothing
exercised the launcher → CLI/TUI → core path on the built artifact (only
smoke:web did, for web). Add two end-to-end smokes wired into
validate:launcher between smoke:launcher and smoke:web:
- smoke:cli (scripts/smoke-cli.mjs): runs `--cli` against the bundled
stdio test server via a temp --catalog and asserts tools/list returns
the tools, plus the #1347 resolution paths — default-catalog
seed-on-missing, read-only --config error-without-seed, and the
--catalog/--config conflict.
- smoke:tui (scripts/smoke-tui.mjs): launches `--tui --catalog <temp>`
and asserts the Ink app renders its first frame ("MCP Servers") within
a timeout, then SIGTERMs it (shallow boot/render check).
Both build test-servers/build on demand if missing. Docs updated
(AGENTS.md validate description, launcher README).

* refactor: address review on #1499 (comment accuracy, CLI/TUI flag parity)
Review feedback from @claude on PR #1499 (all non-blocking):
- Align CLI catalogPath resolution with the TUI: `options.catalog?.trim()
|| process.env.MCP_CATALOG_PATH` so an explicit empty `--catalog ""`
falls back to MCP_CATALOG_PATH identically in both front-ends (CLI used
`??`, which only guards undefined/null).
- Clarify the `serverSourceConflict` comment: it mirrors only the
source-selection portion of web's matrix and deliberately omits web's
`--header` rejection, since CLI/TUI merge --header into per-server
settings.
- Note the deliberate --header broadcast semantics in loadTuiServers.
- Share an EMPTY_CATALOG_CONTENT constant between seedEmptyCatalog and
readServerListContent instead of two separate literals.

* feat(web): catalog vs read-only session launch model + apply --header (#1481, #1483)
Per specification/v2_catalog_launch_config.md, `mcp-inspector --web` now selects
the backend's server-list source and a session-wide writability, instead of
seeding an inert `initialMcpConfig` the UI never read:
- `--catalog <path>` (and `MCP_CATALOG_PATH`) → active WRITABLE catalog
(seed/CRUD/watch), like the default catalog.
- `--config <path>` → READ-ONLY session file: served in the UI but never
written, seeded, or plaintext-secret-migrated — safe to point at a foreign
config (e.g. claude_desktop_config.json).
- ad-hoc `--server-url`/command (+ `--header`) → one server held IN MEMORY
(no file written); `--header` is lifted onto the entry so the seeded
connection actually uses it (closes the #1483 warn-only no-op).
- nothing → default catalog (writable), unchanged.
Backend (`createRemoteApp`): new `writable` + `initialServers` options. GET
/api/servers branches three ways (in-memory / read-only file with no
seed+no migrate / writable catalog); the four mutating routes return 403 when
read-only; `/api/config` carries `writable`; the file watcher is skipped for
in-memory sessions. `--catalog`/`--config` are mutually exclusive and neither
combines with an ad-hoc target or `--header`; `--header` requires an ad-hoc
HTTP/SSE server (clear errors otherwise — no silent no-op).
UI: `useServerListWritable` reads `writable` from /api/config; the Servers
screen hides add/edit/clone/remove/reorder/settings and shows a read-only
banner when false. All new props default to writable=true (back-compatible).
Docs: spec gaps G2/G3/G4 updated; launcher README documents the flags.
Verified end-to-end against the built launcher: --config (writable:false,
file byte-stable, mutations 403), ad-hoc --header (in-memory, header lifted),
and --catalog (writable:true, POST persists).

* refactor(web): address review — Mantine <Code> in read-only banner, clarify watcher comment
- Replace raw <code> with Mantine <Code> in the read-only-session Alert
(repo convention: prefer Mantine primitives over raw HTML).
- Add a comment near `watchable` clarifying that a read-only `--config` file
is still watched on purpose (read-only blocks UI writes, not external
observation; `writable` does not gate watching).
Deferred (per reviewer): consolidating useSandboxUrl + useServerListWritable
into one useConfig hook to avoid the duplicate /api/config fetch — optional
follow-up. The redundant ad-hoc header type-guard is kept as defensive.

* fix(core): make "error" the canonical terminal status on a mid-session crash (#1490)
On a real mid-session transport crash many SDK transports fire BOTH
`onclose` and `onerror` in a transport-dependent order. The `onclose`
guard (`if status !== "disconnected"`) let a trailing `onclose`
downgrade a crash's `"error"` status back to `"disconnected"`, so the
persistent terminal status differed by ordering:
- onerror-then-onclose → "disconnected"
- onclose-then-onerror → "error"
`onclose` now treats `"error"` as terminal (only `"connected"`/
`"connecting"` → `"disconnected"`), so `"error"` is the canonical resting
status in both orderings. It still emits the `disconnect` event exactly
once so session-teardown consumers fire identically either way.
Because the state managers gated list/message/subscription/task teardown
on `getStatus() === "disconnected"`, holding the status at `"error"`
would have left them stale in the onerror-first ordering — swapping one
ordering-dependence for another. Introduce `isTerminalStatus()`
(disconnected || error) and key every teardown guard off it so they
clear identically regardless of crash ordering.

* fix(core): single disconnect event when explicitly disconnecting from "error" (#1490 re-review)
Addresses the non-blocking observation from the PR review: explicitly
calling disconnect() from a held-"error" status could fire the
`disconnect` event twice. close() can trigger the transport's onclose
synchronously; onclose (holding status at "error") fired `disconnect`,
then disconnect()'s own guard saw status still != "disconnected" and
fired it again — a timing-dependence on whether the SDK closes sync.
Add a `disconnecting` ownership flag: onclose defers its status set +
`disconnect` event to disconnect() while it is set, so the
explicit-disconnect path emits exactly one `disconnect` regardless of
sync/async close. Crash-path onclose (flag unset) is unchanged.

* test(core): deterministically pin the sync-close disconnect double-fire (#1490 re-review)
The real-stdio test asserts the single-disconnect invariant but may not
exercise the sync-close branch (the one that double-fired) if the SDK
stdio transport closes asynchronously. Add a test that overrides the SDK
client's close() to invoke the transport's onclose synchronously,
forcing the exact timing the `disconnecting` flag guards. Verified it
asserts 2 (fails) without the flag and 1 (passes) with it.

Closes#1323. Adds an `error`-event-driven `lastError` on useInspectorClient and a mid-session failure toast in App.tsx; the transport onerror is scoped to non-handshake (status !== connecting) so handshake failures stay on the connect() rejection path. Follow-up: #1490.
Ports the CLI, TUI, and launcher from v1.5 into v2 behind a single
`mcp-inspector` entrypoint (launcher → web/cli/tui). Includes the
`mcp-inspector --web --dev` launcher fix (Vite alias resolution + prod-server
double-start), the root `postinstall` install cascade with simplified CI, and
spec/AGENTS docs (no-workspaces rationale, Development setup).

* fix(core): trace dropped fetch body update when entry rotates out (#1390)
FetchRequestLogState.onFetchRequestBodyUpdate silently dropped a deferred
response-body update when the matching entry had already been evicted by
log rotation (>= maxFetchRequests newer requests appended between the
append and the fire-and-forget body read). The user saw an empty Response
Body with no way to distinguish "body never came back" from "body dropped
after eviction".
Plumb an optional pino logger into FetchRequestLogState (defaulting to the
silent logger) and emit a logger.debug at the early-return site so the drop
is traceable. The web client wires the existing remote logger from
createWebEnvironment into the state manager.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* fix(core): emit dropped-body trace at warn level so it is observable (#1390)
Review feedback: the web remote logger (createRemoteLogger) defaults to
level 'info' with no override at the environmentFactory call site, so a
logger.debug at the drop site is filtered out by both the pino level gate
and transmit.level — the diagnostic never reaches /api/log and the drop
stays invisible in the shipped web app, defeating the issue's goal.
Promote the trace to logger.warn (>= info, so it transmits by default). A
response body lost to log rotation is unexpected data loss, not routine
diagnostic noise, so warn is the appropriate severity. Update the comment
to explain the level choice and switch the test stub from debug to warn,
extracting a small typed makeWarnLogger helper per review.

* feat(web): configurable Network Log Size per server + body-dropped toast (#1390)
Turn the otherwise-invisible "response body dropped after rotation" case into
an actionable signal:
1. Per-server `maxFetchRequests` setting (default 1000, 0 = unlimited),
editable as "Network Log Size" in the first (Options) accordion section of
the Server Settings form. Plumbed through the full settings pipeline:
InspectorServerSettings + StoredMCPServer types, the serverList disk
converters (read defaults to 1000, write omits the default to keep diffs
minimal — 0 is a meaningful non-default), and the node server's GET-sanitize
+ write-side validateSettings (non-negative number). Applied live to the
active connection on settings-modal close via a new
FetchRequestLogState.setMaxFetchRequests (shrinking trims immediately), and
at connect time for the next session.
2. FetchRequestLogState now emits a `fetchRequestBodyDropped` event, but only
for genuine rotation drops (log at capacity with a finite cap) — not for
benign post-clear stragglers or unlimited logs, which previously also hit
the warn path. App shows a deduped, persistent toast (stable per-server id,
no auto-close) explaining what happened and the likely causes, with a link
that opens this server's settings on the Options section (modal remounts via
key) so the user can raise the limit if it's just a high-traffic server.

* fix(web): don't treat a cleared Network Log Size field as unlimited (#1390)
Review feedback: clearing the NumberInput emits "", and `parseInt("") || 0`
coerced that to 0 (unlimited). Since the value applies live on modal close, a
user who cleared the field to retype and then closed the modal would silently
switch the log to unlimited. Fall back to the current value on an empty/NaN
parse and reserve 0 for an explicit numeric entry. Adds a cleared-input test.

* fix(web): send a cancellation notification when cancelling an ordinary tool call (#1458)
The Tool detail panel's Cancel button was a silent no-op for ordinary
(non-task) tool calls: App.onCancelToolCall found no captured taskId and
did nothing, leaving the button looking actionable while the call ran on.
Wire request cancellation through the MCP cancellation flow. callTool now
tracks the in-flight call with an AbortController whose signal is threaded
into the SDK request options; aborting it makes the SDK send a
notifications/cancelled for that request and reject the pending call.
cancelToolCall() performs the abort. callTool surfaces the cancellation as
a ToolCallCancelledError (without recording a failed call), which App
clears as a clean cancel plus a short confirmation toast.
Task-augmented calls are unchanged: they have a server-side task and are
still cancelled via cancelRequestorTask (#1457).
Closes#1458

* fix(web): address review — distinguish disconnect from cancel; tidy callTool params
Review follow-ups on #1463:
- Disconnect no longer surfaces as "Tool call cancelled". The catch in
callToolWithRetries now throws ToolCallCancelledError only when the abort
reason matches the deliberate user-cancel reason (TOOL_CALL_CANCELLED_REASON);
a disconnect aborts the same controller with a different reason and falls
through to the normal error path, so no misleading toast.
- Note the activeToolCallAbortController slot is shared (last-writer-wins)
across all callTool callers.
- Fold callToolWithRetries/attemptToolCall's long positional parameter list into
a single ToolCallRequest object; move the URL-elicitation loop state into
callToolWithRetries.
Adds an integration test that a disconnect mid-call rejects as an ordinary
error (not ToolCallCancelledError), using a slow send_progress call over HTTP.
