* Logging: per-request log level on modern servers (era fork) (#1629)
On modern (2026-07-28) servers `logging/setLevel` and the session-scoped
level are gone: the client opts into logs per request via the
`io.modelcontextprotocol/logLevel` `_meta` key, and the SDK does not
attach it automatically, so server logs are silently absent until stamped.
Core (`InspectorClient`):
- `setModernLogLevel(level | undefined)` / `getModernLogLevel()` store the
opt-in level; `mergeMeta` stamps it on every outgoing request, gated on
the negotiated modern era so legacy connections are untouched.
- Cleared on disconnect so it can't leak into the next connection.
Web UI:
- `LogControls` forks on `protocolEra`: legacy keeps the `logging/setLevel`
selector + Set button; modern shows a per-request opt-in Select (Off +
levels, applied immediately) with copy explaining logs arrive on the
originating request's stream.
- Threaded `protocolEra` / `modernLogLevel` / `onSetModernLogLevel` through
LoggingScreen and InspectorView from App.
Tests: unit coverage for the modern LogControls/LoggingScreen fork;
integration coverage proving the `logLevel` `_meta` is stamped on a real
modern server once opted in (and not on legacy).

* test-servers: logging era-fork showcase configs + proof screenshots (#1629)
Add two manual-testing configs and README docs for the logging era fork:
- logging-legacy-http.json: plain streamable-HTTP server with `logging: true`
and a `send_notification` tool. The Logs tab shows the legacy session-scoped
"Set Active Level" selector + Set button; calling the tool streams logs.
- logging-modern-http.json: same, with `transport.modern: true`. Connect with
Protocol Era = Modern and the Logs tab shows the per-request opt-in control;
the client stamps `_meta["io.modelcontextprotocol/logLevel"]` on every
request (visible in the Network tab request body).
pr-screenshots/ documents the verified behavior end-to-end against both real
servers: the legacy control with logs streaming, the modern per-request
control, and the modern tools/call request body carrying the stamped logLevel
_meta.

* test-servers: send_notification emits via per-request notifier so modern logs stream (#1629)
The `send_notification` tool sent its `notifications/message` through the
global `server.server.notification()`. On the modern (2026-07-28) stateless
leg that isn't tied to the in-flight request, so the SDK answered the tool
call with plain JSON and dropped the log — nothing reached the Inspector's
Logs panel.
Prefer the per-request `extra.sendNotification` (rebuilt from
`ctx.mcpReq.notify`): scoped to the current request, it makes the SDK upgrade
the response to SSE and stream the log back on the originating request's
stream. Falls back to the global notifier (legacy path / no per-request
context). Verified end-to-end: opting in via the Logs-tab "Log Level per
Request" control and calling send_notification now streams the entry on the
modern server; legacy behavior unchanged (server-notification integration
tests green).
README documents the modern logging showcase and the caveat that this test
server streams whenever a tool emits — the SDK beta strips the per-request
envelope from the handler context, so the tool can't gate on the client's
logLevel opt-in (the client-side `_meta` stamp #1629 owns is still fully
visible in the Network tab).

* test-servers: send_notification uses SDK request-scoped log() → spec-faithful modern gating (#1629)
The previous fix routed `send_notification` through `extra.sendNotification`
(`ctx.mcpReq.notify`), which streams on the modern leg but emits
unconditionally — the log showed up even when the client hadn't opted in via
the per-request `logLevel`.
The SDK already provides the correct primitive: `ctx.mcpReq.log(level, data,
logger)` (added in `McpServer.buildContext`). It applies the era-correct
threshold gating itself — on the modern (2026-07-28) leg it reads the
per-request `logLevel` opt-in from the request envelope and drops the message
when the client didn't opt in or the level is below the requested severity; on
legacy it honors the session level from `logging/setLevel` — and emits through
`notify`, so the modern response still upgrades to SSE and the log rides the
originating request's stream.
Surface it as `extra.log` (`toHandlerExtra` maps `ctx.mcpReq.log`) and have
`send_notification` prefer it, falling back to the global notifier for callers
without per-request context. Verified end to end: opting in via the Logs-tab
"Log Level per Request" control stamps `logLevel` in the request `_meta` and
streams the log; setting it back to Off omits the key and the server gates the
log (plain JSON response, no notification). Legacy server-notification
integration tests still green. (No SDK change needed — the earlier apparent
gap was our test server using the wrong low-level API.)

* web+core: add "Log Level per Request" as a per-server setting, defaulting to on (#1629)
Adds the modern per-request log level as a persisted Server Settings option
(Options → "Log Level per Request", below Protocol Era), so a server can opt
into logs by default instead of the Logs-tab control starting at Off.
- types.ts: `ModernLogLevel` (`"off"` | the 8 levels), `DEFAULT_MODERN_LOG_LEVEL`
= "debug" (default-on so a modern connection surfaces server logs out of the
box), `MODERN_LOG_LEVELS`, and an `isModernLogLevel` guard. Field added to
`InspectorServerSettings` and `StoredMCPServer`.
- serverList.ts: round-trip the field (lift on read, omit-on-default on write,
drop unknown literals) mirroring `protocolEra`; add to the persisted field
allowlist.
- remote/node/server.ts: validateSettings accepts/validates it and the
normalize path drops a malformed literal.
- inspectorClient.ts: the constructor seeds `modernLogLevel` from the setting
(`"off"` → not opted in), so a modern connection stamps the level from the
first request without UI interaction. mergeMeta still gates on the modern era.
- ServerSettingsForm/Modal: a Select (Off + 8 levels) with a modern-era
description. App seeds the live Logs-tab control from the setting on connect
so the two stay in sync.
Tests: form Select (default/onChange/off/reflect), modal handler, serverList
round-trips, route validation (accept/reject/drop), and constructor seeding
(seeded level stamped from the first request; "off" opts out). The prior
modern-era "stamps once set" test is updated for the new default-on behavior.
Coverage gate green.

* Fix CI + review: format ServerSettingsForm, drop stray network export, broaden ignore
- Prettier-format ServerSettingsForm.tsx (the format:check failure that broke
CI — my pre-push `npm run format` from the repo root was a silent no-op since
there is no root format script; formatting is per-client).
- Remove `inspector-network-logging-modern-2026-07-19T15-11-27.013Z.json`, a
Network-tab export debugging artifact accidentally committed in ca2aa526
(flagged by review).
- Broaden the .gitignore debugging-artifacts section with
`/inspector-network-*.json` so future network exports are ignored (the
existing `/inspector-history-*.json` didn't match the network export naming).
Verified with the full `npm run ci` (validate → coverage → smoke → storybook),
green across all clients.

* test: add modern-era log delivery + gating e2e tests (#1629)
The modern-era suite covered the client-side `_meta` logLevel stamp but not
that a log actually flows back — the legacy suite already has that
(`should receive server-initiated notifications via SSE/streamable-http`), so
the modern side was the gap.
Add two live e2e tests against a modern (`createMcpHandler`) server serving the
`send_notification` tool with `logging: true`:
- opted-in (server setting = a level): calling the tool delivers a
`notifications/message` over the request's SSE stream, with the right
level/logger/data.
- not opted in (setting "off"): the tool still returns a result, but the server
gates the log — no `notifications/message` is received.
This exercises the full path end to end: the client seeding + `_meta` opt-in,
and the server's `send_notification` → `ctx.mcpReq.log` era-correct gating.
Verified with the full `npm run ci` (green across all clients).

* web: hide the modern "Log Level per Request" setting on legacy connections (#1629)
The per-request log level is meaningless on a legacy server (which uses
logging/setLevel), so hide it in Server Settings when the era is legacy:
- protocolEra pinned to "legacy" → hidden (no connection needed), or
- protocolEra "auto" that negotiated legacy at connect time → hidden.
It stays visible for a pinned "modern" server, and for an "auto" server that is
either not yet connected (era unknown) or resolved to modern.
Threads the negotiated era down: App passes `negotiatedEra` to
ServerSettingsModal only when the settings target is the live-connected server
(`connectionStatus === "connected" && settingsModalTargetId === activeServerId`);
the modal forwards it to ServerSettingsForm, which gates the control on
`configuredEra === "modern" || (configuredEra === "auto" && negotiatedEra !== "legacy")`.
Tests: visibility matrix on the form (legacy hidden; auto+legacy hidden;
auto+unconnected and auto+modern and modern shown) and a modal hide case; the
existing modern-log tests now base on a modern-era settings object. Verified in
the browser (legacy hides, switching to modern reveals it reactively) and with
the full `npm run ci` (green across all clients).

* 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.

* 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): 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.

collapse reads as intentional.

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.

'-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.

* test(cli,tui): add in-process source coverage gates (#1484)
CLI and TUI source had no coverage gate: CLI tests spawned the built
binary out-of-process (coverage never saw clients/cli/src) and the TUI
had only two smoke tests. Regressions there were invisible to CI.
CLI:
- Rewrite __tests__/helpers/cli-runner.ts to invoke runCli() in-process
(capture process.std*.write, map thrown errors to an exit code),
preserving the CliResult shape so all existing tests run unchanged and
clients/cli/src is now measured under v8 instrumentation.
- cli.ts: program.exitOverride() so a commander usage error throws
(catchable in-process) instead of tearing down the worker; --help /
--version still exit cleanly. Drop the dead, never-imported main().
- Add a thin out-of-process e2e.test.ts that spawns the built binary for
the shebang / process.exit paths the in-process runner can't reach.
- Add @vitest/coverage-v8, a per-file gate (90/85/80/50) excluding only
src/index.ts (binary bootstrap), and pool: 'forks' for capture
isolation. cli.ts lands at ~98% lines / 100% functions.
TUI:
- Add @vitest/coverage-v8 and an interim per-file gate over the
non-React logic (logger.ts, components/tabsConfig.ts, utils/*); the
Ink components, App.tsx, and hooks/ are excluded with a documented
follow-up (#1501). Add tests covering the included modules (100%).
Wiring + docs:
- CI runs each client's test:coverage; root test:cli / test:tui (used by
validate) and root test:coverage now enforce the gates.
- gitignore clients/**/coverage; update AGENTS.md and client READMEs.

* docs(cli): clarify in-process runner footguns from PR #1502 review
Review notes on the in-process CLI test runner (no behavior change):
- Warn in runCli's docblock that --help/--version must NOT go through the
in-process runner: exitOverride only re-throws non-zero exits, so exitCode
0 falls through to process.exit(0) and would kill the vitest worker. Those
belong in the out-of-process e2e.test.ts layer.
- Document that a timeout orphans the uncancellable invokeCli promise (its
stdio subprocess stays alive; later writes hit the restored stdout) — a
known, acceptable trade-off on the hang-only failure path.
- Fix a stale reference to the removed main() (errors now route through
index.ts).

* feat(web): expandable resource_link with read-on-demand (#1449)
Replace the placeholder `resource_link` rendering in ContentViewer with a
dedicated, Mantine-native `ResourceLink` element that mirrors V1's behavior:
- Shows uri (monospace, link-styled), optional name/description, and a
mimeType badge.
- Expand/collapse affordance (chevron + loading spinner) that is keyboard
accessible (native button: role, aria-expanded, aria-label, Enter/Space).
- On first expand, reads the linked resource on demand via an injected
callback and renders the full read result inline as formatted JSON under a
green "Resource:" label, capped to a max height with scroll for large
results. The fetched result is cached across collapse/expand.
The read handler is threaded as a "dumb component + callback as prop" through
ToolResultPanel → ToolsScreen → InspectorView, with App supplying a handler
that returns the `ReadResourceResult` from `inspectorClient.readResource`.
Also extract the shared `resourceContentsToBlock` helper into
`utils/resourceContents.ts` (previously private to ResourcePreviewPanel).
Tests: unit coverage for ResourceLink (collapsed/expanded/error/cache) and
the ContentViewer wiring, plus Storybook stories with play functions.

* fix(web): scroll large resource_link read results within the card
A plain ScrollArea with only `mah` does not scroll when its parent (the
content-sized card) has no definite height, so a large read result overflowed
the card instead of scrolling. Switch to ScrollArea.Autosize, which grows with
content up to the max height and then scrolls. Adds a LargeResult story
covering the bounded-scroll behavior.

* refactor(web): make ResourceLink a group; extract ResourceLinkInfo element
ResourceLink is stateful (expand/loading/cached result) and fetches data via
a callback — group-like behavior, and the only `elements/` component using
useState. Move it to `groups/` and split out the pure-display metadata as a
new `elements/ResourceLinkInfo` element (uri/name/description/mime + an
optional action slot).
This keeps the layer dependencies clean (no element→group import, which
moving ResourceLink alone would have introduced):
- ContentViewer (element) renders ResourceLinkInfo (element) statically for
`resource_link` blocks and no longer takes an onReadResource prop.
- ToolResultPanel (group) renders the interactive ResourceLink (group) for
`resource_link` blocks, ContentViewer for the rest.
- ResourceLink (group) composes ResourceLinkInfo + ContentViewer.
Also reverts the now-single-consumer resourceContents.ts extraction, restoring
ResourcePreviewPanel's local toContentBlock.

* fix(web): make ResourceLink read retryable and guard double-fetch
Address PR review: a failed read is no longer cached as terminal — only
a successful result is cached, so collapsing and re-expanding retries the
read after a transient failure. Add a loading guard so toggling while a
read is in flight does not fire a redundant second read.

* feat(web): wire the listChanged indicator across all screens (#1402)
The per-screen list-changed indicator was hardcoded false in
InspectorView for Tools, Apps, Prompts, and Resources, so it could
never light up. Source it from the managed-state layer instead.
Each ManagedXState now tracks a listChanged flag: set true when its
*/list_changed notification arrives (the existing auto-refresh leaves
it set), exposed via getListChanged()/a listChangedChange event, and
cleared by clearListChanged() or on disconnect. The useManagedX hooks
surface the flag and clear it on a user-initiated refresh (the
indicator's Refresh button = acknowledge). App threads the three flags
to InspectorView, which maps them to the screens — Apps shares the
tools flag since apps are a filtered view of tools.
Tests cover set/clear/disconnect at the state-manager layer, the hook
subscription + refresh-clears behavior, and the InspectorView routing
(including Apps sharing the tools flag and no cross-wiring between

* fix(core): close clear-after-await race in managed-list refresh (#1402 review)
The useManagedX refresh() callbacks cleared the listChanged flag AFTER
awaiting the fetch. If a */list_changed arrived mid-fetch, the state
re-set the flag (and auto-refreshed), then the trailing clear wiped that
genuinely-new signal. Clear BEFORE the await instead: the user's refresh
acknowledges only the change in hand, and a mid-fetch change re-sets the
flag and survives. Adds a race regression test on the tools hook.

* fix(web): drop duplicate Refresh on the Apps screen (#1402)
AppControls uniquely had a standalone toolbar Refresh button AND the
ListChangedIndicator on a separate row, so once the indicator could
actually appear (this PR), the Apps screen showed two Refresh buttons.
Match the other three controls (Tools/Prompts/Resources): the indicator
is the single header-right refresh affordance. Updates AppControls and
AppsScreen tests to assert exactly one Refresh (and none when the list
hasn't changed).

* feat(core): stop auto-invoking */list on list_changed; user pulls via Refresh (#1402)
With auto-refresh on, the list was already current by the time the
list-changed indicator appeared, making its Refresh button moot. Now the
managed Tools/Prompts/Resources state managers only flag the change on
*/list_changed (they no longer auto-refresh); the list stays as-is until
the user clicks Refresh, which fetches the new list and clears the
indicator. The connect-time initial load is unchanged.
Resource templates (no own indicator, part of the Resources screen) also
stop auto-refreshing; onRefreshResources now refreshes both resources and
templates, since a single resources/list_changed covers both. Tasks are
left auto-refreshing — they have no list-changed indicator and need live
status updates.

* docs(core): correct ManagedResourceTemplatesState header comments (#1402 review)

* feat(web): add per-server 'Auto Refresh on List Changed Notifications' option (#1402)
New Options section in ServerSettingsForm with a single checkbox. When
checked, the managed Tools/Prompts/Resources (and resource templates)
state auto-refreshes on */list_changed notifications; when unchecked
(default) the notification only lights the list-changed indicator and the
user pulls via Refresh.
Plumbing: new optional autoRefreshOnListChanged on InspectorServerSettings
and StoredMCPServer, round-tripped through serverList (lifted with a false
default, persisted only when true, added to the exhaustive field-key map);
surfaced from InspectorClient via a new getServerSettings() on the protocol;
the state managers read it live at notification time to decide auto-refresh
vs flag-only. Resource templates re-subscribe to their list_changed but only
auto-refresh when the option is on (they have no indicator of their own).
Tests cover the round-trip (true persists, false omitted), the form
section (render/checked/toggle), and each state manager's on/off branch.

* fix(server): persist autoRefreshOnListChanged through validateSettings (#1402)
The PUT /api/servers write path runs settings through validateSettings,
which rebuilds the value from explicitly-named fields and silently drops
unknown keys — so autoRefreshOnListChanged never reached disk (the
serverList round-trip test passed because it calls
inspectorSettingsToStoredFields directly, bypassing this path). Validate
it as an optional boolean and include it in the built value; false is
omitted on disk by inspectorSettingsToStoredFields as before.
Adds integration tests over the real PUT path: true persists, false is
omitted, and a non-boolean is rejected (400).

* feat(web): default the Server Settings modal to the Options section (#1402)
Open 'Options' instead of 'Custom Headers' when the Server Settings modal

assertions, the three header tests (now expand 'Custom Headers' first since
it's no longer open by default), and the story defaults.

* 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

* 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.

* 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.

Stops `git add -A` from re-staging the `*.png` files Claude Code drops

subdirectories (e.g. `clients/web/public/`) still get tracked when
explicitly added.
Also untracks the two screenshots that slipped through previously

Clear / Export / Copy All on the Logging screen were rendered with the

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).

full contract and notes that other MCP tools ignore the extension key.

* feat(test): run v1.5-ported integration tests under node-env vitest (#1307)
Adds an `integration` vitest project alongside `unit` and `storybook` so
the 13 v1.5-ported tests that need real HTTP/stdio servers (or fail under
happy-dom's SDK mock resolution) run again under node env with 30s
timeouts. Restores test-servers/ as a buildable package so the stdio
subprocess spawns a real .js file. Drops the v1.5-source `coverage.exclude`
globs and fills coverage gaps across the v1.5-ported core/ modules; two
large files (inspectorClient.ts, remote/node/server.ts) keep narrow
per-file excludes tracked in #1310.

resolution, and we already pass `--noCheck` from `test-servers:build`.
Under TS 6+ the deprecated `baseUrl` exited with code 2, which
silently skipped vitest in the `&&` chains of test:integration /
test:coverage / validate.
- Rework the "send() throws after closed" test to drive `closed` via
an actual transport_error SSE event instead of mutating private
state through a cast — matches the real path the branch guards.
