* feat(web): add per-server Roots config + client roots capability (#1425)
Add MCP roots support to the v2 web Inspector as a per-server config
section in the server settings form (no separate Roots tab/screen).
- Persistence: add `roots: Root[]` to `InspectorServerSettings` and
`StoredMCPServer`; thread through serverList converters (lift on read,
drop empty-uri rows / blank names on write, omit when empty) and the
remote server's read-side drop guard + `validateSettings`.
- Capability: `setupClientForServer` always advertises the roots
capability (`roots: cleanRoots(savedSettings?.roots ?? [])`) so the
server can issue `roots/list` and receive `roots/list_changed`.
- Live apply: edits to a connected server's roots are pushed via
`inspectorClient.setRoots(...)` once, on settings-dialog close — diffed
against the client's current roots — rather than per keystroke, to
avoid flooding the server with `roots/list_changed` / `roots/list`.
- Form: new Roots accordion section with a required URI and an optional
name per row (unlike v1, which was URI-only), + Add Root, and remove.
Tests cover the persistence round-trip (serverList + servers-route),
the form/modal section, and reuse the existing InspectorClient
roots/`setRoots` integration coverage.

* refactor(roots): address review — dedup guards/cleanRoots, preserve extra fields, test live-apply
Responding to the PR #1431 code review:
- Dedup `isRootArray`: drop the copy inside `validateSettings` and reuse the
module-scope guard the read path uses, so the two can't drift
(core/mcp/remote/node/server.ts).
- Dedup the clean-roots normalizer: hoist a single exported `cleanRoots`
into core/mcp/serverList.ts and reuse it from both
`inspectorSettingsToStoredFields` and App.tsx (drops the local copy).
- Preserve non-form root fields (e.g. `_meta`): `cleanRoots` now spreads the
carried-through fields and only normalizes uri/name, and the modal's
`handleRootChange` spreads the existing root on edit — so a hand-edited
root's `_meta` survives load + persist + edit instead of being silently
dropped.
- Test the App live-apply-on-close path: new App.test.tsx cases assert
setRoots is called once with cleaned roots when changed on the active
server, and not called when the cleaned roots already match what the
client advertises. Adds a cleanRoots unit test (blank drop + _meta
preserve).

Wires the ported Tasks screen + core task subsystem through App.tsx: sticky Clear Completed, cancel/refresh error toasts, core-side per-task progress correlation, Run-as-task on the Tools screen (gated on server support), per-server Task TTL, and live task-status toasts.
* feat(web): tool progress toasts + persist tool selection/result across navigation (#1414)
Surface incoming notifications/progress as toasts so the user can watch a
long-running tool's progress without leaving the tool view — the v2 replacement
for v1's always-visible "Server Notifications" shelf. Toasts are keyed by
progress stream and updated (not stacked) per tick so a chatty server updates
one toast rather than flooding the corner. Progress notifications still land in
the History tab via the existing transport-level tracking.
Companion change: lift the selected tool and its form values into App.tsx
alongside the already-lifted toolCallState, make ToolsScreen controlled, and
drop the clear-on-unmount effect. Leaving the Tools tab and returning now
preserves selection, inputs, and result. All three reset together on
disconnect via resetSessionScopedUiState, preserving the #1368/#1394 behavior.

* feat(web): persist per-screen selection/search/filter across navigation (#1417)
Lift every screen's selection, form, search, and filter state out of the
screen components into session-scoped state owned by App, passed down as
controlled props. The screens unmount on tab switch, so this is what keeps
the user's context in place when they navigate away and back within a live
session. State is cleared only on disconnect (resetSessionScopedUiState) or
an explicit user action — never on plain navigation.
Lifted per screen:
- Tools: sidebar search (selection/form/result were lifted in #1414)
- Prompts: selected prompt, argument values, submitted marker, search
- Resources: selected resource/template URI, originating-template marker,
search, accordion open-sections
- Apps: selected app, form values, search (running/maximized stay local —
they're tied to the live iframe/bridge that is torn down on unmount)
- Tasks: search + status filter
- Logs: filter text + visible-level set
- History: search + method filter
- Network: filter text + visible-category set
The four sidebar *Controls (Tool/Prompt/App/Resource) become controlled for
search; ResourceControls also controls accordion open-sections. Level/category
default maps move to logLevels.ts / fetchCategories.ts so the screen files
keep a single component export.
Pagination already persists (it lives in the App-level Paged*State managers),
so no work was needed there.

* feat(web): persist list scroll position across navigation + reset tests (#1417)
Add useScrollMemory: a module-keyed hook that remembers a Mantine ScrollArea's
offset across unmount/remount (the screens unmount on tab switch). Scroll lives
in a module-scope map rather than threaded App state — it's ephemeral DOM state,
and threading ~16 more props would balloon the surface for no benefit. App calls
clearScrollMemory() in resetSessionScopedUiState so offsets clear on disconnect
alongside the lifted selection/filter state.
Wired into the four main list panels (Logs, History, Network, Tasks) and the
Tools/Prompts/Apps sidebar lists. Pagination already persists via the App-level
Paged*State managers.
Tests: useScrollMemory unit test (save/restore, key isolation, clear), and the
App disconnect test now also exercises representative lifted UI state (tool
search, prompt selection, log filter) clearing on disconnect.

* refactor(web): collapse per-screen lifted state into one {screen}Ui object
Replace the ~46 individual selection/search/filter props threaded App →
InspectorView → screen with one `{screen}Ui` object + one `on{Screen}UiChange`
setter per screen (8 pairs). Each screen reads its fields from `ui` and updates
via `onUiChange({ ...ui, field })`; the in-flight result panels
(toolCallState / getPromptState / readResourceState) stay separate since
they're written by App's async action handlers, not the screens.
The `*UiState` interfaces live with their screens; the empty-state defaults are
gathered in screenUiState.ts so the screen files keep a single component export
(react-refresh), mirroring logLevels.ts / fetchCategories.ts.
Trims InspectorView's prop surface substantially and keeps the persistence
behavior identical. Tests/stories collapse their stateful wrappers to a single
ui object; added Tools/Tasks/History interaction tests to keep per-file
coverage above the gate.

* fix(web): dismiss visible progress toasts on client teardown (#1414 review)
The progressNotification effect cleanup cleared its id-tracking set but left
on-screen "Tool progress" toasts to auto-close up to 5s later — they could
linger into the next session, and the lingering toast's onClose could delete an
id from the new session's set and trigger a duplicate-id re-show. Hide each
tracked toast in cleanup so both gaps close. Addresses @claude review note #2.

* feat(web): clear the tool result when a different tool is selected
The Tools result panel renders `toolCallState` regardless of which tool is
selected, so selecting a new tool used to leave the previous tool's result
showing beneath it. Route tools UI changes through an App handler that drops
`toolCallState` whenever `selectedToolName` changes; search/form edits keep the
selection (and the result) intact. Tests cover both the clear-on-switch and
keep-on-search paths.

* feat(web): render pending sampling/elicitation requests (#1407)
Server-initiated sampling and elicitation requests never reached the v2
web UI: the InspectorClient queued them and returned a Promise that only
resolved on a user response, but nothing subscribed to the pending-change
events or rendered the (already-built) request components. A tool that
triggered one spun the Execute button forever.
Wire the queues to the UI:
- Add usePendingClientRequests() (core/react) subscribing to
pendingSamplesChange / pendingElicitationsChange and returning the live
arrays. Expose getPendingSamples() / getPendingElicitations() on
InspectorClientProtocol (and the test fake) so hooks can read them.
- Add PendingClientRequestModal, an App-level modal that surfaces one
queued request at a time (sampling-first) via the existing
SamplingRequestPanel / ElicitationFormPanel / ElicitationUrlPanel. It is
non-dismissable so the blocked call only resolves via an explicit action.
- Wire it in App.tsx: responding/rejecting resolves the client's handler
Promise, which unblocks the originating call and clears the spinner.
Also fold in two issues surfaced while verifying:
- SchemaForm rendered an `array` + `items.enum` (multi-select enum) as a
JSON textarea because only `items.anyOf` had a branch; add a MultiSelect
branch with enumNames label support.
- ToolsScreen's result lives in App and outlived the screen's local
selection (reset on tab-switch unmount), leaving a result with no
selected tool. Clear the result on unmount for a clean slate on return.
Prompts/Resources gate their preview on selection, so they are unaffected.

* fix(elicitation): support explicit decline; honest queue label; review polish
Address @claude review on #1411:
- Add an explicit "Decline" action to ElicitationFormPanel so the spec's
decline (refusal) is distinguishable from cancel (dismissal); the JSDoc
claimed accept/decline/cancel but only accept/cancel were wired. Wire the
modal body to emit { action: "decline" }.
- Replace the misleading "1 of N" queue label (the leading 1 never changed
since the modal always shows the head) with an "N pending" hint, hidden when
nothing else is queued.
- Make the dead useMemo honest: derive the head request inside the memo from
the source arrays so it actually caches (the inline activeElicitation had a
fresh identity every render).
- Document the URL elicitation accept-on-open semantic with a comment pointing
at the follow-up (#1415).
- Add an App-level round-trip test driving pendingSamplesChange end-to-end
(modal opens, respond() fires, empty event closes it).
Follow-ups filed: #1415 (URL two-step completion flow), #1416 (form required-
field submit gate + double-submit guard).

* fix(elicitation): include untouched schema defaults in submitted content
The schema form displays a field's default via resolveValue(), but onChange
only writes a field into `values` once the user edits it. So an elicitation
submitted with default-only fields left untouched dropped them entirely —
v2 sent just the manually-edited fields while v1 sent defaults too (reported
with the everything server: firstLine/integer/number/enum defaults missing).
Add collectSchemaDefaults() to jsonUtils (recurses nested objects, omits
fields with no default) and seed ElicitationFormModalBody's values state with
it via a lazy initializer. The modal body is keyed by request id, so it
re-seeds per request; user edits still override seeded defaults via the
existing onChange merge.
Tests: collectSchemaDefaults unit tests (field types, nested, empty) in
jsonUtils.test; a modal test asserting an untouched-default form still submits
its defaults in content.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* fix(forms): seed schema defaults for tool-call and app-launch forms too
Extend the elicitation defaults fix (collectSchemaDefaults) to the other two
SchemaForm consumers that own form state and submit it: ToolsScreen (tool
execute args) and AppsScreen (app launch args). Both reset formValues to {} on
selection, so default-only fields the user never edited were dropped from the
submitted args — same root cause as the elicitation modal.
Seed formValues from the selected tool/app inputSchema defaults on select.
User edits still override via the existing onFormChange merge.
(InlineElicitationRequest has no consumers wired up, so it's left as-is.)
Tests: ToolsScreen sends a tool's default on Execute without editing;
AppsScreen sends an app's default on Open App without editing.

* feat(elicitation): gate form submit on required fields; guard double-submit (#1416)
Fold the #1416 hardening into this PR:
- Gate the elicitation form's Submit button on required fields. Promote the
hasMissingRequiredFields helper out of AppDetailPanel into jsonUtils (shared)
and use it in ElicitationFormPanel so Submit is disabled until every required
field has a value.
- Guard against double-submit. Add an optional `busy` prop to the sampling,
elicitation-form, and elicitation-url panels that disables their responding
actions. PendingClientRequestModal's bodies use a new ref-guarded
useRespondOnce() hook: the first action dispatches and locks the panel; later
clicks no-op. This stops a fast double-click from calling respond()/reject()
twice (which throws and produced an unhandled rejection). Copy URL stays
enabled — it doesn't resolve the request.
Tests: hasMissingRequiredFields unit tests; ElicitationFormPanel submit-gate
and busy-lock tests; a modal double-click-resolves-once test.

* fix(tools): cap detail/result panels at viewport and scroll internally
The Tools screen's detail and result columns sized to their content and bled
past the bottom of the viewport on long output (e.g. the env dump or a long
elicitation result). Cap each column at the screen's available height and let
its panel scroll internally instead.
- ToolsScreen: drop `align: flex-start` and wrap each column in a stretched
`ContentPane` (Flex column, capped by `mah` = viewport − header − xl*2). The
pane's definite height is what lets the card's inner ScrollArea know how far
to shrink — a bare `mah` on the card does not (the card sizes to content, so
the scroll region renders full-height and overflow:hidden just clips it,
unreachable). Mirrors the proven Prompts/Resources preview panes.
- ToolResultPanel: pinned header + inner ScrollArea (flex 0 1 auto, mih 0).
- ToolDetailPanel: pinned title/annotations header, scrolling body
(description + form + progress), pinned Execute footer.
Audited the other screens: Prompts/Resources already use this pattern,
ServerList and the four list panels (Logging/Network/History/Tasks) already cap
via ScrollArea.Autosize. Only AppsScreen's app-input form had the same gap —
fixed it the same way: AppDetailPanel now scrolls internally and the card uses
variant="preview" so the running app's iframe and a long form both stay within
the viewport.
Verified in-browser against the everything server: the get-env result now
stops at the viewport bottom with margin and scrolls within the card
(clientHeight 502 vs scrollHeight 1931), header pinned.

* test(remote): use sync pino destinations in logging tests to fix teardown race
CI flaked with an uncaught `ENOENT: ... /tmp/inspector-log-unknown-level-*/app.log`
that failed an unrelated later test. The remote-logging integration tests create
`pino.destination(logFile)` loggers (async sonic-boom streams) and rmSync the temp
dir in finally/afterEach without closing the stream — a buffered background flush
then fires after the dir is gone and throws an uncaught error, which Vitest counts
as a run failure even though all tests pass.
Make those destinations `sync: true` so the write lands during the request instead
of on a later flush, removing the race. Test-only; unrelated to this PR's feature
work but it was blocking the PR's CI.

* fix(app): clear per-call panels and log level on disconnect (#1368)
Session-scoped UI state owned by App.tsx — the Tools / Prompts /
Resources result panels (`toolCallState` / `getPromptState` /
`readResourceState`) and the optimistic `currentLogLevel` — survived a
disconnect/reconnect cycle, so server B's screens showed server A's last
result. Extend the existing `disconnect` listener to reset all four back
to empty / "info", alongside the activeServerId + modal-flag resets it
already does. This covers all three disconnect paths the listener handles
(explicit toggle, header Disconnect button, mid-session transport
failure). `latencyMs` continues to reset via the connectionStatus effect.
Adds App.test.tsx covering the disconnect → tool-call-panel-cleared and
log-level-reset transition, mocking the InspectorClient (a fake
EventTarget), the per-server state managers, the core hooks, and
InspectorView.

* test(app): assert all four panels reset on disconnect (#1368)
Address PR review: the disconnect test asserted only toolCallState and
currentLogLevel. Extend the InspectorView double with prompt/resource
status spans and get-prompt/read-resource buttons so the test fills and
then asserts the reset of all four pieces of session-scoped state
(tool / prompt / resource panels + log level), fully matching the
"reset on disconnect" contract. Retitle the test accordingly.
