Codebase-wide sweep bringing the web client into strict compliance with the AGENTS.md TypeScript and Mantine/React conventions: ~170 inline 2+-static-prop elements extracted to named .withProps() constants across ~77 files, the AGENTS.md rule wording tightened to match (static-prop boundary + Accordion/Transition/data-*/Box exemptions), a real ScreenStage Box->Flex layout regression fixed (direction: column) with a Storybook regression guard, and an App.tsx double-cast tightened. Closes#1762.
* feat(web): single header MonitoringToggle + Prompts-style Tools results (#1661)
Consolidate the monitoring column's open/close affordances into one header
toggle, and align the Tools/Prompts result panes and the sidebar log layout.
- Add a single `MonitoringToggle` in the header, to the right of the theme
icon. It opens/closes the monitoring column and only shows when a server is
connected OR a connect attempt failed (wide viewport + a monitor tab
available) — the same availability rule the column uses.
- Remove the scattered pin/close icons: delete `PinColumnButton`; drop `onPin`
from the Logs/Protocol/Network/Console screens and their stream panels; drop
`onOpenMonitor` from the server list; remove the close button from
`MonitoringControls`/`MonitoringScreen`.
- Tools screen: remove the "Results will appear here" placeholder pane. Results
now replace the input form in a single content pane (the Prompts pattern),
with a top-left X (ToolResultPanel) that dismisses them back to the form;
form values are preserved for a re-run.
- Prompts screen: the argument form fills the content pane width (drop the 40%
cap), matching the Tools input.
- LogEntry: add a `compact` two-line layout (time/level/logger on line one,
message wrapping below) used by the embedded monitoring-column Logs.

* polish(web): tooltips on icon buttons + rename "monitoring column" → "monitoring sidebar" (#1661)
- Add Mantine `Tooltip`s to the icon-only controls: Client settings, Theme
(dynamic light/dark label), the monitoring-sidebar toggle, the list-level and
per-entry Expand/Collapse toggles, the Pin/Unpin toggle, and the Replay
button. Labels mirror each control's existing aria-label.
- Rename the feature term "monitoring column" → "monitoring sidebar" across the
user-facing labels (Open/Close/Resize), comments, and tests, so the UI calls
it a sidebar consistently.

* review: consistent sidebar wording + reuse MonitoringToggleProps (#1661)
Address the two optional notes from the PR #1662 review:
- Make the MonitoringToggle JSDoc voice consistent ("sidebar" throughout,
no lingering "column").
- Drop ViewHeader's duplicate `MonitorToggleProps` and reuse the element's
exported `MonitoringToggleProps` as the single source of truth.

* feat(web): slide-in/out animation for the monitoring-sidebar toggle (#1661)
The header MonitoringToggle now animates in/out via a Mantine Transition whose
in/out styles drive width + margin-left (plus opacity/translateX): as its slot
grows from 0 → the 36px icon, the flex-end header row reflows and pushes the
theme + client-settings buttons one slot to the left; the exit reverses and they
slide back over. A negative margin-left while collapsed cancels the row gap so
the theme icon stays flush-right when the toggle is absent. Only appearance/
disappearance (connect / disconnect / narrow viewport) animates — opening or
closing the sidebar leaves the toggle in place.

Make the server-list toolbar's expand/collapse toggle and open/close-monitoring
icons the same width and spacing as the header's theme / client-settings icons:
- ListToggle (default variant), PinColumnButton, and the MonitoringControls
close button now render as `ActionIcon variant="subtle" size={36}` (glyph 20),
matching the header's 36px ActionIcons, instead of wider `Button`s.
- ServerListControls uses `gap="sm"` so its buttons sit the same 12px apart as
the header's RightSection controls.
Update a TaskListPanel test that found the toggle by a brittle
`mantine-Button-root` class to select it by its accessible name instead.

* feat(network): add Network screen surfacing backend fetch log (#1355)
Routes `FetchRequestLogState` to a new Network tab so users can inspect
HTTP-layer request/response headers, status, duration, and category
(auth vs transport) of every fetch the backend makes for an active
session. Adds `NetworkControls` + `NetworkStreamPanel` + `NetworkEntry`
groups, a `monoBreak` Text theme variant for long header values, and
wires onClearNetwork / onExportNetwork (JSON download) from `App.tsx`.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* fix(network): include request / response bodies in search filter
Headers were already covered but bodies were not, so searches for
strings that live inside the JSON-RPC payload (e.g. "jsonrpc",
"initialize", a tool name) silently returned no matches.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* fix(network): always render Response Body section, note streaming
Streaming responses (text/event-stream, application/x-ndjson, POST to
/mcp) are intentionally not body-captured by the fetch tracker, so the
section was silently omitted. Now whenever a response was received we
render the section, with either the body, a "(empty)" note, or a
"Streaming response — body not captured" note keyed off content-type.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* fix(network): capture response bodies via async body-update events
Two related fixes:
1. The fetch tracker was marking every streamable-HTTP POST /mcp call as
"not captured" because the response content-type is text/event-stream.
In practice those streams are bounded — the server sends the
JSON-RPC reply (sometimes preceded by progress events) and closes —
so we can clone the body and read it. Only GET + SSE / ndjson is the
unbounded long-lived channel that has to stay uncaptured.
2. Reading the body inline blocked the transport from processing
progress notifications until the entire stream finished, breaking the
`resetTimeoutOnProgress` integration test. The body is now read in
the background and dispatched via a new `fetchRequestBodyUpdate`
event that the FetchRequestLogState patches into the matching entry
by id. Plumbing wires through node/transport, the remote SSE channel
(RemoteSession, RemoteClientTransport), and the remote event types.
Also hides the Network tab when the active server is stdio (no HTTP
traffic to surface) and bumps the inline body preview limit to 100 KB
so typical tools/list responses render rather than tripping the "too
large" notice.

* feat(network): show orange SSE badge for long-lived stream entries
Adds a small "SSE" badge to the right side of the NetworkEntry header
(left of the HTTP status badge) when the response is a long-lived
streaming channel (GET + text/event-stream or application/x-ndjson) —
the only case where the body genuinely isn't captured. Makes the
"not captured" placeholder less surprising at a glance.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* fix(network): address PR review findings
- Stop capturing OAuth response bodies (drop updateResponseBody from the
effectiveAuthFetch tracker). Restores pre-PR behavior for auth-category
entries so live access_token / refresh_token values can't leak into the
Network tab body preview during a screen-share. Headers + status are
still tracked.
- Extract `isLongLivedStreamResponse(method, contentType)` to
core/mcp/fetchTracking so the rule lives in one place; consumed by the
tracker and the NetworkEntry UI placeholder.
- Document the intent of NetworkEntry's `useEffect` (the list-level
toggle is authoritative; per-entry overrides are intentionally
discarded on each list toggle).
- Rename MAX_INLINE_BODY_BYTES → MAX_INLINE_BODY_CHARS (`.length` is
UTF-16 code units, not bytes) and update the user-facing notice.
- Switch NetworkStreamPanel's search from joined-string `.includes` to
per-field `.some(.includes)` so a term can't span field boundaries.
Regression test added.
- Add aria-label to ListToggle ("Expand all" / "Collapse all") — both an
a11y improvement and a stable selector that lets the panel test stop
fishing the button out by text-content negation.

* test(network): use ListToggle aria-label in panel + modal tests
Cleanup spotted in PR review follow-up:
- HistoryListPanel + ServerSettingsModal previously fished the ListToggle
out by empty text content because the toggle had no accessible name.
Now that ListToggle exposes "Expand all" / "Collapse all", both tests
can use getByRole + name and the stale comments go away.
- ListToggle's own tests now assert the aria-label contract so a future
refactor can't silently drop it.

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

* test(coverage): bootstrap vitest unit infra and add tests at 90%+ per file (#1245)
Establishes the unit-test runtime AGENTS.md mandates: a vitest "unit"
project alongside the existing storybook project, RTL + jest-dom +
happy-dom, a Mantine-aware render helper, and a 90%-line per-file
coverage gate enforced by CI. Adds 66 test files covering all 62
components under elements/groups/screens/views, plus core/mcp and
clients/web/src/utils. Total: 577 tests, 98.7% line coverage globally.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* test(coverage): address PR #1269 review feedback
- AGENTS.md: correct coverage gate description (lines ≥ 90, statements ≥ 85,
functions ≥ 80, branches ≥ 50) with rationale for the relaxed branch
threshold
- InspectorView.test.tsx: document what the Math.random() mock values
(0.1 / 0.99) control vs. STUB_SUCCESS_RATE in InspectorView.tsx
- vite.config.ts / tsconfig.test.json: drop unused `globals: true` and the
`vitest/globals` type now that every test file imports describe/it/expect/vi
explicitly; manual `afterEach(cleanup)` in setup.ts remains required because
testing-library auto-cleanup relies on globalThis.afterEach

Wraps every section of ServerSettingsForm (Connection Mode, Custom
Headers, Request Metadata, Timeouts, OAuth Settings) in a controlled
Mantine Accordion. The accordion is driven by new required
`expandedSections` / `onExpandedSectionsChange` props so the parent
owns expand/collapse state — consistent with the dumb-component
principle.
Adds a `variant?: "default" | "subtle"` prop to ListToggle. In subtle
mode it renders as an ActionIcon with `variant="subtle"`, `color="gray"`,
and a 16px icon so it visually matches Mantine's CloseButton in modal
headers (transparent until hover).
Adds a WithSettingsModal story on UnconnectedView that presents the
form inside a Mantine Modal with a custom three-column header: subtle
ListToggle on the left (expands/collapses all sections at once),
"Server Settings" Title centered, CloseButton on the right.
