Same fix as TaskControls: pass null instead of undefined to Mantine
Select value prop so the clear button disappears on first click.

Add ajv as an explicit dependency in clients/web/package.json (was only
available transitively via @modelcontextprotocol/sdk). Add inline comment
on StdioServerConfig.type explaining the implicit-default contract and
its impact on switch narrowing.

clients/web/tsconfig.app.json's include pulls in ../../core/**/*.ts.
TypeScript module resolution from those files walks up from core/mcp/
looking for node_modules, which lands at the repo root. CI only ran
npm install inside clients/web/, so root node_modules was empty and
core/mcp/types.ts / elicitationCreateMessage.ts / taskNotificationSchemas.ts
failed to resolve @modelcontextprotocol/sdk/types.js and zod/v4
(locally the build worked because root had been manually installed).
Add an explicit root npm install step before the clients/web install.

Stands up the type-only prerequisites for the v2 UX component
interfaces refactor per specification/v2_ux_interfaces_plan.md.
Phase 0.1 — MCP SDK dependency:
- Add @modelcontextprotocol/sdk ^1.29.0 and zod ^4.3.6 to both the
root package.json and clients/web/package.json so component files
can import Tool / Prompt / Resource / Task / LoggingLevel / etc.
directly from the SDK.
Phase 0.2 — Inspector wrapper-types module:
- Create core/mcp/types.ts mirroring the type-only subset of v1.5's
core/mcp/types.ts: MCPServerConfig (discriminated union), ServerType,
MCPConfig, ConnectionStatus, StderrLogEntry, MessageEntry (Date
timestamps, not ISO strings), FetchRequestEntry(+Base), ServerState,
and the *Invocation types. Adds v2-only wrappers
InspectorResourceSubscription and InspectorServerJsonDraft.
- Add core/mcp/taskNotificationSchemas.ts for the Inspector-owned
notifications/tasks/list_changed signal (not in the SDK).
- Add core/mcp/elicitationCreateMessage.ts re-exporting ElicitRequest
and ElicitResult plus an InspectorPendingElicitation interface for
typing the pending-queue.
- Add core/json/jsonUtils.ts for the shared JsonValue / JsonObject
types used inside core/mcp/types.ts.
- Copy v1.5's clients/web/src/utils/jsonUtils.ts (JsonSchemaType) and
schemaUtils.ts (AJV-backed validators) verbatim so SchemaForm can
switch off its local JsonSchema type.
- Copy v1.5's clients/web/src/lib/types/customHeaders.ts verbatim for
ServerSettingsForm and the experimental panel.
- Add clients/web/src/types/navigation.ts with InspectorTab (UI-routing
concept, lives with the web client rather than in core/).
- Wire tsconfig.app.json + vite.config.ts with the @inspector/core/*
path alias so component files can import from core/ without
relative-path hell.
Phase 0.3 — Vet (likely) hedges in v2_ux_interfaces.md:
- Follow-up sweep on commit 2ef257da. Replaces the remaining
useMcpClient references with useInspectorClient, ties pending
elicitation / sampling callbacks to the in-InspectorClient queue
rather than a non-existent useElicitation / useSampling hook,
corrects Task references to the SDK type (not an InspectorTask
wrapper), corrects log hook wiring to useMessageLog, and strikes
all remaining v2-only hooks with explicit "no v1.5 analog"
annotations. grep "likely" specification/v2_ux_interfaces.md now
returns zero results.
Phase 0.4 — Local-redeclaration inventory:
- specification/v2_ux_interfaces_phase_0_4_inventory.md enumerates
every ad hoc local type (JsonSchema, LogLevel, TaskStatus,
PromptItem, ResourceItem, ToolListItemProps, RootEntry, KeyValuePair,
inline ConnectionStatus / transport unions) that will be replaced
in Phases 1–4, including the file it lives in, every site that
re-imports it, and the SDK / wrapper type that replaces it. Intended
for the Phase 0 PR description and as a running checklist during
the refactor.
Build state: npm run build / lint / format:check all pass in
clients/web.

The interfaces doc was produced by parallel research subagents that
were instructed to prefix uncertain hook names with (likely) rather
than fail to fill in a section. The result is 52 instances of "likely"
in v2_ux_interfaces.md, almost all attached to hook names that were
never cross-checked against v1.5/main. Several are actively wrong:
- useTools / usePrompts / useResources do not exist in v1.5; the
actual hooks are useManagedTools / useManagedPrompts /
useManagedResources.
- useTasks does not exist; v1.5 has useManagedRequestorTasks (and
Task itself is a raw SDK 1.x type, not an Inspector wrapper).
- useMcpClient does not exist; v1.5 has useInspectorClient.
- useLogs conflates three v1.5 hooks: useMessageLog, useStderrLog,
useFetchRequestLog.
- useHistory does not exist; v1.5 uses useMessageLog as the history.
- useElicitation / useSampling / useRoots do not exist as discrete
React hooks in v1.5; those flows are handled inside InspectorClient
via SDK request handlers.
- useServerCapabilities is not a separate hook; capabilities live on
useInspectorClient's result.
- Appendix A's "v1.5 bundles primitive logic in App.tsx" claim is
wrong about v1.5 in this repo; that's true of upstream
modelcontextprotocol/inspector v1.x mainline, not v1.5/main here,
which has the full core/react/* split.
Adds Phase 0.3 to walk every (likely) instance and either resolve it
against v1.5 source or strike it, with a confirmed rename table and
explicit definition-of-done (zero "likely" matches in
v2_ux_interfaces.md after the pass). Adds Risk #11 capturing the
underlying rule: hedging words next to type/hook/file claims must be
vetted before a planning doc ships.

Adds specification/v2_ux_interfaces_plan.md, the implementation plan
for the component interface refactor scoped in v2_ux_interfaces.md.
Uses the v1.5/main branch of this repo as the source of truth for
Inspector-owned wrapper types (MCPServerConfig, ConnectionStatus,
MessageEntry, FetchRequestEntry, StderrLogEntry, ServerState, the
*Invocation cache types) and pins @modelcontextprotocol/sdk at the
latest 1.x line (^1.29.0). Includes a name-mapping table that
translates the Inspector* placeholders in v2_ux_interfaces.md to
v1.5's actual type names.
Plan organizes the work into phases: foundations (SDK + wrapper
types), elements, group+screen feature clusters (folded together to
keep the build green at every commit), views, and a cleanup sweep.
Calls out the discovered ServerCard auto-connect useEffect violation
to fix in-place during the server cluster, and flags that Task is
already exported by the SDK 1.x so the InspectorTask wrapper framing
in v2_ux_interfaces.md is stale and needs a follow-up correction.

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.

Adds specification/v2_ux_interfaces.md, a plan for aligning the web
client's dumb components with the MCP schema (2025-11-25) and the
Inspector core hook layer. The document inventories every component in
clients/web/src/components/ (elements, groups, screens, views),
records current props, identifies MCP schema touch points, proposes
target prop interfaces, and maps callbacks to the v1.5 core hooks that
will supply them. Includes an appendix on how v1.5 core returns a
deliberate mix of raw SDK types and Inspector-owned wrappers.
Also threads an "Interfaces" link into the submenu of all v2_ux*
specification documents so the set cross-links consistently.

Replaces inline style and opacity prop on ServerCard with a new
'disabled' variant on the Card theme, per AGENTS.md rules against
inline styles on components. Also picks up prettier formatting on
ResourcesScreen.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- ToolControls and PromptControls now manage searchText as local state
and filter their lists internally (matches on name + title/description)
- Removed searchText/onSearchChange props from ToolsScreen, PromptsScreen,
and their associated stories
- HistoryListPanel search now also matches against stringified response
payloads
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- Rename StatusIndicator to ServerStatusIndicator across all files
- ServerCard: add activeServer/onSetActiveServer props for coordinated
connection flow — when a card's toggle is switched on, it sets itself
as the active server, shows "Connecting" status, and dims all other
cards (opacity + pointerEvents none + inert for full keyboard blocking)
- ServerListScreen: manage activeServer state internally, pass to cards;
switch to full-width layout with 3-column grid and scrollable card area
- ServerCard: move "Test Client Features" dropdown above ContentViewer
with min-height row for consistent card heights
- ToolResultPanel: move Clear button to top-right header row
- ToolDetailPanel: right-align Execute Tool button, size md, not full-width
- ListChangedIndicator: bump Refresh button to size sm
- ToolsActive story: expand to 30 tools with titles
- UnconnectedView stories: all servers disconnected, remove Connecting story

ResourceControls now manages its own search state internally and filters
all three accordion sections (URIs, Templates, Subscriptions) by name
and URI. Added ListToggle to expand/collapse all sections. Moved Export
JSON and Clear All buttons from HistoryControls sidebar to the
HistoryListPanel header for better proximity to the data they act on.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- Extract ResourceControls group component from ResourcesScreen:
title, search, list-changed indicator, and three-section accordion
(URIs, Templates, Subscriptions) with per-panel ScrollArea.Autosize
- Refactor ResourcesScreen to sidebar+panel Flex layout matching
HistoryScreen/LoggingScreen pattern (ScreenLayout, Sidebar, SidebarCard)
- Each accordion panel dynamically computes max height based on how many
sections are open, dividing available space evenly
- Accordion uses controlled state (value/onChange) to track open sections
- Sidebar card sizes to content naturally (compact when collapsed,
grows with open sections, capped by scroll areas)
- Right panel wrapped in ScrollArea.Autosize for long content
- Add AllSections story with 20 URIs, 7 templates, 8 subscriptions
- Add more templates and subscriptions to ConnectedView ResourcesActive
- Add ResourceControls stories (Default, WithSearch, Empty)
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- Redesign TaskCard to match v1 Task Details panel layout:
header with task ID + status badge + cancel button,
always-visible summary row (Status, Last Updated, Created At, TTL)
with Expand/Collapse button, expandable section with status message,
progress bar, error, and Full Task Object JSON viewer
- Add TaskControls group: search input + status filter dropdown +
Refresh/Clear History buttons (mirrors HistoryControls pattern)
- Add TaskListPanel group: scrollable panel with ListToggle for
expand/collapse all, splits tasks into Active/Completed sections
with counts, filters by search text and status
- Refactor TasksScreen to sidebar + panel layout matching HistoryScreen:
manages search/filter state internally, flat tasks array
- Simplify TaskCard callbacks to just onCancel
- Extract named .withProps() subcomponents (HeaderLeftGroup,
HeaderRightGroup, SectionTitle, SummaryRow, DetailRow) for
AGENTS.md compliance
- Update all stories (TaskCard, TaskControls, TaskListPanel,
TasksScreen, ConnectedView)
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- Rename ResourceTemplateInput to ResourceTemplatePanel with panel layout
(title header, URI with live variable preview, labeled inputs, Read Resource button)
- ResourceTemplatePanel manages its own variable state via useState;
single onReadResource(uri) callback returns fully resolved URI
- Extract ResourceSubscribedItem group component with name, timestamp, and
subtle Unsubscribe button
- Add hover state to listItem variant via theme classNames + App.css pseudo-selector
- Add Refresh button to ResourcePreviewPanel
- Refactor ResourcesScreen callbacks: onSelectUri, onSelectTemplate,
onReadResource, onSubscribeResource, onUnsubscribeResource replace
per-item onClick/onUnsubscribe props; screen wires callbacks to children
- Define data-only types (ResourceItem, TemplateListItem, SubscriptionItem,
SelectedResource, SelectedTemplate) separating data from callbacks
- Extract named .withProps() subcomponents (FooterRow, AnnotationGroup,
ActionGroup, Spacer) for AGENTS.md compliance
- Update all stories (ResourceTemplatePanel, ResourcesScreen, ConnectedView)
