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.

Version 0.17.3 had TypeScript build errors that prevented successful builds. This patch release fixes those errors and bumps the version to 0.17.4.

- bump @modelcontextprotocol/sdk to ^1.20.1
* In client/package.json
- bump @vitejs/plugin-react to ^5.0.4
- bump vite to ^7.1.11
* In package-lock.json
- bump playwright to 1.56.1
- cascading changes to rollup and other dependencies
Add npm override to lock get-intrinsic to version 1.3.0, preventing
upgrades to 1.3.1 which requires the generator-function package.
The generator-function package is not available in Anthropic's internal
Artifactory, causing installation failures when users run
`npx @modelcontextprotocol/inspector` and npm resolves to get-intrinsic@1.3.1.
This override ensures all installations use get-intrinsic@1.3.0 which does
not have the generator-function dependency.
- New feature: Connection Type
- Reverts "fix: filter out client_secret when storing OAuth client information"
- Fixes STDIO "Headers is undefined" message when connecting to an SSE server.
- in createCustomFetch function
- convert finalHeaders to headers object for node-fetch compatibility
- for SSE streams, convert node stream to response body to web ReadableStream since EventSource polyfill expects web-compatible stream
* In package-lock.json and package.json
- add node-fetch as a dependency
This fixes#600
- set TS SDK to 1.17.5, which has the automatic log level handling
* In useConnection.ts
- push the logging/setLevel message onto the message history stack so it is clear in the Inspector that it has been sent.
- Install husky and lint-staged dev dependencies
- Configure pre-commit hook to run prettier on staged files
- Only format changed files to improve performance
- Prevents CI formatting failures by formatting locally
* pass resource in auth debugger, reusing server url
* throw error on resource url mismatch to match regular auth flow
* lint & tests
* add test
* make authserver url make more sense
* use latest typescript sdk
* more lenient resource checking
* pick resource, and store in state
* fixing tests and types
* [auth] use sdk function for selecting resource (#537)
* use sdk function
* bump typescript sdk
* fix some tests
Since merging the latest changes from `main` that put auto-open back in when running the start or dev scripts, the `test:e2e` run results in the Inspector being opened in the browser. This change suppresses that (tested locally). Thanks, @cliffhall!

- Unified start.js to handle both dev and production modes with --dev flag
- Generate session token in parent process, pass via MCP_PROXY_TOKEN env var
- Enable browser auto-open even when authentication is enabled by including token in URL
- Auto-reloads now work seamlessly with persistent tokens across hot reloads
- Simplified npm scripts - dev and dev:windows now use the same unified script
- Better developer experience with consistent token handling
The token is generated once per session and remains stable through server/client
reloads, making development smoother while maintaining security.
