Connect over Streamable HTTP (2025-06-18, stateful or stateless), legacy HTTP+SSE (2024-11-05, auto-detected), or stdio (desktop only). Browse and call tools, resources, and prompts; subscribe to resource updates; inspect notifications, progress, and a JSON-RPC timeline. Auth, headers, and params reuse the REST editors; tool/prompt arguments and results use the shared code editor and response viewer (body, headers, timing). Activity is mirrored to the Console. +- **Bidirectional MCP**: the client answers `sampling/createMessage`, `roots/list`, and `elicitation/create` so you can test servers that call back. +- **OAuth 2.1 for MCP**: metadata discovery, Dynamic Client Registration, PKCE S256, client-credentials, refresh, and an OAuth debugger log. Interactive authorization-code is desktop-first (loopback); the browser uses paste/non-interactive grants. +- **Sample-server MCP mock**: `POST /mcp`, `POST /mcp/authed` (Bearer + API key), legacy `GET /mcp/sse`, OAuth-protected `POST /mcp/secure`, and `sample-server --stdio` with deterministic tools (`echo`, `add`, `fail`, `slow`, triggers). + +### Changed + +- MCP workspace uses the same request/response split as HTTP.

If the first token looks like a path (`/` or `\`), resolve it against the process working directory once if that file exists. +4. Otherwise spawn the token as given.
