External MCP clients (Cursor, Windsurf, Copilot) can now drive clide. The
MCP server's tools/list is generated from the co-registered command+schema
registry (D-74) that already feeds the CLI and palette — the full
mcp__clide__* namespace with no hand-maintained second surface (D-86). Each
command's CommandSchema maps to a JSON-Schema inputSchema; tools/call routes
mcp__clide__<cmd> to dispatcher.dispatch and renders the IpcResponse as MCP
content (data as JSON, errors with isError).
register() gains a mcpExpose flag (default true); pane.tail opts out as a
poor request/response fit. tail/events are server-intercepted so they're
naturally absent. The two /ide stubs (getDiagnostics, executeCode) are left
as stubs — making them real (analyzer hook, Jupyter eval) is out of scope
per the ticket. Transport unchanged (SSE, D-73).

Seventh slice of T-99. clide now advertises itself to Claude Code's
/ide command and serves a working MCP endpoint over HTTP+SSE per
D-73 (the Q-33 transport decision, locked in this commit).
What lands:
* D-73 — MCP transport for /ide is SSE over HTTP. Resolves Q-33;
references D-68 + D-72.
* lib/src/ipc/mcp_server.dart — McpServer class. localhost HTTP
listener on a random port; GET /sse opens a long-lived SSE stream
with an initial endpoint event carrying the session id; POST
/messages?sessionId=... accepts JSON-RPC requests and replies via
the matching SSE stream. JSON-RPC handlers for initialize,
tools/list, tools/call.
* Discovery file at $HOME/.claude/ide/<pid>.lock with the workspace
+ url so `/ide` can find us. Removed on stop.
* The two /ide minimum tools (mcp__ide__getDiagnostics,
mcp__ide__executeCode) ship as stubs — real implementations need
the analyzer integration / a clide eval surface, both follow-ups.
* main.dart starts the MCP server alongside the unix IPC server on
daemonClientFactory and project switch. Failure non-fatal — the
UI runs without MCP.
* 12 server tests cover lifecycle (start/stop, lock file), unknown
paths, full JSON-RPC round-trip for all four methods, error
responses, and edge cases (unknown session, malformed JSON,
notification without id).
The "Claude Code's /ide discovers and connects" smoke is deferred to
T-131 wrap-up since it needs a real Claude Code session against the
running app — out of scope for unit/widget tests.
