- Add client.onclose handler to unregister tools when the MCP server
disconnects (crash or intentional close)
- Replace bare `let disposers` with a shared mutable state object so the
effect disposer and notification handler always reference the current
generation
- Serialize tools/list_changed resyncs with latest-wins coalescing
(syncing + pendingResync flags) to prevent concurrent races
Connects to an external MCP server and registers its tools on
ctx.tools. Supports stdio (child process) and Streamable HTTP
transports. Credential-shaped env vars are scrubbed before forwarding
to child processes.
- Plugin lifecycle: connect, sync tools, re-sync on ToolListChanged,
dispose unregisters and closes
- Full JSDoc on all exports (@param/@returns on functions)
- 100% per-file coverage (apply lifecycle, args coercion, env scrubbing)
- Config catalog regenerated
