tasks

The io.modelcontextprotocol/tasks extension: long-running work registered with @task, polled via tasks/get, updated mid-flight, and cancelled with tasks/cancel. The story will show a task that outlives the request that started it.

Status: not yet implemented. The extension types exist but the extensions capability map is not yet surfaced on MCPServer, and the runtime trails the release. The TypeScript SDK deliberately removed its tasks example pending the same work.
