MCP Planned

Progress and cancellation

Report progress and cancel active MCP executions.

> **Planned. Not available today.** MCP execution currently returns a completed result or a pending job ID. It does not expose progress notifications or job cancellation.

## Intended outcome

Clients should eventually be able to observe bounded progress and request cancellation without changing REST/MCP credit semantics or losing idempotency.

Cancellation must define whether work is merely no longer awaited or is actually stopped in the worker plane. Documentation must not use those meanings interchangeably.
