# shutdown

  <Badge color="purple">Method</Badge>
</div>

> This is a method of the [**MCPToolRunner**](../classes/MCPToolRunner) class in the [**mcp**](../modules/mcp) module.

Signal the thread to shut down.

Queues a sentinel that the request loop consumes to exit cleanly. This
only takes effect once initialization has completed and the loop is
running; use :meth:`stop` for a best-effort teardown when init never
finished (e.g. a timed-out handshake) so the daemon thread and its
stdio child do not leak across construction retries (issue #4375).

## Signature

```python theme={"theme":{"light":"vitesse-light","dark":"vitesse-dark"}}
def shutdown() -> Any
```

### Returns
