# `fastmcp.cli.tasks`

FastMCP tasks CLI for Docket task management.

## Functions

### `check_distributed_backend` <sup><a href="https://github.com/jlowin/fastmcp/blob/main/src/fastmcp/cli/tasks.py#L22" target="_blank"><Icon icon="github" style="width: 14px; height: 14px;" /></a></sup>

```python  theme={"theme":{"light":"snazzy-light","dark":"dark-plus"}}
check_distributed_backend() -> None
```

Check if Docket is configured with a distributed backend.

The CLI worker runs as a separate process, so it needs Redis/Valkey
to coordinate with the main server process.

**Raises:**

* `SystemExit`: If using memory:// URL

### `worker` <sup><a href="https://github.com/jlowin/fastmcp/blob/main/src/fastmcp/cli/tasks.py#L61" target="_blank"><Icon icon="github" style="width: 14px; height: 14px;" /></a></sup>

```python  theme={"theme":{"light":"snazzy-light","dark":"dark-plus"}}
worker(server_spec: Annotated[str | None, cyclopts.Parameter(help='Python file to run, optionally with :object suffix, or None to auto-detect fastmcp.json')] = None) -> None
```

Start an additional worker to process background tasks.

Connects to your Docket backend and processes tasks in parallel with
any other running workers. Configure via environment variables
(FASTMCP\_DOCKET\_\*).
