# `fastmcp.cli.tasks`
FastMCP tasks CLI for Docket task management.
## Functions
### `check_distributed_backend`
```python
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`
```python
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_*).
