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

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_*).
