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:
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_*).
