- src/mcp_prefect/deployment.py:249-306 (handler)The main handler function for the MCP tool 'set_deployment_schedule'. It is decorated with @mcp.tool for registration and implements the logic to set a Prefect deployment's schedule using either cron or interval-based scheduling via the Prefect client.
