Implementation Reference
- src/airflow/connection.py:11-20 (registration)Registers the update_connection tool (along with other connection tools) in the get_all_functions list used for MCP tool registration.
def get_all_functions() -> list[tuple[Callable, str, str, bool]]: """Return list of (function, name, description, is_read_only) tuples for registration.""" return [ (list_connections, "list_connections", "List all connections", True), (create_connection, "create_connection", "Create a connection", False), (get_connection, "get_connection", "Get a connection by ID", True), (update_connection, "update_connection", "Update a connection by ID", False), (delete_connection, "delete_connection", "Delete a connection by ID", False), (test_connection, "test_connection", "Test a connection", True), ] - src/airflow/connection.py:77-106 (handler)The main handler function for the update_connection tool. It constructs an update request from the provided parameters and calls the Airflow ConnectionApi to patch the connection.
