Connectors

Manages connector definitions and execution configurations used by Data Connections.

📄️ List Connector Usages

Covers MCP tools (by ``options.mcp.connector_id`` or collection-scoped ``ref``), data syncs (``source``/``target.connector_id``) and semantic tables (``connector`` name, resolved the way the query runtime resolves it). The MCP tool test is the one the delete guard uses, so the listing and the 409 agree. Pipeline and code ``@use_connector`` references live in script text and are not scanned — ``covers`` says so, and an empty listing is not proof the connector is unused. Requires read permission on the connector; the referencing resources' permissions are not checked (usage visibility intent, mirroring ``GET /datasets/{id}/usages`` and ``GET /codes/{id}/usages``). Builtins go through the same ``read`` check as ``GET /connectors/{id}``.
