# Custom MCP

> Handwritten MCP session, authentication, operations, Cloud, and alert tools.

Custom MCP tools are registered directly by the MCP server rather than derived
from a service schema.

| Category                          | Authentication behavior                                                                                                                             |
| --------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------- |
| Session, Workspace, and discovery | Configure local MCP session state and do not require an existing bearer token.                                                                      |
| Authentication                    | Establish, inspect, or clear the bearer token stored for the MCP session.                                                                           |
| Health                            | Forward the session token to Admin APIs; downstream Admin authorization controls access.                                                            |
| Cloud and alerts                  | Exist only when a Google Cloud runner is configured and use its server-side credentials. They do not currently add a separate per-tool bearer gate. |

<Warning>
  `pipeline_status` is callable, but its relationship to the current Provider
  Pool model is unverified. Treat the name as a compatibility or legacy signal
  until its implementation and callers are mapped.
