# AlloyDB MCP Usage

AlloyDB supports a remote Model Context Protocol (MCP) server, allowing AI
applications to interact with AlloyDB resources.

## Endpoint

The AlloyDB MCP server endpoint is regional:
`https://alloydb.REGION.rep.googleapis.com/mcp`

Replace `REGION` with the regional location of the endpoint (e.g.,
`us-central1`).

## Setup and Authentication

1. Enable the AlloyDB API in your project.
2. Grant the `roles/mcp.toolUser` role to the principal making the tool calls.
3. Configure your MCP host to point to the regional endpoint.

For more details, see the [Use the AlloyDB remote MCP
server](https://cloud.google.com/alloydb/docs/ai/use-alloydb-mcp) guide.
