# AX MCP Endpoints

> Regional endpoints for the Arize AX MCP server.

## Endpoints

| Region                   | URL                                       |
| ------------------------ | ----------------------------------------- |
| Global                   | `https://api.arize.com/mcp`               |
| EU (`eu-west-1a`)        | `https://api.eu-west-1a.arize.com/mcp`    |
| Canada (`ca-central-1a`) | `https://api.ca-central-1a.arize.com/mcp` |

Use the global endpoint unless data residency requires otherwise. The transport is Streamable HTTP, so configure your client with type `http` rather than `stdio` or `sse`.

<Note>
  Keys are scoped to the account they were created in. A key from your EU account will not authenticate against the global endpoint, and the failure looks like a permission error rather than a bad key.
