# AX MCP Endpoints

> Regional endpoint URLs for the Arize AX MCP server, plus where OAuth sign-in happens in each region and which transport to configure.

## 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`.

## OAuth sign-in

The server is configured for OAuth sign-in in the US, EU, and Canada regions. Sign-in happens on the Arize app domain for your region:

| Region | Sign-in domain |
| - | - |
| Global | `app.arize.com` |
| EU (`eu-west-1a`) | `app.eu-west-1a.arize.com` |
| Canada (`ca-central-1a`) | `app.ca-central-1a.arize.com` |

Your client finds the right domain by reading `/.well-known/oauth-protected-resource` on the MCP endpoint, so you do not configure it yourself. See [authentication](/docs/api-clients/mcp/authentication.md) for details.

> [!NOTE]
>
> Keys are scoped to the account they were created in. Use a key with the endpoint for the region your account lives in.
