Railway Public GraphQL API

Create a token in Railway's dashboard. For account or workspace tokens, open Tokens in account settings; choose No workspace for an account token or select a workspace for a workspace token. For a project token, create it from the project's tokens page in project settings as described in Public API. Use account/workspace tokens as Bearer tokens; project tokens are sent in the Project-Access-Token header for the GraphQL API, and the CLI also supports token-based auth via RAILWAY_TOKEN or RAILWAY_API_TOKEN.

Point your MCP client at the server URL and approve access in the browser. The server supports OAuth Dynamic Client Registration (RFC 7591), so the client registers itself automatically — no developer-portal app, client_id, or client_secret to create.
