Why

Railway has an official MCP server but it wraps the CLI and only works locally (stdio transport). This server hits the Railway GraphQL API directly over HTTP, so it can be deployed as a remote service and connected to claude.ai as a connector.

Setup

1. Get a Railway API Token

Go to railway.com/account/tokens and create an account-level token.

2. Deploy to Railway

• Create a new Railway project

• Connect this GitHub repo

• Set environment variables:

  • RAILWAY_API_TOKEN = your token

  • PORT = 8000

  • MCP_TRANSPORT = streamable-http

• Generate a public domain

3. Connect to claude.ai

Add the MCP connector URL: https://{your-domain}/mcp

Local Development
