Railway MCP Server

Railway MCP MCP server is a locally run integration for AI assistants that speak the Model Context Protocol. Model Context Protocol server for Railway.app - Enables AI agents to manage Railway infrastructure through natural language.

What you get

• ✅ Authentication with Railway API tokens
• ✅ Project management (list, info, delete)
• ✅ Deployment management (list, restart)
• ✅ Service management (create from GitHub repo or Docker image, list)
• ✅ Variable management (list, create/update, delete)
• ✅ Service Network management

Setting it up

Installation goes through your MCP client rather than a global install: point it at @smithery/cli on npm and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.

What the assistant can call

Once Railway MCP is connected, these are the calls the assistant has available:

• Prerequisites — The Prerequisites tool exposed by this server
• Authentication — The Authentication tool exposed by this server
• Projects — The Projects tool exposed by this server
• Services — The Services tool exposed by this server
• Deployments — The Deployments tool exposed by this server
• Variables — The Variables tool exposed by this server
• Databases — The Databases tool exposed by this server

Configuration and credentials

You will need one environment variable: RAILWAY_API_TOKEN. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.

• Node.js 18+ (for built-in fetch API support) - An active Railway account - A Railway API token (create one at https://railway.app/account/tokens)

Before you rely on it

• It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
• Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
• MCP clients confirm each tool call by default. Leave that on until you have watched what the railway mcp mcp server does with a few real requests.

Choosing this one

This sits in the cloud and infrastructure group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Railway MCP's toolset — Prerequisites, Authentication, Projects and 4 more — is a fair guide to whether it matches your workflow. It is maintained by jason-tan-swe; worth a glance at recent repository activity before you build anything load-bearing on it.
