      "type": "stdio",
      "command": "npx",
      "args": ["-y", "@railway/mcp-server"]
    }
  }
}

claude mcp add railway-mcp-server -- npx -y @railway/mcp-server

Example Usage

Creating a new project, deploying it, and generating a domain

Create a Next.js app in this directory and deploy it to Railway. Make sure to also assign it a domain. Since we're starting from scratch, there is no need to pull information about the deployment or build for now

Deploy a from a template (database, queue, etc.). Based on your prompt, the appropriate template will be selected and deployed. In case of multiple templates, the agent will pick the most appropriate one. Writing a detailed prompt will lead to a better selection. Check out all of the available templates.

Deploy a Postgres database

Deploy a single node Clickhouse database

Pulling environment variables

I would like to pull environment variables for my project and save them in a .env file

Creating a new environment and setting it as the current linked environment

I would like to create a new development environment called `development` where I can test my changes. This environment should duplicate production. Once the environment is created, I want to set it as my current linked environment

CLI Version Detection

The MCP server automatically detects your Railway CLI version to use the appropriate features.

Development

Prerequisites

• Node.js >= 20.0.0

• pnpm >= 10.14.0

1. Clone the repository

   git clone https://github.com/railwayapp/railway-mcp-server.git
   cd railway-mcp-server

2. Install dependencies

   pnpm install

3. Start the development server

   pnpm dev

   This command will generate a build under dist/ and automatically rebuild after making changes.

4. Configure your MCP client

   Add the following configuration to your MCP client (e.g., Cursor, VSCode) and replace /path/to/railway-mcp-server/dist/index.js with the actual path to your built server.

   Cursor: .cursor/mcp.json

   {
     "mcpServers": {
       "railway-mcp-server": {
         "command": "node",
         "args": ["/path/to/railway-mcp-server/dist/index.js"]
       }
     }
   }

   VSCode: .vscode/mcp.json

   {
     "servers": {
       "railway-mcp-server": {
         "type": "stdio",
         "command": "node",
         "args": ["/path/to/railway-mcp-server/dist/index.js"]
       }
     }
   }

   For Claude Code:

   claude mcp add railway-mcp-server node /path/to/railway-mcp-server/railway-mcp-server/dist/index.js
