Railway MCP Server

A Model Context Protocol (MCP) server for interacting with your Railway account. This is a local MCP server provides a set of opinionated workflows and tools for managing Railway resources.

[!IMPORTANT] The MCP server doesn't include destructive actions by design, that said, you should still keep an eye on which tools and commands are being executed.

Prerequisites

The Railway CLI is required for this server to function.

Installation

You can install the MCP server by running the following command:

npx add-mcp @railway/mcp-server --name railway

Cursor

You can add the Railway MCP Server to Cursor by clicking the button below.

Alternatively, you can add the following configuration to .cursor/mcp.json

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

VS Code:

Add the following configuration to .vscode/mcp.json

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

Claude Code:

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.

Available MCP Tools

The Railway MCP Server provides the following tools for managing your Railway infrastructure:

• check-railway-status - Checks that the Railway CLI is installed and that the user is logged in
• Project Management
  • list-projects - List all Railway projects
  • create-project-and-link - Create a new project and link it to the current directory
• Service Management
  • list-services - List all services in a project
  • link-service - Link a service to the current directory
  • deploy - Deploy a service
  • deploy-template - Deploy a template from the Railway Template Library
• Environment Management
  • create-environment - Create a new environment
  • link-environment - Link an environment to the current directory
• Configuration & Variables
  • list-variables - List environment variables
  • set-variables - Set environment variables
  • generate-domain - Generate a railway.app domain for a project
• Monitoring & Logs
  • get-logs - Retrieve build or deployment logs for a service
    • Railway CLI v4.9.0+: Supports lines parameter to limit output and filter parameter for searching logs
    • Older CLI versions: Will stream logs without filtering capabilities

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
