MCP Client Compatibility

Client	Status	Testing Level
Claude for Desktop	✅ Fully Tested	Production Ready
Cursor	✅ Verified	Enterprise Features Tested
Cline	🧪 Compatible	Basic Testing
Windsurf	🧪 Compatible	Basic Testing
Other MCP Clients	🧪 Universal MCP	Should Work

Installing via Smithery

To install railway-mcp automatically, we recommend using Smithery

Claude Desktop

npx -y @smithery/cli install @jason-tan-swe/railway-mcp --client claude

Cursor

npx -y @smithery/cli@latest run @jason-tan-swe/railway-mcp --config "{\"railwayApiToken\":\"token\"}"

Manual Installation For Cursor

• Head to your cursor settings and find the MCP section

• Click 'Add new MCP server'

• Name it however, you like, we recommend railway-mcp for better clarity

• Paste this command into the 'Command' section, where <RAILWAY_API_TOKEN> is your accounts Railway token:

npx -y railway-mcp <RAILWAY_API_TOKEN>

Manual Installation For Claude

• Create or edit your Claude for Desktop config file:

  • macOS: ~/Library/Application\ Support/Claude/claude_desktop_config.json
  • Windows: %APPDATA%\Claude\claude_desktop_config.json

• Add the railway-mcp server to your configuration with your API token:

   "railway": {
      "command": "npx",
      "args": ["-y", "railway-mcp"],
      "env": {
         "RAILWAY_API_TOKEN": "your-railway-api-token-here"
      }
   }

When you have multiple MCP servers, your config file might look like this:

{
  "mcpServers": {
    // ... All of your existing MCP servers ...

    // Add the railway-mcp server to your configuration with your API token
    "railway": {
      "command": "npx",
      "args": ["-y", "railway-mcp"],
      "env": {
        "RAILWAY_API_TOKEN": "your-railway-api-token-here"
      }
    }
  }
}

• Restart Claude for Desktop

• You can now start using Railway tools directly in Claude. For example:

Please list all my Railway projects

• Alternatively, if you don't want to add your token to the configuration file, you can configure it within Claude using:

Please configure the Railway API with my token: {YOUR_API_TOKEN_HERE}

Recommendations and Other Information

This server best combines with MCP-clients that have access to terminal or with Git (Cursor, Windsurf). Using this MCP with others is recommended as railway-mcp orchestrates containers and streamlines your deployment process seamlessly.

Recommended MCP servers to combine with

• Git || Official Link
• GitHub || Official || Smithery

For Claude

• Out of the box, Claude does not have terminal access, so it cannot trigger deployments as it will not be able to get the latest commit.
• Spinning up different services and monitoring them are the best use case with Claude.

For Cursor

• Use with GitHub MCP or have the repository already setup on GitHub and cloned locally on your machine to leverage full integration with railway-mcp.
• When Cursor makes a change, it may forget to push it's changes to GitHub causing it to try and deploy a commit that Railway cannot pull.
  • SOLUTION: Always ask or include somewhere in your prompt: Have you pushed our changes to GitHub yet?

Security Considerations

• Railway API tokens provide full access to your account. Keep them secure.
• When using the environment variable method, your token is stored in the Claude Desktop configuration file.
• Sensitive variable values are automatically masked when displayed.
• All API calls use HTTPS for secure communication.
• The server's memory-only token storage means your token is never written to disk outside of the configuration file.

Tool Filtering

The Railway MCP server provides intelligent tool filtering to manage the complexity of 146+ available tools. This feature allows you to expose only relevant subsets of tools based on your use case and complexity level.

Why Tool Filtering?

• Reduces Cognitive Load: Focus on essential tools for your current task
• Improves LLM Performance: Smaller tool sets lead to better tool selection
• Context Efficiency: Saves valuable context tokens
• Role-Based Access: Different tool sets for different user types

Configuration

By default, ALL tools are enabled (no filtering). Tool filtering only activates when you explicitly set the RAILWAY_TOOLS_FILTER environment variable.

Getting All Tools (Default Behavior)

# Method 1: No environment variable (default - all 146+ tools)
npx railway-mcp

# Method 2: Set to "pro" category (all 146+ tools)
export RAILWAY_TOOLS_FILTER="pro"

# Method 3: Set to empty string (all 146+ tools)
export RAILWAY_TOOLS_FILTER=""

Filtering Tools

Set the RAILWAY_TOOLS_FILTER environment variable to filter tools:

# For complete beginners
export RAILWAY_TOOLS_FILTER="extra-simple"
npx railway-mcp

# Basic users - essential operations only (42 tools)
export RAILWAY_TOOLS_FILTER="simple"

# Developers - includes creation/management (65 tools) 
export RAILWAY_TOOLS_FILTER="intermediate"

# Multiple categories
export RAILWAY_TOOLS_FILTER="simple,deployment"

# Specific tools only
export RAILWAY_TOOLS_FILTER="project_list,service_create_from_repo,deployment_info"

# Mixed approach
export RAILWAY_TOOLS_FILTER="simple,backup-restore,security-audit-logs"

Available Categories

Complexity Levels

• extra-simple (9 tools): Absolute essentials for basic service management
• simple (42 tools): Information, listing, and status operations
• intermediate (65 tools): Includes simple + creation, deletion, basic management
• pro (146+ tools): All tools including advanced workflows and enterprise features

Use Case Categories

• core (25 tools): Essential project, service, and deployment management
• deployment (18 tools): Service creation and deployment operations
• data (20 tools): Database, volume, backup, and variable management
• monitoring (22 tools): Logs, metrics, alerts, and observability
• enterprise (35 tools): Advanced networking, security, and compliance
• team (12 tools): Team management, usage, and billing
• integration (15 tools): Webhooks, templates, and external integrations
• utility (8 tools): Configuration and helper tools

Filter Management Tools

The server includes built-in tools to help manage filtering:

• tool_filter_current: Show active filter configuration
• tool_filter_validate: Test filter strings before applying
• tool_filter_examples: Get example configurations for different use cases
• tool_filter_categories: List all available categories with descriptions

Configuration Examples

Claude Desktop Configuration:

{
  "mcpServers": {
    "railway": {
      "command": "npx",
      "args": ["-y", "railway-mcp"],
      "env": {
        "RAILWAY_API_TOKEN": "your-token-here"
        // No RAILWAY_TOOLS_FILTER = all tools (default)
        // "RAILWAY_TOOLS_FILTER": "intermediate,monitoring"  // Optional filtering
      }
    }
  }
}

Command Line Usage:

# Default: All tools (no filtering)
npx railway-mcp

# Test different filter configurations
RAILWAY_TOOLS_FILTER="extra-simple" npx railway-mcp
RAILWAY_TOOLS_FILTER="simple" npx railway-mcp
RAILWAY_TOOLS_FILTER="deployment,data" npx railway-mcp

Best Practices

• Default is All Tools: No configuration needed for full functionality
• Start Simple When Filtering: Begin with simple category and add more as needed
• Use Case Focused: Combine complexity with use case (e.g., intermediate,deployment)
• Validate First: Use tool_filter_validate to test configurations
• Check Current Status: Use tool_filter_current to verify active settings

Troubleshooting

If you encounter issues:

• Token Authentication Issues

  • Ensure your API token is valid and has the necessary permissions
  • If using the environment variable method, check that the token is correctly formatted in the config file
  • Try using the configure tool directly in Claude if the environment token isn't working

• Server Connection Issues

  • Check that you've installed the latest version of the server
  • Verify that Node.js version 18 or higher is installed
  • Restart Claude for Desktop after making changes to the configuration

• API Errors

  • Verify that you're using correct project, environment, and service IDs
  • Check Railway's status page for any service disruptions
  • Railway API has rate limits - avoid making too many requests in a short period

💻 MCP Client Examples

🖥️ Claude Desktop Usage

After installing via Smithery or manual configuration, you can use natural language to manage Railway infrastructure:

# Project Management
"List all my Railway projects"
"Create a new project called 'my-startup-app'"
"Show me details for project abc123"

# Full-Stack Deployment
"Deploy a Next.js app from my GitHub repo 'username/my-app'"
"Add a PostgreSQL database to this project"
"Set the DATABASE_URL environment variable for my service"
"Create a custom domain for my app"

# Monitoring & Maintenance
"Show me the logs for my service deployment"
"Create a backup of my database"
"Set up daily automated backups"
"Generate a security audit report"

Claude Desktop excels at orchestrating complex workflows and providing detailed explanations of Railway operations.

⚡ Claude Code (CLI) Usage

Claude Code provides powerful terminal integration for development workflows:

# In your terminal with Claude Code
claude "List my Railway projects and deploy the latest version of my app"

# Development workflow
claude "Create a staging environment, deploy my current branch, and run tests"

# Infrastructure management
claude "Scale up my database, check performance metrics, and optimize if needed"

# Emergency response
claude "My app is down - check logs, identify issues, and redeploy if necessary"

Claude Code is ideal for development workflows, CI/CD automation, and rapid infrastructure management during development.

🎯 Cursor IDE Integration

Cursor provides seamless code-to-deployment workflows:

// While coding in Cursor, use natural language:

"Push my changes to GitHub and deploy to Railway staging environment"

"This API needs a Redis cache - add Redis to Railway and update my environment variables"

"Create a production environment with the same services as staging"

"Set up monitoring alerts for this new API endpoint"

// Cursor + Railway MCP workflow:
// 1. Code changes in Cursor
// 2. Cursor commits and pushes to GitHub  
// 3. Railway MCP deploys automatically
// 4. Monitor and manage through natural language

Cursor excels at connecting your development environment directly to Railway infrastructure with Git integration.
