   npm install
   

3. Configure environment variables

   cp .env.example .env
   # Edit .env with your Coolify instance details
   

4. Build the project

   npm run build
   

Configuration

Environment Variables

Create a .env file with the following variables:

# Required: Your Coolify instance URL
COOLIFY_BASE_URL=https://your-coolify-instance.com

# Required: API token from Coolify
COOLIFY_API_TOKEN=your-api-token-here

# Optional: Team ID for scoped access
COOLIFY_TEAM_ID=your-team-id

Getting Your API Token

1. Log into your Coolify dashboard
2. Go to Settings → Keys & Tokens → API Tokens
3. Click Create New Token
4. Choose permissions:
   • read-only: View data only
   • read:sensitive: View sensitive data
   • *: Full access (recommended for automation)
5. Copy the generated token to your .env file

Security Considerations

• API Tokens: Store API tokens securely using environment variables
• Network Access: Ensure your Coolify instance is accessible from where this MCP server runs
• Permissions: Use appropriate API token permissions based on your use case
• HTTPS: Always use HTTPS for production Coolify instances

Troubleshooting

Common Issues

1. Connection Failed

   • Verify COOLIFY_BASE_URL is correct and accessible
   • Check that API token has proper permissions
   • Ensure Coolify instance is running

2. Permission Denied
