Using Siren MCP with Cursor

Cursor uses the same configuration format as VS Code. Add this to your settings: 
{
  "mcp.servers": {
    "siren": {
      "command": "npx",
      "args": [
        "-y",
        "@trysiren/mcp",
        "--tools=all",
        "--api-key=YOUR_SIREN_API_KEY"
      ]
    }
  }
}

​
Configuration Options

  • Replace YOUR_SIREN_API_KEY with your actual Siren API key
  • Adjust the --tools flag to enable only the tools you need
  • The configuration is similar to VS Code but might have slight differences in how settings are applied

​
Verifying the Setup

  1. Restart Cursor after making these changes
  2. Open the command palette (Ctrl+Shift+P or Cmd+Shift+P)
  3. Look for MCP-related commands to verify the connection

​
Troubleshooting

  • Ensure Node.js and npm are installed if using the npx method
  • Check the Cursor logs for any error messages
  • Verify your API key has the necessary permissions
  • Make sure your network allows connections to the Siren API

​
Advanced Configuration

​
Keyboard Shortcuts

Add custom keyboard shortcuts for frequently used tools in keybindings.json: 
[
  {
    "command": "mcp.executeTool",
    "key": "ctrl+alt+s",
    "args": {
      "server": "Siren",
      "tool": "messaging.send"
    }
  }
]

​
Troubleshooting

  • Connection Issues:
    • Verify your API key and network connectivity
    • Check that the MCP server URL is correct
  • Tool Not Found:
    • Ensure the tool names in your config match exactly
    • Check that the tools are included in your API key’s permissions
  • Permission Errors:
    • Verify your API key has the necessary permissions
    • Check the Siren dashboard for any rate limits or restrictions

​
Security Best Practices

  • Never commit API keys to version control
  • Use environment variables or secure credential storage
  • Regularly rotate your API keys
  • Follow the principle of least privilege when assigning permissions
