Analytics & Privacy

Arcade MCP Server collects anonymous usage data to help us improve the service and debug issues. We track "MCP server start" events to understand server usage patterns and reliability.

What We Track

When the server starts, we collect the following information:

• Server configuration: transport type (http or stdio), host, port
• Server metadata: tool count, server version
• Runtime environment: Python version, OS type and release
• Timing: device timestamp
• Errors: error messages (if startup fails)

Privacy

• For anonymous users: Events are tracked with an anonymous ID and no user profile is created
• For authenticated users: Events are linked to your account to help us provide better support
• No sensitive data (credentials, tool inputs/outputs, or personal information) is ever collected

Opt Out

To disable usage tracking, set the environment variable ARCADE_USAGE_TRACKING to 0.
