Usage Data Collection with Telemetry

The PWA Kit MCP server collects minimal, anonymous usage data to improve reliability and the developer experience.

What's Included 

  • Server lifecycle events: started, stopped, errors (SERVER_STATUS)
  • Tool usage: tool name, run time, success/error (TOOL_CALLED)

What's Not Included 

The MCP server doesn’t collect any source code, file contents, prompts, or secrets.

How to Opt Out of Telemetry 

To disable telemetry, add --no-telemetry to your args in mcp.json.

Telemetry for the PWA Kit MCP server is in developer preview and subject to change. Event names, payloads, and destinations may change without notice; the feature may be modified or removed.
