Catchmetrics MCP: real-user web performance data in your AI app

Catchmetrics is a real-user monitoring platform for web performance, and its MCP server brings that data, including Core Web Vitals and third-party script monitoring, into your AI app. ContextGate connects it to Claude, ChatGPT and Cursor, so you can ask why a page got slower from the editor where you'll fix it, with each question kept in Activity.
