Yavio Documentation
Product analytics for MCP Apps and ChatGPT Apps
Yavio gives developers complete visibility into how users interact with their MCP-powered apps — from server-side tool calls to widget conversions — with zero-config instrumentation, combined funnels, and real-time analytics.
What is Yavio?
Yavio is an open-source product analytics platform purpose-built for the MCP (Model Context Protocol) ecosystem. It tracks how AI platforms like ChatGPT, Claude, and Cursor invoke your tools, how users interact with your widgets, and where they convert — all stitched together with a single trace ID.

- User identification —
