Yavio: Open-Source Product Analytics SDK for MCP Apps

Yavio is an open-source product analytics SDK designed specifically for MCP and MCP Apps. The project was built using Claude Code as the primary development tool for the majority of the codebase, including the SDK, ingestion API, and dashboard.

What Yavio Does

Yavio wraps your MCP App with one function call and automatically captures every tool call, error, and resource read. This provides developers with visibility into how their tools are being used, where users drop off, and what drives revenue.

How It Works

Integration requires just one function call:

const server = withYavio(new McpServer({ name: "my-app", version: "1.0.0" }));

Features

• Automatic capture of tool calls, errors, and resource reads
• Dashboard with per-tool breakdowns
• Funnel analysis
• Retention tracking
• Error tracking

Technical Details

• Current version: v0.1.0
• License: MIT
• Free to self-host with Docker
• Cloud version coming soon

Development Approach

The developers used Claude Code for the majority of the codebase, describing it as their "best friend" during development. The project is being built in the open, with the team actively seeking feedback on what insights developers want about their MCP Apps.

This type of analytics tool is particularly useful for developers building MCP Apps who need visibility into how their tools are being used in production environments.
