How do I use gn-tracing-mcp?

1. Click on "Deploy Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@gn-tracing-mcp read this replay link and show console errors with source-mapped stacks" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

GN Tracing OSS

Open-source companion to GN Tracing — a browser extension that records a tab (video, console, network, WebSocket) into a shareable replay.

This repo carries the parts of the project that are useful on their own:

Path	What it is
`mcp/`	`gn-tracing-mcp` — MCP server that lets a coding agent read a replay link or a `gn-tracing-*.zip` package: console errors with source-mapped stacks, failed requests, and the user timeline.
`packages/replay-core/`	`@gn-tracing/replay-core` — runtime-agnostic parser for recording packages (zip reader, artifact models, agent summary, query, report).
`src/shared/`	Shared helpers the replay-core tests compare against, synced from the main repo.

Quick start

cd mcp
npm ci
npm run build   # → dist/gn-tracing-mcp.mjs

Wire node dist/gn-tracing-mcp.mjs into your MCP client — details in mcp/README.md.
