Receive browser debug sessions from the NetTrace browser extension and expose failures to AI agents via native VS Code Language Model tools.
Features
Zero-config receiver -- automatically starts a localhost server that your browser extension connects to
AI-native tools -- 7 language model tools registered natively so Copilot, Cursor, and other AI agents can query captured sessions, failures, and reproduction context
Failure clusters -- correlates user actions (clicks, form submits) with failed HTTP requests and console errors
Automatic redaction -- passwords, tokens, API keys, cookies, and other sensitive data are redacted before storage
Session tree view -- browse captured sessions and failures in the activity bar sidebar
MCP fallback -- registers as an MCP server definition provider for IDE clients that need MCP
Getting Started
Install the NetTrace browser extension for Chrome or Firefox
Install this IDE Companion from the VS Code / Cursor marketplace
Open the command palette and run NetTrace: Connect Account — paste your device token from nettrace.ai/dashboard
The receiver starts automatically and your browser extension connects using the same account — no manual pairing needed
Browse your web app — failures appear in the NetTrace sidebar
Ask your AI agent: "What went wrong in NetTrace?"
