Why we included this project

BrowserTools MCP gives AI coding assistants a direct window into the browser. A Chrome extension plus a local server feed console logs, network traffic, page errors, and screenshots straight into Cursor or any MCP-compatible IDE, so the agent can debug a broken frontend without you copying and pasting error text back and forth. It also bundles Lighthouse-based audits the agent can run against the open page without leaving the editor. One honest caveat: the maintainers marked the repo as no longer active, so treat it as a reference implementation and check for a maintained successor before building a workflow around it. The architecture is a clean example of giving coding agents eyes on the live page.
