BrowserTools MCP

BrowserTools MCP

BrowserTools MCP is a powerful tool that enables AI-powered applications to monitor and interact with browser data through a Chrome extension. It works with MCP-compatible clients like Cursor, allowing users to capture console logs, network activity, screenshots, and analyze web pages for accessibility, performance, SEO, and best practices. The system consists of a Chrome extension, a Node.js server, and an MCP server, ensuring all data stays local and secure. It streamlines browser audits and debugging directly within supported IDEs, enhancing developer productivity and web application quality.
