BrowserTools

About

BrowserTools provides a suite of tools for AI-powered applications to deeply integrate with and understand web browser activity. By leveraging a Chrome extension and a local Node.js server communicating via the Model Context Protocol (MCP), AI clients like Cursor can access real-time browser console logs, network traffic, DOM elements, and screenshots. Additionally, it offers powerful auditing capabilities, including accessibility, performance, SEO, and best practices checks, allowing for comprehensive analysis and improvement of web applications directly from within your IDE. All data is stored locally to ensure privacy and security.
