BrowserTools MCP: Browser Debugging and Interaction Tool for Empowering AI Editors

🧠 What is BrowserTools MCP?

BrowserTools MCP is an open-source browser monitoring and interaction tool designed to enhance AI editors (such as Cursor, Cline, Zed, etc.) with improved browser awareness and interaction capabilities using Anthropic’s Model Context Protocol (MCP). It captures browser console logs, network requests, DOM elements, screenshots, and more via a Chrome extension and communicates with a local Node.js server using MCP clients for real-time browser debugging and analysis.

⚙️ Key Features and Advantages

Browser Log Capture: Real-time monitoring of browser console outputs, network requests (XHR), DOM elements, and more to help developers quickly locate issues.
Screenshot Functionality: Captures screenshots of the current page via WebSocket communication with a Chrome extension, supporting automatic pasting into editors like Cursor.
Element Selection and Analysis: Allows users to select DOM elements on the current page and retrieve HTML structure, styles, and screenshots, aiding UI debugging and analysis.
Browser State Monitoring: Provides comprehensive debugging views by monitoring browser states including console logs, network requests, and DOM elements in real time.
Webpage Auditing: Integrates Lighthouse to perform accessibility, performance, SEO, and best practice audits, helping developers optimize webpage quality.
Privacy Protection: All logs and data are stored locally on the user’s machine and are never sent to any third-party services or APIs, ensuring user privacy and security.

🧬 Technical Principles

BrowserTools MCP is built on three core components:

Chrome Extension: Captures browser console logs, network activity, DOM elements, and screenshots, then communicates with the Node.js server via WebSocket.
Node.js Server: Acts as an intermediary server, receiving logs and element data from the Chrome extension, processing requests from the MCP server, and returning the results to the MCP server.
MCP Server: Implements the Model Context Protocol (MCP), providing standardized tools for AI clients to interact with the browser.

This architecture enables seamless communication between the browser and AI editors, providing powerful debugging and analysis features.
