About BrowserTools MCP

A browser monitoring and interaction MCP server that enables AI tools to capture, analyze, and interact with browser activity.

BrowserTools MCP is an open-source Model Context Protocol server and Chrome extension that connects AI assistants with live browser data. Built by AgentDeskAI, it allows IDEs such as Cursor and other MCP-compatible tools to capture console logs, network activity, and accessibility insights directly from Chrome DevTools. With features like auto-paste into Cursor, Lighthouse-powered SEO and performance audits, and specialized debugging and auditing modes, BrowserTools MCP provides developers with a powerful environment for testing and improving web applications. It bridges browser runtime data with AI reasoning, enabling more context-aware automation, analysis, and debugging.
