About
Chrome MCP Server is a browser automation system that turns your Chrome browser into an AI-controlled tool accessible to LLM assistants. Unlike traditional automation frameworks that require separate browser instances, this Chrome extension-based solution works directly with your existing browser—preserving your login states, preferences, and browsing habits. Key features of Chrome MCP Server: - Native Chrome extension that integrates directly with your daily browser environment - 20+ automation tools including screenshots, network monitoring, bookmark management, and browsing history access - Built-in vector database with semantic search capabilities for finding content across open tabs - AI-powered text extraction with similarity matching and WebAssembly SIMD acceleration (4-8x performance boost) - Streamable HTTP support and cross-tab context awareness - Fully local processing ensuring privacy and data security - Compatible with any MCP-compliant LLM client including Claude, Codex, and other chatbots

🎯 What is Chrome MCP Server?
Chrome MCP Server is a Chrome extension-based Model Context Protocol (MCP) server that exposes your Chrome browser functionality to AI assistants like Claude, enabling complex browser automation, content analysis, and semantic search. Unlike traditional browser automation tools (like Playwright), Chrome MCP Server directly uses your daily Chrome browser, leveraging existing user habits, configurations, and login states, allowing various large models or chatbots to take control of your browser and truly become your everyday assistant.
