π Turn your Chrome browser into your intelligent assistant - Let AI take control of your browser, transforming it into a powerful AI-controlled automation tool.
π Documentation: English | δΈζ
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.
- π Chatbot/Model Agnostic: Let any LLM or chatbot client or agent you prefer automate your browser
- βοΈ Use Your Original Browser: Seamlessly integrate with your existing browser environment (your configurations, login states, etc.)
- π» Fully Local: Pure local MCP server ensuring user privacy
- π Streamable HTTP: Streamable HTTP connection method
- π Cross-Tab: Cross-tab context
- π§ Semantic Search: Built-in vector database for intelligent browser tab content discovery
- π Smart Content Analysis: AI-powered text extraction and similarity matching
- π 20+ Tools: Support for screenshots, network monitoring, interactive operations, bookmark management, browsing history, and 20+ other tools
- π SIMD-Accelerated AI: Custom WebAssembly SIMD optimization for 4-8x faster vector operations
