What is Chrome MCP Server？
Chrome MCP Server is a Model Context Protocol (MCP) server based on a Chrome extension that exposes Chrome browser functionalities to AI assistants such as Claude. It enables AI to directly control the user’s everyday Chrome browser by leveraging existing habits, configurations, and login states, enabling advanced browser automation, content analysis, and semantic search. Chrome MCP Server supports streaming HTTP connections, cross-tab context sharing, semantic search, and intelligent content analysis. It offers over 20 built-in tools, including screenshot capture, network monitoring, and bookmark management. The server runs entirely locally to ensure user privacy and utilizes WebAssembly SIMD optimizations for faster vector operations.
