Chrome MCP Server - A Chrome extension-based MCP server

What is Chrome MCP Server?

Chrome MCP Server is a Model Context Protocol (MCP) server based on the Chrome extension that exposes Chrome browser functionality to AI assistants like Claude. It allows AI to directly control a user's daily Chrome browser, leveraging existing user habits, configurations, and login status to achieve complex browser automation, content analysis, and semantic search. Chrome MCP Server supports streaming HTTP connections, cross-tab context, semantic search, and intelligent content analysis, and provides over 20 tools such as screenshotting, network monitoring, and bookmark management. Chrome MCP Server runs entirely locally, ensuring user privacy, and is optimized for faster vector operations based on WebAssembly SIMD.

Main functions of Chrome MCP Server

• Browser automationIt allows direct control of the Chrome browser based on an AI assistant, enabling various automated operations such as opening web pages, closing tabs, and navigation control.
• Content analysis and semantic searchIt uses AI technology to analyze web page content and perform semantic search, helping users quickly find the information they need.
• Intelligent interactive operationAI interacts with web pages, such as clicking buttons, filling out forms, and simulating keyboard input.
• Data ManagementIt supports the management and manipulation of browser history, bookmarks, and other data.
• Screenshots and VisualsProvides advanced screenshot functionality, supporting screenshots of web page elements, the entire page, or custom areas.
• Network monitoringCapture and analyze network requests to help users understand web page activity.
• User privacy protectionIt runs entirely locally, ensuring that user data is not leaked.

Technical Principles of Chrome MCP Server

• Chrome extensionBased on the Chrome extension architecture, it runs directly in the user's Chrome browser, allowing access to and operation of various browser functions.
• Model Context Protocol (MCP)It communicates with the AI assistant based on the MCP protocol, transmitting browser operations and data to the AI and receiving instructions from the AI.
• Streaming HTTP connectionsIt supports streaming HTTP connections, allowing AI assistants to interact with the browser in real time, thus improving response speed.
• Local Vector DatabaseIt has a built-in vector database for storing and retrieving semantic information from web page content, supporting intelligent search and content analysis.
• WebAssembly SIMD Optimization: Optimize AI operations using WebAssembly SIMD technology to improve the speed of vector computation and enhance performance.
• Native API accessUsing Chrome's native API, it provides full access to browser functionality, offering greater flexibility and performance compared to traditional automation tools like Playwright.
