Chrome MCP Server 🚀

Stars License: MIT TypeScript Chrome Extension Release

🌟 Turn your Chrome browser into your intelligent assistant - Let AI take control of your browser, transforming it into a powerful AI-controlled automation tool.

📖 Documentation: English | 中文

The project is still in its early stages and is under intensive development. More features, stability improvements, and other enhancements will follow.


🎯 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.

🚀 Quick Start

Prerequisites

Installation Steps

  1. Download the latest Chrome extension from GitHub

Download link: https://github.com/hangwin/mcp-chrome/releases

  1. Install mcp-chrome-bridge globally

npm

npm install -g mcp-chrome-bridge

pnpm

# Method 1: Enable scripts globally (recommended)
pnpm config set enable-pre-post-scripts true
pnpm install -g mcp-chrome-bridge

# Method 2: Manual registration (if postinstall doesn't run)
pnpm install -g mcp-chrome-bridge
mcp-chrome-bridge register

Note: pnpm v7+ disables postinstall scripts by default for security. The enable-pre-post-scripts setting controls whether pre/post install scripts run. If automatic registration fails, use the manual registration command above.

  1. Load Chrome Extension
    • Open Chrome and go to chrome://extensions/
    • Enable "Developer mode"
    • Click "Load unpacked" and select your/dowloaded/extension/folder
    • Click the extension icon to open the plugin, then click connect to see the MCP configurationScreenshot 2025-06-09 15 52 06

Usage with MCP Protocol Clients

Add the following configuration to your MCP client configuration (using CherryStudio as an example):

Streamable HTTP connection method is recommended

{
  "mcpServers": {
    "chrome-mcp-server": {
      "type": "streamableHttp",
      "url": "http://127.0.0.1:12306/mcp"
    }
  }
}

Using STDIO Connection (Alternative)

If your client only supports stdio connection method, please use the following approach:

  1. First, check the installation location of the npm package you just installed
# npm check method
npm list -g mcp-chrome-bridge
# pnpm check method
pnpm list -g mcp-chrome-bridge

Assuming the command above outputs the path: /Users/xxx/Library/pnpm/global/5 Then your final path would be: /Users/xxx/Library/pnpm/global/5/node_modules/mcp-chrome-bridge/dist/mcp/mcp-server-stdio.js

  1. Replace the configuration below with the final path you just obtained
{
  "mcpServers": {
    "chrome-mcp-stdio": {
      "command": "npx",
      "args": [
        "node",
        "/Users/xxx/Library/pnpm/global/5/node_modules/mcp-chrome-bridge/dist/mcp/mcp-server-stdio.js"
      ]
    }
  }
}

Searching Database…

这是什么?Chrome MCP Server 可以把你的 Chrome 浏览器变成一个工具,让 Claude 等 AI 助手通过 Model Context Protocol(MCP)对其进行控制,在你日常使用的浏览器中直接实现浏览器自动化、内容分析和语义搜索。
这像是基于 Playwright 的 MCP 服务器吗,还是会使用我自己的 Chrome?它是一个 Chrome 扩展,配合本地的原生主机桥接程序(mcp-chrome-bridge)工作,直接接入你正在使用的 Chrome 浏览器,而不是启动一个单独的自动化浏览器实例,因此能保留你现有的登录状态、Cookie 和设置。
我该怎么把它运行起来,并连接到我的 AI 客户端?从 GitHub 下载扩展,通过 npm/pnpm 全局安装 mcp-chrome-bridge 原生主机,在开启开发者模式的 chrome://extensions 页面中加载已解压的扩展程序,然后打开扩展弹窗并点击连接,获取 MCP 配置(推荐使用 Streamable HTTP,也支持 STDIO)。
开始之前需要先安装什么?你需要安装 Node.js 20 或更高版本,并同时安装 npm 或 pnpm,还需要 Chrome 或基于 Chromium 的浏览器来加载扩展。
有哪些需要注意的不完善之处吗?项目仍处于早期阶段,正在大力开发中;pnpm v7+ 默认会禁用桥接程序的 postinstall 脚本,因此你可能需要手动注册它。Firefox 支持目前只是路线图中的计划,尚不可用。
我的浏览数据会被发送到别处吗?不会。它以完全本地运行的 MCP 服务器形式工作,浏览器活动在你自己的电脑上处理,而不会发送到远程服务。
为什么要用它,而不用基于 Playwright 的 MCP 服务器?因为它运行在你真实的、已经打开的 Chrome 中,几乎可以瞬间启动,复用你现有的登录会话,并且可以完整访问 Chrome 的原生 API,而不受 Playwright API 范围的限制。
内置的 20 多个工具具体能做什么?它们涵盖标签页和窗口管理、截图、网络请求捕获(包括通过 debugger API 获取响应体)、页面交互(点击、填写、键盘操作)、带语义搜索的内容提取,以及书签和历史记录管理。
语义搜索功能是如何工作的?它使用内置的本地向量数据库,并结合一个自定义的 WebAssembly SIMD 模块,将向量运算速度提升 4 到 8 倍,让你可以按含义而不是精确关键词搜索所有打开的标签页。
项目接下来有什么计划?路线图包括身份验证、录制与回放、工作流自动化,以及将支持范围从 Chrome 扩展到 Firefox。
