## 🎯 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.
## ✨ New Features(2025/12/30)
- **A New Visual Editor for Claude Code & Codex**, for more detail here: [VisualEditor](docs/VisualEditor.md)
## ✨ Core Features
- 😁 **Chatbot/Model Agnostic**: Let any LLM or chatbot client or agent you prefer automate your browser
- ⭐️ **Use Your Original Browser**: Seamlessly integrate with your existing browser environment (your configurations, login states, etc.)
- 💻 **Fully Local**: Pure local MCP server ensuring user privacy
- 🚄 **Streamable HTTP**: Streamable HTTP connection method
- 🏎 **Cross-Tab**: Cross-tab context
- 🧠 **Semantic Search**: Built-in vector database for intelligent browser tab content discovery
- 🔍 **Smart Content Analysis**: AI-powered text extraction and similarity matching
- 🌐 **20+ Tools**: Support for screenshots, network monitoring, interactive operations, bookmark management, browsing history, and 20+ other tools
- 🚀 **SIMD-Accelerated AI**: Custom WebAssembly SIMD optimization for 4-8x faster vector operations
## 🆚 Comparison with Similar Projects
| Comparison Dimension | Playwright-based MCP Server | Chrome Extension-based MCP Server |
| ----------------------- | ------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------ |
| **Resource Usage** | ❌ Requires launching independent browser process, installing Playwright dependencies, downloading browser binaries, etc. | ✅ No need to launch independent browser process, directly utilizes user's already open Chrome browser |
| **User Session Reuse** | ❌ Requires re-login | ✅ Automatically uses existing login state |
| **Browser Environment** | ❌ Clean environment lacks user settings | ✅ Fully preserves user environment |
| **API Access** | ⚠️ Limited to Playwright API | ✅ Full access to Chrome native APIs |
| **Startup Speed** | ❌ Requires launching browser process | ✅ Only needs to activate extension |
| **Response Speed** | 50-200ms inter-process communication | ✅ Faster |
## 🚀 Quick Start
### Prerequisites
- Node.js >= 20.0.0 and pnpm/npm
- Chrome/Chromium browser
### Installation Steps
1. **Download the latest Chrome extension from GitHub**
Download link: https://github.com/hangwin/mcp-chrome/releases
2. **Install mcp-chrome-bridge globally**
npm
```bash
npm install -g mcp-chrome-bridge
```
pnpm
```bash
# 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.
3. **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 configuration

### Usage with MCP Protocol Clients
#### Using Streamable HTTP Connection (👍🏻 Recommended)
Add the following configuration to your MCP client configuration (using CherryStudio as an example):
> Streamable HTTP connection method is recommended
```json
{
"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
```sh
# 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
2. Replace the configuration below with the final path you just obtained
```json
{
"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"
]
}
}
}
```
