Setup
Install Chrome MCP Server in your MCP client (Claude Desktop, Cursor, Windsurf, and others).
Repository: https://github.com/hangwin/mcp-chrome
Follow the installation instructions in the repository README, then restart your MCP client.
🌟Turn your Chrome browser into your intelligent assistant- Let AI take control of your browser, transforming it into a powerful AI-controlled automation tool.
The project is still in its early stages and is under intensive development. More features, stability improvements, and other enhancements will follow.
Chrome MCP Server is a Chrome extension-basedModel Context Protocol (MCP) serverthat 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 Serverdirectly 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.

# 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. Theenable-pre-post-scriptssetting controls whether pre/post install scripts run. If automatic registration fails, use the manual registration command above.
- Load Chrome Extension
- Open Chrome and go tochrome://extensions/
- Enable "Developer mode"
- Click "Load unpacked" and selectyour/dowloaded/extension/folder
- Click the extension icon to open the plugin, then click connect to see the MCP configuration
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
{ "mcpServers": { "chrome-mcp-server": { "type": "streamableHttp", "url": "http://127.0.0.1:12306/mcp" } } }
If your client only supports stdio connection method, please use the following approach:
- 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
- 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" ] } } }
