How to Set Up and Use Chrome
Chrome MCP Server is an extension-based MCP integration that lets AI assistants directly control your Chrome browser, reusing your existing sessions and login states without any re-authentication. It exposes over 20 tools covering navigation, tab management, form interaction, screenshot capture, network monitoring, and semantic content search across open tabs. This makes it ideal for automating web workflows, scraping authenticated pages, debugging network requests, and running AI-driven browser tests — all processed locally with no external API calls.
Prerequisites
- Node.js 20.0.0 or newer with npm or pnpm installed
- Google Chrome or Chromium browser
- An MCP client such as Claude Desktop, Cursor, or Cline
- The mcp-chrome-bridge npm package installed globally
- The Chrome extension downloaded from the GitHub releases page
Install the bridge package globally
Install the mcp-chrome-bridge package globally using npm or pnpm. This bridge process handles communication between your MCP client and the Chrome extension.
npm install -g mcp-chrome-bridgeDownload and load the Chrome extension
Download the latest extension zip from the GitHub releases page at https://github.com/hangwin/mcp-chrome/releases. Then open Chrome, go to chrome://extensions/, enable Developer mode, click 'Load unpacked', and select the extracted extension folder.
Connect the extension
Click the Chrome MCP Server extension icon in your browser toolbar and click 'Connect'. The extension will start listening for commands from your MCP client on port 12306.
Configure your MCP client (Streamable HTTP — recommended)
Add the Chrome MCP server to your MCP client configuration. The recommended transport is Streamable HTTP which connects to the local server started by the extension.
{
"mcpServers": {
"chrome-mcp-server": {
"type": "streamableHttp",
"url": "http://127.0.0.1:12306/mcp"
}
}
}Verify the connection
Open your MCP client and ask it to list the available browser tools or take a screenshot of the current tab. The server should respond with the active Chrome tab content.
Chrome Examples
Client configuration
Streamable HTTP configuration for Claude Desktop or any MCP client that supports the streamable HTTP transport.
{
"mcpServers": {
"chrome-mcp-server": {
"type": "streamableHttp",
"url": "http://127.0.0.1:12306/mcp"
}
}
}Prompts to try
Example prompts that demonstrate the browser automation and content analysis capabilities of this server.
- "Take a screenshot of my current browser tab and describe what you see"
- "Search all my open tabs for anything related to 'authentication errors' and summarize the findings"
- "Fill in the login form on the current page with username '[email protected]' and submit it"
- "Capture all network requests made on this page and show me any failing API calls"
- "Click the 'Sign up' button on the current page and take a screenshot of the result"Troubleshooting Chrome
MCP client cannot connect to http://127.0.0.1:12306/mcp
Make sure the Chrome extension is installed and you have clicked 'Connect' in the extension popup. The extension must be connected before the server becomes available. Check chrome://extensions/ to ensure the extension is enabled.
Extension loads but shows 'disconnected' status
Ensure mcp-chrome-bridge is installed globally and is accessible on your PATH. Run 'which mcp-chrome-bridge' or 'npm list -g mcp-chrome-bridge' to verify. If using pnpm, also run 'pnpm config set enable-pre-post-scripts true' before installing.
Screenshots or tab content return empty results
Chrome extensions cannot access chrome:// or edge:// internal pages or pages with strict Content Security Policies. Navigate to a regular web page (http/https) and try again. Also ensure the extension has the necessary permissions granted in chrome://extensions/.
