Google's official Chrome DevTools MCP server — gives AI agents full control of a live Chrome browser via Puppeteer and the Chrome DevTools Protocol.
Features
- Input automation — click, drag, fill forms, hover, press keys, upload files, handle dialogs
- Navigation — open/close/switch pages, wait for elements/network idle
- Screenshots & snapshots — capture page state visually and as DOM
- Performance traces — record and analyze Chrome performance traces with insights
- Network inspection — list/inspect network requests and responses
- Console debugging — read console messages with source-mapped stack traces
- Device emulation — emulate mobile devices, resize viewport
- Form automation — fill multiple form fields at once
Requirements
- Node.js v20.19+ (already available in OpenClaw)
- Chrome/Chromium browser
Quick Start
Install & verify
npx -y chrome-devtools-mcp@latest --help
Start the MCP server
# Standard (launches Chrome automatically)
npx -y chrome-devtools-mcp@latest# Headless mode (for servers)
npx -y chrome-devtools-mcp@latest --headless
# Connect to existing Chrome (must be started with --remote-debugging-port=9222)
npx -y chrome-devtools-mcp@latest --browser-url=http://127.0.0.1:9222
# Disable telemetry
npx -y chrome-devtools-mcp@latest --no-usage-statistics --no-performance-crux
OpenClaw MCP Integration
Add to your openclaw.json under MCP servers:
{
"mcp": {
"servers": {
"chrome-devtools": {
"command": "npx",
"args": ["-y", "chrome-devtools-mcp@latest", "--headless", "--no-usage-statistics"]
}
}
}
}
Or use the setup script:
python3 {baseDir}/scripts/setup_chrome_mcp.py setup
python3 {baseDir}/scripts/setup_chrome_mcp.py status
python3 {baseDir}/scripts/setup_chrome_mcp.py test

Privacy Notes
- Google collects usage statistics by default — disable with
--no-usage-statistics
- Performance tools may send trace URLs to Google CrUX API — disable with
--no-performance-crux
- Avoid sharing sensitive data in browser sessions
