🌐 Chrome DevTools MCP

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
