Chrome DevTools MCP

chrome-devtools-mcp lets your coding agent (such as Gemini, Claude, Cursor or Copilot) control and inspect a live Chrome browser. It acts as a Model-Context-Protocol (MCP) server, giving your AI coding assistant access to the full power of Chrome DevTools for reliable automation, in-depth debugging, and performance analysis.

Key features

Get performance insights: Uses Chrome DevTools to record traces and extract actionable performance insights.
Advanced browser debugging: Analyze network requests, take screenshots and check the browser console.
Reliable automation. Uses puppeteer to automate actions in Chrome and automatically wait for action results.

Disclaimers

chrome-devtools-mcp exposes content of the browser instance to the MCP clients allowing them to inspect, debug, and modify any data in the browser or DevTools. Avoid sharing sensitive or personal information that you don't want to share with MCP clients.

Requirements

Node.js v20.19 or a newer latest maintenance LTS version.
Chrome current stable version or newer.
npm.

Getting started

Add the following config to your MCP client:

{
  "mcpServers": {
    "chrome-devtools": {
      "command": "npx",
      "args": ["-y", "chrome-devtools-mcp@latest"]
    }
  }
}

[!NOTE]
Using chrome-devtools-mcp@latest ensures that your MCP client will always use the latest version of the Chrome DevTools MCP server.
