Chrome DevTools MCP

공식

공식 Chrome DevTools MCP 서버로, Gemini, Claude, Cursor, Copilot 같은 코딩 에이전트에서 라이브 Chrome 브라우저를 제어하고 검사할 수 있습니다.

Chrome DevTools MCP(으)로 무엇을 할 수 있나요?

  • 성능 추적 — 어시스턴트에게 URL의 성능 추적을 기록하고 실행 가능한 인사이트를 표시하도록 요청하세요(예: "https://developers.chrome.com의 성능을 확인해 줘").
  • 네트워크 분석 — 어시스턴트에게 네트워크 요청을 검사하여 로딩 문제, 실패한 리소스 또는 API 호출 문제를 디버깅하도록 하세요.
  • 콘솔 모니터링 — 브라우저 콘솔 메시지(소스 매핑된 스택 추적 포함)를 확인하여 JavaScript 오류를 진단하도록 요청하세요.
  • 스크린샷 캡처 — 어시스턴트에게 현재 페이지의 스크린샷을 촬영하여 시각적 검증 또는 문서화를 수행하도록 지시하세요.
  • 자동화된 브라우저 작업 — 어시스턴트에게 Puppeteer를 사용하여 클릭, 탐색 또는 양식 작성과 같은 상호작용을 자동화하고 결과를 자동으로 대기하도록 지시하세요.

Chrome DevTools for agents

npm chrome-devtools-mcp package

Chrome DevTools for agents (chrome-devtools-mcp) lets your coding agent (such as Antigravity, 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. A CLI is also provided for use without MCP.

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 browser console messages (with source-mapped stack traces).
  • 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.

chrome-devtools-mcp officially supports Google Chrome and Chrome for Testing only. Other Chromium-based browsers may work, but this is not guaranteed, and you may encounter unexpected behavior. Use at your own discretion. We are committed to providing fixes and support for the latest version of Extended Stable Chrome.

Performance tools may send trace URLs to the Google CrUX API to fetch real-user experience data. This helps provide a holistic performance picture by presenting field data alongside lab data. This data is collected by the Chrome User Experience Report (CrUX). To disable this, run with the --no-performance-crux flag.

Usage statistics

Google collects usage statistics (such as tool invocation success rates, latency, and environment information) to improve the reliability and performance of Chrome DevTools MCP.

Data collection is enabled by default. You can opt-out by passing the --no-usage-statistics flag when starting the server:

"args": ["-y", "chrome-devtools-mcp@latest", "--no-usage-statistics"]

Google handles this data in accordance with the Google Privacy Policy.

Google's collection of usage statistics for Chrome DevTools MCP is independent from the Chrome browser's usage statistics. Opting out of Chrome metrics does not automatically opt you out of this tool, and vice-versa.

Collection is disabled if CHROME_DEVTOOLS_MCP_NO_USAGE_STATISTICS or CI env variables are set.

Update checks

By default, the server periodically checks the npm registry for updates and logs a notification when a newer version is available. You can disable these update checks by setting the CHROME_DEVTOOLS_MCP_NO_UPDATE_CHECKS environment variable.

Requirements

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.

If you are interested in doing only basic browser tasks, use the --slim mode:

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

See Slim tool reference.

MCP Client configuration

For setup instructions specific to your editor or agent (e.g. Antigravity, Claude Code, Cursor, VS Code), please see our Client Configurations Guide.

Your first prompt

Enter the following prompt in your MCP Client to check if everything is working:

Check the performance of https://developers.chrome.com

Your MCP client should open the browser and record a performance trace.

[!NOTE] The MCP server will start the browser automatically once the MCP client uses a tool that requires a running browser instance. Connecting to the Chrome DevTools MCP server on its own will not automatically start the browser.

Tools

If you run into any issues, checkout our troubleshooting guide. See the full Tool Reference for a complete list of all supported MCP capabilities.

Configuration

Find the complete list of server parameters (e.g., --headless, --isolated, --slim) and how to configure WebSocket connections in the Configuration Guide.

Advanced Usage

For advanced features such as handling concurrent sessions, persistent user data directories, connecting to a running Chrome instance instead of starting a new one, or debugging on Android, see our Advanced Usage Guide.

Integrating as a browser subagent

If you are developing agentic tooling and want to provide an integrated browser subagent as part of your product, we recommend building on top of Chrome DevTools for agents.

For a reference implementation, see the Gemini CLI browser agent documentation.
