How to drive Chrome from the command line with the DevTools CLI skill with Chrome DevTools MCP

Use the CLI instead of MCP for quick navigate and screenshot jobs, and install it as a skill for your agent.

Short answer: Install globally: npm i chrome-devtools-mcp@latest -g; then open a page: chrome-devtools navigate_page 1 --url "https://developers.chrome.com"; Capture it: chrome-devtools take_screenshot 1 --filePath screenshot.png, then chrome-devtools stop. All steps.

Who it is forSomeone who wants scripted browser checks without loading MCP tool schemas into every chat.

The problemMCP tools cost context tokens even for simple screenshot jobs.

The outcomeShort CLI commands your agent or script can run to navigate and capture pages.

What you need first

  • Node.js and npm
  • Chrome
  • An MCP client or a coding agent that can run shell commands

Steps

  1. Install globally: npm i chrome-devtools-mcp@latest -g
  2. Open a page: chrome-devtools navigate_page 1 --url "https://developers.chrome.com"
  3. Capture it: chrome-devtools take_screenshot 1 --filePath screenshot.png, then chrome-devtools stop
  4. For Claude Code, copy the chrome-devtools-cli skill folder into ~/.claude/skills/

Prompt for your agent

Install ChromeDevTools/chrome-devtools-mcp globally, add the chrome-devtools-cli skill for my agent, and write a script that screenshots each URL in urls.txt into ./shots/.

Caveat.
