Faster Chrome DevTools: direct CDP

Use the bundled CLI to control Chrome through the Chrome DevTools Protocol (CDP). It connects directly to Chrome's browser WebSocket with Node.js built-ins. There is no MCP server, Puppeteer install, Playwright install, or package install.

node <skill-directory>/scripts/cdp.mjs --help

Replace <skill-directory> with the directory containing this SKILL.md. Node.js 22 or later is required.

Before connecting

Local Chrome access exposes the user's open tabs and logged-in browser state. Obtain the user's approval before inspecting or interacting with their browser. Ask them to enable remote debugging at chrome://inspect/#remote-debugging if it is not already enabled. Chrome may also show an Allow debugging prompt.
