Chrome Devtools Cli

chromedevtools/chrome-devtools-mcpOfficial

This is a CLI wrapper around Chrome DevTools Protocol that lets you automate browsers from the command line or scripts. You take snapshots to get element UIDs, then click, fill, or drag them around. State persists across commands, so you can chain actions without ceremony. It handles the stuff you'd expect like navigation, screenshots, and network inspection, plus less common needs like Lighthouse audits, performance traces, and heap snapshots. The snapshot approach is smarter than raw DOM selectors since it uses the accessibility tree. If you're building browser automation that needs to be scriptable or want DevTools power outside the GUI, this does the job without fighting Selenium.

Setup

Note: If this is your very first time using the CLI, see references/installation.md for setup. Installation is a one-time prerequisite and is not part of the regular AI workflow.

AI Workflow

Execute: Run tools directly. If you don't know the target page's ID, run chrome-devtools list_pages to find it. The background server starts implicitly; do not run start/status/stop before each use.
Inspect: Use chrome-devtools take_snapshot <pageId> to get an element <uid>.
Act: Use chrome-devtools click <pageId> <uid>, chrome-devtools fill <pageId> <uid> <value>, etc. State persists across commands.

Snapshot example:

uid=1_0 RootWebArea "Example Domain" url="https://example.com/"
  uid=1_1 heading "Example Domain" level="1"
