Connects Claude Code or Codex CLI directly to your live Chrome browser via the Chrome DevTools Protocol, preserving your logged-in sessions and open tabs. Exposes 28 browser tools covering navigation, element interaction, screenshot capture, cookie and localStorage manipulation, and JavaScript execution. Reach for this when you need an AI coding assistant to test web apps in a real browser context, automate authenticated workflows, or debug UI issues without spinning up headless instances. The session persistence means Claude can work with sites where you're already logged in, which beats constantly re-authenticating in throwaway browser contexts.
