An MCP server and a Chromium extension that let your agents use your real browser, with your tabs, your logins and your extensions. They open and drive tabs with Playwright, take screenshots and record the screen, in background tabs grouped out of your way. When it's your turn, for a login, a 2FA prompt or a payment, they hand the tab back to you and continue once you click Continue.
