About MCP-B Agent

Give your AI agent a browser. Think Browser Host helps you get work done across the websites, services, and files you already use. Ask it to research across tabs, organize your browser, work with connected apps, create files, or repeat a task on a schedule. You can: - research and take action across multiple tabs; - organize tabs, bookmarks, history, and downloads; - work with Gmail, Google Calendar, Google Drive, and other connected services; - create reusable skills, scripts, conversations, and files; - choose local folders for a task; and - schedule recurring routines. You stay in control. Browser actions are visible, sensitive changes follow your approval settings, and sign-in or other human-only steps wait for you in the affected tab. Turn one-off work into reusable skills and routines, then run them again whenever you need them. Sign in with ChatGPT to get started. Connected services and local folders are optional—you choose what the agent can use.
