Watch out for

• It can delete your automation rules

  delete_rule removes a rule outright. Review rule changes before asking the assistant to apply them widely. github.com

• It cannot send email, only draft it

  create_draft saves a new message in your Drafts folder; nothing sends automatically. github.com

• Disconnecting one app does not affect others

  Revoke access per app from Settings, Account, MCP, or turn MCP off entirely to end every connection. github.com

• Your mail passes through a hosted third-party service

  This is a vendor-hosted server: search results and thread text go from your mailbox through Inbox Zero to your assistant. Self-hosting the server is documented if you want it on your own infrastructure. github.com
