gmail_mcp is a private tool. It lets its owner's AI assistant search, read and organise mail in the owner's own Gmail accounts. It runs on the owner's computer.
It is not a public service. It has no sign up, it is not offered to anyone else, and nobody other than its owner has a reason to authorize it.
With the owner's permission it can search and read messages, add and remove labels, move messages to the trash, write drafts and send a draft the owner has approved. It cannot permanently delete mail.
With the owner's permission it can read calendars and events. It cannot create, change or respond to an event.
Unless you are the owner, do not continue. Close the page.
