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.
Unless you are the owner, do not continue. Close the page.
