Gmail MCP (Claude) is a personal tool used only by its owner. It lets the owner search, read and organize their own Gmail from their own computers using Claude. It is not offered to anyone else.
Mail is read on the owner's own computers and is not sent to or shared with any service run for this app. Messages the owner asks Claude to read are passed to Claude, made by Anthropic, as part of that conversation. The app collects no data from anyone else, and it does not sell or advertise with any data.
Access tokens are stored only on the owner's computers. Access can be revoked at any time from the Google Account's third-party access page.
