Mustard Mail MCP privacy

This private email integration accesses its owner’s connected Gmail account to read message summaries, search email, and send requested messages.

Google authorization credentials are kept in encrypted Cloudflare Worker secrets. Email remains in Gmail and is returned to authenticated MCP clients when requested. This application does not keep a separate email database, sell email data, or use it for advertising. Application request logging is disabled.

Google delivers sent messages to approved recipients and their email providers. Authenticated MCP clients receive requested email information and process it under their own policies. Cloudflare hosts the server; Google provides mailbox access.

The owner can revoke Google access in Google Account connections and revoke MCP credentials in Cloudflare. This service is for its owner, with no public registration.
