all modern mcp clients support oauth — just add this server url:

        

          https://unthinkmail.undivisible.dev/mcp
        

        
your client will automatically open an authorization page where you enter your imap credentials. no manual key needed.

security

        
your credentials are never stored — they're encoded into the access token itself and decrypted per-request. use an app-specific password if your provider supports it (gmail, outlook, fastmail, and icloud all do). to revoke access, just disable the app password at your email provider.
