The extensible, customizable, self-documenting real-time display editor.

A more elegant, controlled way (though it would involve more work) would be to use the gpgme library to verify the signature. To do so, pass a prefix argument to mc-insert-public-key. gpg: keyserver receive failed: No data. Signing files with any other key will give a different signature.
