Music Player Daemon with mopidy as a media player question

Does Music Player Daemon (MPD) support only media_content_type: playlist for mopidy media player?
I am trying to use media_content_type: music with a single song in my script but it doesn’t seem to work.

I know that I can create a playlist with a single song, but just want to know if this content type is supported.

It looks like it needs URIs like these:

media_content_id: 'file:///media/music/Moonlight.mp3' for ‘Files’ (Mopidy-Files)

and

media_content_id: 'local:track:Moonlight.mp3' for ‘Local media’ (Mopidy-Local)

That means this integration doesn’t search/browse mopidy for the URI. But I might be wrong.
