How to actually access MB database with this tool?

[orkenstein]

The documentation states that:

Alternatively, if you are not interested in having a local MusicBrainz website and web service, you can use mbdata that includes replication without the rest of MusicBrainz Server.

But how to get the replica itself? The README includes:

>>> engine = create_engine('postgresql://musicbrainz:[email protected]/musicbrainz', echo=True)

Is this local existing database? If yes how to spin it?
To have a fully functioanl MB-server? In such case it doesn't match with the original docs.
