mdq-server is just an MDA application, in the sense of an application that
uses the MDA framework. It generates the JSON you are referring
to by implementing an MDA Stage to generate the output and including it in
the configuration. You could easily use that same stage in a configuration
invoked by the mda.sh CLI instead.
