You can specify clshow=!hidden to omit the "hidden" categories that, by default, are not shown at the bottom of a page:

Is there a way to do this for action=parse so that only a single query needs to be made? I noticed that asking action=parse for the categories in html shows had tags with the hidden status encoded in them, but the XML returned in the categories does not mark hidden categories. 

Thanks,
