Given that dynamic UI controls such as  Dynamic Parameter and Uno-Choice 
<https://github.com/biouno/uno-choice-plugin> only support groovy, I think 
it may be worthwhile investigating how groovy can be used to access 
MongoDB. 

To start with I would consider using the gmongo 
<https://github.com/poiati/gmongo> wrapper to MongoDB.
