Puoi fare...
JavaScript (shell):
db.getCollectionNames()
Node.js:
db.listCollections()
Non JavaScript (solo shell):
show collections
Il motivo per cui lo chiamo non JavaScript è perché:
$ mongo prodmongo/app --eval "show collections"
MongoDB shell version: 3.2.10
connecting to: prodmongo/app

$ mongo prodmongo/app --eval "db.getCollectionNames()"

Se vuoi davvero quel dolce, dolce show collections output, puoi:
$ mongo prodmongo/app --eval "db.getCollectionNames().join('\n')"
