Run mongo-dev-server(project dev local mongo) as temporary use

Q.
How to use mongo-dev-server, internal MongoDB in Meteor,
when I use external MongoDB with ‘export MONGO_URL’?

Explain.
I understand MongoDB must be used fully installed MongoDB version on production mode.
But sometimes I need a temporary DB locally for performance in Scaled out service.

In this case we could set up local mongodb as well,
but it would be easy to use mongo-dev-server just for temp DB.
