Can I run a Postman mock server on a higher environment other than localhost?

We worked on some third party banking APIs, for which we needed to set up a mock server for each of our environments(integration, QA and pre-production). We used mountebank - to build the mock web server. It got a bit tedious as the configuration for each of the APIs was based on a lot of inputs selected.

I was wondering if any one has used the postman web server on a higher environment or does it currently support a locally running mock server only?
