What are your requirements for MQ, any specific queueing system, how much data do you expect in the messages, what systems will be receiving the messages?
There are a few options, ZeroMQ is one, MQTT is another queueing system that can be used from mendix: https://marketplace.mendix.com/link/component/119508
Alternatively you can use a queueing system that provides REST APIs for publishing and consumption.
As of 9.18 Mendix provides Business Events: this allows you to publish events and subscribe to events from other apps. With this solution you don’t have to think about the technical aspects of messaging, that is completely handled by Mendix.
