VSI offers:

ActiveMQ server + JVM client (JMS) - 
https://vmssoftware.com/products/activemq/

Mosquito (MQTT) server - https://vmssoftware.com/products/mosquitto/

RabbitMQ native client (librabbitmq) that I suspect will work with any 
server talking AMQP - https://vmssoftware.com/products/librabbitmq/

Client for MQTT protocol - https://vmssoftware.com/products/paho-c/

Outside of that:

JFP VMS Python (I have not checked VSI VMS Python) comes with
an AMQP module and it is possible to get the standard stomp
module working.

RabbitMQ JVM client should work on VMS if the Java version is new enough.

And for those wanting native access then there exist open source
C code for STOMP protocol (plus I have created VMS wrappers for
it - https://www.vajhoej.dk/arne/opensource/vms/ grab the vmspstomp
library).

So VMS does have something in this area.
