What products from Mulesoft? They have a lot! We have a nice extension that monitors Mulesoft Cloudhub, and you can see some details here https://www.dynatrace.com/hub/detail/mulesoft-cloudhub , you also can send an email to email@example.com with more details and we can help you from there.
If it uses Cloudhub, only remotely (AG extension for example) as Mulesoft does not allow customers to change the container images they run, so you can't install an OneAgent.
I know that some Mulesoft customers have developed ways to get more insight remotely via JVM TI, but this is something you would need to discuss with Mulesoft further
