MCMT inclusion

[josejsarmento]

How do I add a mod such as MCMT? Would such a thing even work?

Have you read through https://github.com/itzg/docker-minecraft-server#working-with-mods-and-plugins ?

I am skeptical though of what that mod is attempting to do. If you're really wanting to improve server performance then I suggest using Paper.
