Is your feature request related to a problem? Please describe.
I would like to have a similar functionality on Velocity, as it is more secure than Bungee, and it would also be good to port it to Fabric, since there are no such server mods there. :/

Describe the solution you'd like
The ability to use the plugin in Velocity, and also, if possible (if there is of course an opportunity) to port to Fabric... with LuckPerms(mod version) support

I would love to do this and I have plans for it, but at the moment I simply don't have the time to finish it. I have it in the works at https://github.com/TreyRuffy/commandblockernew

Well, then I will wait :>
