Is there a way to kill mob's via multicraft console?

[Boundary]

So i did a server restart earlier today & it decided to turn on 4 T5 spawners. By the time I had logged in there where 670 entities in my grinder area. I have tried logging in by client to disable the spawners but I get disconnected in a few seconds. Is there anyway I can kill them via the console in multicraft?

Thanks

Thanks, that worked perfectly!

While we are at it, is there a resource that gives all the console commands?
