I had a history teacher in the school who used to say that the cheat sheets are allowed, but if he spots anyone using it, they will receive zero points for the test.
Same is here. By default all mods are allowed and it's your responsibility whether the mod you use gives you an advantage which is unobtainable without any mods (= cheat). So if this mod does exactly the same as specific serverside commands, you can theoretically use it... But if it contains any implicit features that give you an advantage, you will get banned. So I don't recommend using it, we have dozens of serverside animations (as CaniS said, use /anims to get the list) already.
