hey! although this would be pretty cool, majority of mcc uses either LabyMod, BadlionClient, or LunarClient. there ofc are other clients, but these are the most common ones I see, maybe check them out. I personally prefer badlion since there's a lot of features and cosmetics are cheaper, but LabyMod has lots of features, almost too many sometimes.. and I don't know that much about Lunar, but i've heard it's great hope this helped have a great day
I'd personally recommend Lunar Client. Although all of them are fairly equal in my opinion.\ I don't really think there is a point to creating a MCC client as its not really a direct pvp server. It still could be done but there isn't really a purpose beside defeating hackers which would be pretty neat to be honest
