ModChecking
I don't know my version or loader
A unique combination of a mod and a server-side plugin to enforce mandatory mods.
The main idea and methods of application:
This is a client mod and a server plugin. It is very useful for servers that do not have mods, but you want to have client mods on the server. Access to the server is only allowed for the Fabric client and with a list of specific mods (at the discretion of the server owner).
registration of the list of required mods will be done by modid.
what if?
if the player logs in without the required mod, it will require them to install it
if the player logs in with a mod and the mods in the list, they will successfully log in to the server and be able to play
