Mod Menu is a harmless mod that does not change game play at all. All it does is gives you a list of the mods you currently have installed and weather to enable or disable them. It does not affect game play. It just lists which mods you have on.

The mods that we have approved are quality of life mods, such as optifine and bobby. Most other mods are banned for giving players an unfair advantage in which shaders and artificially increased render distance do not.
