MuteSync is a simple plugin that allows you to mute players in-game when they are muted on your Discord server, and unmute them when they are unmuted on your Discord server.
This plugin uses DiscordSRV as the linking system between your Minecraft server and Discord server, so make sure that you have it installed and setup using the linking.yml file in DiscordSRV's configuration.
This plugin also uses LibertyBans as the mute system, so make sure that you have it installed and setup using the config.yml file in LibertyBans' configuration.
