Drop in the plugin, paste your key - and GuardAC protects your server.
GuardAC requires the PacketEvents plugin. Download it and drop the .jar into plugins/.
Download the jar for your Java and drop it into plugins/ next to PacketEvents. Java 21 for modern servers (1.20.5+), Java 17 for older ones.
Start once so plugins/GuardAC/ with its config is created.
Open plugins/GuardAC/config.yml, put your key in ai.api-key, save and run /guard reload.
/guard monitor - watch checks live in combat. /guard stats - overview. /guard menu - suspects menu.
Paper / Spigot 1.16 or newer, Java 17 or newer.
Minecraft 26.1 and 26.2: the server needs Java 25+ and PacketEvents 2.13+. The GuardAC jar is the same one - nothing to change.
