GuardAC is a cloud anti-cheat for Minecraft servers that looks for KillAura, aim assist and unusual combat crosshair movement. A server plugin sends the cloud service a short set of movement measurements rather than video, and the system learns each player’s usual mouse style to flag changes during a session. Players install nothing. Staff can receive alerts with a player name and score, review logs, and choose manual or automated enforcement. Configurable thresholds range from alert-only operation to automatic bans; actions include kicks, bans, broadcasts, console commands and optional combat suppression. Replay analysis is also listed. The plugin supports Paper, Spigot, Purpur and Folia servers running Minecraft 1.16 or newer. Servers need Java 17 or newer, while Minecraft 26.1 and 26.2 require Java 25. The service pairs the plugin with a cloud API accessed by API key. A free plan is listed at 0.00 USD per free, and a free-trial key is available after sign-up without a card.
