Minecraft server-side anti-cheat
Minecraft Java Edition does not install a client-side anti-cheat. Cheat protection in multiplayer comes from server-side plugins on community servers; NoCheatPlus, Vulcan, Grim, and Matrix are the most-used. Authentication is handled by the Mojang / Microsoft Account system at login.
There is nothing on your machine for it to see, because nothing is installed there. Minecraft Java Edition ships no client-side anti-cheat; on a multiplayer server, the server's own plugins judge what your client sends them. The trust boundary lives on the server, not on your PC.
Catalogued by Vera from the anti-cheat maker's own documentation and named public reporting (Ars Technica, PC Gamer, Eurogamer, BleepingComputer, and others). Anti-cheats change; these notes reflect the public record as of June 2026. What is here is public evidence, never an accusation about a person.
