Detect and fight the exploitation of various flaws/bugs in Minecraft!

Features Permissions Commands Configuration Jenkins


NoCheatPlus attempts to prevent cheat clients from exploiting weaknesses of Minecraft or its protocol, making your server more safe. Checks cover a wide range of issues including flying and speeding, fighting hacks, fast block breaking and nukers, inventory hacks, chat spam and other types of malicious behaviour. For a more complete list have a look at the Features Page.

NoCheatPlus puts emphasis on configurability and allows you to customize actions that are carried out when a player fails a check (e.g. silent cancelling, executing commands, just logging). Bypass permissions allow to control what check to apply for which players, all checks can be deactivated in the configuration, also having the option for world-specific configuration files. Many checks allow more detailed configuration to adjust sensitivity.

Certainly NoCheatPlus is not a magical bullet, it uses a lot of heuristics and even guessing, so you will encounter false positives here and there and also not catch every single violation. Example video of how NoCheatPlus blocks cheats (outdated plugin version).

NoCheatPlus was introduced by NeatMonster, building on the code base of NoCheat by Evenprime.

The following plugins might be useful to have a look at.

CompatNoCheatPlus (cncp)

Make plugins like mcMMO, Citizens, MagicSpells or MachinaCraft more compatbile with NoCheatPlus. Not all existing plugins are covered (yet), but you can leave a note or ticket request for cncp.


Orebfuscator fights all sorts of X-ray-hacks by altering the map information that is sent to the players, such that they have to mine blocks to actually reveal what is behind. Virtually a "must have".

    Same answer from my side - please open a ticket for cauldron support.

    The block types might be dífferent, if you have modded tools, things will be even more complicated... this will get lost on the main page.

    @Red_Jay: Go

    I'm having the same "rubber banding issue" and I use cauldron 1.7.2 Is there a build that is stable for cauldron?

    @Crazydoc134: Go

    I think we should put that to a ticket, becaus mods are hard to make compatible.

    If you don't want to exempt all players from flying checks, you might need to tweak the "blockflags" settings.

    Still we need the output of "ncp version", at least server/MC and NCP versions.

    @asofold: Go Simply, players without having OP can barely walk.They get teleported back.

    @Crazydoc134: Go

    That might become complicated, can you confine it to certain kinds of blocks to walk on?

    Players cannot move using the latest version of NCP in Modded/Cauldron server.It gives false errors that they are trying to fly.

    @CKGAR: Go

    I would never suggest to bypass all checks, but go by distinct alerts and/or the output of /ncp info player" rather.

    The permission to bypass most stuff is nocheatplus.checks,. However disabling checks in an arena means that you enable all sorts of split-second-aura-kill-things and flying, so i would suggest to just tweak the checks to prevent the worst instead of blunt disabling.

    Is there any way that in my pvp arena, which is in a different world from my spawn, that I can disable checks in that world? Is there a parent permission for all checks to be disabled?

    @Red_Jay: Go

    I don't think such can simply be "fixed" by a config setting. Is it an occasional issue or does it always happen, to all players?

    Best post output of the "ncp version" command, so we can quickly see, if there is a version incompatibility. E.g. running on 1.7.10 you would need a development build of NCP for now.
