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

Main 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 Example video of how NoCheatPlus blocks cheats (outdated plugin version).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".

    in the settings disable console & chat warnings, this wills top the spam and messages in console and in game, it will still block users for doing hacks so dont worry about that

    Many thanks from the MineZ development team. We threw some money your way to help with server costs. I recommend any other server who uses NoCheatPlus do the same, as you know how miserable multiplayer servers would be without the NoCheatPlus team.

    Build 83 introduces a new fast break check, aimed at allowing realistic breaking times, especially instantly breakables should not pose problems anymore, most config for it is hidden, however. It can be switched for the old one, if desired. The InstantHeal check is now disabled by default, the WrongBlock check was improved to prevent accumulation of seldom triggers.

    This build is considered feature complete for beta and probably slightly further. From now till release we will only do fixes and updating of the documentation and configuration changes for balancing.

    @457undead: Go

    It is the actions entry for the check that is alerting.

    If you have "actions: log:somename:0:5:icf cancel" as the first entries,

    you can do "actions: cancel vl>8 log:somename:0:5:icf cancel", which would still cancel actions but start the logging after violation level of morethan 8. That would only adjust the logging.

    Alternatively you can remove the "i" at the end of the log entries to not log those to ingame chat.

    Disable the check or increase the violation level for logging (vl>7 before the log:...).

    @PhanaticD: Go

    Did you update before disabling the checks?

    Seems somewhat unlikely, though it can always be something indirect with commands involved and logging.
