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 Example video of how NoCheatPlus blocks cheats (outdated plugin version).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

    I just found a problem about this plugin. I spammed and it warned me. Then I just keep spamming. Finally I got kicked. But then me and other players can't join the server any more. And I tried to type some commands in consle. It relied Nothing. I even can't stop the server. (PS: My Server can't banip.Cuz Everyone joins my server throughy outer net to my intranet.Then everyone will be banned.) Hope someone can help me!

    Its probably the velocity fly @asofold and other velocity abuse. Seems they started to spread hardcore.

    I can't judge it. Are you running the lates version of NCP ?

    You should make a ticket, stating the output of the "ncp version" command, including some more info on what players do (tons of what actually), if you have observed it (or by hearsay), maybe the configuration as a paste. Are there any errors or warnings from NCP in the logs? Is there anything special to the servers (e.g. special mods)?


    Latest release (1.7.2-1.7.10, approved) NoCheatPlus 3.11.0-RC-sMD5NET-b739
    (Development builds: Jenkins)

    Players are still flying on all servers, and bypassing a ton of cheats. Using the latest version. Used to block this stuff not sure what happened after the uuids though. Are we doing something wrong? No errors, on 1.7.10, latest ncp.

    @niknea: Go

    You can use temporary exemption:

    You just call exemptPermanently for the check type(s) and when done unexempt(check type(s).

    Hooks might also be a way, however they get called after check failures (as described on the hooks page):

    How would I use that method (the exemption method). As I cant see the class itself, is it an event? How would I use it?

    Thanks, Niknea
