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 Example video of how NoCheatPlus blocks cheats (outdated plugin version).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

    @killerboss707: Go

    Misunderstood the issue.

    • So you make changes to the configuration and after reloading the configuration is as before?
    • Does that only happen with the logging "protection" section or also with other parts?
    • What's the output of the "ncp version" command ?

    @killerboss707: Go

    You can use the paste ( and set language to YAML, then post the link, it'll show the spaces right. Or use the code tags that i have mentioned below (@asofold: Go).

    Looks like part of the check is active and the commands are specified in there.

    • Have you tried just adding "pl" to the list of commands? Usually NCP should detect aliases and treat them alike, but there may be circumstances when that doesn't work.
    • What's the output of the "ncp version" command?

    @killerboss707: Go

    The configuration of NCP has a section under the key "protection". I would like to see that, you could send it by private message (pm). To make it better viewable enclosing it in code tags would be good. If it's not so secret, you can also post it here.

    Wait what... I did not get a word you said. :P what do u mean by pm, and with the rest? sorry about this...

    @killerboss707: Go

    Can you pm the part of the config (protection: ...), just with

    <<code YAML>>...<</code>>

    (The ... should be the protection section in a new line, doesn't display as usual.)

    Just 1 more thing. how come whenever I change like the messages in the config and I reload my sevrer the messages say for example: /pl i changed that to say like "You do not have permission for this command." Then i reload my server then i try /pl but the default message comes. I also tryed /ncp reload. Plz help. That goes for every command like /pl and /op...
