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 Example video of how NoCheatPlus blocks cheats (outdated plugin version).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

    The walkspeed you told me to use worked for a little while but then according to our players has now made the issue twice as bad. I really need a fix to this bug and i'm sure many others do too that's why GontrollerPVP used a custom version to fix the issue.

    @danyeye: Go

    What log alerts (ingame, console , nocheatplus.log) are there?

    Do you run special plugins like mcMMO (or other skills) gun plugins, arenas etc?

    @danmark2312: Go

    I don't see lag in that data. Also the number of events monitored is very low, so a reliable statement is not really possible.

    Do you happen to have noticable lag on the server? Do players get set-back during moving?

    Hello, I've recently got the Plugin. Right after getting it, Players could NOT attack mobs. Help? I've researched everywhere, NOTHING. Respond ASAP, I'm getting complaints from the players on my server.

    Thanks for the ticket link. I 'upvoted' it, as you suggested.

    Yes it is noletter. Of course it also makes any other posts with non-letters more expensive, so it is a two-bladed thing. You can also increase the repeatself value, though that may be annoying for answering "yes" simply.

    The other possibility for "slow" spamming would be to activate prefixes or against simple repetition the words engine for players (rather not global for this case). That would make repetition of several words more expensive, however it also raises the overall average level/cost for messages.
