GitHub Issue for 1.10 progress (overview)


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 Example video of how NoCheatPlus blocks cheats (outdated plugin version).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


Allows NoCheatPlus to activate packet-level checks, covering a range of exploits that can't be monitored using ordinary means. Since roughly Minecraft 1.7.10, the fight.speed check can't work as expected anymore, due to changes in CraftBukkit. With ProtocolLib this can be repaired.

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 create an issue/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". (Latest versions of Spigot contain features of Orebfuscator.)

    I didn't say AntiCheat doesn't work with 1.4.6. I said that its not compiled against 1.4.6 yet. I'm sure @asofold will update NoCheatPlus as soon as possible but that will take a bit of time of course.

    AntiCheat Works flawlessly on 1.4.6, I use it since NC+ isn't working.

    @Ta6akus4: Go

    I didn't force anyone here to stay on 1.4.5 I just recommend it because using CB development builds on new Minecraft update could corrupt/destroy things on your server. We cant immediately push a NoCheatPlus build out that works with Craftbukkit 1.4.6, @asofold has also a life so give him some time please.

    To note: AntiCheat is also not compiled/coded with 1.4.6 yet.

    Because NoCheatPlus uses other MCAccess methods then AntiCheat does. It will now break on every Minecraft update caused by this commit.

    It will take some time for us to update NoCheatPlus to the new 1.4.6 build of Craftbukkit. So please stay on 1.4.5 since its not smart to use one of the first development CB builds on a new Minecraft update.

    @Blackixx: Go

    Ok. Thanks :)

    @tiwar: Go

    Glad someone understands that :). Thanks
