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 Example video of how NoCheatPlus blocks cheats (outdated plugin version).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

    Alright thanks. Can't judge it right now, can't make out a general reason yet (versions, confirmation),

    @mcly: Go

    NCP does not judge the distance from spawn, but we have general criteria/weights to make chat more "expensive" for "right after join" and for "not moving", which you can increase:

      (This one might be annoying to raise, because players usually don't move too much during chatting.)

    Is there a specific case you have in mind, or just "near spawn"? The chat checks are by no means complete/finished, i can't say how much more we will put in though, because there exist pretty good specialized plugins.

    Did you ask at GriefPrevention? They do have a couple of interesting concepts added in...

    @BrutalNetwork: Go

    That should be:

    Is there a permission i can give players to bypass the check for Autosign, if so what is it?

    @NK_FLASH: Go

    I'm asking how to configure NCP spam feature to achieve the purpose, not how to co figure GP, so I'm in the right place.

    This place isn't really a good place for an answer, check GriefPrevention's page.

    Yeah, I'm aware of that. But I don't use WG, I use GriefPrevention.

    @mcly: Go

    What I would do is create a WorldGuard region right at the spawn point. Then for that specific region set the "send-chat" flag to deny.

    Hello, thanks for making this neat plugin.

    Could you please let me know how can I configure NCP to block spam when player hasn't move away from spawn point?
