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 Example video of how NoCheatPlus blocks cheats (outdated plugin version).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 had a random question, or actually more a request, if possibe ofc. Isn't it possible to cancel the usage of nocheat during a plugin useage? For instance using a plugin that would normally be canceld by nocheatplus, put the plugin in some sort of whitelisted plugin list for nocheat so it woudnt do anything if u use the plugin? Just a stupid question.

    Don't be too pessimistic :p - though it does apply here.

    @ItalianSkillz: Go

    It's not an error, it's a false positive, provided you were not using cheats, which is what i assume.

    The fight.knockback check is affected by network congestion and client side lag (mostly), so it actually applies here that a couple of violations are possible, just so.

    250 is not a high violation level for the knockback check, however we don't know what level you reached on that other server, or say... what data they based their decision on.

    If they can be talked to, i suggest you let them show and/or explain on base of what data you got punished there (Alerts or violation history? What check types involved? What violation levels within what time?). It's also possible to ask us here on BukkitDev (pm, ticket, main page) on specific data/outputs.


    Latest release (1.7.2-1.7.10, approved) NoCheatPlus 3.11.1-RC-sMD5NET-b743

    We clearly said that NoCheatPlus cant be perfect:
    "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)."
    Its not our fault if neither you or that server owner want to read. So again:
    YES! NoCheatPlus cant be always right and Minecraft itself isn't really designed to work smoothly with any AntiCheat plugin at all.

    Yea you run on a outdated version, If you run on 1.7.9 you should update to NC+ 390. That should fix your problem.

    Version of NoCheatPlus and CraftBukkit? Sounds like your NC+ is forced to use bukkitAPI only and cant properly shape all blocks.
