Detect and fight the exploitation of various flaws/bugs in Minecraft!

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 Example video of how NoCheatPlus blocks cheats (outdated plugin version).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

    @ProdigyOG: Go

    Just removed them and unfortunately default players are still able to see the notifications >.<

    If I fly and press my sprint button, there will be knockback from ncp. Wrong values? It's very annoying. D: Using latest ncp & spigot 1.8

    @Duffa13: Go

    Do not give them ".silent" because that disables the logging for that player. Remove the ncp related permissions for normal players and see if the problem persists.

    NCP needs to become compatible with vanilla item attributes.

    My server has a +90% sword and NCP confuses it for unusual movement and cripples its usage. This really needs to be fixed.

    I have build: 3.12.0-SnapShot-sMD5NET-b802 and the players that have Depth Strider boots on keep making NCP go off. Do I need to set it up in any special way to allow them to use them?

    @asofold: Go

    I use PermissionsEX

    and these are the NCP permissions my default players have:

    - nocheatplus.checks.blockinteract.direction.silent - nocheatplus.checks.fight.direction.silent - nocheatplus.checks.inventory.drop.silent - nocheatplus.checks.fight.speed.silent - nocheatplus.checks.blockinteract.silent -

    @Duffa13: Go

    Do you grant them any NCP-related permissions by default? What is your permissions plugin?


    Latest release (1.7.2-1.7.10, approved) NoCheatPlus 3.11.1-RC-sMD5NET-b743
    (Development builds, 1.8: Jenkins)

    All default players are able to see NCP notifications such as failed checks. Is there any fix to this?

    All right, I have PM'd you about the details of kicking some players.

    @MasterGabeMOD: Go

    That resource usage doesn't seem problematic to me. Of course it's a lot, so disabling some things may or may not help, but basically the PostEnableTask is run once after enabling of plugins. The other one i am not sure about, but it's at 0.0k count, so there is little to say about that one either.

    @kangarkooo: Go

    The timings don't look frightening to me, the OnPlayerJOinLow is run too seldomly to affect anything much.

    @Exigopro: Go

    The permissions mean bypass-permissions, so if you grant a default permission, players can bypass checks. So for the usual case you should just not grant any ncp-related permissions.
