NoCheatPlus

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

Features Permissions Commands Configuration Jenkins

Introduction

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 Example video of how NoCheatPlus blocks cheats (outdated plugin version).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

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".

    @time6628: Go

    Build 771 might fix it. Could be that we have to adjust further or that it allows too much on other efficiency tools.

    Can you fix melon blocks being broken with axes, please? On 1.8 when you try to break them it classifies it as FastBreak.

    Thanks for great work on #769 :). If you mind fixing slime blocks (getting NoFall false positives) it would be awesome. If you are already aware then ignore this

    @pielord17: Go

    Will be added soon, unfortunately build 768 still needs adaption for sprinting+strider, and the Jenkins/cloudflare seems to be inaccessible fro me right now. It'll be on soon (check foor development buiild 768 or later).

    I believe the Depth Strider enchantment is blocked by NCP.

    @DerekZil: Go

    Yeah thats a new feature in 1.8 which requires changes in CreativeFly check, you can change the speed in your NoCheatPlus configuration file under moving and then creativefly. You want to edit the Vertical and horizontal speeds here till we add support for CTRL flying.

    @cillic1052: Go

    Yeah use the latest development build to add block data and shapes for MC 1.8.

    @Bronzeteufel: Go

    Not tested yet but you can try to put them in your configuration file under "ignorepassable "which you find under the compatibility category of the config. This will make the passable check ignore them for now till we have a proper fix.

    @cillic1052: Go

    That just means the version you're using doesn't have the data for the 1.8 blocks. It will still work, but if a player tries to use a faster block break hack on those materials, NCP won't be able to tell. The newest successful on Jenkins seems to have the correct data.

    The block breaking data is incomplete, default to allow instant breaking here is a screenshot
