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

Features Permissions Commands Configuration Jenkins

NOW! With Minecraft 1.10 support! (on Jenkins)

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 Example video of how NoCheatPlus blocks cheats (outdated plugin version).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 will update (NO GUARANTEES).

    But sincerely, since the new safeguard-change people seem to expect us to update even faster. It is like 9:17 am here and the FIRST dev build of CraftBukkit is hardly 16 hours old, am i wrong?

    Updates will be on Jenkins (soon) until i have the impression that CB stays stable enough and they have a version tag for an upload on BukkitDev.

    @ProMCer: Go

    NoCheatPlus will break now on every Minecraft update that comes out since bukkit decided to go this way now. More HERE.
    You will have to wait for a 1.4.6 NoCheatPlus build now.

    Cant believe how many people are demanding a 1.4.6 instead of patiently waiting on it. Instead I'd like to say thank you to the developers of NCP for your continued dedication to this project! Have sent off a donation your way as well! Happy Holidays and take your time :)
