About NoCheatPlus


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

Minecraft 1.11.2 and latest features are currently only available on Jenkins - once things stabilize, stable builds will be available here again.


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 Example video of how NoCheatPlus blocks cheats (outdated plugin version).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 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. Phasing out: Citizens 2 should work with NCP out of the box, MagicSpells are working on compatibility too - rest will be integrated into NCP.


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.)

NoCheatPlus 3.15.1-RC-sMD5NET-b1084


Recommended release for MC 1.11.2, possibly down to 1.4.5-R1.0 - please report issues to:


This is the first quite stable release since ... whenever - a large range of things have changed also on server side,  to name some:

* Support for basic features up to 1.11.2 (not all, not all combinations of effects, ...let's stay reasonable here, consider opening an issue at GitHub, if something is missing.).

* Some vehicles are controlled by the client, thus more checking.

* A range of configuration changes, you should probably regenerate the configuration, if you really update from an old build. Configuration changes are now alerted for per-configuration path (!).

* Preliminary block change and piston support (vertical for most), not perfect, but allow to stand where blocks had been, pass through - so possibly redstone driven blocks can be removed from the block flags and ignorepassable lists.

* Compatibility improvements (arrow-chairs, set-back handling, more fine grained data resetting with commands, other).

* Check refinements (horizontal speeding, other, check for extreme moves before passable).

* Countless fixes, internal changes. You do need to check for updates of plugins that depend on NCP.



Users of CompatNoCheatPlus have to update to the latest build as well, please wait for build 87+ to get approved:
