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 Example video of how NoCheatPlus blocks cheats (outdated plugin version).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

    My internet connection is slower today. In Brazil the internet speed varies depending on the day. Afterward I test and send what appears on nocheatplus.log.

    @szebi1999: Go

    Can you be more specific on what conflicts there are? We can not test all plugins out there on our own, for compatibility issues we need some input on what does conflict, what features of the other plugin are blocked and what checks from NCP are involved.

    @ThaSourceGaming: Go

    Same thing. It is limited by NCP but not fully blocked. Fully blocking would mean that false positives also lead to fully excluding legit players from combat. So there is no badge "kill aura", but several fight checks combine to reduce it to give legit players a chance in fighting. We are planning to improve the fighting checks as one of the next things we do, reducing false positives to be able to go harder on cheaters.


    Latest Release (1.7.2/.4/.5, approved): NoCheatPlus 3.10.9-RC-sMD5NET-b673 (Development builds, + MC 1.7.5: Jenkins)

    @Robson112011: Go

    Thanks, this looks like survivalfly false positives - do you happen to have "ordinary" log messages like in-game alerts or console or nocheatplus.log entries with the survivalfly failures of such a jump? Specifically if you have the [tags] shown in the flyshort and/or flylong messages in the strings section. This could help identifying what part of survivalfly triggers here.

    @ThaSourceGaming: Go

    We have several measures taken that effects of forcefield hacks get reduced by a good bit.

    Tested now falling to 41 blocks high, I died and in the chat message appeared: Robson112011 fell from a high place. I died on touching water.

    Before: 01.03 20:20:53 [Server] INFO NCP: [20:17:41] blockinteract.visible VL 1 (n1a1m1) 01.03 20:20:53 [Server] INFO NCP: [20:18:54] moving.survivalfly VL 388 (n4a97m160) 01.03 20:20:53 [Server] INFO NCP: Displaying Robson112011's violations...

    After: 01.03 20:21:48 [Server] INFO NCP: [20:17:41] blockinteract.visible VL 1 (n1a1m1) 01.03 20:21:48 [Server] INFO NCP: [20:21:35] moving.survivalfly VL 458 (n7a65m160) 01.03 20:21:48 [Server] INFO NCP: Displaying Robson112011's violations...

    My console show messages in upward.

    Sometimes does not die but receive damage and back into place where it started the jump.

    If need versions, my /ncp version: 01.03 20:24:59 [Server] INFO Hooks: mcMMO(cncp) 2.3 01.03 20:24:59 [Server] INFO MCAccess: 1.5.2 / CB2763 01.03 20:24:59 [Server] INFO Plugin: 3.10.8-RC-sMD5NET-b664 01.03 20:24:59 [Server] INFO NoCheatPlus 01.03 20:24:59 [Server] INFO git-Bukkit-1.5.2-R1.0-b2788jnks (MC: 1.5.2) 01.03 20:24:59 [Server] INFO Server 01.03 20:24:59 [Server] INFO Version information --

    @X00LA: Go

    Build 670 should correct this.

    @Robson112011: Go

    Do the players die on touching the water or just somewhere in air?

    Can you show violation messages of players death during falling? I am most interested in the ones stating the distance and tags, if you have not changed the configuration to hide those, but any alerts/log messages that can be tracked to such a case would be interesting.
