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 Example video of how NoCheatPlus blocks cheats (outdated plugin version).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

    Yeah, I'm aware of that. But I don't use WG, I use GriefPrevention.

    @mcly: Go

    What I would do is create a WorldGuard region right at the spawn point. Then for that specific region set the "send-chat" flag to deny.

    Yes i can run the /npc reload command. And yes, they dont change back after reloading, correct.

    @killerboss707: Go

    But the changed messages is inside the config and does not change back after reloading?

    You are using the word "does not save", which implies that the config changes after reloading or something like that, that's what is confusing.

    Can you run the command "ncp version" on the console now? Please post the output...

    Wait, what do you mean? The problem is that NCP does not save the text I put in, so instead of when people doing /pl and it says error please contact a adminastrator, the default stuff, I just want to change the messages, but they dont work. Everything else is fine.

    @killerboss707: Go

    Alright, i was just going there, because you stated "not saving what you put in", but i assume that was about the config display with using a paste (did you forget to set "language" to "YAML"?

    So the situation is that even the command-aliases you put in won't work.

    That's the moment when we really need the output of the "ncp version" command, can you just copy the text here? Maybe the feature can't work if NCP can not access something, are there any other errors in the logs during startup?

    well it shows in the config of what I added, just it dosent work IG
