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 Example video of how NoCheatPlus blocks cheats (outdated plugin version).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

    i didnt get to run the latest dev vesions of ncp and compatncp long enough to see possible crashes, the players wanted them off the server because their skills fail a lot.

    @publicg: Go

    • So it does not crash with latest builds? [Pushed 3.13.1 as a bug fix beta release, waiting for approval here on dbo.]
    • For SkillAPI likely nothing changed, unless they updated to use the API of NCP. I will have a look some time soon, what i can do for a fast thing.

    @publicg: Go

    Please ensure to test with the latest release (currently build 878).

    @Tintin159: Go

    Complex topic: Ticket 364

    Likely we will make an attempt some time soon.

    @Schneidertm: Go

    The logging configuration isn't 100% stringent, as it's been focused on the violation alerts in the past, while status messages are always logged to the file. So you can't fully disable the file - or do violation notifications still show up in there? That would be a (newly introduced) bug then. Fully disabling is possible with setting an invalid file name ("" might do it). If you ever intend to being able to do on the fly debug logging, you might want to keep the file enabled though.
