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 Example video of how NoCheatPlus blocks cheats (outdated plugin version).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

    On my server, every time someone stands on a slab, they glitch. Is there a way to stop this?

    There needs to be a way to make pillaring up/towering up, not TP you back down to the ground. This needs to be fixed.

    if you suspect someone hacking and you clear there flag list and see they were flagged again for the critical/reach how accurate is it to know they're in fact hacking?

    some people who pvp all day dont even get flagged for critical's or reach

    NoCheatPlus: version: 3.15.0-SNAPSHOT-sMD5NET-b1020

    GriefPrevention: version: 14.3

    Spigot: 1.10.2 Actual blocks Blocks sendt to the client by GriefPrevention

    If a player walks on top of the gold/glowstone and those blocks are slabs or any half blocks NPC will spam staff about flyhack. I don't know if this should be considered a bug in GriefPrevention, NPC or non of them.

    I just wanted you to be informed about the problem.
