Introduction

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 Example video of how NoCheatPlus blocks cheats (outdated plugin version).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

ProtocolLib

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

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.)

    NCP needs to update to support 1.9 features. We haven't seen an update since late January. For now, just disable whatever check goes off when people use elytra.

    I was testing on my own server, and people can eat while running and not lose speed, Can that be fixed? @asofold

    @asofold: Go

    In simple terms, a /ncp tell 'staff' [message here] (or another placeholder instead of staff for all users with the permission node 'nocheatplus.notify') command which would be used to send a message to all users with the correct permission node, mentioned above. I am already well aware that strings can have color codes incorporated into them. I would like to use an external plugin to check for select conditions (Player ping and tps) prior to notifying - I would have to set up multiple commands and strings for each one, but I feel that it would generally be worth my own time setting up if the additional command is implemented. If it's too much of a fuss to add, don't worry about it.

    @MarkElf2204: Go

    I don't fully understand what you want there, though... if an external plugin would have a command to notify via NCP, placeholders wouldn't work for sure as they're bound to a context. So the idea is to .... what was the idea? A command with color replacement to log somewhere wouldn't be a problem.

    @donnie8986: Go

    I assume you're running an outdated version of NCP - please refer to the link to Jenkins (above), there also is a 'notable builds' page linked, which gives a quick overview by Minecraft version. If in doubt please just post the oputput of the 'ncp version' command.

    Hello,

    Is there a solution to the slab-glitch, doors, and path issue? My players complain that they cannot walk through doors without being glitched along with not being able to walk on half slabs and the new 1.9 paths. Thank you in advance for the help.

    @asofold: Go

    I would definitely like for it to be implemented in order to use NCP with external plugins as it seems quite complex otherwise since placeholders such as [player] don't function across a second plugin for notifying although NCP runs the command, through console for the "cmd:(command here)" action.

    @MasterClaus: Go

    If you are running 1.9, I would recommend running NTAC (https://www.spigotmc.org/resources/22746/) as well since it will have NCP drag players down instead of teleporting them to their original location and comes with a handful of other benefit-able checks that are yet to be implemented to NCP directly.

    I'm having a problem with anti survival fly For example a player playing a parkour map, when they jump miss, turn on flight hack while floating and NCP will revert them to the previuos block they were standing instead of falling down. Any sollution?
