What is a component?
A component is simply a part of MobManager. Every component can be enabled/disabled individually from config.yml
To do
  • Add Protection component to MobManager (Protect the world from things like explosions or Endermen picking up blocks)
Note: The above are just ideas, not all of them may happen (If you particularly want one done let me know)
Note: Ordered by importance to me (Higher == More important) (Your needs are important to me :D)


  • /mm help - Prints information about all the available commands
  • /mm count - Prints mob counts and limits for each world which MobManager is active. Also prints totals for the server

  • /mm butcher - Removes all mobs (Except villagers) from worlds enabled in MobManager
  • /mm butcher <MobTypes> - Removes the given mob types from all worlds enabled in MobManager

Note: the count command prints single letters to represent the different categories of mobs.
M = Monster, A = Animal, W = Water Animal (Squid), Am = Ambient Mob (Bats), V = Villagers

As of v2.2 MobManagers configuration files consists of three parts
  • config.yml - Contains settings to enable/disable MobManager components
  • Global configs - Contains global configs for each component, located in MobManager/<component>.yml
  • World Configs - Contains settings for each component for each world located in MobManager/worlds/<worldname>/<component>.yml

Every config file contains a header block explaining every setting.

When you first install MobManager world and global configs are auto-magically generated.
By default only MobManagers Limiter is enabled, configs for abilities are generated if the component is enabled
The defaults for the limiter are pretty conservative. So you may wish to increase the limits.
If you need help with the config feel free to PM me and I can make one for you :)
Auto-Update Checker
Mobmanager includes a update checker/downloader. It uses this project page to check for new approved builds. The /mm version command can be used to check if a new version is available on bukkit dev.
The update checker is enabled by default and can be disabled in config.yml by setting EnableVersionCheck to false
The update downloader is disabled by default can be enabled in config.yml by setting EnableAutoUpdater to true

MobManager utilises Hidendra's plugin metrics system, which means that the following information is collected and sent to
  • A unique identifier
  • The server's version of Java
  • Whether the server is in offline or online mode
  • The plugin's version
  • The server's version
  • The OS version/name and architecture
  • The core count for the CPU
  • The number of players online
  • The Metrics version
  • MobManager components enabled
All information is publicly available and can be viewed at

Opting out of this service can be done by editing plugins/Plugin Metrics/config.yml and changing opt-out to true
Public Test Server
Public test server has been shut down, will try get a new one in the future
Feel free to join and have a look for yourself what MobManager does. Server has two worlds one with MobManager enabled, the other with it disabled. You are allowed to use /time to set the world to night, so monsters spawn on the surface. This server uses default settings for all configs.
Note: After joining, type /warp dev
Note: The test server only has the limiter component enabled

Please, if you have and questions or feature requests, do not hesitate to ask

    Can you Limit Monsters per User-Groups? WIth 1 Player you for example get 10 Monsters.

    With 2 Players you would get 20.

    For 5 you would get 50 and you got too many and get overrun.

    Can you Limit it so with more Players in one "Chunk-Region" the Monsters Count gets more, but by percentage less?

    So for 5 you would get 25 or something like that?

    Hi and thank you for this plugin.

    I was wondering if I could set spawn settings for mounted mobs (like a zombie riding a zombie horse, or an armoured skeleton riding a spider... I can't find any mounted combination in the Entitylist of bukkit.

    If it's possible, how would you write it ?

    Also, how would you set wolves to always spawn angry in a specific biome ? Like peaceful "dogs" in plains where villages are and always angry wolves in mountains and forests

    @GuKoMC: Go

    Maybe try to disable the MM Spawner. I did. It seemed to be ignoring the limit and just popping up mobs in front of me until there was a herd surrounding me. Lol

    So just wanted to pop in and say the plugin seems to work well on 1.9.2, the only issue is

    SunProofRate: 1.0

    Will be replaced by

    VillagerRate: 0.0
    SunProofRate: 0.0

    Randomly, and I don't know why. Basically, I'll get 3 backups, and all replaced with that string. Even if I just replace the sunproofrate on the newly added strings, it'll back them up and replace.

    Another issue now is Custom Mob Names are now seen very far until the the chunk is about to unload. Also seen through the ground.

    Spigot 1.9. latest Version / MobManager 3.0.5-2 dev

    It seem not be solved until now:
    MobManager seems to be despawning Mobs, that have been NameTag-ed. Why's that?

    Same Problem ... it despawns NameTagNamed Animals with MobManager, and it despawns not without it.
    In both cases the same way to Name-Tag the animal.

    In this case it's the Endermite for an Enderfarm, created with an enderperl, renamed by NameTag... and after 2 Minutes it despawns only with this plugin. Without MobManager, it stays endless.

    Has anyone determined if you can block horses using this? I can't seem to make it work even when it seems to recognize the entity names. They still spawn at the "normal" accelerated rate.
