Mob Control
by ohayden
Mob Control is a rule-based system that lets modpack designers decide which mobs spawn, where, when and how they behave, all set in one human-readable config file.
What it does
Rules are written in mobcontrol.toml and processed from top to bottom. The first rule that matches a mob decides whether it may spawn. Rules can change many properties of a mob, such as experience reward, health and damage, and they can attach custom AI to any mob.
Spawn conditions can be limited to specific dimensions, biomes, structures, days, weather and times of the day. Spawn rates can be raised or spawning blocked outright. Both the server and every player's client run the mod, so each side needs it installed.
Files are published for Fabric, Forge and NeoForge, with builds covering 1.20.1 – 26.1.2. The latest file is 2.0.1-beta-2 for 26.1.2, released 2026-07-17 on the beta channel. The mod is licensed as All rights reserved and is not open source. Configuration options are documented on the project's wiki.
Key features

Dimension, biome and structure limits
A rule can restrict a mob to chosen dimensions, biomes or structures.
Day, weather and time rules
Mobs can be set to spawn only on certain days, in certain weather or at certain times of the day.

Health, damage, experience and custom AI behaviors can be assigned to any mob through rules.

How it compares
Only Zombies Spawn is server-side only, so players join without installing it, and it is open source under the MIT License with files for 1.18.2 – 26.2. LimitedSpawners is open source under the MIT License, runs on client and server, and covers 1.19 – 1.20.2, a narrower range than Mob Control. Easy Mob Spawn Control needs the server, with the client optional, and is licensed All rights reserved.
