MobSpawnController
by taisuiyileba
MobSpawnController gives server owners a command-driven control layer over where and how mobs appear, including natural, spawner and breeding spawns.
What it does
Server owners can switch mob spawning on or off per spawn type, such as natural spawning, spawner spawning, breeding and event spawns. Natural spawning can be turned off while spawner-based spawning stays active, or the other way round. The rules are checked before a mob enters the world, so a blocked spawn never appears and then gets removed. Mobs registered as ordinary entity types are covered, so modded mobs fall under the same settings.
Natural spawns can also be limited by conditions in the style of InControl. A rule can name the biomes, light levels, times or other conditions in which a mob may appear. A condition left blank is treated as unrestricted, so a rule only narrows what it names. With Serene Seasons installed, the mod adds an optional integration that restricts natural spawns to specific sub-seasons.
The mod is a lightweight server-side mod for Fabric, Forge and NeoForge. Settings are changed with commands or an in-game GUI. The server needs the mod, while players may add it without losing any function. Builds exist for 1.20.1 and 1.21.1, and the latest file for both loaders is 1.3.0, released 2026-10-03. The code is not open source; a source repository is public, under All rights reserved.
Key features
Per spawn type toggles
Spawning can be enabled or disabled for each spawn type, including natural, spawner, breeding and event spawns.
Separate natural and spawner control
Natural spawning can be stopped while spawner-based spawning continues, or the reverse.
Condition rules for natural spawns
Natural spawns can be restricted with InControl-style conditions, and unset conditions do not limit a rule.
Commands and in-game GUI
Rules are adjusted through commands or an in-game screen, without editing configuration files by hand.
