MobsBeGone
by EasyMochi
With MobsBeGone, a server owner lists entity IDs in a JSON file and those mobs stop spawning anywhere in the world.
What it does
The mod reads a file named mobsbegone-blacklist.json from the config folder. Each entry in that file is an entity ID, such as minecraft:creeper, and the listed types are disabled entirely. The blacklist is parsed once at startup and kept in a lookup table, so each spawn attempt is checked quickly.
When any mob tries to spawn, whether naturally, through a command or from a structure, the mod checks it against the blacklist. A blacklisted mob is marked for removal on the next server tick, so it never remains in the world. Entries can come from the base game or from any other installed mod.
It runs on the server alone, so players need nothing extra to join. It requires Fabric API and is released under the MIT License, with the source code and an issue tracker public. Files exist for Minecraft 1.21.1, with 0.0.9 as the latest, published on 2026-08-03.
Key features
JSON blacklist
Entity IDs go into a single JSON file, so the list can be edited without touching any code.
Spawn-time checks
Every spawn attempt is compared with the blacklist, covering natural spawns, commands and structures.
Removal on the next tick
Blacklisted mobs are marked for removal on the next server tick, which avoids unsafe edits to the world.
Base game and modded entities
Any entity from the base game or from another installed mod can be added to the list.

Use cases
Quieter survival servers
A server owner removes mobs that clutter a survival world, such as creepers near player bases.
Mob-free builds
Creative and build servers can list every hostile type to keep the world free of mobs.
Who it’s for: Server owners who want to disable specific mobs without learning a larger configuration system. The mod is a server-side tool, so it fits servers more than single-player worlds.
