Mobs Are Gone is a mod that gives you full control over which entities are allowed to spawn in your world. No complex menus — just a simple JSON config file. Add any entity ID to config/mobsaregone-blacklist.json and that mob will never spawn again. Remove it from the list to allow it back. It works for any entity, including mobs from other mods.

Features:

Block any entity from spawning via a simple JSON config
Works with natural spawns, mob spawners, and spawn eggs
Supports modded entities — just add the mod's entity ID
Ships with a default blacklist containing all vanilla mobs pre-configured — just remove any mob you want to keep!
Villagers and Wandering Traders are excluded from the default blacklist and will spawn normally
Reload the blacklist in-game without restarting using /mobsaregone reload (requires OP)
When minecraft:ender_dragon is in the blacklist, the Ender Dragon boss bar is automatically hidden
Lightweight — no performance impact, no dependencies beyond NeoForge
Perfect for Cobblemon players who want a pure Pokémon experience without vanilla Minecraft mobs getting in the way!

How to use:

Install the mod
Start your server or world once to generate the config
Edit config/mobsaregone-blacklist.json
Add or remove entity IDs like "minecraft:creeper" or "minecraft:phantom"
Restart to apply changes — or run /mobsaregone reload to apply instantly without restarting!
