MobsBeGone Mod is a Fabric utility mod that disables selected entity spawns in Minecraft 1.21.1.
If your modpack or survival world keeps generating mobs you do not want to deal with, mobsbegone mod solves that problem by letting you block those entities entirely through one config file. With over 2 million downloads on Modrinth, it has clear social proof from players who want a quieter, cleaner, or more controlled world setup.
Key Features of MobsBeGone Mod
- Config-driven blacklist — The mod reads
mobsbegone-blacklist.jsonfrom your config folder, so the setup stays straightforward. That matters if you want to remove a few problem mobs quickly without learning a larger spawn-management framework. - Entity ID based blocking — You can list entries such as
minecraft:creeperto fully disable those entities. This is useful when one specific mob disrupts a build, server theme, or modpack balance and you want a direct fix. - Fast lookup at startup — The blacklist is parsed at launch and stored in an O(1) lookup table. In practical terms, the mod appears to be designed for efficient checks instead of repeatedly scanning the config while the game is running.
- Catches multiple spawn sources — Spawn attempts from natural generation, commands, and structures are checked against the blacklist. That matters because blocked mobs should not sneak in through non-natural spawn paths and break your intended rules.
- Instantly discards blacklisted mobs — If an entity is on the list, it is removed before it visibly appears. For players, that keeps the world feeling consistent instead of showing unwanted mobs briefly popping in and vanishing.
- Works with modded entity IDs — The config can include mobs from vanilla Minecraft or other mods you have installed. That makes it especially useful in modded packs where one added creature feels out of place or too disruptive.
- Simple JSON format — The example config is just an array of entity IDs, with the only formatting caution being no trailing comma after the final entry. That keeps maintenance easy when you are adding or removing blocked mobs between test runs.

Frequently Asked Questions
Does MobsBeGone Mod work on Fabric?
Yes — Fabric Mod Loader is the required loader listed for this mod. The available download entry is for Minecraft 1.21.1 on Fabric.
Can MobsBeGone Mod block modded mobs too?
Yes — the config can include entity IDs from both vanilla Minecraft and other mods. You just need to add the correct entity identifier to the blacklist JSON file.
Will blacklisted mobs still appear for a moment before being removed?
No — the data states that blacklisted mobs are discarded and never visually spawned. The implementation is designed to mark those entities for removal on the next server tick to avoid issues.
Does this mod only affect natural spawning?
No — spawn attempts from natural spawning, commands, and structures are checked against the blacklist. That broader coverage is one of the main reasons to use it if you want strict mob removal.
Where do I configure the blacklist?
Use config/mobsbegone-blacklist.json. Add entity IDs in a JSON array, and make sure the final list entry does not have a trailing comma.
