MobsFilter

is a lightweight mod that lets you blacklist entities from spawning entirely. Keep your world/server clear of unwanted mobs with a fast, easy-to-use configuration and live in-game commands.

Features

Entity Blacklisting

• Total Control - Blacklist specific vanilla or modded entities from spawning entirely.
• Fast & Safe Cleanup - Entities are checked against a fast lookup table during spawn. Blacklisted entities are discarded immediately and cleaned up safely on the next server tick.
• Wide Compatibility - Works with standard vanilla namespaces (e.g., minecraft:creeper) and modded entities (e.g., anothermod:some_entity).

Commands & Configuration (OP Required)

• /mobsfilter add <entity> - Adds the entity to the blacklist and reloads it immediately. Supports clean autocomplete (with or without the minecraft: namespace).
• /mobsfilter remove <entity> - Removes the entity from the blacklist and reloads it instantly.
• /mobsfilter list - Shows all current blacklist entries loaded from the config.
• JSON Config - All changes are automatically saved and read from config/mobsfilter-blacklist.json.

Config Example:

[
  "minecraft:creeper",
  "minecraft:enderman",
  "anothermod:some_entity"
]

Dependencies:

• Fabric API (required)

Server-Side - Works perfectly as a server-side mod. Your players do not need to download or install this mod on their clients for the entity filtering to work!
