Container Blocker

A lightweight Minecraft Fabric mod that prevents configured items from being placed into containers. By default, it blocks the Ender Dragon Egg, but can be configured to block any item.

Features

  • Configurable blocked items: Customize which items cannot enter containers via config/blocked_items.json
  • Blocks manual placement: Prevents players from clicking blocked items into container slots (chests, barrels, hoppers, etc.)
  • Blocks shift-clicking: Prevents players from shift-clicking blocked items from their inventory into containers
  • Blocks hoppers: Prevents hoppers from transferring blocked items between containers
  • Works with all containers: Applies to all container types including chests, barrels, shulker boxes, hoppers, and modded containers
  • Player inventory allowed: Blocked items can still be moved within the player's own inventory and hotbar

Configuration

The mod creates a config/blocked_items.json file on first run. You can edit this file to customize which items are blocked:

{
  "blockedItems": [
    "minecraft:dragon_egg"
  ]
}

How it works

The mod uses Mixins to intercept item transfer methods
