Item Manager

Take full control of items on your Minecraft server. Ban, restrict, or mark items as illegal — with automatic enforcement, JEI integration, dimension support and custom messages.

Description

Item Manager is a server-side moderation mod that allows administrators to control which items players can have, craft, or carry on their server. Whether you're running a survival SMP, an RPG server, or a competitive environment, Item Manager gives you the tools to enforce item rules automatically — no plugins, no command spam, no manual enforcement.

Simply add an item to a category and the mod does the rest.

How It Works

Item Manager has 3 enforcement categories, each with a different level of restriction:

🔴 BANNED

The most severe restriction. Banned items are completely forbidden on the server.

• ✖ Automatically removed from the player's inventory every second
• ✖ Automatically removed from any chest or container when a player opens it
• ⚠ Players receive a warning message when an item is removed
• 🏷️ Red tooltip warning shown on the item
• 💬 Supports fully custom messages per item with color codes
• 🌍 Can be restricted to specific dimensions only

🟠 ILLEGAL

A softer restriction. Illegal items can exist in the inventory but cannot be actively used.

• ↩ Automatically moved out of the hotbar (slots 0–8)
• ↩ Automatically removed from the offhand slot
• ↩ Automatically unequipped from all armor slots (helmet, chestplate, leggings, boots)
• The item stays in the main inventory — it is not destroyed
• 🏷️ Orange tooltip warning shown on the item
• 💬 Supports fully custom messages per item with color codes
• 🌍 Can be restricted to specific dimensions only

🟡 RESTRICTED

The lightest restriction. Restricted items can be owned but cannot be crafted.

• ✖ Crafting recipes are blocked — the result is cancelled automatically
• ✖ Recipes are removed directly from the server on startup
• ✖ Recipes are hidden in JEI (Just Enough Items)
• 🏷️ Yellow tooltip warning shown on the item
• 💬 Supports fully custom messages per item with color codes
• 🌍 Can be restricted to specific dimensions only

Dimension Support

Every item can be restricted globally or only in specific dimensions — including modded dimensions.

# Global restriction (all dimensions)
/itemmanager add banned minecraft:tnt

# Only in the Nether
/itemmanager add banned minecraft:tnt --dim minecraft:the_nether

# Only in the End
/itemmanager add illegal minecraft:elytra --dim minecraft:the_end

# Modded dimension
/itemmanager add banned botania:mana_sword --dim botania:alfheim

Custom Messages

Every item can have a fully custom tooltip message in any language, with full Minecraft color code support using &.

/itemmanager add banned minecraft:tnt|&8[&c&lBANNED&8] &c▪ &fThis item is forbidden.
/itemmanager add illegal minecraft:diamond_sword|&6No puedes usar esto aquí.
/itemmanager add restricted minecraft:elytra|&eItem restringido en este servidor.

# With dimension
/itemmanager add banned minecraft:tnt|&cNo TNT en el Nether --dim minecraft:the_nether

If no custom message is set, a default bilingual message (Spanish/English) is shown.

Live Config Sync

No server restart needed. Changes apply instantly:

• Config syncs to all players automatically after every command
• Config syncs to a player when they log in
• /itemmanager reload forces a manual sync to all players

Commands

All commands require OP level 2 or higher. All have Tab auto-complete.

Quick Start

1. Install the mod — Place itemmanager-1.2.0.jar in your server's mods/ folder. Works on Forge and Mohist servers. For JEI recipe hiding and tooltips, clients also need the mod installed.

2. Start the server — Config file is created at world/serverconfig/itemmanager-server.toml

3. Add items via commands:

/itemmanager add banned minecraft:tnt|&cForbidden on this server
/itemmanager add illegal minecraft:diamond_helmet|&6Cannot be equipped
/itemmanager add restricted minecraft:elytra|&eNot craftable here

4. Edit manually (optional):

[items]
    banned = ["minecraft:tnt", "minecraft:tnt@minecraft:the_nether"]
    banned_messages = ["minecraft:tnt|&cForbidden!", "minecraft:tnt@minecraft:the_nether|&cNo TNT here"]
    illegal = ["minecraft:diamond_sword"]
    illegal_messages = ["minecraft:diamond_sword|&6Cannot use this"]
    restricted = ["minecraft:elytra"]
    restricted_messages = []
