Item Blocker
by jacobxny
Item Blocker is a Fabric mod that stops players from picking up items they do not want, with a menu for listing which items to ignore.
What it does
Players list the items they want left on the ground, and those items are ignored when walked over. Item names can be typed as vanilla names or as IDs; the mod works with vanilla items by default, and modded items are entered using their ID in the usual namespace:name format. An item ID can be found by pressing F3 + H while hovering over an item in the inventory, which shows a tooltip with the minecraft:itemname style identifier.
The mod has two modes. In client side mode, blocked items are dropped immediately after pickup and stay dropped until they are removed from the menu. The other mode works differently: blocked items are never taken up in the first place, so they remain on the ground. That mode needs the mod installed on the server, and the environment is client and server, so both sides must run it. Fabric API is required, and the mod is published for 1.21 – 26.3 with snapshot builds included. The latest Fabric file is 1.5.5+26.2 for 26.2, released 2026-10-15, under the Creative Commons Attribution 4.0 license; the code is not open source.
Key features
Item blocking list
A menu lets the player choose specific items that should never be picked up while walking over them.
Two pickup modes
Client side mode drops blocked items right away, and the other mode keeps them from being picked up at all.
Vanilla and modded items
Vanilla items can be entered by name, and modded items by their ID, such as a research table item from another mod.
Item ID lookup
Holding F3 + H over an inventory item reveals its identifier in the tooltip, which helps when typing IDs.

How it compares
Player Blocker is a Fabric client mod for 26.1.2 – 26.2, with a client-side-only environment and All rights reserved licensing, so it is not open source. Attack-Blocker is a client-side-only Fabric mod for 1.20 – 1.21.11 under the MIT License, which makes it open source. Dimension Blocker is a server-side-only Fabric mod for 1.20.1 – 1.21.8, also under the MIT License and open source. Item Blocker covers the same goal of blocking unwanted items, but it adds a server-side option and runs as client and server, with no alternative sharing that exact design.
