Quick Shulker — Modern Port for Minecraft 26.3 (Fabric)

Quickly open a held shulker box with the press of a key!

No more placing a shulker box just to peek inside it. Hold a shulker box (or ender chest, crafting table, or stonecutter), press K, and it opens right in your hand — contents saved back to the item as you edit them. Perfect for quick inventory checks mid-adventure.

Now with a modern port for Minecraft 26.3 (Fabric), rebuilt for 26.3's data-component storage (DataComponents.CONTAINER), keymapping (KeyMappingHelper), and serverbound payload APIs.

What it does

• Press K (rebindable in Controls) while holding a shulker box, ender chest, crafting table, or stonecutter to open it in place
• Shulker contents live in the item's container data component and are saved back automatically as you edit them
• Works on servers too — opening is handled server-side via a custom packet

Modern port notes (26.3)

• Clean reimplementation for 26.3 APIs; drops the original's kyrptconfig/shulkerutils dependencies
• Right-click-to-open from the original was not ported (UseItemCallback changed substantially in 26.3) — the K keybind is the supported way to open
• Java 25 · Fabric Loader 0.20.1+ · Fabric API 0.165.0+26.3
• Built and verified in CI via GitHub Actions

Installation

1. Install Fabric Loader for Minecraft 26.3
