Shulker Box Tooltip Mod (1.21.11, 1.20.6) – What's in My Shulker Box?

Shulker Box Tooltip is a utility mod that lets you preview the contents of shulker boxes and other containers directly from your inventory for Minecraft, available on Fabric, Forge, and NeoForge. Simply hover over any shulker box and press a key to instantly see what is stored inside without placing the block down.

Anyone who has played Minecraft past the early game knows the shulker box problem: you end up with dozens of color-coded boxes scattered across chests, and finding the right one turns into a tedious game of place-open-close-pick up-repeat. Shulker Box Tooltip solves this frustration elegantly by adding a hover preview directly in your inventory screen. With over 23 million downloads on Modrinth, this mod by MisterPeModder has become one of the most popular utility mods in the entire Minecraft modding ecosystem — and for good reason. It does one thing and does it exceptionally well.

Key Features of Shulker Box Tooltip

• Compact Preview Mode — Press Shift while hovering over a shulker box to see a condensed view of its contents. This is perfect for quickly scanning through multiple boxes in a chest without disrupting your workflow. The compact layout shows all stored items at a glance, making inventory management dramatically faster.
• Full Preview Mode — Press Alt+Shift to switch to a detailed full preview that displays every item stack in its correct slot position. This gives you an exact picture of how the shulker box is organized inside, which is especially useful when you have partially filled boxes and want to know exactly where free space is available.
• Support for All Container Types — The tooltip preview is not limited to shulker boxes alone. It also works with chests, barrels, furnaces, and most other containers obtained via creative mode or commands. Even modded containers from other mods are supported in most cases, making this a universal inventory preview tool.
• Color-Coded Preview Windows — The preview window border automatically matches the color of the shulker box you are hovering over. If you already use a color-coding system for your storage (blue for tools, red for redstone, etc.), the tooltip reinforces that organization visually, so you can identify the right box even faster.
• Loot Table Display — For map makers and technical players, the mod can display loot table information in the tooltip for items that have one assigned. This is an optional feature disabled by default, but it is invaluable when debugging data packs or inspecting loot containers in adventure maps.
• Extensive Configuration — Nearly every aspect of the mod can be customized through an in-game config menu accessible via Mod Menu. You can change keybindings, toggle color-coded previews, enable or disable loot table display, and adjust the preview appearance. The config file is stored at config/shulkerboxtooltip.json5 for manual editing.
• Optional Server-Side Installation — When installed on a server, the mod unlocks additional features such as ender chest preview. The server component is entirely optional — the mod works perfectly fine as a client-only installation, but adding it server-side enhances the experience for all connected players running the mod.

Frequently Asked Questions

Is Shulker Box Tooltip client-side only?

Yes — the mod works perfectly as a client-side only installation. You do not need it on the server to use the basic shulker box preview functionality. However, installing it on the server side unlocks bonus features like ender chest preview for all players running the mod.

Does Shulker Box Tooltip work with modded containers?

Yes, it supports most modded containers automatically. As of the latest update, any item using the standard minecraft:container component will generate a preview. This means the vast majority of modded storage blocks should work without any extra configuration needed.

Can I use Shulker Box Tooltip on multiplayer servers?

Yes — since it functions as a client-side mod, you can use it on any server without the server needing to install it. The mod reads container data that Minecraft already sends to your client, so it does not violate most server rules. Always check your specific server's mod policy to be safe.

How do I change the keybindings for the preview?

Open the config screen through Mod Menu on Fabric, or edit the shulkerboxtooltip.json5 file in your config folder. The default keys are Shift for compact preview and Alt+Shift for full preview, but both can be rebound to any key combination you prefer.

Is Shulker Box Tooltip compatible with Sodium and OptiFine?

Yes, Shulker Box Tooltip is generally compatible with performance mods like Sodium since it only modifies tooltip rendering and does not touch world rendering or chunk loading. OptiFine compatibility depends on your specific version combination, but most users report no conflicts. If you encounter issues, check that all mods are updated to the same Minecraft version.
