Creator Tip

Always double-check your **Min Engine Version**. Setting it too high might prevent players on older versions of Minecraft from using your pack.

The Professional
Bedrock Pack Studio

Building Minecraft Bedrock packs shouldn't be about fighting JSON errors. MC Toolbox provides a high-fidelity environment to generate valid, professional-grade manifest files for all game versions.

Universal Compatibility

Our generator follows the official Minecraft Bedrock Edition specifications exactly. We handle UUID v4 generation, semantic versioning, and specific module types automatically, ensuring your Resource Packs, Behavior Packs, and Skin Packs work flawlessly.

Automated Validation

Stop manually looking up module types like `resources` vs `data`. MC Toolbox intelligently assigns the correct type based on your pack selection, preventing "broken pack" errors in-game.

Frequently Asked Questions

A manifest.json file is the 'ID card' of your Bedrock pack. It tells Minecraft the name, description, version, and unique identifiers (UUIDs) of your creation. Without this file, the game won't recognize your folder as a pack.

Bedrock Edition uses one UUID for the 'Header' (the pack itself) and one for each 'Module' (the content). These must be unique so that Minecraft can distinguish between different versions and instances of your pack even if the name is the same.

Download or copy the code into a file named 'manifest.json' at the root of your pack folder. Make sure the extension is exactly '.json' and not '.txt'!

This tells Minecraft the minimum version of the game required to run your pack. For example, if you use features from 1.21, set this to 1.21.0 to ensure player compatibility.

World Templates are used when creating maps that players can use to generate new worlds. Choosing 'World Template' correctly sets the module type in your manifest so Minecraft treats it as a map template.

Pack Metadata

Minecraft Manifest and Pack Metadata Generator

The manifest generator creates Bedrock manifest.json files and Java pack.mcmeta metadata so resource packs start with valid IDs, names, descriptions, and version fields.

What this tool does

Pack metadata is small but easy to break. This tool helps generate UUIDs, module entries, format versions, and descriptions so you can focus on textures, sounds, models, or behavior files.

When to use it

Use it when starting a new Bedrock resource pack, behavior pack, or Java pack. If you are editing an existing pack, keep backups before replacing metadata files.

Quick questions

Why are UUIDs important?

Bedrock uses UUIDs to identify packs and modules. Duplicated UUIDs can cause packs to conflict.

Can this build a whole pack?

It creates metadata. You still add textures, models, sounds, or behavior files separately.

What do you think about this tool?

If something feels wrong, a Minecraft version is missing, the wording is confusing, or you have a better workflow idea, send it over. Real player feedback is how these tools get sharper.
