Understanding Why DataPack Anvil Mod Is Required

What DataPack Anvil Does in Your Modpack

DataPack Anvil is a library mod that runs behind the scenes to facilitate datapack-driven mods. Instead of hardcoding features directly into game files, dependent mods use datapacks to store and manage their custom data. DataPack Anvil provides the core data managers that allow these mods to register custom data types, dedicated datapack events, custom tags, and block predicates.

Because it is purely an underlying framework, it does not add standalone items, blocks, or visible mechanics on its own. You will typically find it in your mod list because another mod installed in your game requires it to function.

Checking If You Need to Keep It

• Do not delete the mod file: If a content mod depends on DataPack Anvil, removing it from your mods folder will cause your game to crash on startup or display a missing dependency warning.
• Verify dependencies: Only remove DataPack Anvil if you have already uninstalled all mods that rely on custom datapack data management.
