AutoTag 1.21.1 Fabric Port (Unofficial)

An unofficial Minecraft 1.21.1 Fabric compatibility port of AutoTag by Apace and contributors. AutoTag automatically fills common tags for inter-mod compatibility, so modpacks can use shared tags instead of maintaining lists of items from every installed mod.

Included modules

• AutoTag API (autotag): the API for registering automatic tags.
• AutoTag Convention (autotag-convention): the upstream convention tags for items, blocks, and biomes.
• The API module is bundled inside the release JAR, so install the single JAR on both client and server when needed.

The port retains the upstream tag definitions, prevent-tag datapack support, and optional FabricShieldLib shield integration.

Compatibility

• Minecraft 1.21.1
• Fabric Loader 0.16.14 or newer
• Java 21 or newer
• Client and server
