Install a datapack in the active world’s datapacks folder. Datapacks change Java Edition gameplay through functions, recipes, loot tables, advancements, and other data-driven features.

​
Install a datapack

1

Check compatibility

Confirm that the datapack supports the server’s Minecraft version and read its installation notes. Create a backup before adding world-generation or gameplay changes.
2

Find the active world

Stop the server and check level-name in server.properties. Open that world folder, then open datapacks.
3

Upload the datapack

Upload the datapack .zip or its extracted folder. Do not add an extra wrapper folder: the datapack’s pack.mcmeta must be at the top level of the ZIP or folder.
4

Start and verify

Start the server and run this in the game panel console:
Check the console for an incompatible pack format or validation error.

​
Update or remove a datapack

Stop the server before replacing or removing the datapack. Back up the world first, especially when the pack creates dimensions, structures, scoreboards, or persistent data. Start the server and use datapack list again to confirm the result.
Removing a datapack does not necessarily undo changes it already made to the world. Follow the datapack author’s uninstall instructions when provided.
