LootInjector

LootInjector is a Paper plugin + Fabric mod that gives you one place to control loot across your server. You can edit structure chests, direct loot tables, mob drops, villager trades, and enchanting outcomes, including datapack content. On Paper, it also has an in-game GUI so you can browse sources and tweak chances, add items, or block entries without digging through JSON by hand.
