Silk Touch Harvest

A lightweight, config-driven Fabric mod for Minecraft 1.21.1 that lets you harvest blocks that normally drop nothing in vanilla — spawners, trial spawners, vaults, cake, and more — using Silk Touch.

Key features

• Harvest spawners with Silk Touch (drops an empty spawner, no XP).
• Extract the spawn egg from a spawner by right-clicking it with a configurable item (default: stick). The spawner is emptied and the matching egg goes straight into your inventory.
• Fully configurable — add or remove any block by ID, change the extraction item, and toggle each behavior in a simple config file.
• Works on server and client. Requires Fabric API.

Default blocks

Spawner, Trial Spawner, Vault, Budding Amethyst, Cake, Turtle Egg, Sniffer Egg, Frogspawn, Reinforced Deepslate — all editable in the config.
