Swarm Foundry

Let a small plan take shape one paid block at a time. Swarm Foundry makes construction visible, giving you a way to place repeated structures without an unlimited building machine.

Watch a small building plan take shape

Find clear space, carry oak planks and start the supplied arch. Three small visual workers trace the construction as paid blocks appear from bottom to top.

It is useful for repeating a simple shape while you work on the surrounding build. Sneak-use cancels unfinished work; blocks already placed stay where they are. The editor also offers a short wall or four-step stair.

Craft it

• Swarm Foundry: 1 × diamond, 2 × copper ingot, 1 × amethyst shard, 1 × stick.

Open the editable project below and choose Crafting Path to check each recipe’s exact arrangement.

Before you try it

• Plans are limited to a small arch, short wall, or four-step stair. Workers do not design arbitrary buildings.
• Existing terrain is not replaced. Missing materials do not become free blocks.
• Cancellation stops future work; it does not dismantle what you already paid to build.

Each activation costs one amethyst shard in Survival, with a three-second cooldown. Creative use is free.

Download the beta MCADDON from Files for Minecraft Bedrock 26.52. Import it and enable both the behavior and resource packs in a separate world. Start with a copy of a world you care about.

Checked on Windows in a separate test world. Other devices and live multiplayer have not been verified.

Make it yours

Choose Short wall and set Worker count to one to see the order clearly. Change Bottom to top to Near to far for a different sequence.

Open Swarm Foundry in the constructor to change the settings and build your own version. Save its editable project if you want to keep working later.
