- For
- Minecraft server owners experimenting with AI builders
- Worth noticing
- The planner returns five JSON fields; dimensions and materials are constrained before local code issues bounded `/fill` commands.
Field notes
The starter connects to a local Minecraft Java server through Mineflayer, loads saved state, then repeats a build cycle on a configurable interval. Its optional planner returns bounded building details; the local program limits materials to an allowlist and constructs the server commands itself. Without an AI key, built-in presets can test the connection and loop.
