Score: 7.0/10 (Innovation: 7, Technical: 8, Documentation: 8, Utility: 5)

Herobrine is a system for controlling Minecraft agents via natural language, using a two-tier model architecture: a planner LLM interprets user instructions into typed tasks, and a JEV model selects concrete actions each second for Mineflayer to execute. It integrates as an MCP server for Claude Code/Codex or as a CLI, enabling agents with dynamic personas, goals, and in-game chat interaction.

Target audience: AI researchers, game developers, Minecraft enthusiasts, and developers interested in LLM-based agents
