LLM agents that play Minecraft

One command clones SimulateCraft. Install Git + Node.js 18+ first, then add OpenRouter, 9Router, or your own API in .env.

Prefer OpenRouter, 9Router, or your own API. Groq works for a quick try but hits rate limits fast.

  • OpenRouter — set OPENROUTER_API_KEY in .env
  • 9Router — set OPENAI_BASE_URL, OPENAI_API_KEY, and SIMULATECRAFT_MODEL
  • Own API — any OpenAI-compatible endpoint via OPENAI_BASE_URL
