Nemobot brings local LLMs to Minecraft

Nemobot is a lightweight open-source Minecraft agent that connects Mineflayer, a small Python/Flask bridge, and NVIDIA's Nemotron 9B running on vLLM so players can issue natural-language commands like following, fighting, digging, and guarding. The notable part is the simplicity: it uses prompt-constrained structured output plus regex parsing instead of fine-tuning, cloud APIs, or heavy agent frameworks.

// ANALYSIS

This is the kind of small-scale agent project developers actually learn from: tight action space, local inference, and a control loop simple enough to debug end to end.

–The stack is pragmatic rather than flashy, using Mineflayer for game actions and an OpenAI-compatible vLLM endpoint for model serving
–The structured `[action] COMMAND("arg")` pattern shows how far prompt engineering can go before you need full tool-calling infrastructure
–Running on a single RTX 5090 with no cloud dependency makes it a useful template for hobbyist and local-agent experimentation
–Its limits are obvious—fixed commands, no visual perception, short memory—but those constraints are also why the whole system stays understandable
