What is minecraft-ai-python CLAUDE.md?

Project instructions for Minecraft AI-Python, a framework for controlling Minecraft characters with Python and language models. The project connects Python code to Minecraft through JavaScript and the mineflayer library.

Use them when developing or running the Minecraft bots, managing Python packages with uv, compiling the project, or running its unit and web-view tests.

They explain the project's moving parts and required development setup, reducing errors caused by using the wrong runtime, package manager, or startup process.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade C, and why

minecraft-ai-python CLAUDE.md scanned grade C with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Minecraft AI-Python: Developer Guide

This document summarizes the key requirements and setup instructions for the Minecraft AI-Python project, with a focus on using uv for Python package management.

Project Overview

Minecraft AI-Python is a modular framework for building AI Characters (AICs) in Minecraft. It uses Python to control Minecraft bots via a JavaScript bridge (JSPyBridge/mineflayer), enabling LLM-driven agents to interact with the game world.

Key Components:

Python 3.9+ - Main runtime for AI agent logic
Node.js - Runs mineflayer for Minecraft protocol communication
JSPyBridge - Python-JavaScript interop package (v1.2.6+)
LLM Provider - OpenAI, Anthropic, Ollama, or compatible API

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
