MakkCH/minecraft_mcp ? reverse-engineered prompt

Build me a Minecraft helper that lets an AI agent control my Minecraft client while I can still watch and step in anytime.

I want two parts, a client mod that runs inside Minecraft and an agent side package that talks to it through MCP. The agent should be able to read game state, use screenshots, run scripts, explore, mine, fight, build, and debug its own behavior. I also want a simple takeover control so I can stop the automation with a command like /mcp stop and take back the player whenever I want.

Please make it work with local MCP clients like Cursor, Claude Code, and Claude Desktop, and keep the mod and the agent package installable and updateable separately. If you need to look up current docs or API details online, do that. Focus on making the whole thing actually usable in a real single player world, with a clear setup flow and sensible defaults.
