Why we included this project

Most LLM demos stop at text, but this one puts a model inside a live Minecraft world. It's an MCP server that lets Claude or any other MCP-compatible client drive a bot through natural-language commands: move around, dig and place blocks, manage inventory, smelt items, and read in-game chat. Setup is straightforward: open a single-player world to LAN, point the server at localhost, and the bot joins your game. Watching an agent build structures is fun, but the project earns its keep as a testbed: you can watch how an LLM plans multi-step actions, whether its tool calls hold up, and how it reacts when the game state doesn't match what it expected. It's written in TypeScript on top of Mineflayer, so teams poking at agentic behavior or tool-use reliability get a small, hackable codebase to experiment with.
