Minecraft: Build & Explore Boundless Worlds

Key Features of Minecraft: Build & Explore Boundless Worlds?

Autonomous Navigation

The bot uses advanced pathfinding to move through complex terrains. My favorite feature is its ability to dynamically avoid obstacles while following user-defined paths.

Intelligent Construction

By interpreting natural language commands, the bot can construct buildings, redstone systems, and even complex farms. Try saying "Build a 10x10 obsidian tower with torches" for instant results!

Real-Time Interaction

The bot maintains continuous communication with your AI model, allowing for adaptive gameplay. This makes it perfect for collaborative projects with friends or educational scenarios.

Use Cases of Minecraft: Build & Explore Boundless Worlds?

Creative Design Studio

Architects and designers can rapidly prototype ideas by voice or text. The bot handles repetitive tasks like stair construction while you focus on creativity.

FAQ from Minecraft: Build & Explore Boundless Worlds?

Q: Does this require a dedicated server?

No, it works on single-player and most public servers but requires basic permissions. Always check server rules before deploying bots.

Q: Can I use other AI models besides Claude?

Absolutely! The MCP protocol is model-agnostic. I've had success integrating with OpenAI's GPT series by modifying the API endpoint in the config file.

Q: What's the best way to debug errors?

Start by checking the debug.log file - it's saved in your Minecraft mods folder. For complex issues, try simplifying your commands and gradually add complexity.

Minecraft MCP Server

A Minecraft bot powered by large language models and Mineflayer API. This bot uses the Model Context Protocol (MCP) to enable Claude and other supported models to control a Minecraft character.

Prerequisites

• Node.js
• A running Minecraft game
• Claude Desktop (the setup below was tested with Minecraft 1.21.4 Java Edition included in Microsoft Game Pass)

Getting started

This bot is designed to be used with Claude Desktop through the Model Context Protocol (MCP).

Run Minecraft

Create a singleplayer world and open it to LAN (ESC -> Open to LAN). Bot will try to connect using port 25565 and hostname localhost. These parameters could be configured in claude_desktop_config.json on a next step.

MCP Configuration

Make sure that Claude Desktop is installed. Open File -> Settings -> Developer -> Edit Config. It should open installation directory. Find file with a name claude_desktop_config.json and insert the following code:

{
  "mcpServers": {
    "minecraft": {
      "command": "npx",
      "args": [
        "-y",
        "github:yuniko-software/minecraft-mcp-server",
        "--host",
        "localhost",
        "--port",
        "25565",
        "--username",
        "ClaudeBot"
      ]
    }
  }
}

Double-check that right --port and --host parameters were used. Make sure to completely reboot the Claude Desktop application (should be closed in OS tray).

Running

Make sure Minecraft game is running and the world is opened to LAN. Then start Claude Desktop application and the bot should join the game.

It could take some time for Claude Desktop to boot the MCP server. The marker that the server has booted successfully is a hammer icon that appears next to the chat.

You can give bot any commands through any active Claude Desktop chat. You can also upload images of buildings and ask bot to build them 😁

Don't forget to mention that bot should do something in Minecraft in your prompt. Because saying this is a trigger to run MCP server. It will ask for your permissions.

Using Claude 3.7 Sonnet could give you some interesting results. The bot-agent would be really smart 🫡

Example usage: shared Claude chat
