Introduction

The UBOS Asset Marketplace features the Minecraft MCP (Model Context Protocol) Server, a groundbreaking tool that bridges the gap between artificial intelligence and the immersive world of Minecraft. Powered by the Mineflayer API, this server allows AI assistants to control a Minecraft character in real-time, enabling a vast array of possibilities, from automated construction to dynamic world exploration and interactive gameplay. By leveraging natural language instruction, users can command their in-game avatar through AI, opening up new frontiers in gaming, education, and AI development. This integration highlights UBOS’s commitment to bringing AI Agents to every business department and empowering users with innovative solutions.

What is an MCP Server?

At its core, an MCP (Model Context Protocol) Server acts as a crucial intermediary, facilitating communication between Large Language Models (LLMs) and external environments. In the context of the Minecraft MCP Server, it enables AI models like Claude to understand and execute commands within the Minecraft universe. This is achieved by standardizing how applications provide context to LLMs, allowing the AI to access real-time data, interact with the game world, and perform actions based on natural language input.

Use Cases

The Minecraft MCP Server offers a diverse range of applications across various domains:

• Automated Construction: Imagine instructing your AI assistant to build a complex structure, such as a house, a castle, or even a sprawling city. The MCP Server allows you to define the design parameters using natural language, and the AI will then autonomously construct the building within the Minecraft world.
• Dynamic World Exploration: Send your AI-controlled character on expeditions to explore the vast Minecraft landscape. The AI can be programmed to search for specific resources, map uncharted territories, or even engage with other in-game entities.
• Educational Tool: The Minecraft MCP Server provides an engaging platform for learning about AI and programming. Students can experiment with different AI models, develop custom commands, and observe the results in a visually stimulating environment.
• AI Research and Development: Researchers can leverage the MCP Server to test and refine AI algorithms in a dynamic and interactive setting. Minecraft provides a controlled environment for evaluating AI performance in tasks such as pathfinding, resource management, and collaborative problem-solving.
• Interactive Storytelling: Create immersive narrative experiences within Minecraft by using AI to control character actions and dialogue. Players can interact with AI-driven characters, participate in branching storylines, and shape the outcome of the game.
• Game Development Prototyping: Game developers can rapidly prototype new gameplay mechanics and AI-driven features using the Minecraft MCP Server. This allows for faster iteration and experimentation, leading to more innovative and engaging game experiences.

Key Features

The Minecraft MCP Server boasts a rich set of features designed to empower users and unlock the full potential of AI-driven gameplay:

• Real-Time Control: The server enables real-time control of a Minecraft character through natural language instructions, allowing for seamless interaction between the user and the game world.
• Mineflayer API Integration: The server is built upon the Mineflayer API, a powerful library that provides a comprehensive interface for interacting with Minecraft servers. This ensures compatibility with a wide range of Minecraft versions and features.
• Model Context Protocol (MCP) Support: The server fully supports the Model Context Protocol, enabling seamless integration with AI models like Claude. This allows for advanced AI capabilities, such as natural language understanding, decision-making, and task planning.
• Available Commands: The server provides a comprehensive set of commands that allow the AI to interact with the Minecraft world. These commands include:
  • Movement: get-position, move-to-position, look-at, jump, move-in-direction, fly-to
  • Inventory: list-inventory, find-item, equip-item
  • Block Interaction: place-block, dig-block, get-block-info, find-block
  • Entity Interaction: find-entity
  • Communication: send-chat
• Easy Installation: The server can be easily installed via Smithery, a package manager for AI applications. This simplifies the setup process and allows users to quickly get started with AI-driven Minecraft gameplay.
• Configurable Parameters: The server’s parameters, such as the host, port, and username, can be easily configured to match the user’s specific Minecraft setup. This ensures compatibility with different Minecraft environments and configurations.
• Open-Source and Customizable: The server is open-source and fully customizable, allowing users to modify the code and add new features. This fosters innovation and collaboration within the AI and Minecraft communities.

Getting Started

To get started with the Minecraft MCP Server, follow these steps:

1. Prerequisites:

   • Ensure you have Git, Node.js, and a running Minecraft game (tested with Minecraft 1.21.4 Java Edition). You also need Claude Desktop installed.

2. Run Minecraft:

   • Create a singleplayer world and open it to LAN (ESC -> Open to LAN). The bot will attempt to connect using port 25565 and hostname localhost. You can configure these parameters in claude_desktop_config.json.

3. Installation via Smithery:

   • Use the following command to install the server for Claude Desktop: bash npx -y @smithery/cli install @yuniko-software/minecraft-mcp-server --client claude

4. MCP Configuration:

   • Open Claude Desktop and navigate to File -> Settings -> Developer -> Edit Config. This will open the installation directory.

   • Find the claude_desktop_config.json file and insert the following code:

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

   • Verify that the --port and --host parameters are correct. Reboot the Claude Desktop application.

5. Running:

   • Ensure that the Minecraft game is running and the world is open to LAN. Then, start the Claude Desktop application. The bot should automatically join the game.
   • The server has booted successfully when a hammer icon appears next to the chat.

6. Give Commands:

   • You can give the bot commands through any active Claude Desktop chat. Mention that the bot should do something in Minecraft to trigger the MCP server.
   • Example: “Claude, build a small house in Minecraft.”
