# Minecraft MCP Server

___ > [!IMPORTANT] > Currently supports Minecraft version 1.21.11. Newer versions may not work with this MCP server, but we will add support as soon as possible. https://github.com/user-attachments/assets/6f17f329-3991-4bc7-badd-7cde9aacb92f A Minecraft bot powered by large language models and [Mineflayer API](https://github.com/PrismarineJS/mineflayer). This bot uses the [Model Context Protocol](https://github.com/modelcontextprotocol) (MCP) to enable Claude and other supported models to control a Minecraft character.

## Prerequisites - Git - Node.js (>= 20.10.0) - A running Minecraft game (the setup below was tested with Minecraft 1.21.8 Java Edition included in Microsoft Game Pass) - An MCP-compatible client. Claude Desktop will be used as an example, but other MCP clients are also supported ## 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](https://claude.ai/download) 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: ```json { "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:

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 Sonnet could give you some interesting results. The bot-agent would be really smart 🫡 Example usage: [shared Claude chat](https://claude.ai/share/535d5f69-f102-4cdb-9801-f74ea5709c0b) ## Available Commands Once connected to a Minecraft server, Claude can use these commands: ### Movement - `get-position` - Get the current position of the bot - `move-to-position` - Move to specific coordinates - `look-at` - Make the bot look at specific coordinates - `jump` - Make the bot jump - `move-in-direction` - Move in a specific direction for a duration ### Flight - `fly-to` - Make the bot fly directly to specific coordinates ### Inventory - `list-inventory` - List all items in the bot's inventory - `find-item` - Find a specific item in inventory - `equip-item` - Equip a specific item ### Block Interaction - `place-block` - Place a block at specified coordinates - `dig-block` - Dig a block at specified coordinates - `get-block-info` - Get information about a block - `find-block` - Find the nearest block of a specific type ### Furnace - `smelt-item` - Smelt items using a furnace-like block ### Entity Interaction - `find-entity` - Find the nearest entity of a specific type ### Communication - `send-chat` - Send a chat message in-game - `read-chat` - Get recent chat messages from players ### Game State - `detect-gamemode` - Detect the gamemode on game ## Contributing Feel free to submit pull requests or open issues for improvements.
