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