Minecraft RCON MCP Server

A Spring Boot application that provides a bridge between Model Context Protocol (MCP) and a Minecraft server's RCON interface, allowing AI models to send commands to a Minecraft server. Built with SpringAI.

Description

This project enables AI models using Spring AI's MCP functionality to interact with a Minecraft server through the RCON protocol. It provides a simple tool that can send commands to the Minecraft server and receive responses, making it possible for AI models to control and query the Minecraft server.

Prerequisites

• Java 21 or higher
• Maven 3.6 or higher
• A Minecraft server with RCON enabled

Building the Project

1. Clone the repository:

   git clone https://github.com/yourusername/minecraft-rcon-mcp.git
   cd minecraft-rcon-mcp
   

2. Build the project using Maven:

   ./mvnw clean package
   

   On Windows:

   mvnw.cmd clean package
   

3. The built JAR file will be located in the target directory:

   target/minecraft-rcon-mcp-1.0.0.jar
   

Configuration

The application can be configured using environment variables or a .env file in the project root directory.

Required Env Param Configuration

• RCON_HOST: The hostname or IP address of the Minecraft server (default: localhost)
• RCON_PORT: The RCON port of the Minecraft server (default: 25575)
• RCON_PASSWORD: The RCON password for authentication (required, no default)

Optional Configuration

• logging.file.name: The name of the log file (default: rconmcp.log)

Usage

Once the application is built and added to an MCP Client with your Env-Params, it exposes a Model Context Protocol (MCP) server that can be used by Spring AI clients to send commands to the Minecraft server.

The MCP server provides a tool called sendCommand that takes a Minecraft command as input and returns the response from the server.
