🚀 Creating an MCP Server (Claude Version)

This guide provides a step - by - step process to create an MCP server using Claude for code obfuscation.

🚀 Quick Start

✨ Features

Compile and modify Minecraft game code.
Protect code copyright through obfuscation.
Create a customized Minecraft server.

📦 Installation

1. Prepare Tools and Environment

First, make sure you have installed the following tools:

Java Development Kit (JDK): Used to compile Java programs.
Minecraft Coder Pack (MCP): Used to decompile Minecraft game code.
Claude or other similar obfuscation tools: Used to obfuscate the code and protect copyright.

Next, download and install these tools, and ensure they are configured correctly. Pay special attention that JDK and MCP need to be configured correctly according to the official documentation to avoid errors in the subsequent process.

2. Download Minecraft Game Files

Download the Minecraft game files (usually the minecraft.jar file) from the official Minecraft website or other legal channels. Make sure you download the version you want to modify (e.g., 1.18, 1.19, etc.).

💻 Usage Examples

3. Decompile Minecraft Code with MCP

Place the minecraft.jar file in the working directory of MCP. Open the MCP tool, select the decompilation option, and specify the output path. After the decompilation is completed, you will see the source code files of Minecraft in the specified folder.

Note: MCP may require some additional configuration, such as setting the path of the JDK or selecting a specific target version.

4. Modify or Extend Minecraft Code

Open the decompiled code files and make modifications according to your needs. You can add new features, fix bugs, or adjust game rules. The Claude tool can help you obfuscate the code to protect your modifications from being easily understood by others.

When modifying the code, please note the following points:

Maintain the code structure: Do not randomly delete or modify the core Minecraft code, otherwise, the game may crash.
Test each feature: After each major modification, run the game and test the new features to ensure that no errors are introduced.
Keep a modification log: Save detailed records of each modification for subsequent debugging and optimization.

5. Obfuscate the Code with Claude

After completing the code modifications, use the Claude tool to obfuscate the code. Claude can hide the structure of the original code by renaming variables, methods, and classes, thereby improving the security of the code.

When setting the parameters of Claude, make sure to select options suitable for the Minecraft project and avoid over - obfuscation that may cause the code to fail to run.

6. Recompile the Modified Code

Return the obfuscated code files to the MCP tool and select the recompilation option. MCP will generate a new minecraft.jar file containing your modified and obfuscated code.

Note: During the compilation process, you may encounter some error or warning messages. Please solve the problems according to the prompts and ensure that all errors are fixed before proceeding to the next step.

7. Test the New Version of Minecraft

Replace the original Minecraft game file with the recompiled minecraft.jar file, run the game, and test whether the modified features work properly. If any exceptions occur, check the log files for more information.

8. Distribution or Deployment

If you want to share your modified version of Minecraft with others, you can distribute it by packaging it into a mod or other distribution methods. Make sure to comply with relevant copyright and license agreements to avoid legal issues.
