What is an MCP Server?

An MCP Server is a tool based on the Model Context Protocol. It encapsulates the editor functions of Unreal Engine into a service that can be called by external Agents through network interfaces, thereby enabling automated task processing.

How to use an MCP Server?

You need to install and configure the MCP Server first, and then execute the required tasks through API calls, such as automated iteration and build processes.

Applicable Scenarios

The MCP Server is suitable for scenarios that require frequent interaction with Unreal Engine, such as automated testing, continuous integration, and asset optimization in game development.

Main Features

Cross - platform Support

Compatible with Windows systems. Future versions will be extended to more operating systems.

Automated Iteration

Implement automated task scheduling through API interfaces to improve work efficiency.

Flexible Expansion

Users can customize the functional modules of the MCP Server according to their needs.

Advantages

Simplify complex operation processes

Improve development efficiency

Support multi - task parallel processing

Limitations

Currently only supports the Windows environment

Some advanced functions require manual configuration

How to Use

Clone the project to the plugin directory

Clone the MCP Server code to the plugin folder of the Unreal Engine project and compile it.

Start the MCP Server

Ensure that the Python environment is installed and run the MCP Server script.

Configure the Agent

Set the MCP Server address and port on the Agent side.

Usage Examples

Automated Iteration Example

Automatically complete model update and export tasks through the MCP Server.

Continuous Integration Example

Use the MCP Server for automated testing and building.

🚀 UE-Editor-MCPServer

This project encapsulates the UE Editor as an MCP Server for Agent use, enabling automated iteration of the Agent.

🚀 Quick Start

Project Setup

Clone the current project into the plugin directory of your project or engine and complete the compilation.
- The plugin directory of UE is usually located at Content/Plugins or other custom locations.
Ensure that the Python environment is configured correctly, especially that the pip source connection is smooth (you can try using domestic mirrors for acceleration).
After starting the UE engine, the MCP Server will start automatically.

Notes

⚠️ Important Note

This project is currently developed based on C++. It is planned to be listed in the store in the future. If you need to use it on other versions of UE, please adjust the Python and plugin versions by yourself to ensure compatibility.

⚠️ Important Note

If you encounter compilation problems, you may need some C++ knowledge.

💻 Usage Examples

Basic Usage

Currently, only an example version of the MCP Server is provided. If you want to add features or modify behaviors, you can directly modify the code in .Content/Python/MCPServer.py.

# The example code will show the basic usage and how to implement the functions.
# If you need more advanced features, please refer to the project documentation or community discussions.

Project Value and Future Plans

Automated Iteration: Through the MCP Server, the Agent can more efficiently complete repetitive tasks in the UE Editor, improving development efficiency.
Cross - platform Support: It is planned to gradually support UE5 and some UE4 versions to expand the scope of application.
Community Collaboration: All developers are welcome to contribute code or provide suggestions to jointly improve the project's functionality.

Summary

This project aims to achieve automated iteration of the Agent by encapsulating the UE Editor as an MCP Server. The current version is based on UE 5.5 and runs stably on Windows. Beginners can quickly get started by cloning the project, configuring the environment, and modifying the Python script. In the future, it is planned to support more UE versions and be listed in the store. Your valuable suggestions are welcome!
