UnrealMCP Plugin

This plugin allows AI agents to directly modify your Unreal Engine project. While it can be a powerful tool, it also comes with risks:

- AI agents may make unexpected changes to your project
- Files could be accidentally deleted or modified
- Project settings could be altered
- Assets could be overwritten
- Always use source control (like Git or Perforce) with your project
- Make regular backups of your project
- Test the plugin in a separate project first
- Review changes before committing them

By using this plugin, you acknowledge that:

- You are solely responsible for any changes made to your project
- The plugin author is not responsible for any damage, data loss, or issues caused by AI agents
- You use this plugin at your own risk

- TCP server implementation for remote control of Unreal Engine
- JSON-based command protocol for AI tools integration
- Editor UI integration for easy access to MCP functionality
- Comprehensive scene manipulation capabilities
- Python companion scripts for client-side interaction

These are what I have in mind for development as of 3/14/2025 I'm not sure what's possible yet, in theory anything, but it depends on how good the integrated LLM is at utilizing these tools.

- Basic operations working
- Python working
- Materials
- User Extensions (in progress)
- Asset tools
- Blueprints
- Niagara VFX
- Metasound
- Landscape (I might hold off on this because Epic has mentioned they are going to be updating the landscape tools)
- Modeling Tools
- PCG

- Unreal Editor Installation (Tested with 5.3, but should work on 5.0+)
- Python 3.7+ (This can run with your existing python install)
- MCP compatible LLM (Claude for Desktop, Cursor, etc.)
- Setup: run setup_unreal_mcp.bat in MCP folder as per instructions in MCP/README_MCP_SETUP.md

If you want to use UnrealMCP with Cursor, follow these simple steps:
- Clone or download this repository as a zip
- Create a new Unreal Project, or open an existing one
- Create a "Plugins" folder in your project directory if it doesn't exist
- Unzip or copy this repository into the Plugins folder
- Runsetup_cursor_mcp.batin the MCP folder
- Open your Unreal project and enable the plugin in Edit > Plugins (if not already enabled)
- Start Cursor and ask it to work with your Unreal project

That's it! The setup script will automatically configure everything needed for Cursor integration.
- Clone or download this repository as a zip
- Create a new Unreal Project, or open an existing one
- Create a "Plugins" folder in your project directory if it doesn't exist
- Unzip or copy this repository into the Plugins folder
- Setup MCP

- Run thesetup_unreal_mcp.batscript in the MCP folder (seeMCP/README_MCP_SETUP.mdfor details)
- This will configure Python and your AI assistant (Claude for Desktop or Cursor)

- For Claude for Desktop: follow the instructions in the "With Claude for Desktop" section below
- For Cursor: follow the instructions in the "With Cursor" section below

You will need to find your installation directory for Claude for Desktop. Find claude_desktop_config.json and add an entry and make it look like so:

Windows:%APPDATA%\Claude\claude_desktop_config.json

Contributions are welcome, but I will need some time to wrap my head around things and cleanup first, lol
