How to Set Up and Use Unreal Engine 5
ue5-mcp is a Python-based MCP server paired with an Unreal Engine 5 editor plugin that exposes your UE5 project's Blueprints, Materials, and Animation Blueprints to AI assistants over a local HTTP server. The editor plugin runs inside the UE5 process and makes your project assets addressable, while the MCP wrapper connects this to Claude Code or other MCP clients so you can issue natural language instructions to read, modify, and create Blueprints directly. Game developers use it to accelerate Blueprint authoring, automate refactoring across large projects, document game systems, and iterate on component logic without leaving their AI assistant.
Prerequisites
- Unreal Engine 5 installed and a UE5 project open
- Python 3.9 or later (for the MCP server wrapper)
- Claude Code or another MCP client that supports local HTTP servers
- Git (to clone and install the plugin into your project)
- Sufficient UE5 editor running time — the plugin requires the editor to be open
Install the ue5-mcp plugin into your project
The easiest way to set up the plugin is to tell Claude Code to install it for you from the repo URL. Claude will clone the plugin and configure the MCP server.
Set up https://github.com/mirno-ehf/ue5-mcp in my projectClone the repository manually (alternative)
If you prefer manual installation, clone the repo and follow the setup instructions in the repository to place the UE5 plugin in your project's Plugins/ directory.
git clone https://github.com/mirno-ehf/ue5-mcp.gitEnable the plugin in Unreal Engine
Open your UE5 project, navigate to Edit → Plugins, search for the ue5-mcp plugin, enable it, and restart the editor. The plugin will start its local HTTP server automatically.
Configure your MCP client
Add the ue5-mcp Python server to your MCP client config, pointing it at the local HTTP server the UE5 plugin exposes. Check the repo README for the exact port and endpoint after installation.
{
"mcpServers": {
"ue5": {
"command": "python",
"args": ["path/to/ue5-mcp/server.py"]
}
}
}Verify the connection
With your UE5 editor open and the plugin enabled, ask Claude to list available Blueprints in your project to confirm the MCP server is communicating with the editor.

}Prompts to try
Natural language prompts that the ue5-mcp plugin handles for Blueprint editing and project exploration.
- "Add a health component to my player character Blueprint"
- "Find everywhere I use GetActorLocation and replace it with a cached version"
- "What does my damage system do? Walk me through the relevant Blueprints"
- "Create a new Blueprint that extends ActorComponent and add a float variable called Speed"
- "List all Blueprint classes in the project that inherit from Character"Troubleshooting Unreal Engine 5
The MCP server cannot connect to the UE5 editor plugin
The UE5 editor must be open and the plugin must be enabled in your project. Check Edit → Plugins to confirm it is active, then restart the editor and the MCP server.
Python server fails to start with import errors
Make sure you are using Python 3.9+ and have installed any dependencies listed in the repo's requirements.txt with: pip install -r requirements.txt
Blueprint changes made via Claude are not visible in the editor
The editor may need a refresh. Try clicking 'Compile' on the affected Blueprint in the UE5 editor, or use the 'Refresh' option in the asset browser to reload the modified assets.
