How to Set Up and Use Unreal Engine 5 MCP
Unreal MCP is an AI bridge for Unreal Engine 5 that exposes over 280 editor commands across 13 categories — including materials, Blueprints, Niagara VFX, StateTree, data tables, Mass Entity, Enhanced Input, UMG widgets, and performance profiling — to any MCP-compatible AI client. It consists of a C++ Unreal plugin that runs a TCP server inside the editor and a Python MCP server that translates MCP tool calls into engine commands. Teams using Claude Code, Cursor, or Windsurf can describe game logic, VFX systems, or UI layouts in natural language and have them built directly in the Unreal Editor.
Prerequisites
- Unreal Engine 5.7 or later (earlier 5.x builds may work but are not officially supported)
- Python 3.10 or later
- npm (for the unrealcli package) or pip (for the unrealmcp MCP server package)
- Required UE5 plugins enabled: PythonScriptPlugin, EditorScriptingUtilities, EnhancedInput
- An MCP client such as Claude Code, Cursor, Windsurf, or VS Code
Install the UnrealMCP plugin into your project
Clone the Unreal-MCP repository into your project's Plugins directory, then run the platform-specific install script to compile the plugin.
git clone https://github.com/aadeshrao123/Unreal-MCP.git Plugins/UnrealMCP
# macOS/Linux:
bash Plugins/UnrealMCP/install.sh
# Windows:
cmd /c Plugins\UnrealMCP\install.batEnable required plugins in Unreal Editor
Open your UE5 project, go to Edit > Plugins, and ensure PythonScriptPlugin, EditorScriptingUtilities, and EnhancedInput are all enabled. Restart the editor after enabling them.
Install the Python MCP server package
Install the unrealmcp Python package, which acts as the MCP server that bridges AI clients to the Unreal plugin's TCP server.
pip install unrealmcpInstall the CLI tool for direct command access
Install unrealcli globally via npm to get the ue-cli command, useful for scripting and verifying the connection to the running Unreal Editor.
npm install -g unrealcliVerify the connection to Unreal Editor
With the Unreal Editor open and the plugin active, run a health check to confirm the MCP server can reach the editor's TCP socket.
ue-cli health_checkConfigure your MCP client
Add the unrealmcp server to your MCP client config. For Claude Code add it to .mcp.json, for Cursor add it to .cursor/mcp.json. The server connects to the Unreal Editor on port 55557 by default.

Example prompts for controlling Unreal Engine 5 through the MCP server.
- "Create a new material called M_RedRock and set it to a dark red metallic look"
- "Spawn a StaticMeshActor called Boulder at location (200, 0, 50)"
- "Create a Blueprint class called BP_Enemy that inherits from Character"
- "Add a new row to the DT_Items data table with name CopperOre and StackSize 100"
- "Start a performance trace capturing CPU and GPU channels, then analyze the results"Troubleshooting Unreal Engine 5 MCP
health_check fails with connection refused
The Unreal Editor must be open and the UnrealMCP plugin must be enabled and loaded. Check that the plugin compiled successfully by looking in the Unreal Output Log for 'UnrealMCP: TCP server started'. The default port is 55557 — override it with UNREAL_MCP_PORT if there is a conflict.
Plugin fails to compile
Ensure PythonScriptPlugin and EditorScriptingUtilities are enabled in the Unreal Editor plugins panel. Rerun install.sh or install.bat after enabling them. Check that your UE5 version is 5.7 or later.
Commands time out on large operations
Niagara VFX graph operations and large Blueprint compilations can take longer than the default 30-second timeout. Pass --timeout 300 to ue-cli commands, or set a longer timeout in your MCP client configuration.
