unreal-mcp

MCP server for Unreal Engine that uses Unreal Python Remote Execution

Differences

This server does not require installing a new UE plugin as it uses the built-in Python remote execution protocol.

Adding new tools/features is much faster to develop since it does not require any C++ code.

It can support the full Unreal Engine Python API

Note

• This is not an official Unreal Engine project.
• Your AI agents or tools will have full access to your Editor.
• Review any changes your Client suggests before you approve them.
