Package Exports

@runreal/unreal-mcp
@runreal/unreal-mcp/dist/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@runreal/unreal-mcp) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

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
