name	ue-mcp-native-cpp
description	Use when writing or modifying native C++ UCLASSes in an Unreal project via ue-mcp. Covers create_cpp_class → write_cpp_file → live_coding_compile loop, when to use build vs Live Coding, and the add_module_dependency workflow. Pulls in any time the user asks to write a new native class, add a UPROPERTY, or implement a UFUNCTION.

ue-mcp native C++ authoring

The project tool wraps GameProjectUtils::AddCodeToProject and ILiveCodingModule so agents can author native C++ end-to-end without Python or the editor UI.

The authoring loop

1. Pick a module. project(action="list_project_modules") enumerates the project's native modules (name, host type, source path). Feed the module name into create_cpp_class.
2. Create the class. project(action="create_cpp_class", className, parentClass?, moduleName?, classDomain?, subPath?) writes .h and .cpp using the same engine template that File → New C++ Class uses. The class-name prefix (A, U, F) is derived from parentClass — pass the bare name ("BotSpawner", not "ABotSpawner").
3. Inspect the generated files. project(action="read_cpp_header", headerPath=...) and project(action="read_cpp_source", sourcePath=...). Both paths are relative to or absolute within it.
