unreal-mcp

Use this skill to perform actions inside an Unreal Engine project via a live-editor MCP connection. Trigger when the user wants to change, query, or run something in their Unreal Engine project, not for conceptual or docs questions. Concrete triggers: spawn/move/duplicate/transform actors in a level, open a .uproject, add things around a PlayerStart, create or edit a Blueprint/Widget/Material/Niagara/Control Rig/Sequencer/Behavior Tree/GAS ability, read or write properties on actors (e.g. bIsLocked on BP_DoorActor), Live Coding recompile after editing C++ (AActor, UMyComponent::Method, UPROPERTY), or modify Static/Skeletal Mesh assets. Treat as Unreal context even without the word "Unreal": asset prefixes BP_, WBP_, M_, MI_, NS_, CR_, SK_, SM_, ABP_; UE C++ types/macros; .uproject; Content Browser; Outliner; PlayerStart; "in my game" plus UE signals. Skip for: pure conceptual/docs questions, Unity, Godot, or unrelated uses of "blueprint"/"sequencer"/"widget".
