Field manual for driving Unreal Engine 5.7 / 5.8 through MCP. Engine-level gotchas, silent-fail edges, crash patterns, and the call sequences that actually work — applicable regardless of which MCP server you're using (Epic's official ModelContextProtocol plugin, custom servers, or anything else). Auto-trigger when Unreal Engine MCP tools are detected in a session, or when the user mentions Unreal Engine, UE5, Blueprints, Niagara, MetaSound, materials, or any UE editor automation workflow. This skill contains hard-won knowledge from real debugging sessions — most entries trace back to an actual editor crash or hours-long faceplant. Ignoring it when UE5 MCP tools are present will lead to wasted time hitting known dead ends.
