Unreal Engine API Documentation
Gives AI agents structured access to Unreal Engine C++ API documentation without requiring an Engine installation. Query function signatures, resolve #include paths, search for APIs by keyword, and check deprecation warnings across 100k+ records covering Engine Runtime, Editor modules, and built-in plugins like Enhanced Input and Gameplay Abilities. Supports UE 5.0 through 5.7 with automatic version detection from environment variables or .uproject files. The SQLite backend returns exact lookups in under 1ms and keyword searches in about 1ms, so you can verify `AActor::GetActorLocation` signatures or find `UCharacterMovementComponent` members in a single tool call instead of grepping source files. Especially useful if you're writing Blueprint graph nodes or editor tooling, since it indexes 158 UK2Node subclasses and the full KismetCompiler API surface.
