Give AI agents complete authoring access to UE 5.7 — Blueprints, materials, biome foliage, animation, levels, sequencer, and much more. Native C++. Zero bridges. In-process. Everything your AI agent needs to build. Every major Unreal Engine authoring system is exposed — from high-level game logic down to material expression nodes and animation curves. Works with any MCP-enabled AI assistant: Rekall UE speaks the Model Context Protocol. If your agent supports MCP, it works.
