Effectiveness · benchmark pending
We haven't benchmarked UE-MCP yet, so its score is provisional — computed from safety, maintenance, and documentation only, with popularity given no weight. When we benchmark it, we measure whether it produces materially better output than a frontier model alone, and that result leads the score. How we measure.
About UE-MCP
Description · AI-summarised from the db-lyon README
UE-MCP is a TypeScript/Node.js MCP server that bridges AI assistants to Unreal Engine through a C++ plugin. It provides comprehensive programmatic control over blueprints, materials, levels, actors, animation, VFX, landscape, PCG, gameplay systems (GAS, physics, navigation, behavior trees), networking, UI, and the editor itself. Includes an interactive CLI setup, YAML-based flow engine for multi-step workflows, and direct file-system access to project configs. Supports Windows (UE 5.4–5.7) and Linux (UE 5.6+).
