Game engine runtime mcp

A production-grade Model Context Protocol (MCP) server that connects Anthropic's Claude AI directly with game engine runtimes (Unity & Godot). It enables automated testing, real-time error log filtering, scene hierarchy inspection, and safe file writing inside an isolated sandbox environment.

🌟 Key Features

• Scene Hierarchy Inspection: Parse Unity (.unity) and Godot (.tscn) scenes to give Claude complete awareness of active nodes, GameObjects, and attached components.

• Headless Test Runner: Execute game engine unit/integration tests directly without opening the GUI, avoiding command timeouts via asynchronous process handling.

• Token-Optimized Log Filtering: Extracts only stacktraces, null-pointer exceptions, and compilation errors from engine logs to prevent blowing past context limits.

• Strict Security Sandboxing: Protects host filesystems by restricting file read/write operations strictly to permitted game project folders.
