Heren MCP Server for Godot Engine Released

Unlike existing MCP servers, Heren Godot MCP runs a lightweight WebSocket daemon in the background to keep the Godot engine always active. This provides an environment where AI agents can interact with the engine instantly.

Key features are as follows:

• Ultra-fast response: Tasks complete in about 20ms with no engine cold-start wait time.
• Data persistence: Since the engine keeps running, sub-resources such as collision shapes, materials, and environments are reliably preserved in scene files.
• Powerful debugging: AI can resolve issues in real time through breakpoints, stack traces, variable inspection, and console output.
• Visual feedback: The GPU-accelerated screenshot feature lets AI directly check the viewport and real-time coordinates.

This project includes 15 designed tools supporting scene management, scripts, shaders, animation, debugging, and more, and is provided as open source.
