Unity-MCPMCP Server43/100 via “asp.net core mcp server with signalr bidirectional communication”
AI Skills, MCP Tools, and CLI for Unity Engine. Full AI develop and test loop. Use cli for quick setup. Efficient token usage, advanced tools. Any C# method may be turned into a tool by a single line. Works with Claude Code, Gemini, Copilot, Cursor and any other absolutely for free.
Unique: Uses SignalR for persistent bidirectional WebSocket communication instead of stateless HTTP, enabling real-time streaming of tool results and resource updates. Automatically manages server binary lifecycle (download, launch, shutdown) through the Unity Editor plugin, eliminating manual server setup.
vs others: More responsive than REST-based tool calling because SignalR maintains persistent connections and supports server-initiated messages, enabling real-time feedback loops between AI and Unity without polling.
