About UnityMCP

isuzu-shiranui/UnityMCP

Unity Editor integration with Model Context Protocol (MCP) enabling AI assistants like Claude to interact with Unity projects. Features a TypeScript MCP server and C# Unity plugin with extensible command handler architecture, TCP/IP communication, and dynamic plugin discovery.

Supports all three MCP handler types (commands, resources, and prompts) with automatic discovery on both C# and TypeScript sides, enabling bidirectional AI-Unity workflows. The framework uses a scalable plugin architecture where custom handlers implement well-defined interfaces and are automatically registered via reflection, with communication serialized as JSON over TCP/IP between the Unity Editor and Claude Desktop. Includes built-in installer tooling for integrating the TypeScript MCP server with Claude Desktop configuration, plus sample handlers demonstrating code execution capabilities.
