About mcp-unity
CoderGamester/mcp-unity
Model Context Protocol (MCP) plugin to connect with Unity Editor — designed for Cursor, Claude Code, Codex, Windsurf and other IDEs
Provides AI agents with 25+ tools for scene manipulation, asset management, and testing—including GameObject modification, prefab creation, scene loading, and script recompilation—via a Node.js MCP server that communicates with Unity Editor through stdio transport. Automatically surfaces Unity's PackedCache to IDE workspaces for improved code intelligence on engine dependencies, bridging the gap between AI coding assistants and real-time game development workflows.
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.
