Unity MCP Server — 268 tools for AI-assisted game development. Connect Claude, Cursor, or any MCP client to Unity Editor & Unity Hub. Scene management, GameObjects, components, builds, profiling, Shader Graph, Amplify, terrain, physics, NavMesh, animation, MPPM multiplayer & more. Free & open source by AnkleBreaker Studio.
Implements a two-tier tool architecture (core + advanced proxy) to avoid overwhelming MCP clients, while communicating with Unity Editor via a companion HTTP plugin and Unity Hub through CLI commands. Supports multi-instance editor discovery with automatic port reconnection, enabling seamless workflows across multiple concurrent Unity projects or ParrelSync clones.
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.
