About unity-mcp

CoplayDev/unity-mcp

Unity MCP acts as a bridge, allowing AI assistants (like Claude, Cursor) to interact directly with your Unity Editor via a local MCP (Model Context Protocol) Client. Give your LLM tools to manage assets, control scenes, edit scripts, and automate tasks within Unity.

Implements a comprehensive Python-based MCP server using HTTP transport that operates locally within the Unity Editor, exposing 40+ tools across physics, animation, graphics, builds, and scene management alongside introspection resources like `unity_reflect` for live API inspection. The architecture supports multi-instance routing, async long-running operations with polling, batch execution for performance optimization, and integrates with popular LLM clients (Claude, Cursor, VS Code Copilot, Windsurf) through configurable connection protocols. Available as a Git-based package in the Unity Package Manager, Asset Store, and OpenUPM with Python 3.10+ and the `uv` package manager as runtime dependencies.

About unity-mcp-server

AnkleBreaker-Studio/unity-mcp-server

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.
