About This MCP Server
✨ AI Game Developer — Unity MCP
中文 | 日本語 | Español
Unity MCP is an AI-powered game development assistant for Editor & Runtime. Connect Claude, Cursor, & Windsurf to Unity via MCP. Automate workflows, generate code, and enable AI within your games.
Unlike other tools, this plugin works inside your compiled game, allowing for real-time AI debugging and player-AI interaction.

MCP - Model Context Protocol. In a few words, that is USB Type-C for AI, specifically for LLM (Large Language Model). It teaches LLM how to use external features. Such as Unity Engine in this case, or even your custom C# method in your code. Official documentation.
It is an application with a chat window. It may have smart agents to operate better, it may have embedded advanced MCP Tools. In general well done MCP Client is 50% of the AI success of executing a task. That is why it is very important to choose the best one for usage.
It is a bridge between MCP Client and "something else", in this particular case it is Unity Engine. This project includes MCP Server.
MCP Tool is a function or method that the LLM can call to interact with Unity. These tools act as the bridge between natural language requests and actual Unity operations. When you ask the AI to "create a cube" or "change material color," it uses MCP Tools to execute these actions.
MCP Resource provides read-only access to data within your Unity project. Unlike MCP Tools that perform actions, Resources allow the LLM to inspect and understand your project's current state, assets, and configuration. Think of them as "sensors" that give the AI context about your project.
MCP Prompt allows you to inject pre-defined prompts into the conversation with the LLM. These are smart templates that can provide context, instructions, or knowledge to guide the AI's behavior. Prompts can be static text or dynamically generated based on your project's current state.
Connect Unity MCP to LLM clients such as Claude or Cursor using the integrated AI Connector window. Custom clients are also supported.
The system is highly extensible - you can define custom MCP Tools, MCP Resource or MCP Prompt directly in your Unity project codebase, exposing new capabilities to AI or automation clients. This makes Unity MCP a flexible foundation for building advanced workflows, rapid prototyping, and integrating AI-driven features
Capabilities
✔️ Agent-ready tools - Find anything you need in 1-2 steps✔️ Instant compilation - C# code compilation & execution using Roslyn for faster iteration✔️ Full asset access - Read/write access to assets and C# scripts✔️ Intelligent feedback - Well-described positive and negative feedback for proper issue understanding
Tools & Endpoints12
Example Workflow
Communicate with the AI (LLM) in your MCP Client. Ask it to do anything you want. The better you describe your task or idea, the better it will perform the job.
Some MCP Clients allow you to choose different LLM models. Pay attention to this feature, as some models may work much better than others.
> Make sure Agent mode is turned on in your MCP client
What Problems It Solves
- Use Unity MCP in your game/app. Use Tools
- Resources or Prompts. By default there are no tools
- you would need to implement your custom.
Why Use Github IvanMurzak Unity MCP?
- Unity MCP provides advanced tools that enable the LLM to work faster and more effectively
- avoiding mistakes and self-correcting when errors occur. Everything is designed to achieve your goals efficiently.
