UnityMCPIntegration MCP Server

What does “UnityMCPIntegration” MCP Server do?

UnityMCPIntegration is a Model Context Protocol (MCP) server that enables AI assistants and agents to directly interact with and control the Unity game engine. By bridging Unity with external AI workflows, this integration empowers developers to automate and orchestrate in-game actions, manipulate scenes, or manage Unity assets programmatically. The server acts as a conduit, allowing AI models to send commands, receive updates, and manipulate Unity environments in real time. This fosters advanced development and testing workflows, such as automated game testing, procedural content generation, or dynamic scenario creation, all powered by AI. UnityMCPIntegration enhances productivity by enabling sophisticated agentic behaviors within Unity, making it a valuable tool for game developers, researchers, and anyone leveraging AI-driven Unity applications.

Use Cases of this MCP Server

• Automated Game Testing: Allows AI agents to interact with Unity scenes for continuous, automated playtesting, regression testing, and bug discovery, improving game quality and reducing manual QA effort.
• Procedural Content Generation: Empowers AI models to dynamically create or modify game assets, levels, or scenarios within Unity, fostering rapid prototyping and creative experimentation.
• AI-driven Gameplay: Enables integration of AI assistants that can control NPCs, adapt game logic, or respond to player actions programmatically through Unity’s API.
• Simulation and Training: Facilitates the use of Unity as a rich simulation environment for training reinforcement learning agents or testing autonomous systems.
• Real-time Scene Manipulation: Provides mechanisms for AI to modify Unity scenes, assets, or parameters on the fly, supporting interactive demos or AI-assisted design.

How to set it up

Windsurf

1. Ensure you have Node.js and Unity installed.
2. Locate the Windsurf configuration file (typically windsurf.config.json).
3. Add the UnityMCPIntegration server entry using a JSON snippet.
4. Save the configuration and restart Windsurf.
5. Verify the setup by checking the Windsurf logs for successful MCP server initialization.

{
  "mcpServers": {
    "unity-mcp": {
      "command": "npx",
      "args": ["@quazaai/unitymcpintegration@latest"]
    }
  }
}

Claude

1. Prerequisite: Install Node.js and Unity.
2. Find Claude’s MCP configuration file (e.g., claude.config.json).
3. Add the UnityMCPIntegration server under the mcpServers field.
4. Restart Claude.
5. Confirm the MCP server is running and accessible from Claude.

{
  "mcpServers": {
    "unity-mcp": {
      "command": "npx",
      "args": ["@quazaai/unitymcpintegration@latest"]
    }
  }
}

Cursor

1. Install Node.js and Unity.
2. Open Cursor’s settings or configuration file.
3. Insert the server configuration for UnityMCPIntegration.
4. Save changes and restart Cursor.
5. Check for MCP server activity in Cursor’s status panel.

{
  "mcpServers": {
    "unity-mcp": {
      "command": "npx",
      "args": ["@quazaai/unitymcpintegration@latest"]
    }
  }
}

Cline

1. Ensure Node.js and Unity are installed.
2. Access the Cline MCP configuration JSON file.
3. Add UnityMCPIntegration as an MCP server.
4. Save and restart Cline.
5. Validate the integration by inspecting Cline’s output/logs.

{
  "mcpServers": {
    "unity-mcp": {
      "command": "npx",
      "args": ["@quazaai/unitymcpintegration@latest"]
    }
  }
}

Securing API Keys

To secure API keys or sensitive credentials, use environment variables and reference them in your configuration as follows:

{
  "mcpServers": {
    "unity-mcp": {
      "command": "npx",
      "args": ["@quazaai/unitymcpintegration@latest"],
      "env": {
        "UNITY_API_KEY": "${UNITY_API_KEY}"
      },
      "inputs": {
        "unityProject": "/path/to/your/project"
      }
    }
  }
}

How to use this MCP inside flows

Using MCP in FlowHunt

To integrate MCP servers into your FlowHunt workflow, start by adding the MCP component to your flow and connecting it to your AI agent:

Click on the MCP component to open the configuration panel. In the system MCP configuration section, insert your MCP server details using this JSON format:

{
  "unity-mcp": {
    "transport": "streamable_http",
    "url": "https://yourmcpserver.example/pathtothemcp/url"
  }
}

Once configured, the AI agent is now able to use this MCP as a tool with access to all its functions and capabilities. Remember to change “unity-mcp” to whatever the actual name of your MCP server is and replace the URL with your own MCP server URL.

Overview

Our opinion

UnityMCPIntegration provides a powerful bridge between AI workflows and the Unity engine, but the lack of explicit prompts, resources, and tool documentation in the repository limits its immediate utility for developers seeking out-of-the-box workflows. Its setup is straightforward, and support for secure API key management is a plus. However, more detailed documentation and examples would greatly enhance its usability.
