AI Game Developer — Initial Setup

This guide walks through installing the unity-mcp-cli command-line tool and using it to set up a Unity project with AI Skills and MCP integration.


Prerequisites

Install Node.js

unity-mcp-cli requires Node.js ^20.19.0 || >=22.12.0 (Node 21.x is not supported). If you don't have Node.js installed:

Download the installer from https://nodejs.org/ and run it, or use a package manager:

winget install OpenJS.NodeJS.LTS

After installation, verify both node and npm are available:

node --version
npm --version

Install unity-mcp-cli Globally

Install the CLI globally so the unity-mcp-cli command is available system-wide:

bash
npm install -g unity-mcp-cli

Verify installation:

bash
unity-mcp-cli --version
Alternative: Run any command without installing globally using npx:
```bash
npx unity-mcp-cli --help
```

Quick Start — Full Project Setup

1. Install the Unity-MCP Plugin

Add the plugin to an existing Unity project:

bash
unity-mcp-cli install-plugin /path/to/unity/project
2. Configure MCP Tools

Enable all tools, prompts, and resources:

bash
unity-mcp-cli configure /path/to/unity/project \
--enable-all-tools \
--enable-all-prompts \
--enable-all-resources
3. Set Up MCP for Your AI Agent

Configure MCP integration for your AI agent (e.g., Claude Code, Cursor, Copilot):

bash
unity-mcp-cli setup-mcp claude-code /path/to/unity/project

List all supported agents:

bash
unity-mcp-cli setup-mcp --list
4. Generate AI Skills

Generate skill files for your AI agent (requires Unity Editor to be running with the plugin):

bash
unity-mcp-cli setup-skills claude-code /path/to/unity/project
5. Open Unity with MCP Connection
bash
unity-mcp-cli open /path/to/unity/project

Troubleshooting

  • `npm` not found: Node.js is not installed or not in your PATH. Reinstall Node.js and restart your terminal.
  • Plugin not appearing in Unity: After install-plugin, open the project in Unity Editor. The package manager resolves dependencies on project open.
  • Skills generation fails: Ensure Unity Editor is running with the MCP plugin installed and connected before running setup-skills.
