What it does

Unity Initial Setup is an agent skill from IvanMurzak/Unity-MCP. Provides an initial setup for AI Skills, unity-mcp-cli command line tool installation and everything else that is helpful to set up at the start of the project. Essential packages, and basic configurations.

Its SKILL.md is about 860 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Game Development, covering Game development and MCP servers. It works with Model Context Protocol, Node.js and Unity. The repository describes itself as: AI Skills, MCP Tools, and CLI for Unity Engine. Full AI develop and test loop. Use cli for quick setup. Efficient token usage, advanced tools. Any C method may be turned into a… The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve Game development
  • Tasks that involve MCP servers

Example prompts

  • “Use the unity-initial-setup skill to provide an initial setup for AI Skills, unity-mcp-cli command line tool installation and everything else that…”
  • “/unity-initial-setup”

Requirements

  • Node.js

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. Install the Unity-MCP Plugin
  2. Configure MCP Tools
  3. Set Up MCP for Your AI Agent
  4. Generate AI Skills
  5. Open Unity with MCP Connection

What it can do on your machine

Read from SKILL.md and the folder at commit 4c8056f. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • npm
    • winget
    • node

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • nodejs.org

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Unity Initial Setup loads about 855 tokens when it runs. Until then it costs about 57 tokens; SKILL.md has 334 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~57
When it runs · the whole SKILL.md, loaded when a task matches
~855

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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

Common Commands Reference

CommandDescription
unity-mcp-cli install-plugin <path>Install Unity-MCP plugin into a project
unity-mcp-cli remove-plugin <path>Remove Unity-MCP plugin from a project
unity-mcp-cli configure <path> --listList current MCP configuration
unity-mcp-cli setup-mcp <agent> <path>Write MCP config for an AI agent
unity-mcp-cli setup-skills <agent> <path>Generate skill files for an AI agent
unity-mcp-cli create-project <path>Create a new Unity project
unity-mcp-cli install-unity <version>Install a Unity Editor version
unity-mcp-cli open <path>Open a Unity project in the Editor
unity-mcp-cli run-tool <tool> <path>Execute an MCP tool via HTTP API

Add --verbose to any command for detailed diagnostic output.

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.
