What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Connection: Runs on your computer
Transport: stdio
Category: Developer tools
You need to fill in: UNITY_PROJECT_PATH

Install

Pick the AI app you use, then copy the settings.

Before you install

Basic checks: 1 of 1 passed
Runs on your computer with your user’s permissions (files, network, apps).
You fill in yourself: UNITY_PROJECT_PATH

You need

npmNode.js installed (for the npx command)

Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "unity": {
      "command": "npx",
      "args": [
        "-y",
        "unity-mcp-server"
      ],
      "env": {
        "UNITY_PROJECT_PATH": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add unity --env UNITY_PROJECT_PATH=your-value -- npx -y unity-mcp-server

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "unity": {
      "command": "npx",
      "args": [
        "-y",
        "unity-mcp-server"
      ],
      "env": {
        "UNITY_PROJECT_PATH": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "unity": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "unity-mcp-server"
      ],
      "env": {
        "UNITY_PROJECT_PATH": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

UNITY_PROJECT_PATH required env
Absolute path to your Unity project root (required)

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is Unity MCP Server safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: UNITY_PROJECT_PATH

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.7.0) reached the registry 3 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

Unity MCP Server

MCP server for Unity — Gives AI assistants structured access to your Unity project from any MCP-capable IDE or app. No Unity Editor required.

Your IDE talks to this server; the server reads your Unity project folder and answers with project info, build scenes, scripts, prefabs, and more — so the AI can help without opening the Editor.

Overview

Editor-free — Reads only from the project filesystem.
One server, many projects — Set UNITY_PROJECT_PATH per project in your MCP config.
MCP-native — Works with any client that supports the Model Context Protocol (tools over stdio).

Supported IDEs and clients

This server uses the standard MCP protocol over stdio and exposes tools. Any IDE or app that can run an MCP server and pass environment variables will work. Commonly used clients include:

Client	Notes
Cursor	Add server to MCP settings; set `UNITY_PROJECT_PATH` in `env`.
Claude Desktop	Add to `claude_desktop_config.json`; same command + env pattern.
Claude Code	MCP support including tools.
VS Code	Use an MCP extension (e.g. GenAI / Copilot MCP); configure server and `UNITY_PROJECT_PATH`.
Windsurf	Add MCP server with command and env.
Continue	Configure MCP server in Continue settings.
Cline	MCP tools and resources.
Other	Any client that supports MCP tools over stdio (e.g. Zed, Roo Code, LibreChat, custom agents).

Configuration is the same everywhere: command = node, args = path to dist/index.js, env = UNITY_PROJECT_PATH = your Unity project root. See Configuration below for a Cursor example; other clients use the same structure in their own config format.
