About Unity MCP Template

What is Unity MCP Template: Effortless Control & Endless Creativity?

Imagine a bridge between Unity's powerhouse and the flexibility of TypeScript—this template does exactly that! It’s a starter project that lets you effortlessly connect your Unity games with MCP servers, enabling seamless communication without the headache of version conflicts or complex setups. Perfect for dev teams who want to build custom tools without wrestling with legacy package issues.

How to Use Unity MCP Template: Effortless Control & Endless Creativity?

Let’s dive right in! First, spin up the TypeScript server with two quick npm commands. Then, plug it into Claude Desktop with a JSON config tweak—think of it as plugging in a USB drive for your dev workflow. Once connected, start crafting your own tools by mirroring the structure in CreateObjectTools (Unity side) and createObject (TypeScript side). It’s like LEGO for developers: snap pieces together and watch your ideas come alive.

Unity MCP Template Features

Key Features of Unity MCP Template: Effortless Control & Endless Creativity?

✅ No fluff dependencies: We ditched bloated packages like NewtonsoftJSON to keep things lean. ✅ Visual dev comfort: The UnityMCP-ShowWindow gives you an in-editor control panel via IMGUI—no more context-switching madness. ✅ Future-proof sockets: The TCP setup is already on a revamp roadmap (shoutout to the community-driven GitHub discussion linked below). Trust us, this isn’t just a quick fix—it’s a foundation.

Use Cases of Unity MCP Template: Effortless Control & Endless Creativity?

Need to spawn objects dynamically? Tweak game variables on the fly? Or maybe automate repetitive tasks like level generation? This template’s your playground. Think of it as a Swiss Army knife for Unity-MCP workflows. For example:

Build a “God Mode” toggle that syncs instantly between editor and server
Create a real-time debug overlay that updates as you tweak TypeScript logic
Automate QA tests by triggering Unity actions from external scripts

Unity MCP Template FAQ

FAQ from Unity MCP Template: Effortless Control & Endless Creativity?

“Does this work with older Unity versions?” Yep! We’ve minimized package reliance specifically for legacy compatibility. “Why the TCP setup is being changed?” The current client-server reversal was a temporary fix for a TypeScript SDK bug—we’re flipping it back to standard architecture soon (track progress here). “Can I use this for live projects?” Absolutely! Just treat the template as scaffolding—extend it with your own security layers and scaling logic.

Unity MCP Template

mcp-template-ezgif com-resize

This is a simple example project demonstrating interaction between a TypeScript-b ased MCP server and Unity. You can build and configure your own tools to expand and develop further.

Create more tools your own!

Quick Start

unity-mcp-sample is a Unity example project. To minimize version-related issues and ensure compatibility with legacy versions, it does not use packages like NewtonsoftJSON. Additionally, the EditorWindow is implemented using IMGUI. The MCP can be managed through the UnityMCP-ShowWindow at the top.

Build MCP Server

within the unity-mcp-server

npm install
npm run build

Add MCP in Claude Desktop

Open Claude Desktop Settings, and Developer-Edit Config

{
    "mcpServers": {
      "unity-mcp": {
        "command": "node",
        "args":["F:/unity-mcp-template/unity-mcp-server/dist/index.js"]
      }
    }
  }

Create your own tools!

Both input data structure should be same.

Unity
