Unity MCP Template

Example Use Cases

• 1

  Control or create Unity Editor tools (e.g., create game objects or trigger editor actions) from an external MCP server.

• 2

  A reference implementation to integrate Claude Desktop with Unity via a TypeScript MCP server and test message passing.

• 3

  A lightweight, dependency-minimized Unity sample (no NewtonsoftJSON, IMGUI-based) to prototype editor integrations and custom toolchains.

Description

This repository provides a simple example project showing how a TypeScript MCP server can interact with a Unity project. It includes a Unity sample (unity-mcp-sample) with an IMGUI EditorWindow and a TypeScript MCP implementation you can build with npm. The project is intended as a starting point for developers to create custom Unity tools that communicate with Claude Desktop via MCP, and includes instructions for adding the MCP to Claude Desktop. A noted TODO is to revise the TCP structure (currently reversed client/server due to an SDK bug).
