Control Unity Editor with Claude Code via MCP Server

This MCP server provides a robust framework for developers to programmatically control the Unity Editor using Claude Code. By establishing a TCP bridge, it enables seamless communication between your AI agent and the Unity environment, allowing for complex automation and custom tool development. This open-source solution is designed for efficiency and extensibility, offering a powerful way to integrate AI-driven workflows into your game development process.

What it Does

The MCP Server acts as an intermediary, translating commands generated by Claude Code into actions that the Unity Editor can execute. It exposes a comprehensive set of 98 pre-built tools that cover a wide range of editor functionalities, from scene manipulation and asset management to script execution and build processes. The server's architecture is optimized for performance and resource management, particularly through its token-optimized plugin system, ensuring efficient operation even with complex AI models.

Key Features

TCP Bridge: Enables reliable, low-latency communication between your AI agent and the Unity Editor.
98 Built-in Tools: A comprehensive library of commands for extensive editor control.
Token-Optimized Plugin System: Designed for efficient integration with AI models, minimizing token usage.
Open-Source: Full access to the source code for customization and community contributions.
MCP Protocol: Leverages the established MCP protocol for standardized interaction.

Who it's For

This tool is specifically for AI developers and Unity game developers looking to automate and enhance their workflows. It is ideal for those building AI agents that require direct interaction with the Unity Editor for tasks such as:

Automated asset generation and placement.
Procedural content creation.
AI-driven testing and debugging.
Custom editor tooling development.
Integrating large language models for creative development assistance.

If you are working on advanced AI integrations within Unity, this MCP server offers a powerful and flexible solution.
