Handler vs unity-mcp
Handler: Handler is an open-source A2A protocol client for your terminal. It provides a TUI and CLI to send messages, manage tasks, and inspect agent cards. An included MCP server lets AI assistants communicate with A2A agents.; unity-mcp: MCP for Unity integrates AI assistants like Claude and VS Code Copilot with the Unity Editor using the Model Context Protocol. This allows developers to use Large Language Models to manage assets, control scenes, edit scripts, and automate various tasks within Unity, streamlining game development workflows.

When to choose:
- You develop games in Unity and want AI assistants (Claude, Cursor) to manage assets, inspect hierarchy, edit C# scripts, and run Editor commands via MCP.
- You want to automate scene setup, prefab creation, and repetitive Unity Editor tasks using natural language.
When to skip:
- You use Unreal Engine or Godot; unity-mcp connects strictly to the Unity Editor.
- You only write gameplay C# logic outside of Unity and do not need Editor-level RPC integration.
