gm-exec vs unity-mcp
gm-exec: gm-exec is a code execution tool for MCP clients and CLI, supporting multiple languages (JS/TS, Python, Go, Rust, C, C++, Deno, Java, bash). It runs on Bun with PM2-managed process isolation and offers background execution with a 15-second timeout limit.; 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.

Execute code snippets in different languages from CLI

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.
