The main difference in using skills and MCP servers are that MCP servers that are loaded when used are attached to every prompt you send to your AI. This is true no matter what you are using to program with. This uses Tokens!!! Skills are only attached to your prompt when they are used and the AI only loads them when it is needed. This saves Tokens!!! The nice thing with Antigravity 2 is there is a toggle next to each MCP Server to load or not load it. Which means you can setup many MCP Servers and turn them off and on without playing with JSON Code. (see images)

I'm currently working on a project called Antigravity Historical Archive which will allow me to see the history of every project and it's contents that I have ever created with Antigravity. It also uses memory banks that can be loaded with specific content from a project and the history is always viewable from a UI, even if the main project directory is deleted in order to save space. The workflow is all automated and projects that have been deleted can also be recovered from the UI if you ever want to add something to a project that you previously deleted. There are many more features but that is the short description. I would love to speak with others on the subject of AI because while I'm not new to IT, I feel like I'm kind of in a silo when it comes to AI.
