Occams Razor spares none.
Everything will go to the simplest and most convenient, often both, despite the resistance of the complexity lovers.
Sorry MCP, you are not as simple as CLI/skill/combination, and no, you are not more secure just because you are buried under 3 level of spaghetti. There are no reason for you to exist, just like Copilot. I don't just wish, but know you'll go into obscurity like IE6.
i use mcp for security. you can have an airgapped agent that can still call online tools. for example, web search.
however it can't get infected because there is no internet access.
the worst you can do is put your secrets in the web search box
That's "Worse is better" rather than "Occam's razor".
A webpage with a form should be good enough.
Thanks for the 3x context usages because it need to follow the installation steps. and extra credit for the auth token leaks because it is sent in every call as context.
