MCP still feels so early. It's getting better - we went from "set up `npx` on your system and edit this JSON file in an obscure directory" to "set the name and URL of your MCP server" in claude.ai. But you're right, even knowing how to find a URL for the MCP server is a tall order for most.
I wonder what the optimal form factor is. Like what if your AI could /suggest/ connecting with some service? Like your AI is browsing a site and can discover the "official" MCP server (like via llms.txt). It then shows a prompt to the user - "can I access your data via X provider?". you click "yes", then it does the OAuth redirect and can immediately access the necessary tools. Also being able to give specific permissions via the OAuth flow would be really nice.
