What I really want from Anthropic, Gemini, and ChatGPT is for users to be able to log in with them, using their tokens. Then you can have open/free apps that don’t require the developer to track usage or burn through tons of tokens to demonstrate value. Most users aren’t going to manage API keys, know that that even means, or accept the friction.
I assume the fall off there will be 99% of users though, the way it works today.
But this theoretically allows multiple applications to plugin into ChatGPT/claude/gemini and work together.
If someone adds zillow and… vanguard, your LLM can call both through mcp and help you plan a home buy
