I really hate to be the curmudgeon here but won't foundation models end up having their own AI workflows like the GPT store but with MCP?
I could really envision saving an 'AI Workflow' template with integrated MCP clients that will balloon once adoption is reached. Right now adoption is low so its not a priority for them, once it is, they will tack it on.
I really wish this the best of luck its a great concept, but surely you must be thinking ahead to plan for this situation.
