If OpenAI has set the API standard more or less without even trying just by offering one of the most straightforward ways of interacting with LLMs via http. To the point that they got stuck with this legacy thing now that they and many others keeps reasoning traces private on their servers, which actually hinders future adoption. If they had forced their function calling and structured output API standards just a bit more in response to MCP, they probably could have smothered it in the crib. If this part was standardised more, MCP would offer hardly any extra benefit.
