This reminds me of a time when 'API' has become a hot term. Every company would ship an API. I think Facebook, Instagram, Twitter, Reddit, and I think even Google at some point had nice public APIs. This was the era of RSS and semantic web as well... until most realized there's no easy way to serve ads or control UX, making APIs great for customers but bad for business (unless the API is your product of course)
Given this, I'm not sure what business purpose there is to ship an MCP API like this, aside from goodwill and exposure.
