I love that MCP servers are rediscovering the old idea of public web APIs mash-ups from the early days of Web 2.0. Of course we don't need any icky XML with its namespace and schemas. Just some vibe-heavy JSON.

Snark aside it's, autonomous agents were one of the more interesting justifications for web APIs back in the day. I don't think people necessarily envisioned LLMs but some sort of agent you could send off to grab data or book flights or whatever. Specs like WSDL do what MCP does today letting the autonomous system figure out how to use a service.

Oh well, schemas and the ability to do browser-native style transforms were lame! Lets transition to YAML so no one can say "no" to Norway.
