I haven't dug too deeply into MCP yet so I may very well be wrong here, but it feels like get another attempt to paper over the fact that we abandoned REST APIs nearly 20 years ago. XML is ugly and building APIs that describe both the data and available actions is tough. Instead we picked JSON RPCs that we still call REST, and we inevitably run into situations like Alexa or LLMs where we want a machine to understand what actions are supported in an API and what the data schema is.
