Unfortunately, MCP is not HATEOAS. It doesn't need to be, because it's not web-like. I wish it were.

HATEOAS is great for web-like structures because in each response it not only includes the content, but also all actions the client can take (usually via links). This is critical for architectures without built-in structure — unlike Gopher which has menus and FTP and Telnet which have stateful connections — because otherwise a client arriving at some random place has no indication on what to do next. MCP tackles this by providing a stateful connection (similar to FTP) and is now moving toward static entry points similar to Gopher menus.

I specifically wrote about why pure HATEOAS should come back instead of MCP: https://www.ondr.sh/blog/ai-web
