Sorry, I think that's just the nav on those docs being confusing (particularly on mobile). You can see the spec here: https://spec.modelcontextprotocol.io/specification/
Ahh thanks! I was gonna say it's broken, but I now see that you're supposed to notice the sidebar changed and select one of the child pages. Would def recommend changing the sidebar link to that path instead of the index -- I would do it myself but couldn't find the sidebar in your doc repos within 5 minutes of looking.
Thanks for your hard work! "LSP for LLMs" is a fucking awesome idea
