Thanks for the PR!

I think we probably want to actually create a /draft alias, like /latest. This would make https://spec.modelcontextprotocol.io/draft a usable link (e.g., to send people), which is valuable.

Can you please update the PR to do that?

@jspahrsummers thank you, that makes sense. I added the alias: 8e98e65
