  The new MCP spec just dropped! 🎉
  
  There's too many new things to get into everything, but there are two big changes I am most excited about 👀
  
  📝 Client ID Metadata Documents (CIMD) - a simpler way to manage client registrations, clients describe themselves with a URL they control
  🔐 Enterprise-Managed Authorization extension (aka Cross App Access) - eliminate the OAuth redirect and get tokens for an MCP server by requesting them from the enterprise IdP
  
  It's been great working on this with folks like Den Delimarsky, Paul Carleton, David Soria Parra, Nick Cooper, Tyler Leonhardt, and more!
