alt Hacker NewsHey folks - one of the Lead Maintainers for MCP. Happy that we got this release out the door today, this is an exciting change for those that wanted to roll out remove MCP servers into serverless hosts. There is, of course, more good stuff packed, so if you have questions or feedback - our team is here to help!

Thank you for your work! I was looking forward to the stateless update.
Great work! Any word on when to expect support across claude clients?

Thank you!
What’s the best practice for tools where the upstream API only supports basic auth (username/password) and there’s no OBO option? In my case the login returns a token that’s only valid for an hour, so the user has to re-auth after that. Do you stash the credentials on the MCP server and silently refresh, or is there a nicer pattern people are using?
Congrats at shipping the new specification!
Any new to share on file upload support? We have shipped a MCP server and it has been really frustrating to observe MCP clients fumbling around with base64-encodings, polluting their context window with binary data. SEP-1306 (Binary Mode Elicitation) was superseded by SEP-2356 (File input support for tools and elicitation), and that was in turn superseded by SEP-2631 (File Objects and Transfer) which is currently left in a draft state with little activity.
Allowing LLM-based agents to shuffle binary data around efficiently and reliably seems like a pretty big gap in the current specification, if you ask me!
