This is the right practice. Why put the burden on the server? It is the job of client to remember, not the server. Server is there to serve requests, not do the remembering. That is how http worked from the beginning and that is why it has been successful.
Excellent improvement. The server-side complexity required to handle sessions has been a large burden both on infrastructure and on educating teams on its characteristics.
I'd made the shift to HTTP/Stateless from MCP a few months ago. It's the right thing to do IMHO. Reliability up, problems down. TOON support is natural, if desired, etc.<p>My only question is how do you handle channels in the architecture now. From what I saw in Claude Code, shifting to a totally http world has some timeout issues if a server drops out and comes back. Because of that I'm stuck writing stubs for my internal use MCP, this is fine for me, but if you are cleaning up semantics: Understanding how we expect clients to act around failure would really help, the story.
Hey 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!
Great work! Any word on when to expect support across claude clients?
When will java sdk come out with latest changes from spec?
Thank you for your work! I was looking forward to the stateless update.

Thank you!<p>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?
Perfect. The actual tool calls are stateless anyway; when an LLM asks get_my_todos and then asks add_todo it’s not actually holding anything in RAM it’s just text going back into the context window (get_my_todos results) and then another tool call<p>And even on the server side statefulness is very iffy anyway. How long are you going to hold something in RAM from a client and how long will you hold the connection open
Are the HTTP headers for method/name etc even needed at this point and just use urls instead?<p>e.g. mymcpserver.com/tools/call?mcp-method=search
are they coming up with an alternative? i use them to monitor workflows that takes days and now i have to make some changes
