Stateless MCP: Inside the 2026 Transport Spec

Most MCP servers in production today are stateful- each client session is pinned to one server instance.

That works on a single node. Add a load balancer and scale horizontally, and sessions start breaking: Kubernetes routes a request to the wrong pod, a Fargate deployment rolls and drops active connections, and NGINX or AWS ALB need special configuration just to keep the server reachable.

The 2026 spec release candidate, locked May 21, fixes this at the transport layer through three SEPs.
- SEP-1442 removes the mandatory init handshake so negotiation folds into the first request.
- SEP-2322 makes elicitation stateless.
- SEP-2243 mirrors routing data into HTTP headers so load balancers can route without parsing the payload.

This session covers what each SEP changes, what breaks in the server you run today, and what to refactor before the spec ships. I'll also show how we externalize session state at Mem0, so a stateless server keeps the memory and context a real agent needs.

You'll leave with a migration checklist and an architecture for stateless-first MCP.

AGNTcon + MCPcon Japan🇯🇵 :)

I'll be speaking at AGNTcon + MCPcon Japan '' today!

Again, I forgot to share this, but yesss let's go!! I'll be talking about: Stateless MCPs- The 2026 Transport Spec

One of the biggest update was making MCP stateless. Going to share the related changes and some ways of migration

Second time in Japan in like 6 months~~

And an all nighter again TT
It's been 3-4 days of all nighters now. Had 1.5L of coffee yesterday night so I hopefully I wont sleep atleast before the session haha

As usual writing this while rushing to the venueeee

p.s. the hotel manager saw me pull an all nighter sitting in the common area and got me coffee TT

pic- took rn!!

Sharing through some August updates and reflections

A lot has happened this month and since I am getting old (closing 22 soon), I have lost my ability to larp. Which I will def try, but here I go consolidating everything-

1/ Some recent updates:

- I'll be in Shanghai for AGNTcon + MCPcon China in the first week of September to talk about Auditing the MCP Supply Chain. China finally yayyy ''
- Speaking at AGNTcon + MCPcon Japan '' in the second week of September on Stateless MCP: Inside the 2026 Transport Spec
- Speaking at KCD Gujarat on Scaling LLM Inference on Kubernetes with KV-Cache-Aware Routing, September 19
- Recently became a Cursor Ambassador!
- Hosting a Cafe Cursor on August 29
- My talk Measuring Valkey Saturation With Active-Time and Eventloop Metrics in 9.1 got selected for ValkeyConf, so Prague'' in October if my visa works out in the limited time I have TT
- Finally started working on my personal website. Been confused about how to design it, but finally have some ideas.
- Mem0 has been fun, currently working on integrations.
- Joined a Chinese language learning school. Online for now, but gonna start getting serious about it.
- Exploring DeepSeek Harness and Cursor Origin. Such interesting launches with so much engineering/research content.

2/ Some reflections:

a. It's finally been a year since I started my corporate journey (last Aug). Though I was working in uni and all, let's not consider that. It's been a rewarding experience. I'm glad I locked in around June/July last year and I've seen huge changes since then.

b. It'll be one year at the end of September since I took my first flight ever, and it was a direct international one lol. Not sure how I hadn't travelled through air before. Solo travel has been extremely fun!!!! I've been to 8 countries in less than a year, with 2 upcoming. I've also been working during my travels, and it keeps me pretty fresh-minded.

c. I really took my health and body for granted :(
I'm not really smart by nature, so my usual way of coping has been putting in double the hours and sacrificing sleep. My body does not show any good signs for my age.

d. I'll be 23 soon FAHHHH. I wanted to do better before reaching unc status, but it's been okay. Not regretful at least. I'll keep figuring things out as I go.

__

3/ What's next:

- Take the last 2 months slower, focus mainly on Mem0 + recurring work and get my health on track
- Maybe a long-term stay somewhere (long = 2 months hehe)
- Pick up some non-AI creative thing
- Dig into AI research better
I have nothing figured out, im 'on the go' person

A funny thingy:

Was going to speak at KCD Hanoi ''(July end)'booked flights/hotel' got my visa 8 hours before the flight ' rushed Pune to Mumbai (6hrs) ' wasn't allowed to board because my middle name wasn't on the visa.

Surprisingly, Vietnam doesn't support corrections, so all gone. Was irritated, had some good food (10k+ cal), and all good.
