Implement Streamable HTTP transport #443
Description
Activity
We need this too, please. We are interested in HTTP request / response use case: modelcontextprotocol/modelcontextprotocol#206 (comment). We have a turn based agent framework that cannot maintain long term TCP connection and is request / response based.
I'm picking this up. Will share a PR by the weekend.
Specification PR is merged: https://github.com/modelcontextprotocol/modelcontextprotocol/pull/206/files
Server-side support has been added in TypeScript SDK: https://github.com/modelcontextprotocol/typescript-sdk/pull/266/filesClient Implementation is being worked upon here: #416
I'll focus on server implementation. @jspahrsummers , can you please assign this issue to me?
Reacted by Michael Scully, bjb2010, (Frank) Yu Cheng Gu, Alex Pryiomka, haotianliu, Cao Yu, Raghav Dua, majdsalman2, Bhavesh, Juan Abia and 2 more@karanb192 I'm planning to work on this in the next couple of days, just wrapping up the implementation for the TypeScript SDK right now.
I'd appreciate any comments and review on Python SDK implementation PR once it's up.

There is a PR for the server part here. It seems to be missing just formatting & type checks. I haven't had a chance to test the PR out myself yet.See the following PR's:
