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/files

Client Implementation is being worked upon here: #416

I'll focus on server implementation. @jspahrsummers , can you please assign this issue to me?

@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:

It would be nice if somebody posts an update. Thanks.

PRs for Server and Client transport are out, some are still pending the reviews. Once the review is done we'll merge and do the release - hopefully later this week - early next week.

@DevonFulcher
Stateless Remote MCP support (#76)
64b3fef 
The current implementation of the Python SDK is stateful. There is work
underway to fix this:
modelcontextprotocol/python-sdk#443. However,
currently we need to eject from the MCP framework to use stateless
requests. This is to avoid issues described in this issue:
modelcontextprotocol/python-sdk#520, for
example. I tested this in Claude by listing and making a request to a
remote tool.

Since all the PRs have been merged, when will the Release with the changes happen? :) v1.7.1 does not seem to contain the streamable http changes..
