[Feature Request] Support for Streamable HTTP in Python SDK

[Geqiandipan]

Hello,​

I'm currently working on a project that relies heavily on the Python SDK for interacting with MCP servers. The recent addition of Streamable HTTP support in the TypeScript SDK (version 1.10.0) has been a significant enhancement, allowing for more efficient and scalable communication.​

However, the lack of Streamable HTTP support in the Python SDK has been a limiting factor for our development. Implementing this feature would greatly benefit the Python developer community and align the SDK's capabilities with its TypeScript counterpart.​

I kindly request the addition of Streamable HTTP support in the Python SDK. If there's an existing roadmap or if this feature is already under development, please let me know. I'd be more than willing to contribute or assist in any way possible.​

Thank you for your consideration.

If we're looking for a client implementation to test against, this is the PR for the inspector to support Streamable HTTP. It's getting close.

Also, the spec really makes this simpler than before for HTTP servers. Here's a view that works for django without the python-sdk at all:
