Mcp StreamableHttp JAVA SDK When is expected to be supported improve

[wdhzwdx]

Please do a quick search on GitHub issues first, the feature you are about to request might have already been requested.

Expected Behavior

Expected MCP to support streamable HTTP

Current Behavior

At present, only MCP Spring Webflux has a WebClient Streamable HttpTransport, and there is no corresponding server Transport

Context

Some interfaces may take a long time, so I hope to stream them for better results. I have also checked that the SDK for Python supports it, but our project is entirely in Java and we cannot switch to Python. Therefore, I would like to ask when Java is expected to improve its support for streamable HTTP

Custom "/mcp" interface, long connection SSE consumes too much resources. Take a look at my sample code

But I need SSE, including server and client implementation. Similar to the Python effect shown in the figure below, streamable HTTP supports SSE

The servelt response can be ouput in a stream format

You can also implement SSE in the interface
