Proposed Implementation

[strawgate]

I went to look at implementing this -- the python sdk does not have the types to implement this yet but there is an open PR here modelcontextprotocol/python-sdk#685

looks like that above PR was merged (jun 26, is in mcp 1.15.0) - could this issue be reassessed?
