Question

Hi, I'm trying to develop a small MCP server that can send push notifications to the client (Opencode) without the client requesting them (a bit like SSE notifications). This is part of the latest versions of the MCP protocol 2025-11-26

I would like to know which version of the protocol is supported so i can specify it. I couldn't find this information anywhere.
