Multiple transports in one server? #124
Description
Can one use this framework to instantiate a server that listens not only on one transport, but on multiple? Like, I'm building an MCP server and I'd like it to be generally useful for people however they want to run it. I can see use cases for both stdio and HTTP. There are also some clients that still don't support HTTP so adding SSE in there would provide a fallback. Is this just-listen-on-all-transports model currently possible with mcp-framework? I can do it with the typescript-sdk if necessary, but otherwise this framework looks nice.
