Discussion Topic

I've been trying to understand some of the design decisions as part of MCP and found a it a bit hard to find references to the discussions / issues in which the protocol was updated.

Some example questions that seem to come up a lot and would be useful to have documented design choices on:

• What are "prompts" and how are the intended to be used. The protocol / docs do capture this but it'd be useful to see discussion and detailed design choices
• Why was a raw transport layer instead of standardizing on HTTP

Is this something I'm missing (perhaps it already exists and I didn't find it), or would it be useful to have a RFC registry for changes to the protocol?
