If you're in Elixir land, Hermes MCP[0] is a fantastic library for building out MCP clients/servers with both SSE/HTTP support. And will be quite robust given the scalability and fault tolerance of the BEAM.

ooh cool. Sadly I am far from Elixir land. MCP starting out as largely STDIO definitely has made things harder for server-side engineers. I expect this will sort itself out this year though.
