This is no different from a web app though, there’s no obvious need to reinvent the wheel. We know how to do this very very well: the underlying TCP connection remains active, we multiplex requests, and cookies bridge the gap for multi-request context. Every language has great client & server support for that. Instead we ended up with a protocol that fights with load balancers and can in most cases not just be chucked into say an existing Express/FastAPI app. That makes everything harder (& cynically, it creates room for providers like Cloudflare to create black box tooling & advertise it as _the_ way to deploy a remote MCP server)
