Rebuild MCP servers stateless ahead of the 2026-07-28 spec: no session store, round-robin LB, cacheable tools/list
The 2026-07-28 MCP release candidate removes the protocol-level session model entirely — every request now carries its own protocol version, client info, and capabilities, so a server that needed sticky sessions and a shared session store can run behind a plain round-robin load balancer and route on an Mcp-Method header. This is the largest MCP revision since launch and is a breaking change for production servers. Actionable: make each request self-contained and let clients cache tools/list before the final spec ships July 28.
