MCP's newest spec removes the requirement that every request return to the same server — the same architectural move that let HTTP scale. It is a real step forward, but state, identity, and execution continuity now have to be bound explicitly in the application and platform layer instead of relying on protocol-managed sessions.

Notes from KubeCon EU 2026 in Amsterdam and Agentics Day: MCP is converging as the enterprise protocol for agent-to-system connectivity, agent gateways are emerging as the coordination layer for AI traffic, and OpenTelemetry is becoming the shared observability standard. The bar everyone kept coming back to: the effort to supervise agents must be lower than the work they take off the table.
