The Model Context Protocol (MCP) has transitioned to a stateless design as of July 28th, significantly altering how gateways manage client interactions. Previously, gateways relied on client-held session IDs to route requests and track backend capabilities. The new specification eliminates session management, requiring each request to carry its own protocol version, client information, and capabilities within the request metadata. Projects like Agent Router are adapting by implementing stateless fan-out for discovery and list requests, ensuring gateways can still present multiple backend MCP servers as a single interface without maintaining session state.
