The Model Context Protocol (MCP) is transitioning to a stateless architecture to improve scalability and routing. Previously, MCP relied on stateful, long-lived connections that required requests to hit the same server for a session to succeed. This new stateless mode, enabled by `stateless_http=True` in the Python SDK, allows any server to handle requests independently, eliminating the need for sticky sessions and simplifying load balancing in multi-replica deployments. A demonstration using Kubernetes shows that the stateless approach successfully handles requests across multiple pods, unlike the older stateful method which failed significantly when scaled. AI
IMPACT Enables more robust and scalable deployments of AI models by improving the underlying communication protocol.
