Implement SEP-1442: Make MCP Stateless #1058
Description
This is a tracking issue for implementation of SEP-1442.
Summary
This SEP focuses on enhancing MCP's ability to scale horizontally and operate in stateless or near-stateless modes. The TypeScript SDK needs to introduce patterns and protocol enhancements that allow servers to operate with minimal or no session state, enable seamless request distribution across multiple server instances, improve session handling mechanisms, optimize server startup performance, and provide guidelines for implementing stateless server architectures to support production deployments requiring high availability and horizontal scaling.
