MCP Protocol Standard SEP-2575: Shifting to Stateless Architecture for Better Scalability
kleffew94 · x · 2026-08-11
The Model Context Protocol (MCP) has introduced proposal SEP-2575, now in Final status, aiming to transition the MCP protocol to a truly stateless architecture by default.
- The Problem: Current MCP relies on initialization handshakes and persistent session states, making it difficult to scale behind standard load balancers due to the coupling of client sessions to specific server instances.
- The Solution: It proposes a "pay as you go" model for complexity, offering simple, stateless features by default and only introducing state overhead when necessary, thereby enhancing simplicity, scalability, and reliability.
