MCP is moving to a stateless transport model on July 28
The post says the MCP spec will get a major upgrade on July 28: a move to stateless MCP over streamable HTTP.
Key changes and benefits called out in the diagram and text:
- Each JSON-RPC request carries everything needed to be understood in isolation.
- No session state lives on the server.
- Servers can be fronted by a load balancer with horizontal scaling and ordinary round-robin routing.
- No sticky sessions or first-request handshake are required.
- The result should be higher reliability, better scalability, and simpler server code.
