With a stateless makeover, new MCP spec targets enterprise scale
Plus, a new policy for the AI protocol ensures features aren’t removed suddenly.
TL;DR
- The Model Context Protocol (MCP) core is now stateless, moving from a stateful to a request/response protocol.
- This statelessness aims to address scalability barriers and improve reliability for MCP servers.
- Additional updates include Multi Round-Trip Requests, header-based routing, cacheable list results, authorization hardening, and a formal extensions framework.
- A new deprecation policy provides at least 12 months' notice before feature removal, excluding critical security updates.
- MCP is managed by the Agentic AI Foundation (AAIF) under the Linux Foundation, with contributions from major tech companies like Anthropic, OpenAI, Google, Microsoft, and Amazon.
