The next generation of MCP
The MCP 2026-07-28 specification was released, transitioning the Model Context Protocol from stateful to stateless. This removes the requirement for persistent connections between clients and servers.
Why it matters
Developers can now host servers on simpler, lower-cost infrastructure like Cloudflare Workers. This reduces the operational overhead and cost of maintaining AI agent connections.
The details
- Multi Round-Trip Requests now handle cases where servers need more user information.
- New HTTP headers allow network gateways to manage MCP requests without parsing JSON.
- A formal feature lifecycle classifies protocol features as Active, Deprecated, or Removed.
