MCP just had its biggest release since launch.
On July 28, the maintainers shipped the 2026-07-28 spec, and it changes how MCP servers work at a pretty fundamental level. The handshake is gone. Sessions are gone. Three long-standing features are deprecated.
The maintainers themselves called it the most substantial change since authorization was added. Their words, not mine.
Sounds scary. But it actually makes MCP servers much easier to deploy. And what am I here for? I'm here to help you build and deploy one.
Your MCP server is now just a regular stateless HTTP service. Round-robin load balancing, autoscaling, and caching all work. No sticky sessions or shared session state.
