I've started building MCP servers for some of my own projects as well. For example, I built one for a VIN decoder website so AI assistants can look up vehicle information directly instead of requiring users to switch back and forth between a chat and a browser. For me, that's the biggest appeal of MCP. It's not just another API wrapper—it makes existing tools much easier to use from within an AI workflow. The less context switching users have to do, the better the experience feels. The move toward a more stateless design also makes a lot of sense. Simpler deployment, easier horizontal scaling, and fewer session-management headaches are all welcome improvements for anyone running these services in production.
