How to Build Your Own MCP Server and Publish Your ChatGPT App with Supabase Auth and DigitalOcean
SMRTR summary
A new breed of app is quietly taking shape, and it doesn't live on your phone or in a browser tab. It lives inside AI chat itself. Developers are now building what are called MCP servers, or Model Context Protocol servers, which connect AI assistants like ChatGPT to real tools, databases, and custom interfaces.
Think of it as giving your AI a nervous system. Instead of just answering questions, it can now save your data, check live information, and render interactive widgets directly inside the chat window.
A detailed new tutorial walks developers through building one from scratch, using Node.js, the Supabase database and authentication platform, and DigitalOcean for deployment. The end result is a fully functional to-do app that runs inside ChatGPT, complete with user login and a visual interface.
And once built, developers can submit their creation to ChatGPT's official app directory, potentially putting it in front of millions of users. It's a glimpse at what the next generation of software might actually look like.
