# OpenAI Apps SDK Announcement: How This Workshop's Materials Help You Instantly

OpenAI just announced Apps SDK—and if you have an MCP server that exposes HTML resources, you can plug it directly into ChatGPT. Plot twist: we already built exactly that.

*Workshop Repository:* https://github.com/adityaarunsinghal/agentic-ai-workshop-2025

## What You'll Learn

One day after OpenAI Dev Day, discover how the MCP server you've been building is already compatible with ChatGPT's new app marketplace. Sam Altman literally said: "Anyone with an MCP server that exposes HTML can sell an app experience."
