OpenAI’s Apps SDK: A Developer’s Guide to Getting Started

SMRTR summary

OpenAI launched its Apps SDK to help ChatGPT access local information through developer-created apps that enhance conversations with visual experiences like carousels. The system relies on Model Context Protocol (MCP) servers that expose tools for ChatGPT to call and return structured data rendered inline within chat conversations. Developers must create action-focused tools with HTML templates that display in iframes, following strict discovery guidelines to ensure apps appear only when relevant to user requests.
