MCP Widget Patterns for OpenAI Apps SDK

Overview

Widgets are visual components that render inline with ChatGPT conversations. This skill catalogs proven widget patterns with implementation guidance for the OpenAI Apps SDK.

Display Modes

The Apps SDK supports four display modes, each suited to different use cases:

Mode	Use When	Example
Inline	Quick confirmations, simple data	Order confirmation card
Inline Carousel	Comparing similar items	Product search results
Fullscreen	Complex workflows, rich interaction	Document editor, maps
Picture-in-Picture	Persistent parallel activity	Video call, game

Inline Card Patterns

Simple Confirmation Card

Use for: Action confirmations, status updates, receipts

<div class="card">
    <div class="card-header">
        <span class="icon">✓</span>
        <span class="title">Booking Confirmed</span>
    </div>
    <div class="card-body">
        <div class="detail-row">
            <span class="label">Restaurant</span>
            <span class="value">Chez Pierre</span>
        </div>
        <div class="detail-row">
            <span class="label">Date</span>
