Apps SDK Examples Gallery FAQs

Name: Apps SDK Examples Gallery
Author: openai

Question 1

What is the Apps SDK Examples Gallery?

Accepted Answer

The Apps SDK Examples Gallery is a collection of example UI components (widgets) and Model Context Protocol (MCP) servers designed to demonstrate building rich, interactive applications for ChatGPT. It serves as a starting point and inspiration for developers.

Question 2

What is the Model Context Protocol (MCP) and why is it important?

Accepted Answer

MCP is an open specification for connecting large language model clients (like ChatGPT) to external tools, data, and user interfaces. It standardizes the wire format, authentication, and metadata, allowing ChatGPT to reason about and integrate your custom connectors and return rich UI components.

Question 3

What programming languages are used for the example MCP servers?

Accepted Answer

The gallery provides example MCP server implementations in both Node.js (using the official TypeScript SDK) and Python, offering flexibility for developers to build their applications.

Question 4

How do these examples help in creating rich UI components for ChatGPT?

Accepted Answer

The examples illustrate how MCP servers can return rich UI components (widgets) using `_meta.openai/outputTemplate` metadata alongside structured content. This allows the Apps SDK client (ChatGPT) to render interactive interfaces directly within assistant messages.

Question 5

Can I test these examples with ChatGPT locally?

Accepted Answer

Yes, you can run the MCP servers locally and use tools like ngrok to expose them to the internet. Then, enable developer mode in ChatGPT and add your local server URL in Settings > Connectors to test your apps directly in conversations.
