SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires aiohttp, fastapi, uvicorn, fastmcp, pydantic, @modelcontextprotocol/sdk, express, zod, react, mapbox-gl, and includes scripts (resource) and assets (resource) components.

What problem does it solve?

Building interactive ChatGPT applications with rich UI widgets can be complex, requiring expertise in both backend (MCP server) and frontend (React widgets) development, along with careful configuration for security and deployment. This skill automates the generation of this entire stack, eliminating manual setup and boilerplate code.

Core Features & Use Cases

  • Full-Stack App Generation: Automatically creates both Python/TypeScript MCP servers and React UI widgets.
  • Best Practices Included: Incorporates security (CORS, OAuth), validation, and deployment best practices.
  • Interactive UI: Supports various widget patterns like maps, charts, and forms for rich user experiences.
  • Use Case: Ask Claude to "Create an OpenAI app that finds coffee shops near me with a map" and get a complete, ready-to-deploy application with an interactive map widget.

Quick Start

Ask Claude to build an app:

"Create an OpenAI app that tracks my daily habits"

Or use the scaffolder script:

python scripts/scaffold_project.py my-new-app

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I build a complete ChatGPT app with a React UI and backend server?▼

Build interactive ChatGPT apps by creating both a backend MCP server (Python FastAPI or TypeScript Express) and frontend React widgets. This Skill automates full-stack generation, scaffolding, and configuration so you deploy a complete application without manual boilerplate setup.

What is an MCP server and why do I need one for OpenAI apps?▼

An MCP server is a backend that exposes tools and resources to Claude. For OpenAI apps, it bridges your business logic with Claude's interface, handling requests and returning structured data that React widgets render as interactive UIs.

Can I create custom React widgets that display in ChatGPT?▼

Yes. Create React widgets with the correct MIME type (text/html+skybridge) and metadata bridge via _meta.openai/outputTemplate. This Skill guides widget development, validation, and integration so your custom UI components render properly in ChatGPT.

Do I need to manually configure CORS and security for deployment?▼

No. This Skill includes built-in best practices for CORS, OAuth, and security validation. It generates production-ready configurations so you avoid common misconfigurations when deploying MCP servers and React widgets.

How do I get started building an OpenAI app from scratch?▼

Ask Claude to build an app (e.g., "Create an OpenAI app that finds coffee shops near me with a map") or use the scaffold_project.py script to generate a starter project. The Skill creates both backend and frontend code ready to test and deploy.

What frameworks and libraries does this support?▼

Build backends with FastAPI and FastMCP (Python) or Express and TypeScript. Create frontends with React. The Skill handles Pydantic validation, Zod schemas, and integrations like Mapbox for rich, interactive widgets.
