API Development
Simplifies the development of Model Context Protocol (MCP) servers and fullstack applications for ChatGPT and Claude.
The chatgpt-app-builder skill provides a comprehensive framework and standardized best practices for developing production-ready MCP servers. It guides developers through the entire lifecycle of building AI-enhanced applications, from automated project scaffolding and complex OAuth authentication setup to the creation of interactive React-based widgets. By enforcing specific architectural patterns, this skill ensures that MCP servers are secure, performant, and fully compatible with the mcp-use framework for use in ChatGPT and Claude environments.
