O que é chatgpt-app-builder?

Esta skill, agora obsoleta, permitia a criação de aplicativos ChatGPT com widgets interativos usando o mcp-use e o OpenAI Apps SDK. Ela era voltada para desenvolvedores que desejavam construir aplicativos ChatGPT, servidores MCP com widgets, widgets React ou trabalhar com o Apps SDK. A skill fornecia configuração zero para desenvolvimento de widgets, com registro automático e hooks React integrados. O aplicativo era consumido simultaneamente por um humano e pelo LLM do ChatGPT, que colaboravam através do widget. Atualmente, a skill foi substituída por `mcp-app-builder`, que oferece funcionalidades equivalentes ou superiores. Recomenda-se fortemente migrar para a nova skill para garantir suporte contínuo e acesso às atualizações mais recentes.

Documentação

ChatGPT App Builder

Construa aplicativos ChatGPT com widgets interativos usando mcp-use. Desenvolvimento de widgets com configuração zero, registro automático e hooks React integrados.

O aplicativo é consumido por dois usuários ao mesmo tempo: o humano e o LLM do ChatGPT. Eles colaboram através do widget — o humano interage com ele, o LLM vê seu estado. O widget é sua superfície compartilhada.

Antes de Codificar

  • Esclareça o que construir → discover.md: ao iniciar um novo aplicativo, validar uma ideia ou escopar funcionalidades
  • Projete ferramentas e widgets → architecture.md: ao decidir o que precisa de IU vs. apenas ferramentas, projetar fluxos de UX

Configuração

  • Estrutura e execução → setup.md: ao criar um novo projeto, iniciar servidor de desenvolvimento, conectar-se ao ChatGPT/Claude

Implementação

  • Handlers do servidor + criação de widgets → server-and-widgets.md: ao escrever server.tool() com widgets, helper widget(), arquivos de widget React
  • Estado do widget e contexto do LLM → state-and-context.md: ao persistir estado, acionar LLM a partir do widget, gerenciar dados efêmeros vs. persistentes
  • Modos de exibição, tema, layout → ui-guidelines.md: ao adaptar para inline/tela cheia/PiP, lidar com tema, dispositivo, localidade
  • API de componentes → components-api.md: ao usar McpUseProvider, Image, ErrorBoundary, useWidget
  • CSP e metadados → csp-and-metadata.md: ao configurar domínios externos, metadados de protocolo duplo
  • Padrões avançados → widget-patterns.md: ao construir widgets complexos com chamadas de ferramenta, estado, temas

Referência Rápida

// Servidor
import { MCPServer, widget, text, object } from "mcp-use/server";
server.tool({ name: "...", schema: z.object({...}), widget: { name: "nome-do-widget" } },
  async (input) => widget({ props: {...}, output: text("...") })
);

// Widget (resources/widget-name.tsx)
import { McpUseProvider, useWidget, type WidgetMetadata } from "mcp-use/react";
export const widgetMetadata: WidgetMetadata = { description: "...", props: z.object({...}) };
export default function MyWidget() {
  const { props, isPending, callTool, sendFollowUpMessage, state, setState, theme } = useWidget();
  if (isPending) return <McpUseProvider autoSize><div>Carregando...</div></McpUseProvider>;
  return <McpUseProvider autoSize><div>{/* IU */}</div></McpUseProvider>;
}
