OpenAI adds sidebars and MCP extensions to ChatGPT plugins
On October 7 the Developers team showed MCP-based ChatGPT extensions with fullscreen left-nav views, thread side panels, file handlers and config pages, built on the openai/mcp-extensions SDK.
Plugin antes era texto rolando no chat. A OpenAI acabou de dar barra lateral pra eles. Em 7 de outubro o time de Developers mostrou extensões do ChatGPT em cima de MCP: tela cheia na nav esquerda, painel ao lado do thread, handler de arquivo e página de config. Canva na sidebar, Figma com @ no desktop, Adobe abrindo Acrobat e Photoshop no browser. O SDK é o pacote openai/mcp-extensions em TypeScript e Python, com MCP Events pra terceiro empurrar notificação na sessão. Plugin de referência: Bits & Bolts no GitHub. MCP nasceu na Anthropic; a OpenAI adotar é a parte quieta. Web começa nos planos pagos: Plus, Pro, Business e Enterprise. Free e Go depois, sem data. Menção com @ no composer só no desktop macOS e Windows por enquanto. Prazo pra conta free ou marketplace pago é rumor. A doc oficial só fala que o acesso vai ampliar.
Plugins used to dump text into the chat stream. OpenAI just gave them a sidebar. On October 7 the Developers team showed ChatGPT extensions on MCP: fullscreen views from the left nav, thread side panels, file handlers, and config pages. Canva in the sidebar, Figma via @ on desktop, Adobe opening Acrobat and Photoshop assets in the browser. The SDK is the openai/mcp-extensions package for TypeScript and Python, plus MCP Events so third parties can push into an active session. Reference plugin is Bits & Bolts on GitHub. MCP started at Anthropic; OpenAI adopting it is the quiet part. Web access starts on paid tiers: Plus, Pro, Business, Enterprise. Free and Go come later, no firm date. Composer @ mentions are desktop only on macOS and Windows for now. Any timeline for free users or a paid marketplace is rumor. Official docs only say expanded access is coming soon.
