The latest expansion of the company's AI ecosystem enables real-time updates and automations to be triggered by external servers. Developers can now deploy MCP servers and plugin extensions directly on ChatGPT Sites, allowing the creation of tools that operate as either pinned sidebar experiences or fullscreen applications. This update includes support for the MCP Events specification, which permits servers to push notifications to the chatbot to initiate automated workflows.

OpenAI is migrating its own first-party tools, such as meetings and code review, to this plugin architecture to standardize how features are delivered. This follows the recent release of a Plugin Creator tool and interactive file viewers. Third-party developers have already begun deploying these capabilities, with Shopify introducing a pinnable plugin and MagicPath launching a sidebar-based canvas for direct file access within the chat interface.
