ChatGPT plugins gain interactive extensions and event-triggered automation
OpenAI opened the extension framework it uses for ChatGPT features, letting plugins add sidebar homes, interactive panels and file viewers. Plugin creation and discovery changed, Sites can host supported plugins, and ChatGPT added support for the proposed MCP Events specification so connected-app events can start automations.
Why it matters: Plugins can now persist in the interface and initiate work from external events, expanding the permission and prompt-injection boundary beyond user-started conversations.
