OpenAI Enables Richer Agent Context With Annotation Controls and WebMCP Integration

OpenAI announced that annotations paired with WebMCP now give AI agents significantly richer context to understand and act on user selections within ChatGPT's browser. The combination of these two technologies—annotations extensibility and the WebMCP web standard—allows developers to embed custom controls, metadata, and visual previews directly into agent interactions, streamlining workflows that previously required agents to interpret DOM elements or form fields blindly.
