A new developer demo shows GPT-6 Astra using WebMCP to control a 3D anatomy atlas from a single natural-language instruction, including isolating structures, positioning views, navigating cross-sections and generating walkthroughs. The demonstration points to a broader shift in agentic software: web apps can expose structured controls so an AI system operates the application directly, rather than only interpreting pixels and clicking through a human interface.

What improves

An agent can call explicit atlas controls for structure isolation, camera position, cross-sections and walkthrough creation.

What still needs review

Medical education and clinical-adjacent uses still require verified data, human oversight and defenses against unsafe tool behavior.
