AI agents call get_instagram_post to retrieve information from Media without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Attacks that exploit this kind of access
Fetch an Instagram post or reel by URL. Downloads ALL media (carousel images, videos) to a local folder with a unique ID.
