AI agents call get-media-are-referenced to retrieve information from Mcp Dev without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves reference information about media items without creating, modifying, deleting, or executing any operations. It is a read-only verification check designed to inform the user before they take other actions. While the description mentions it is useful before deletion, the tool itself performs no destructive action.
From the tool's definition Tool description states 'Check if media items are referenced' and 'verify if specific media items are being referenced' - these are query/verification operations with no modifications or deletions performed by the tool itself.
