AI agents call get-recycle-bin-media-referenced-by 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 queries and returns reference data about deleted media items in the recycle bin. It does not modify, delete, or execute anything; it is a read-only lookup to inform decisions before permanent deletion.
