List all media files that have been downloaded for a chat.
AI agents call telegram_list_media to retrieve information from Telegram MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays information about already-downloaded media files. It performs no data modification, deletion, execution, or financial operations. The blast radius of misuse is minimal—an agent could only enumerate media metadata it already has access to locally. Classification as Read is appropriate.
From the tool's definition Tool description states 'List all media files that have been downloaded' - a query/retrieval operation with no modifications or side effects. The name 'list_media' and action of listing/enumerating previously downloaded files are purely informational.
