AI agents call get_cache_stats to retrieve information from Facebook Ads Library MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
get_cache_stats retrieves and reports on cache metadata (status, storage usage, file counts) without modifying, creating, or deleting any data. This is a classic Read operation - it queries system state for monitoring purposes. No execution of external code, destructive actions, or financial operations are involved.
From the tool's definition Tool description states it is 'REQUIRED for checking media cache status and storage usage' and 'Use this tool when users ask about cache statistics, storage space used by cached media...'.
