WHAT IT DOES

What clear_expired_context_cache does on Obsidian Elite RAG MCP Server

AI agents call clear_expired_context_cache to permanently remove resources in Obsidian Elite RAG MCP Server, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why clear_expired_context_cache is rated Critical

Clearing cache entries is an irreversible deletion operation; once cache entries are removed they cannot be restored without re-indexing/re-processing. While 'expired' entries are targeted (suggesting lower blast radius than a full cache wipe), the action is still a deletion that cannot be undone, placing it in the Destructive category.

From the tool's definition 'Clear expired documentation cache entries' — the action permanently removes cache entries
