WHAT IT DOES

What arvan_purge_cache does on ArvanCloud MCP Server

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

RISK

Why arvan_purge_cache is rated Critical

Purging cache is an irreversible operation that permanently removes all cached content for a domain. This cannot be undone — the cache must be rebuilt organically through new requests. Misuse could cause significant performance degradation (cache stampede, origin overload) for an entire domain's traffic.
