WHAT IT DOES

What flush_server_dns does on Unofficial FortiMonitor MCP Server

AI agents invoke flush_server_dns to trigger actions in Unofficial FortiMonitor MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why flush_server_dns is rated High

Flushing DNS cache is an operational action that triggers an external operation on a server (clearing its DNS cache), which can affect name resolution behavior. It's not a simple read, nor does it permanently delete data, but it executes a system-level operation with potential service impact if misused.

RECOMMENDED RULE

The rule that runs flush_server_dns safely

flush_server_dns Rate-limited

flush_server_dns stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
