WHAT IT DOES

What arvan_net_port_scan does on ArvanCloud MCP Server

AI agents invoke arvan_net_port_scan to trigger actions in ArvanCloud 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 arvan_net_port_scan is rated High

Port scanning actively probes a remote host by sending network packets to enumerate open/closed TCP ports. This is an active external operation (not merely a read of internal data), with significant blast radius: scanning unauthorized hosts is often illegal, can trigger security alerts, and could be used as a reconnaissance step before an attack.

RECOMMENDED RULE

The rule that runs arvan_net_port_scan safely

PolicyLayer is an MCP gateway: it sits between your AI agents and ArvanCloud MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For arvan_net_port_scan, this is the rule to start with:

arvan_net_port_scan Rate-limited

arvan_net_port_scan 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.
