WHAT IT DOES

What scan_open_ports does on Mcp Windows

AI agents invoke scan_open_ports to trigger actions in Mcp Windows. 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 scan_open_ports is rated High

Port scanning involves executing active network probes against a target host. This is not a passive read; it sends network packets to enumerate open ports, which constitutes an external operation with potential legal and security implications. Misuse could target unauthorized systems, trigger intrusion detection systems, or be used as reconnaissance for attacks.

From the tool's definition 'Scan for open ports on a target host' — actively probes a remote host's network ports

RECOMMENDED RULE

The rule that runs scan_open_ports safely

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

scan_open_ports Rate-limited

scan_open_ports 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.
