WHAT IT DOES

What zmapScan does on Linux Network Scanner MCP Server

AI agents invoke zmapScan to trigger actions in Linux Network Scanner 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.

WHY IT NEEDS A POLICY

Why zmapScan needs a policy

ZMap is a fast network scanner capable of scanning entire IP ranges, commonly used in security research and penetration testing. Despite an empty description, the tool name strongly implies execution of the ZMap scanning utility, which actively probes external network hosts.

From the tool's definition Tool name 'zmapScan' on a server described as providing 'network security scanning and vulnerability assessment using Linux tools'. Sibling tools include nmap-style scanners, exploit tools, brute force tools, and direct command execution.
