WHAT IT DOES

What webScan does on Linux Network Scanner MCP Server

AI agents invoke webScan 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 webScan needs a policy

While the tool description is empty (lowering confidence), the server context and sibling tools strongly indicate this tool performs active web scanning operations against targets. The server is explicitly designed for security scanning/vulnerability assessment, and sibling tools like 'dirbScan' (directory brute-forcing), 'exploitScan', and 'ftpBruteForce' indicate offensive security capabilities.

From the tool's definition Tool name 'webScan' on a server described as providing 'network security scanning and vulnerability assessment using Linux tools like nmap' alongside sibling tools like 'exploitScan', 'dirbScan', 'ftpBruteForce', and 'cmd'
