WHAT IT DOES

What smbScan does on Linux Network Scanner MCP Server

AI agents invoke smbScan 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 smbScan needs a policy

SMB scanning tools actively probe remote hosts for SMB (Server Message Block) vulnerabilities, shares, and credentials. The server context — which includes brute force, exploit, and direct command execution tools — strongly implies this tool performs active network reconnaissance against SMB services.

From the tool's definition Tool name 'smbScan' on a server providing 'network security scanning and vulnerability assessment using Linux tools like nmap' with sibling tools including exploitScan, ftpBruteForce, bettercapScan, and directCmd.
