nikto · PenTest MCP Server MCP: Risk & Policy

WHAT IT DOES

What nikto does on PenTest MCP Server

AI agents invoke nikto to trigger actions in PenTest 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 nikto needs a policy

Nikto is a well-known web server vulnerability scanner that actively probes target servers by sending crafted HTTP requests to detect misconfigurations, outdated software, and vulnerabilities. This constitutes executing external operations against a target system. In a penetration testing context, misuse could involve scanning unauthorized targets, making severity high.
