amass_scan · Kali Linux MCP Server MCP: Risk & Policy

WHAT IT DOES

What amass_scan does on Kali Linux MCP Server

AI agents invoke amass_scan to trigger actions in Kali Linux 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 amass_scan needs a policy

Amass is a well-known OSINT and network enumeration tool used for attack surface mapping and subdomain discovery. While the description is empty, the tool name and server context strongly suggest it performs active or passive reconnaissance against external targets. On a pentest server alongside exploitation and attack tools, misuse could expose target infrastructure details or be used as a precursor to attacks.

From the tool's definition Tool name 'amass_scan' on a Kali Linux penetration testing server with sibling tools including network scanners, exploitation frameworks, and attack tools.
