Scan network hosts and ports using nmap. Scan types: basic, fast, intense, vuln, service. WARNING: Only scan authorized targets.
AI agents invoke nmap_scan to trigger actions in Kali Linux Security Tools 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.
Nmap scans actively probe remote systems by sending network packets, which constitutes external operation execution rather than a passive read. Misuse by an AI agent could result in unauthorized reconnaissance of third-party systems, triggering intrusion detection systems, violating computer fraud laws, or facilitating further attacks. The 'intense' and 'vuln' scan types are particularly aggressive.
From the tool's definition 'Scan network hosts and ports using nmap' with scan types including 'intense' and 'vuln' — actively sends network packets to external targets; part of a Kali Linux penetration testing server
Attacks that exploit this kind of access
Scan network hosts and ports using nmap. Scan types: basic, fast, intense, vuln, service. WARNING: Only scan authorized targets. It is categorised as a Execute tool in the Kali Linux Security Tools MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Kali Linux Security Tools MCP Server MCP server in PolicyLayer and add a rule for nmap_scan: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Kali Linux Security Tools MCP Server. Nothing to install.
nmap_scan is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the nmap_scan rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for nmap_scan. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
nmap_scan is provided by the Kali Linux Security Tools MCP Server MCP server (jesseeikeland/kali-linux-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
