AI agents invoke nmap_comprehensive_scan to trigger actions in Wireshark 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 execute active network reconnaissance against external systems, potentially triggering security alerts, violating terms of service, or constituting unauthorized access attempts. The description is empty, lowering confidence, but the tool name strongly implies executing an nmap scan. This is an external operation whose effects depend on arguments (target IPs/hostnames).
From the tool's definition Tool name 'nmap_comprehensive_scan' implies running nmap network scanning tool, which executes active network probes against target hosts
Documented attack patterns abuse exactly the kind of access nmap_comprehensive_scan gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Wireshark MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for nmap_comprehensive_scan:
{
"version": "1",
"default": "deny",
"tools": {
"nmap_comprehensive_scan": {
"limits": [
{
"counter": "nmap_comprehensive_scan_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}nmap_comprehensive_scan stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

nmap_comprehensive_scan. It is categorised as a Execute tool in the Wireshark MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Wireshark MCP Server MCP server in PolicyLayer and add a rule for nmap_comprehensive_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 Wireshark MCP Server. Nothing to install.
nmap_comprehensive_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_comprehensive_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_comprehensive_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_comprehensive_scan is provided by the Wireshark MCP Server MCP server (mixelpixx/wireshark-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Wireshark MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
