What netdiscover_scan does on Kali Security MCP
AI agents invoke netdiscover_scan to trigger actions in Kali Security MCP. 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 netdiscover_scan is rated High
Netdiscover is an active ARP reconnaissance tool that sends packets across a network to discover live hosts. In the context of a Kali security server integrating 193 penetration testing tools, this tool almost certainly executes active network scanning operations. Active scanning against networks without authorization is potentially illegal and intrusive.
From the tool's definition Tool name 'netdiscover_scan' on a Kali Linux penetration testing server; description is empty but name implies active network scanning/discovery

The rule that runs netdiscover_scan safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Kali Security MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For netdiscover_scan, this is the rule to start with:
netdiscover_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.
The button opens the PolicyLayer dashboard: create your workspace, connect Kali Security MCP, apply this rule, and every netdiscover_scan call is checked against it from then on.
Questions about netdiscover_scan
netdiscover_scan is a execute tool on the Kali Security MCP server. It is categorised as a Execute tool in the Kali Security MCP MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Kali Security MCP server in PolicyLayer and add a rule for netdiscover_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 Security MCP. Nothing to install.
netdiscover_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 netdiscover_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 netdiscover_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.
netdiscover_scan is provided by the Kali Security MCP server (seac-25/kali-security-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
