WHAT IT DOES

What securityScan does on Linux Network Scanner MCP Server

AI agents invoke securityScan to trigger actions in Linux Network Scanner 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 securityScan needs a policy

The tool name 'securityScan' combined with the server context (offensive security tools, exploit scanning, brute force tools, raw command execution via 'cmd'/'directCmd') strongly implies this tool executes active network security scans against target systems. Even without a description, the server context makes it clear this runs external scanning operations with potentially wide blast radius.

From the tool's definition Tool is part of a server explicitly described as providing 'network security scanning and vulnerability assessment using Linux tools like nmap' with sibling tools like 'exploitScan', 'ftpBruteForce', 'aircrackScan', 'bettercapScan', and 'directCmd' — all…

Verdict

securityScan Rate-limited

securityScan 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.

FAQ

Questions about securityScan

What does the securityScan tool do? +

securityScan. It is categorised as a Execute tool in the Linux Network Scanner MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on securityScan? +

Register the Linux Network Scanner MCP Server MCP server in PolicyLayer and add a rule for securityScan: 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 Linux Network Scanner MCP Server. Nothing to install.

What risk level is securityScan? +

securityScan is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit securityScan? +

Yes. Add a rate_limit block to the securityScan 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.

How do I block securityScan completely? +

Set action: deny in the PolicyLayer policy for securityScan. 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.

What MCP server provides securityScan? +

securityScan is provided by the Linux Network Scanner MCP Server MCP server (nibesh0/netsecmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
