network_security_scan

THE RISK

High Risk

Network security scanning involves actively probing hosts, ports, and services on a network. This is an Execute-category action because it triggers external operations (sending packets, probing endpoints) whose effects depend on arguments (targets, scan types).

From the tool's definition 'Perform network security scanning and analysis' — actively executes network scans against targets

Documented attack patterns abuse exactly the kind of access network_security_scan gives an agent:

HOW TO CONTROL NETWORK_SECURITY_SCAN

PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Windows, and nothing reaches the server without passing your rules. This is the rule we recommend for network_security_scan:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "network_security_scan": {
      "limits": [
        {
          "counter": "network_security_scan_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

network_security_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.

Create a free account and register Mcp Windows — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

What does the network_security_scan tool do? +

Perform network security scanning and analysis. It is categorised as a Execute tool in the Mcp Windows MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on network_security_scan? +

Register the Mcp Windows MCP server in PolicyLayer and add a rule for network_security_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 Mcp Windows. Nothing to install.

What risk level is network_security_scan? +

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

Can I rate-limit network_security_scan? +

Yes. Add a rate_limit block to the network_security_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.

How do I block network_security_scan completely? +

Set action: deny in the PolicyLayer policy for network_security_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.

What MCP server provides network_security_scan? +

network_security_scan is provided by the Mcp Windows MCP server (mukul975/mcp-windows-automation). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Mcp Windows tool call.
