## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",

## Why masscan_high_speed is rated High

Masscan is an aggressive, high-speed port scanner capable of scanning the entire internet in minutes. Even without a description, the tool name combined with the server's offensive security context strongly implies it executes active network scanning against targets. Misuse could trigger legal consequences, disrupt networks, and expose attack surfaces.

From the tool's own definition: "Tool name 'masscan_high_speed' references Masscan, a well-known high-speed port scanner used for large-scale network reconnaissance and attack surface mapping."

Risk signals: Bulk/mass operation — affects multiple targets

## Use case

AI agents invoke masscan_high_speed to trigger actions in Hexstrike Ai. 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.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Hexstrike Ai:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "masscan_high_speed": {
      "limits": [
        {
          "counter": "masscan_high_speed_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
