## Parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `cidr` | string | yes | CIDR notation (e.g. 192.168.1.0/24). |

Parameters from the server's own tool schema.

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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "cidr_calculate",
    "arguments": {
      "cidr": "<cidr>"
    }
  }
}
```

## Why cidr_calculate is rated Low

This tool retrieves derived information from CIDR input parameters without modifying any state, executing code, or affecting external systems. It is a pure computational utility that returns network metadata. Classified as Read with low severity due to minimal risk—misuse would only provide incorrect network planning information, not enable unauthorized access or damage.

From the tool's own definition: "Tool calculates and returns subnet details from CIDR notation input: 'network, broadcast, mask, host count'. No modification, deletion, or external execution occurs; it performs read-only mathematical computation."

## Use case

AI agents call cidr_calculate to retrieve information from UnClick without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches UnClick:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "cidr_calculate": {}
  }
}
```
