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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "router_prefix_list_list",
    "arguments": {}
  }
}
```

## Why router_prefix_list_list is rated Low

This tool retrieves and queries IPv4 prefix list data without side effects. It is purely informational, used for viewing route filtering configuration. No data is created, modified, deleted, or executed. It falls squarely into the Read category with low severity due to the limited blast radius of accessing routing configuration metadata.

From the tool's own definition: "Tool name contains 'list' and description states 'List all IPv4 prefix lists' with no modification or execution implied."

## Use case

AI agents call router_prefix_list_list to retrieve information from FortiOS 7 6 X MCP Server 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 FortiOS 7 6 X MCP Server:

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