- Homepage: https://github.com/jmpijll/fortimanager-mcp
- Risk category: Read (Low risk)
- Registry record: grade F, identity unverified

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

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

## Why list_device_groups is rated Low

This tool queries and returns information about device groups without creating, modifying, or deleting any data. It is a straightforward read operation with minimal risk. The low severity reflects that listing device groups exposes organizational structure information but does not enable harmful actions by itself.

From the tool's own definition: "Tool name 'list_device_groups' and description 'List all device groups' clearly indicate data retrieval with no modification or side effects."

## Use case

AI agents call list_device_groups to retrieve information from Fortimanager 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 Fortimanager:

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