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

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

## Why update_address_group is rated Medium

The tool updates firewall address group objects, which is a reversible modification of network security configurations. This is a Write operation rather than Execute because it modifies policy data directly rather than triggering code execution. Severity is high because misconfigured address groups can affect network security posture and traffic filtering rules across managed devices.

From the tool's own definition: "Tool name 'update_address_group' and server context (FortiManager for firewall policy management and network configuration) indicate modification of address group configurations."

## Use case

AI agents use update_address_group to create or update resources in FortiManager MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your FortiManager MCP Server environment.
