## Facts

- Tool: `create_vlan`
- Server: API-Central (`secure-ssid/centralmcp`) — https://policylayer.com/tools/secure-ssid-centralmcp.md
- Homepage: https://github.com/secure-ssid/centralmcp
- Risk category: Write (Medium risk)
- Registry record: grade F, identity unverified
- Server rate-limited: no
- Parameters: 0
- Recommended policy verdict: Rate-limited

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

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

## Why create_vlan is rated Medium

This tool creates a new VLAN (Virtual LAN), which is a network configuration change. VLANs can be deleted or modified later, making this a Write operation rather than Destructive. However, the severity is high because misconfigured VLANs can disrupt network segmentation, isolate critical devices, or compromise network security policies if created improperly by an agent.

From the tool's own definition: "Tool name is 'create_vlan' and description states 'Create an L2 VLAN and scope-map it', indicating creation of network configuration that is reversible."

## Use case

AI agents use create_vlan to create or update resources in API-Central, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your API-Central environment.

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "create_vlan": {
      "limits": [
        {
          "counter": "create_vlan_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}
```
