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

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

## Why add_visitor is rated Medium

This tool creates new visitor/user accounts in the network access control system, which is a Write operation—data is created and can be modified or deleted. Severity is medium because compromised account creation could enable unauthorized network access, but the blast radius is somewhat contained by the visitor account nature and expiration settings.

From the tool's own definition: "Create a Central NAC visitor account. The tool generates new user accounts with parameters for username (name=login username) and expiration time (expire_at ISO 8601), which are reversible creations of authentication credentials."

## Use case

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

## Recommended policy (PolicyLayer)

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

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