## Why add_subdomain is rated Medium

An AI agent can call add_subdomain faster than any human can review: one bad instruction and it creates or modifies resources in Timeweb by the hundred, each call as confident as the last.

## Use case

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

## Recommended policy (PolicyLayer)

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

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