How to control smartlead_update_email_account_warmup

PolicyLayer is an MCP gateway — it sits between your AI agents and SmartLead MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for smartlead_update_email_account_warmup:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "smartlead_update_email_account_warmup": {
      "limits": [
        {
          "counter": "smartlead_update_email_account_warmup_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}
