Why smartlead_update_campaign_sequence needs a policy

This tool creates or modifies data reversibly by updating email content in a campaign sequence. While not destructive (changes can be undone), it directly alters campaign communications that will be sent to potential customers. The high severity reflects that an agent could modify emails to inject malicious content, phishing links, or inappropriate messaging that damages business reputation and legal compliance.

From the tool's definition Tool description states: 'Update a specific email in a campaign sequence.' The action modifies email content/configuration within an active campaign sequence, which affects outgoing communications to leads.

How to control smartlead_update_campaign_sequence

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

policy.json

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

smartlead_update_campaign_sequence stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
