Why smartlead_unsubscribe_lead_from_all_campaigns needs a policy

Unsubscribing a lead from ALL campaigns across the entire account is a broad, difficult-to-reverse action. It removes the lead's active participation in every campaign simultaneously, which likely cannot be easily undone and has significant blast radius — a single call affects all campaigns, not just one. This goes beyond a simple write/update and constitutes an irreversible or hard-to-reverse bulk operation.

How to control smartlead_unsubscribe_lead_from_all_campaigns

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_unsubscribe_lead_from_all_campaigns:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "smartlead_unsubscribe_lead_from_all_campaigns"
  ]
}

smartlead_unsubscribe_lead_from_all_campaigns disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.
