Why smartlead_remove_email_from_campaign needs a policy

Removing an email account from a campaign is an irreversible dissociation action — once removed, the account's campaign association and any related sending history/configuration tied to that pairing is lost. This is not a simple update but a permanent removal, making it Destructive. The blast radius is high because misuse could disrupt active email marketing campaigns by removing sending accounts.

How to control smartlead_remove_email_from_campaign

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

policy.json

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

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