An AI agent with access to this tool could maliciously or accidentally delete critical marketing folders, disrupting campaigns and losing operational data.

From the tool's definition Tool name contains 'delete' and description states 'Delete a smart delivery folder by ID' — this is an irreversible deletion operation.

POLICY

How to control smartlead_delete_folder

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_delete_folder:

policy.json

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

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

Create a free account and register SmartLead MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
