THE RISK

Low Risk

Why smartlead_search_domain needs a policy

This tool retrieves domain availability information based on search criteria but does not create, modify, delete, or execute any operations. It performs a simple informational query against domain databases. The blast radius is minimal—an AI agent misusing this tool would only retrieve unwanted domain information, posing no financial, destructive, or operational risk.

From the tool's definition The tool description explicitly states it 'Search[es] for available domains' which is a query operation with no side effects. The verb 'search' and the read-only nature of domain availability lookup indicate information retrieval only.

POLICY

How to control smartlead_search_domain

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_search_domain:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "smartlead_search_domain": {}
  }
}

smartlead_search_domain is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
