AI agents call whitepages_addresses to retrieve information from Outscraper MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
WhitePages is a public directory service. This tool retrieves address information without creating, modifying, or deleting data.

"default": "deny",
"tools": {
"whitepages_addresses": {}
}
