AI agents call whitepages_phones 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.
This tool retrieves phone contact information from public records (WhitePages), which is a Read operation—it queries and returns data without side effects. Severity is medium because phone number scraping at scale raises privacy concerns and potential misuse for harassment or social engineering, but the tool itself does not move money, execute code, or permanently destroy data.
From the tool's definition Tool name 'whitepages_phones' indicates retrieval of phone number data from WhitePages. Server description states the tool provides 'data extraction services' and 'contact information retrieval'.
