WHAT IT DOES

What get_domain_whois does on 20i MCP Server

AI agents call get_domain_whois to retrieve information from 20i MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why get_domain_whois is rated Low

WHOIS queries retrieve publicly available domain registration information without altering any state. The verb 'Get' and passive data retrieval nature place this firmly in the Read category. Severity is low because WHOIS data is public information and the operation has no blast radius beyond information disclosure (which occurs naturally for domains).

From the tool's definition Tool name 'get_domain_whois' and description 'Get live WHOIS data for domain' indicate a read-only retrieval operation with no modification or side effects.
