List all custom hostnames attached to a site with DCV/SSL status
AI agents call sitebay_list_custom_hostnames to retrieve information from SiteBay 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 information about custom hostnames and their SSL/DCV status. It performs a query operation with no capability to modify, delete, or execute actions. The blast radius of misuse is minimal—an agent could enumerate hostnames but cannot alter infrastructure or access sensitive data beyond what's already visible in hostname listings.
From the tool's definition Tool name 'list_custom_hostnames' and description 'List all custom hostnames attached to a site with DCV/SSL status' indicate data retrieval with no modification or side effects.
