get_xml_by_type
AI agents call get_xml_by_type to retrieve information from Apple Health 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 health data in XML format filtered by type. It has no side effects—it queries Apple Health records without creating, modifying, or deleting data. The empty description reduces confidence slightly, but the consistent pattern across sibling tools and the naming convention ('get_*') clearly indicate a read operation.
