Given a patient id, construct a 360 view of a patient, their information, medical data and most recent vital signs
AI agents call wxoGetPatient360 to retrieve information from Hospital Data 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 comprehensive patient data including medical history, vital signs, and personal information based on a patient ID. While it accesses highly sensitive healthcare data (raising severity to 'high' due to HIPAA/privacy implications and potential for unauthorized access to personal medical information), the operation itself is read-only with no side effects.
From the tool's definition Tool name 'wxoGetPatient360' and description 'construct a 360 view of a patient, their information, medical data and most recent vital signs' indicate data retrieval without modification.
