Get heart rate data (5-minute intervals)
AI agents call get_heart_rate to retrieve information from Oura 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 historical heart rate measurements from an Oura Ring without creating, modifying, deleting, or executing any actions. It is purely informational and read-only, presenting minimal risk even if accessed by an AI agent.
From the tool's definition Tool name is "get_heart_rate" and description states "Get heart rate data (5-minute intervals)" — explicitly a retrieval operation with no modification or execution.
