Build an Oura Ring Health Telemetry MCP Server for Wearable AI Agents in 2026

Build an Oura Ring Health Telemetry MCP Server for Wearable AI Agents in 2026

The Oura Ring generates approximately 2,500 data points per user per day across sleep stages, heart rate variability, blood oxygen saturation, skin temperature, and activity metrics. With Oura targeting a September 2026 IPO at $16B+ valuation and revenue growing from $500M in 2024 to a projected $2B this year, the company's health data platform is becoming essential infrastructure for AI-powered wellness. This FastMCP server exposes Oura's telemetry API to AI agents, enabling them to query health data, detect anomalies, and generate personalized recommendations.

The server provides six tools: daily health summary, sleep analysis, HRV trends, SpO2 monitoring, temperature deviation tracking, and anomaly detection. AI agents using this server can process a user's complete daily health profile in under 2 seconds.
