🔧 Available Tools

ultrahuman_metrics

Fetches health and fitness metrics from the Ultrahuman API for a specific date. The user email is configured via environment variable, so you only need to specify the date to retrieve comprehensive health data.

Parameters:

• date: Date in YYYY-MM-DD format to fetch metrics for (e.g., '2025-06-19')

Example Usage:

{
  "name": "ultrahuman_metrics",
  "arguments": {
    "date": "2025-06-19"
  }
}

📊 Available Health Data

The API provides comprehensive health metrics including:

• Heart Rate: Continuous heart rate monitoring with timestamps
• Skin Temperature: Body temperature variations throughout the day
• HRV (Heart Rate Variability): Heart rate variability measurements
• Steps: Step count data with activity tracking
• Sleep Data: Detailed sleep analysis including:
  • Sleep stages (Deep, Light, REM, Awake)
  • Sleep efficiency and quality metrics
  • Heart rate and HRV during sleep
  • Temperature variations during sleep
• Recovery Index: Overall recovery score
• Movement Index: Activity and movement metrics
• VO2 Max: Cardiovascular fitness indicator

🧪 Testing

You can test the server by running it directly:

node dist/main.js

The server will listen for MCP requests on stdio and provide the ultrahuman_metrics tool to fetch health data from the API.

🛠️ Development

• Run tests: bun test
• Format code: bun run format
• Lint code: bun run lint
• Build project: bun run build

📜 Version Management

This project uses standard-version for automated version management. Run bun run release to create a new version.
