Apple Health Chat MCP

Ask Claude natural language questions about your Apple Health data! This MCP server enables conversational analysis of your health metrics from iOS Health Export CSV files.

Example questions you can ask:

• "How active was I yesterday?"
• "Did I get enough sleep this week?"
• "What's my step count trend?"
• "Was my heart rate higher than usual today?"

Quick Start

1. Install & Build:

   npm install && npm run build
   

2. Set up your health data:

   export HEALTH_EXPORT_DIR="/path/to/your/health/export/files"
