WHOOP FastAPI + MCP Server

Full-stack WHOOP integration with FastAPI OAuth server and Model Context Protocol (MCP) server for Claude Desktop.

🚀 Features

• FastAPI OAuth Server - Authenticate with WHOOP and access your health data
• MCP Server - Integrate WHOOP data directly into Claude Desktop conversations
• Complete Data Access - Recovery, sleep, workouts, cycles, and body measurements
• Historical Queries - Access data from specific dates or date ranges
• Secure - OAuth 2.0 authentication with encrypted token storage

📦 What's Included

1. FastAPI Application (whoop_simple.py)

Web server for WHOOP OAuth authentication and data exploration:

• OAuth 2.0 flow with WHOOP API
• Dashboard with health metrics
• REST API endpoints for all WHOOP data
• Token caching for seamless access

2. MCP Server (whoop_mcp_server.py)

Model Context Protocol server for Claude Desktop integration:

• 8 tools for accessing WHOOP data
• Support for historical data queries
• Recovery scores, sleep analysis, workout tracking
• Cycles and strain monitoring

Prerequisites

• Python 3.10+
• VS Code with Python extension (optional)
• HTTPS dev URL (ngrok/cloudflared) for OAuth redirect
• Claude Desktop (for MCP integration)
• WHOOP Developer App credentials from developer.whoop.com

Quick Start

1. Install Dependencies

# Create virtual environment
python -m venv .venv

# Activate it
# Windows:
.venv\Scripts\activate
# macOS/Linux:
source .venv/bin/activate

# Install packages
pip install -r requirements.txt

2. Configure Environment

# Copy template
cp .env.example .env

Edit .env and add your credentials:

WHOOP_CLIENT_ID=your_client_id_here
WHOOP_CLIENT_SECRET=your_client_secret_here
PUBLIC_BASE_URL=https://your-ngrok-url.ngrok-free.dev

3. Setup OAuth Tunnel

# Start ngrok
ngrok http 3000

Copy the HTTPS URL and:

1. Update PUBLIC_BASE_URL in .env
2. Set callback URL in WHOOP Developer Console to:

   https://your-ngrok-url.ngrok-free.dev/callback
   

4. Authenticate with WHOOP

# Start FastAPI server
python whoop_simple.py

# Open browser to http://localhost:3000
# Click "Click here to login with WHOOP"
# Complete OAuth authorization

Once authenticated, a .token_cache.json file is created with your OAuth token.

5. Try FastAPI Endpoints

• http://localhost:3000/dashboard - Health dashboard
• http://localhost:3000/me - Profile + body measurements
• http://localhost:3000/daily?day=YYYY-MM-DD - Daily cycles

6. Setup MCP Server (Optional)

For Claude Desktop integration:

1. Configure Claude Desktop:

   Edit %APPDATA%\Claude\claude_desktop_config.json (Windows) or ~/Library/Application Support/Claude/claude_desktop_config.json (Mac):

   {
     "mcpServers": {
       "whoop-fitness": {
         "command": "C:\\path\\to\\.venv\\Scripts\\python.exe",
         "args": ["C:\\path\\to\\whoop_mcp_server.py"]
       }
     }
   }
   

2. Restart Claude Desktop

3. Test in Claude:

   • "What's my recovery score today?"
   • "Show me my last 7 days of data"
   • "How did I sleep last night?"

See docs/SETUP_MCP.md for detailed MCP setup instructions.

🐛 Troubleshooting

FastAPI Issues

• 404 errors: Ensure using /developer/v2/ API base
• OAuth callback fails: Verify ngrok is running and URLs match
• No data returned: Check scopes in WHOOP Developer Console include:
  • read:profile
  • read:body_measurement
  • read:cycles
  • read:recovery
  • read:sleep
  • read:workout

MCP Server Issues

• Claude Desktop doesn't see server: Check config file path and restart Claude Desktop
• "No access token found": Authenticate via FastAPI server first (http://localhost:3000/login)
• Tools not appearing: Verify Python path in config points to virtual environment
