WHOOP MCP Server

WHOOP MCP Server

A Model Context Protocol (MCP) server that provides access to all WHOOP API endpoints. This server allows you to integrate WHOOP fitness and health data into your applications through the MCP standard.

Features

• Complete WHOOP API Coverage: Access to all WHOOP v2 API endpoints
• OAuth 2.0 Authentication: Secure authentication flow
• User Data: Profile information and body measurements
• Cycles: Physiological cycle data with strain and heart rate metrics
• Recovery: Recovery scores, HRV, and resting heart rate data
• Sleep: Detailed sleep analysis including stages and performance metrics
• Workouts: Exercise data with strain, heart rate zones, and activity metrics
• Pagination Support: Handle large datasets with pagination
• TypeScript: Full type safety and IntelliSense support

Prerequisites

• Node.js 18+
• WHOOP Developer Account
• WHOOP API credentials

Setup

1. Install Dependencies

npm install

2. WHOOP API Setup

1. Go to the WHOOP Developer Platform
2. Create a new application
3. Note your Client ID and Client Secret
4. Set your redirect URI (e.g., http://localhost:3000/callback)

3. Environment Configuration

Copy the example environment file and configure your WHOOP credentials:

cp env.example .env

Edit .env with your WHOOP API credentials:

# WHOOP API Configuration
WHOOP_CLIENT_ID=your_client_id_here
WHOOP_CLIENT_SECRET=your_client_secret_here
WHOOP_REDIRECT_URI=http://localhost:3000/callback

# MCP Server Configuration
MCP_SERVER_PORT=3001

4. Build and Run

# Build the project
npm run build

# Run the MCP server
npm start

# Or run in development mode
npm run dev

Authentication Flow

The MCP server supports OAuth 2.0 authentication with WHOOP. Here's how to authenticate:

1. Get Authorization URL: Use the whoop-get-authorization-url tool to get the OAuth URL
2. User Authorization: Direct users to the authorization URL
3. Copy Authorization Code: When WHOOP redirects you back, copy the authorization code from the URL
4. Share Code with Claude: IMPORTANT - You must copy and paste the authorization code directly to Claude in the chat
5. Exchange Code: Claude will use the whoop-exchange-code-for-token tool with the authorization code
6. Set Access Token: Claude will use the whoop-set-access-token tool to set the access token for API calls

⚠️ Important Note About Authorization Codes

When you complete the WHOOP authorization in your browser, you'll be redirected to a URL that contains an authorization code. You must copy this code and paste it directly into your chat with Claude. The code will look something like this in the URL:

http://localhost:3000/callback?code=ABC123XYZ789&scope=read:recovery%20read:cycles...

Copy the code parameter value (e.g., ABC123XYZ789) and paste it in your chat with Claude. Claude will then use this code to exchange it for an access token and set up the connection to your WHOOP data.

Usage Examples

Getting User Profile

// First set your access token
await callTool('whoop-set-access-token', { accessToken: 'your_access_token' });

// Then get user profile
const profile = await callTool('whoop-get-user-profile', {});

Getting Recent Cycles

const cycles = await callTool('whoop-get-cycle-collection', {
  limit: 10,
  start: '2024-01-01T00:00:00Z'
});

Getting Sleep Data

const sleepData = await callTool('whoop-get-sleep-collection', {
  limit: 5,
  end: '2024-01-31T23:59:59Z'
});

Getting Workout Data

const workouts = await callTool('whoop-get-workout-collection', {
  limit: 10,
  start: '2024-01-01T00:00:00Z'
});

Data Types

The server provides comprehensive TypeScript types for all WHOOP API responses:

• User Data: Profile information, body measurements
• Cycles: Strain scores, heart rate data, kilojoule expenditure
• Recovery: Recovery scores, HRV, resting heart rate, SpO2, skin temperature
• Sleep: Sleep stages, performance metrics, respiratory rate, efficiency
• Workouts: Activity strain, heart rate zones, distance, altitude data

Pagination

Most collection endpoints support pagination with the following parameters:

• limit: Number of records to return (max 25)
• start: Start time filter (ISO 8601)
• end: End time filter (ISO 8601)
• nextToken: Token for next page

Error Handling

The MCP server includes comprehensive error handling:

• Invalid credentials
• Rate limiting
• Network errors
• Invalid parameters
• Missing required fields
