Whoop MCP Server

whoop-ai-mcp

An MCP (Model Context Protocol) server that connects AI assistants like Claude to your WHOOP health and fitness data. Ask questions about your recovery, sleep, workouts, and more — all through natural conversation.

📦 Published on the MCP Registry as io.github.shashankswe2020-ux/whoop — discoverable by any MCP-compatible client.

Features

• 🏋️ 12 health data tools — recovery, sleep, workouts, cycles, body measurements, profile, weekly summaries, trend analysis, period comparisons, and individual record lookups
• 📊 4 MCP Resources — ambient health context (latest recovery, sleep, cycle, profile) available without explicit tool calls
• 💬 5 MCP Prompts — guided conversation starters for common health queries
• 📅 Natural date expressions — use "last 7 days", "this week", "yesterday" instead of ISO 8601
• 📈 Built-in analytics — weekly summaries, trend detection (linear regression), and period comparisons computed server-side
• 🔐 Secure OAuth2 — browser-based authentication with automatic token refresh
• 🔄 Resilient — automatic retry on rate limits, token refresh on expiry, auto-pagination, clear error messages
• 💾 Secure token storage — tokens stored at ~/.whoop-mcp/tokens.json with 0600 permissions
• ⚡ Zero config — just add your WHOOP app credentials and go
• 📦 Lightweight — only two runtime dependencies (@modelcontextprotocol/sdk + zod)

Deep comparison ratings (WHOOP MCP packages on npm)

Evidence basis: npm registry metadata + npm-hosted README signals + package manifest fields (dependencies, repository, mcpName) collected on 2026-05-30.

Scoring dimensions (0–5):

• Security & resilience (35%): documented OAuth, token refresh, retry/backoff, secure token file permissions (0600), no shared relay
• Freshness (25%): recency of latest npm publish
• Docs & verification signals (25%): README coverage for OAuth, testing, changelog/release notes, and MCP Inspector usage
• Discoverability & portability (15%): MCP Registry metadata (mcpName), repository metadata present, lean runtime dependency count, no external infra required

Ratings are documentation/metadata-driven and are not a source-code security audit.

🎥 Video Walkthrough

Watch a detailed walkthrough of setting up and using whoop-ai-mcp with Claude Desktop:

Covers: creating a WHOOP Developer App, configuring Claude Desktop, OAuth authentication, and querying your health data through natural conversation.

Prerequisites

1. A WHOOP account with an active membership
2. A WHOOP Developer App — create one at developer.whoop.com
   • Set the redirect URI to http://localhost:3000/callback
3. Node.js >= 20

Get a WHOOP

Don't have a WHOOP yet? Here's how to get started:

• 🛒 Buy a WHOOP on Amazon — WHOOP peak on Amazon
• 🔗 Join WHOOP directly — whoop.com/membership

Quickstart (MCP Registry)

This server is published on the official MCP Registry. MCP clients that support the registry can discover and install it automatically:

Server name: io.github.shashankswe2020-ux/whoop

You can also browse it via the registry API:

curl "https://registry.modelcontextprotocol.io/v0.1/servers?search=io.github.shashankswe2020-ux/whoop"

Quickstart (Claude Desktop)

Add this to your Claude Desktop configuration file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "whoop": {
      "command": "npx",
      "args": ["whoop-ai-mcp"],
      "env": {
        "WHOOP_CLIENT_ID": "your_client_id",
        "WHOOP_CLIENT_SECRET": "your_client_secret"
      }
    }
  }
}

Replace your_client_id and your_client_secret with the credentials from your WHOOP Developer App.

On first launch, a browser window will open for you to authorize access to your WHOOP data. After authorizing, tokens are cached locally and refresh automatically.

Then ask Claude something like:

"How was my recovery this week?"

"Show me my sleep data from the last 3 days"

"What workouts did I do this month?"

"Is my HRV trending up or down?"

"Give me a weekly health summary"

Installation

Via npx (recommended)

No installation needed — Claude Desktop runs it automatically with the config above.

Global install

npm install -g whoop-ai-mcp

From source

git clone https://github.com/shashankswe2020-ux/whoop-mcp.git
cd whoop-mcp
npm install
npm run build

Configuration

Environment Variables

Set these in your Claude Desktop config (see Quickstart) or as shell environment variables:

export WHOOP_CLIENT_ID=your_client_id
export WHOOP_CLIENT_SECRET=your_client_secret

Creating a WHOOP Developer App

1. Go to developer.whoop.com
2. Create a new application
3. Set the Redirect URI to http://localhost:3000/callback
4. Set the Privacy Policy URL (required by WHOOP) — you can use https://github.com/shashankswe2020-ux/whoop-mcp or your own URL
5. Enable the following scopes:
   • read:profile
   • read:recovery
   • read:sleep
   • read:workout
   • read:cycles
   • read:body_measurement
6. Copy the Client ID and Client Secret

Tools

get_profile

Get the authenticated user's basic profile — name and email.

Parameters: None

---

get_body_measurement

Resources

MCP Resources provide ambient health context — AI assistants can read your current health state without explicit tool calls.

Privacy: Resources expose the same data available through tools — they simply make it accessible as ambient context. No additional WHOOP scopes are required. Data is cached in-memory with short TTLs and invalidated on token refresh.

To disable resources: set WHOOP_MCP_DISABLE_RESOURCES=1.

---

Prompts

Pre-built conversation starters that guide you into useful health queries:

Authentication

whoop-ai-mcp uses OAuth2 Authorization Code flow with PKCE:

1. First run: A browser window opens for you to authorize with WHOOP
2. Token caching: Access and refresh tokens are saved to ~/.whoop-mcp/tokens.json
3. Auto-refresh: When the access token expires, it's automatically refreshed using the stored refresh token
4. Re-authentication: If the refresh token expires, you'll be prompted to authorize again

Token files are stored with 0600 permissions (user-only read/write).

Troubleshooting

"Missing required environment variable: WHOOP_CLIENT_ID"

Your WHOOP credentials aren't set. Add them to your Claude Desktop config or set them as environment variables. See Configuration.

"Network error: Unable to reach the WHOOP API"

Check your internet connection. The WHOOP API must be reachable at https://api.prod.whoop.com.

"WHOOP API returned 429"

You've hit the rate limit. The server retries automatically with exponential backoff (up to 3 attempts). If this persists, reduce the frequency of your requests.

"WHOOP API returned 401"

Your access token has expired. The server attempts an automatic refresh. If that fails, delete ~/.whoop-mcp/tokens.json and restart to re-authenticate:

rm ~/.whoop-mcp/tokens.json

Browser doesn't open during authentication

If the browser doesn't open automatically, check the terminal output for the authorization URL and open it manually.

Testing with MCP Inspector

You can interactively test the server using the MCP Inspector — a browser-based tool for exploring and invoking MCP tools.

WHOOP_CLIENT_ID=your_client_id \
WHOOP_CLIENT_SECRET=your_client_secret \
WHOOP_REDIRECT_URI=http://localhost:3000/callback \
npx @modelcontextprotocol/inspector node dist/index.js

Then open http://localhost:6274 in your browser. The Inspector connects to the server, lists all available tools, and lets you invoke them with custom parameters.
