🎥 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.jsonWindows: %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 am I doing today?"

"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"

"Show me my recovery calendar for last 2 weeks"

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

Setup wizard (whoop-ai-mcp setup)

For a guided installation that writes the Claude Desktop config (or prints theclaude mcp add command for Claude Code) and verifies your WHOOP credentialsin one go:

npx whoop-ai-mcp setup

Flags:

• --client=claude-desktop (default) writes/merges claude_desktop_config.jsonwith an automatic .bak backup.
• --client=claude-code prints the equivalent claude mcp add command.
• --verify runs the OAuth flow end-to-end and fetches your profile to confirmeverything is wired correctly before exiting.
• --client-id / --client-secret skip the interactive prompts (useful forscripts; secrets entered interactively are masked).

If WHOOP_CLIENT_ID and WHOOP_CLIENT_SECRET are already exported in yourshell, the wizard uses them automatically — no prompts. Combine with--verify to do a one-shot config-correctness check:

WHOOP_CLIENT_ID=... WHOOP_CLIENT_SECRET=... npx whoop-ai-mcp setup --verify

If the Claude Desktop config file already contains a whoop MCP entry froma previous setup, the wizard short-circuits — it reads the existingcredentials, prints Existing whoop entry found in <path>, and eitherverifies them (with --verify) or exits without rewriting the file. Tooverwrite an existing entry, pass explicit --client-id / --client-secretflags.

Precedence: --client-id / --client-secret flags > existing claude-desktopconfig > WHOOP_CLIENT_ID / WHOOP_CLIENT_SECRET env vars > interactiveprompts.

Example session:

shashankmishra@Shashanks-MacBook-Pro ~ % npx whoop-ai-mcp setup --client=claude-desktop

Restart Claude Desktop to load the new server.

Re-running against an already-configured Claude Desktop install (existingwhoop entry in claude_desktop_config.json) short-circuits to averification-only flow — no prompts, no rewrite:

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.

Deployment (Docker + Cloud Hosting)

The HTTP transport (MCP_TRANSPORT=http) makes this server suitable for remotehosting so that web/mobile MCP clients (e.g. claude.ai connectors) can connectto your personal WHOOP data over the network. A production-readyDockerfile is included.

Security warning. When running over HTTP you are exposing your WHOOP databehind a single bearer token. Use a strong random MCP_AUTH_TOKEN(openssl rand -hex 32), only deploy behind TLS, restrictMCP_ALLOWED_ORIGINS, and treat the host as a personal-use deployment — nota multi-tenant service.

Image characteristics

• Multi-stage build on node:22-alpine (compressed pull size ~58 MB;uncompressed ~258 MB — the floor is set by the Node.js runtime itself).
• Runs as the unprivileged built-in node user (UID 1000).
• tini as PID 1 for clean signal forwarding (graceful shutdown).
• Health check uses Node's native fetch against /health — no curl/wgetbaked into the image.
• All configuration is supplied at runtime via env vars; no secrets are bakedinto image layers.

Build & run locally

docker build -t whoop-mcp .

# Smoke test (runs node, prints "ok", exits)
docker run --rm whoop-mcp node -e "console.log('ok')"

# Run the HTTP server
docker run --rm -p 3000:3000 \
  -e MCP_AUTH_TOKEN="$(openssl rand -hex 32)" \
  -e WHOOP_CLIENT_ID="your-client-id" \
  -e WHOOP_CLIENT_SECRET="your-client-secret" \
  -e MCP_ALLOWED_ORIGINS="https://claude.ai" \
  whoop-mcp

# Health check
curl http://localhost:3000/health

Required env vars (HTTP mode):

Fly.io

Fly.io deploys directly from the Dockerfile and gives you afree TLS-terminated public URL.

# One-time: install flyctl, sign in, and create the app from this repo's Dockerfile
brew install flyctl
fly auth login
fly launch --no-deploy --copy-config --name whoop-mcp-<your-suffix>

# Set secrets (these are encrypted and injected as env at runtime — never baked in)
fly secrets set \
  MCP_AUTH_TOKEN="$(openssl rand -hex 32)" \
  WHOOP_CLIENT_ID="..." \
  WHOOP_CLIENT_SECRET="..." \
  MCP_TRUST_PROXY=1

# Deploy
fly deploy
fly status
fly logs

In your generated fly.toml, make sure the HTTP service points at port 3000and that force_https = true is set under [[http_service]]. Fly handlesTLS termination, so MCP_TRUST_PROXY=1 is required for accurate client IPsin logs and rate-limit decisions.

Railway

Railway auto-detects the Dockerfile.

1. Create a new project from this GitHub repo (or railway up from a clone).
2. In Variables, add MCP_AUTH_TOKEN, WHOOP_CLIENT_ID,WHOOP_CLIENT_SECRET, and MCP_TRUST_PROXY=1.
3. Under Settings → Networking, generate a public domain. Railwayterminates TLS for you.
4. Deploy. Health check path: /health.

Other platforms

The image is a stock OCI artifact and runs anywhere Docker does — Render, CloudRun, Kubernetes, Hetzner, etc. The only platform-specific knob isMCP_TRUST_PROXY=1 whenever you sit behind a TLS-terminating proxy.

Connecting from claude.ai (OAuth 2.1 connector)

Claude Desktop and Claude Code can use the static MCP_AUTH_TOKEN bearerdirectly. The claude.ai web/mobile clients expect an OAuth 2.1 connectorwith PKCE — set the three env vars below and the server mounts the connectorautomatically on the same port as /mcp:

fly secrets set \
  MCP_CONNECTOR_PASSWORD="$(openssl rand -base64 24)" \
  PUBLIC_URL="https://whoop-mcp-<your-suffix>.fly.dev" \
  ALLOWED_REDIRECT_URIS="https://claude.ai/api/mcp/auth_callback"

• MCP_CONNECTOR_PASSWORD (≥12 chars) — the human-facing password you'll typeinto the claude.ai connector dialog. Treat it like any other shared secret.
• PUBLIC_URL — the public https:// origin claude.ai will reach. Used asthe OAuth issuer (e.g. https://example.com → metadata at/.well-known/oauth-authorization-server).
• ALLOWED_REDIRECT_URIS — comma-separated exact-match allowlist. Forclaude.ai the value is https://claude.ai/api/mcp/auth_callback.
• Optional: MCP_JWT_SECRET overrides the JWT signing key (defaults to anHKDF derivation from MCP_AUTH_TOKEN); MCP_OAUTH_CLIENT_ID overrides theadvertised client id (default whoop-mcp-connector).

In claude.ai → Settings → Connectors → Add custom connector, point it atPUBLIC_URL/mcp and supply MCP_CONNECTOR_PASSWORD when prompted.

See CHANGELOG.md for a full list of changes in each release.

Privacy notes for analytical tools

The analytical tools — get_weekly_summary, get_trend, andcompare_periods — return pre-computed statistical summaries derived fromyour underlying recovery / sleep / cycle / workout records. No new healthdata is exposed beyond what the per-record collection tools already return(get_recovery_collection, get_sleep_collection, etc.), but theaggregated form is more concentrated and easier to scan over time. Inparticular, the anomalies array returned by get_trend flags days thatdeviate from your personal baseline — such days may correlate withillness, injury, travel, or lifestyle changes.

If you connect this MCP server to a remote AI assistant (rather than alocal one), be aware that those summaries will be sent to that assistantin the same way any other tool result is. All data continues to flow onlybetween the WHOOP API, this MCP server running on your machine, and theassistant you explicitly invoke — there is no third-party telemetry.
