Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

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 2026-04-17.

Scoring dimensions (0–5):

  • Security & resilience (35%): documented OAuth, token refresh, retry/backoff, and explicit secure token file permissions (0600)
  • 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, and lean runtime dependency count (<=2)

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:

Watch the video

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:

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?"

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

| Variable | Required | Description | |----------|----------|-------------| | WHOOP_CLIENT_ID | Yes | Your WHOOP Developer App client ID | | WHOOP_CLIENT_SECRET | Yes | Your WHOOP Developer App client secret |

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

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.
