Replaced 18 granular WHOOP tools with 7 streamlined tools and added an embedded HTTP callback server so users can complete the OAuth flow directly from Claude without needing to run a separate auth app. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
WHOOP's OAuth endpoint requires a `state` parameter with a minimum length. The authorize_whoop handler was calling getAuthorizationUrl() without one, causing an `invalid_state` error on redirect. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Track callback server instance to prevent port conflicts on repeat calls - Close existing server before starting new one - Add error handler for EADDRINUSE with retry - Listen on 0.0.0.0 instead of default (fixes localhost connection issues) - Extend timeout from 5 to 10 minutes - Handle OAuth error responses in callback - Add exchange_code tool as manual fallback when callback fails Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Tokens are now saved to whoop-tokens.json after auth and loaded automatically on server startup. If the access token is expired, it auto-refreshes using the saved refresh token. This means users only need to authorize once — subsequent restarts reuse the saved tokens. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Add 'offline' scope to OAuth request so WHOOP returns a refresh token - Fix loadTokens to properly reject expired tokens without refresh tokens instead of silently using them (which caused auth failures in new chats) - Mark isAuthorized=false on refresh failure so user gets a clear re-auth prompt Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
The MCP server previously only refreshed tokens at startup, so the access token expiring mid-session (~1 hour) required restarting Claude. This adds an axios response interceptor that catches 401 errors, auto-refreshes the token, saves new tokens to disk, and retries the original request transparently. Concurrent requests are queued so only one refresh happens at a time. Also adds WHOOP-MCP-SETUP-GUIDE.md with architecture, auth flow, troubleshooting, and lessons learned.
