Strava MCP gateway

Connect ChatGPT to Strava with a stateless TypeScript relay and a browser-guided sign-in. Deploy to Cloudflare or Vercel without application secrets or a database.

Deploy

Click a deploy button and use the assigned public HTTPS URL. The relay detects its URL automatically.

For ChatGPT Sites, use the deployment prompt. The /api/mcp route configuration still needs a published check; Sites intercepts /mcp.

Connect Strava

1. Add the MCP URL shown on your deployment's homepage to ChatGPT using OAuth with CIMD, token authentication none, and scope mcp:read. It defaults to https://YOUR-DEPLOYMENT/mcp.

2. Follow the gateway's sign-in page to Strava. After signing in, copy the full http://localhost:61847/callback?... address from the browser's address bar, even though the page cannot load.

3. Paste that address into the original gateway page to finish linking.

No local installation is required. This copy-and-paste step is required for each new authorization; ChatGPT refreshes tokens through the gateway afterward. Strava always receives the localhost redirect URI during authorization and code exchange.

See OAuth settings, configuration, and limitations. Live ChatGPT-to-Strava linking remains unverified.
