Check your connection
Enter the same URL you'd give the AI — usually https://your-store.com/mcp. Nothing is sent anywhere except your own store; the checks run entirely in this browser tab.
What this can and can't tell you. These checks run from your machine and your location, so they reliably catch redirects, unreachable endpoints and base-URL mismatches — the most common setup problems. They can't fully reproduce what a remote AI's servers see: HTTP Basic-auth prompts and geo/IP-based redirects depend on your own browser and region. To verify the full sign-in flow end to end, follow the MCP Inspector guide.
