“What were my best-selling cards last week?”
ChatGPT will pull live data from your Hoard account.

Troubleshooting

ChatGPT does not show Create or custom MCP connectors Make sure Developer mode is turned on under Settings → Apps → Advanced settings. Custom MCP connectors may also depend on your ChatGPT plan and workspace settings. The Hoard sign-in window never appears Remove the failed connector, create it again, and use ChatGPT Connector as the connector name if ChatGPT asks for one. ChatGPT says the connector failed Make sure you pasted https://mcp.tryhoard.com/mcp exactly, including the trailing /mcp. ChatGPT shows a draft app but the OAuth flow fails after redirect Delete the draft and recreate it from Settings → Apps → Create. Use OAuth if ChatGPT asks which authentication method to use, and wait for the tool scan to finish before clicking Create.
