Find promo codes with ChatGPT
ChatGPT can use remote MCP servers as custom apps (connectors). Once CouponLlama is added, ChatGPT can check for a promo code before you buy.

In ChatGPT, open Settings, then Apps & Connectors, and turn on Developer mode under Advanced settings. Business and Enterprise workspaces need an admin to allow custom apps.
Choose Create, name it CouponLlama, and paste the server URL. Set authentication to No authentication.
MCP server URL https://couponllama.com/mcpConfirm, then pick CouponLlama from the + menu in a new chat.
Check it works. Ask: “Check CouponLlama for a code before I order from this store.”
Menus move between versions of ChatGPT. If a step doesn’t match what you see, look for “MCP”, “connectors” or “integrations” in its settings; the server URL above is all it needs.
