Find promo codes with Claude
Add CouponLlama as a custom connector and Claude can look up promo codes on claude.ai, in Claude Desktop and in the Claude mobile apps.
https://couponllama.com/mcpConnect Claude to CouponLlama
In Claude, open Settings, then Connectors.
Choose Add custom connector. On a Team or Enterprise plan, an owner adds it once for everyone from the organization's connector settings.
Name it CouponLlama and paste the server URL. Leave the OAuth fields empty: CouponLlama needs no sign-in.
Server URL https://couponllama.com/mcpSave, then switch CouponLlama on from the tools menu in any chat.
Check it works. Ask Claude for a promo code for a store you shop at, for example “Is there a promo code for huegahouse.com?” It should call find_promo_codes and answer with codes and their vote tallies.
Menus move between versions of Claude. 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.
