Find promo codes with Gemini CLI
Gemini CLI connects to remote MCP servers over HTTP. Add CouponLlama once and every session can use it.
https://couponllama.com/mcpConnect Gemini CLI to CouponLlama
Run this in a terminal:
Terminal gemini mcp add --transport http couponllama https://couponllama.com/mcpOr add it to ~/.gemini/settings.json:
~/.gemini/settings.json { "mcpServers": { "couponllama": { "httpUrl": "https://couponllama.com/mcp" } } }Start Gemini CLI and run /mcp to see CouponLlama's tools.
Check it works. Ask: “Find me a promo code for a travel site.”
Menus move between versions of Gemini CLI. 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.

Gemini CLI and CouponLlama
Does Gemini CLI support MCP servers?
Yes. Gemini CLI can connect to remote MCP servers such as CouponLlama's, which runs at https://couponllama.com/mcp. The steps on this page add it.
Do I need a CouponLlama account or API key?
No. The CouponLlama MCP server is free and public. Leave any authentication setting empty or set it to none.
What can Gemini CLI do once CouponLlama is connected?
It can find promo codes for a store, search stores, list categories, latest promo codes and report whether a code worked. Ask in plain words, for example “Is there a promo code for this store?”.
