RightCard MCP helps agents pick the best credit card for a purchase using verified, two-source reward data.
best_card: Given card IDs and a store or category, returns which card earns the most today, with honest rates and caveats (merchant-code traps, rotating activation, ties).
lookup_merchant: Look up how a store is categorized and whether category bonuses usually won't post there (e.g., Costco, Walmart).
search_cards: Find credit card IDs by card or issuer name, with verified cards first and unverified cards flagged.
card: Get one card's verified earning rates, base rate, annual fee, rotating windows, and choose-your-category configuration.
rotating_calendar: See live and upcoming rotating 5% category windows and permanent merchant benefits, optionally filtered by card.
Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@rightcard-mcp I have Amex Gold, Freedom Flex and Citi Double Cash. Which card earns most at Costco?"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
The card-selection oracle for agents: which of your credit cards should pay here? Answers come from RightCard's bank-published, two-source-verified reward data — the same data the RightCard iOS app uses.
No bank login. No account. Nothing stored. You pass card ids and a store name; you get an answer.
Honest by construction: merchant-code caveats (Costco is a warehouse club, so the grocery bonus won't post), rotating quarters with activation flags, ties named, points valued per program.
Cash value by default; valuation: "points" for conservative travel values.
