Connects Muse to a catalog of credit cards, loyalty programs and airline award charts. Muse can compare cards side by side, find cards by annual fee or benefit, check 0% APR and balance transfer offers, look up points valuations and transfer partners, and see which airlines a mileage program can book.

Example request: "Which cards earn the most on groceries with no annual fee, and how much are Chase points worth right now?"

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use CardCurator to help me. It is a free service with an MCP server at https://cardcurator.ai/mcp. It does not need an API key. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.

Tools:
- search_cards: Search and filter the credit card catalog by bank, program, annual fee, card type, or credit range. Use this first when the user names a card or asks which card to choose; pass an ID returned here to get_card_details. Only search CardCurator credit-card and rewards questions.
- get_card_details: Get full details for one CardCurator credit card, including credits, milestones, perks, APR offers, and portal values. Use only with a cardId returned by search_cards. Do not pass a card name, a natural-language question, or an ID invented by the model; call search_cards first.
- list_programs: List all loyalty programs (credit card, airline, hotel) with type, currency, and points valuations.
- get_transfer_partners: Get all transfer partners for a loyalty program, including transfer ratios and any active bonuses.
- get_active_transfer_bonuses: Get all currently active transfer bonuses across all programs. Optionally filter by source program.
- get_award_chart: Get award chart pricing for an airline loyalty program. Filter by cabin class or region.
- get_points_valuations: Get cents-per-point valuations (baseline, floor, ceiling) for loyalty programs.
- search_cards_by_benefit: Find credit cards by specific benefits, credits, or features. Use when asked "which cards have X credit/benefit?" Searches credit names, feature strings, and benefit categories. Returns cards ranked by total annual credit value.
- compare_cards: Compare 2–4 credit cards side-by-side. Returns fees, earn rates, signup bonuses, credits, transfer partner counts, and portal values for each card, plus a highlight summary.
- recommend_category_cards: Find the best credit cards for a specific spending category (e.g., groceries, dining, travel, gas, streaming). Returns cards ranked by earn rate for that category with effective annual fees.
- find_apr_cards: Find credit cards with 0% APR promotional offers. Use when users ask about 0% APR cards, financing purchases interest-free, or balance transfer options. Sorted by longest duration first.
- find_balance_transfer_cards: Find credit cards with 0% APR balance transfer offers. Optionally pass debtAmount and currentApr to calculate exact interest savings and net benefit for each card.
- get_bookable_partners: Get which airlines can be booked (award flights) using a specific airline loyalty program's miles. Use when asked "which airlines can I book with United miles?" or "can I use Aeroplan for Lufthansa?". Distinct from transfer partners — this is about redemption.
- recommend_program_cards: Recommend the best credit cards for a specific rewards program or issuer (e.g., "Chase", "Amex", "Delta", "Marriott", "Hyatt"). Returns cards ranked by overall value with top pick highlighted.
