RewardVane

For your AI assistant

Ask your AI about cards. It answers from the library, with dates.

Point Claude, Cursor, Codex or any MCP client at one address. It can look a card up, work out which of your cards pays most on a purchase, check when points expire and find a SIM that keeps your number, all from the library this site reads, not from memory.

Server address

https://rewardvane.com/api/public/mcp

Streamable HTTP. No account, no key. Read-only.

Connect it in a minute

Pick your client and paste. There is no key to make or to keep safe.

Your client

Run this in a terminal:

claude mcp add --transport http rewardvane-library https://rewardvane.com/api/public/mcp

Any client that can add a remote MCP server by its address will work.

What it can answer

Six read-only tools. Each returns plain data your assistant can quote, with the page it came from.

  • find_cards

    Find a card

    Search by name, bank or nickname, then narrow by market, kind, reward type or no foreign fee. You get each card’s id, fees and the page that shows its rules.

    Ask: Which Hong Kong credit cards charge no foreign transaction fee?

  • get_card

    Read one card in full

    Annual fee and how it is waived, the foreign fee, every earning line with its cap and whether it needs registration, perks and offers, with the source page and the day it was checked.

    Ask: What does this card earn on dining, and what is capped?

  • best_card_for_purchase

    Which card pays most here

    Give it up to 40 cards and one purchase. It returns each card’s reward minus any foreign fee, worked out by the library’s rules, with the line that decided and what would pay more.

    Ask: I will spend 240 USD on dinner in Tokyo. Of these three cards, which pays most after fees?

  • list_points_programmes

    When do points expire

    Airline, hotel, card and club programmes: how long points last, what restarts the clock and what to watch, with the source page and the day it was checked.

    Ask: Which of these programmes take my points away if I do nothing for a year?

  • list_sims

    Find a travel SIM

    Whether your number is kept and how to keep it alive, where texts and data work, each plan’s price and the cheapest year, with the source page and the day it was checked.

    Ask: Which eSIM keeps my Hong Kong number working while I am in Japan?

  • search_guides

    Find a guide

    Plain-language guides on how a rule works and what to do before a fee posts: titles, summaries and links.

    Ask: How do I avoid foreign transaction fees?

searchfetch

For research assistants: search, then open

Assistants that research with a plain search-then-open pair, ChatGPT’s deep research among them, can look any card, programme, SIM or guide up by a word or two with search, then read it whole with fetch. Both return the same library data, each with the page to cite.

Why you can repeat what it says

  • Every figure has a date

    Details of a card, a programme or a SIM come with the page they were read from and the day somebody last read it. Your assistant is told to say that day: terms change, and the issuer’s own page decides.

  • Worked out, not guessed

    Which card pays most is calculated by the same rules as the site’s own comparison, from each card’s published earning lines and after any foreign fee. Points and miles are counted, never turned into cash.

  • Nothing about you

    No account, no key, no cards you hold. To count requests the server stores only a hash of your address, mixed with a secret and the date, so it cannot be turned back into the address or followed from one day to the next. What you asked is never stored.

Two servers, two jobs

This one knows the library and nothing about you. To let an assistant see your own cards, benefits and dates, use the connector in your account.

Library server (this page)

  • Open to any assistant, with no sign-in.
  • Answers about cards in general: fees, earning lines, programmes, SIMs and guides.
  • Read-only: there is nothing in it to change.

Personal connector (your account)

  • A key you make in your account, shown once and revocable at any time.
  • Reads only the part of your cards, benefits and dates that you chose to share from your phone.
  • Needs the global edition of the app.

Fair use

  • Up to 60 requests a minute for each client, and a request can be up to 8 KB.
  • This is reference information, not financial advice. There is nothing to apply for, buy or change from here.
  • It covers the five markets the library covers: the US, Hong Kong, Japan, Taiwan and mainland China.
