MaxWorth MCP server
Give ChatGPT, Claude or any MCP client the same hand-verified credit card data that powers the MaxWorth app: every card in the US, Canada and Australia, every statement credit with its reset date, live cashback portal rates, and the Credit Deadline Report. Public data only; nothing about any user.

Try asking
- “When does the Amex Platinum hotel credit reset, and do I need to enroll?”
- “Compare the Chase Sapphire Reserve and the Capital One Venture X on credits and annual fee.”
- “Which cashback portal pays the most at Nike today?”
- “How many credit deadlines does the average premium cardholder face in a year?”
What it will not do
- It cannot see your cards or your wallet. There is no login; the MaxWorth app itself never connects to a bank account either.
- It does not give personalised financial advice. It returns the issuer's published terms as catalogued and verified by MaxWorth, with a URL to cite.
- Portal rates are checked daily, not live to the minute; each rate carries its check date.
MaxWorth is a privacy-first credit card benefits tracker: recurring credits, annual-fee ROI, card-linked offers and cashback portal rates — without connecting a bank account. maxworth.app · llms.txt · App Store
