MaxWorth MCP · ChatGPT & Claude

Ask ChatGPT or Claude about your own cards.

Connect MaxWorth once and your assistant can read the cards, credits and offers you track in the app: what expires this month, which card has an offer at a store, whether a card earned back its fee.

Endpointmcp.maxworth.app/mcp Works in ChatGPT, Claude, Claude Code, Cursor and other MCP clients.

What you can ask

Signed in, your assistant can answer from the cards you track. A few questions people actually ask:

Your cards at a glanceEvery card you added, its annual fee, and how its credits and offers stand.
“Summarize my cards and what I pay in annual fees each year.”“How many credits do I have left to use across all my cards?”
Credits and their deadlinesEvery credit on your cards, this period’s status and end date, and whether it needs enrollment.
“Which credits on my Amex Platinum haven’t I used this quarter?”“Do any of my credits still need enrollment before I can use them?”
What’s about to expireUnused or partly used credits ending soon, soonest first, with what’s left.
“What credits expire in the next 7 days, and how much is left on each?”“What should I use before my Sapphire Reserve renews?”
Your Chase and Amex offersThe offers the extension synced: which card, added or not, and days left.
“I’m buying running shoes at Nike. Do any of my cards have an offer?”“Which of my activated offers expire this week?”
Is each card worth its fee?Fee, credits redeemed this year, what’s still open, and the next fee date.
“Is my Sapphire Reserve paying for its fee this year?”“Which of my cards should I think about canceling before the fee posts?”

Get the iPhone app

Read-only, and only what you added.

It can’t change anything.
Every tool only reads. It can’t add cards, mark credits or activate offers.
It sees what you track, nothing more.
Your cards, their credits and the offers the extension synced. MaxWorth never connects to a bank, so there are no transactions to read.
You can switch it off.
Disconnect the connector in your assistant and its access ends.
No account? Use the public server

Card facts for anyone, no sign-in.

A second server answers general questions from the MaxWorth card catalogue. It doesn’t know who you are, so it can’t see your cards. Connect it the same way, with authentication set to none.

Questions

What is MCP?

The Model Context Protocol is the open standard assistants such as ChatGPT and Claude use to call outside tools, so they answer from real data instead of guessing.

Can it see my bank account?

No. Neither server, and not the MaxWorth app itself, ever connects to a bank or sees a transaction.

Do the app and my assistant agree on deadlines?

Yes. Deadlines are computed the same way the app computes them, from each card’s dates and each credit’s cycle.

Where can I find it in a registry?

Both servers are in the official MCP Registry as app.maxworth/maxworth and app.maxworth/maxworth-public.
