Klutch × MCP A Model Context Protocol server for your credit card.

Tell your AI. Your card listens.

Write spending controls in plain English, then ask your assistant anything about where the money actually went. Connect the Klutch MCP server to Claude or ChatGPT and your credit card starts taking instructions — and answering questions — without a dashboard, toggle, or menu in sight.

Lock my Travel card when I get home Friday, and cap my Groceries card at $200 per day starting today.

Done. Two rules live on your account: the Travel card will auto-lock Friday evening, and your Groceries card now holds a $200/day ceiling, resetting at midnight. Want me to schedule a Sunday report on how close you got?

  3. 03

    Start asking.

    Type the rule you want — the model picks the tools, fills the arguments, and shows you what it built.

    "Cap my takeout at $50 a week and block DoorDash after midnight."

for the traveler

Plan the Lisbon trip — then make the card behave.

Give my Travel card a $2,400 ceiling between May 3 and May 17, and block anything outside Portugal during that window. Auto-lock it on the 18th.

Built three rules on Travel ••2847: StartEnd · $2,400 · May 3–17 Decline · country ≠ PT LockCard · activates May 18 00:00 You're covered. Want the trip summary pre-filled from last year's Portugal spend?

for the parent

Give the kid a card — with guardrails.

My son is 15. Give him the secondary card with $40/week, nothing after 9pm, nothing online, and auto-decline anything over $25 in a single transaction.

Four rules on Secondary ••0412: Accumulating · $40 · WEEK TimeOfDay · 06:00–21:00 Decline · CARD_PRESENT = false Decline · AMOUNT > 25 He'll see declines in-app. I can text you a daily recap if you want.

for the operator

Close the month without touching a dashboard.

Sum my business card spend this quarter, group it by merchant, and hard-cap the card at $8k for Q2. Exempt the AWS charges from the cap.

Q1 total: $23,418.72 across 142 charges. Top merchants: AWS, Figma, Notion, Linear, Vercel. Built on Business ••5509: Accumulating · $8,000 · QUARTER filter · LEGAL_NAME ≠ "Amazon Web Services" The rule ignores AWS toward the cap. Q2 starts clean.

§ 08Your card. Your rules. Your words.

The menu is gone.
Just say it.
