Your bot can shop anywhere. It can't spend without you.

BuyLeash sits between an AI purchasing agent and your money. The agent asks, you approve, and it receives one single-use card for that merchant and that amount. Every request, approval, card, and receipt lands in a ledger you own.

Policy the bot can't edit

Caps per purchase, day, and month. Merchant allow and deny lists. A halt switch.

One card per approval

Scoped to the total, closed when the order is placed or the window passes.

A persona, not your passwords

Alias email and phone, shipping identity, guest checkout by default.

Works with any MCP agent

Grok Bot, Claude, or anything that speaks MCP over HTTP.
