Tools
read tools are read-only; write tools mutate data (clients should confirm them); meta tools report usage, manage your subscription or send a feature request.
Pricing
*Pro has a fair use limit of 10,000 tool calls a month on this server. For more, write to [email protected].
Pro covers this server only. Subscribe with stamped_upgrade (it returns a Stripe Checkout link). Cancel any time with stamped_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running stamped_upgrade before then undoes the cancel. Or write to [email protected].

Account eligibility and data
This initial release supports API-enabled Loyalty 2.0 shops. Legacy V2 reviews and review-only accounts are unavailable. No public key is needed. Customer contacts, addresses, orders and loyalty records requested through tools reach your chosen AI client and its LLM provider; API keys do not. Coupon codes are masked. No points adjustments, redemption, review publishing or other merchant writes are exposed.
Revoke the dedicated key in Stamped to stop access. Usage and billing identity follow the shop ID. Requests are never automatically retried. Independent integration; no Stamped approval or endorsement claimed.
