What it can do
Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.
smartrr_list_subscriptionsList customer subscriptions (Smartrr 'purchase states') with status, next billing date, selling plan, line items, shipping address, discounts and the customer (id, email, name). Filter by status, next billing date or creation date. The ids you need for the other tools: `id` (subs
smartrr_get_subscriptionOne subscription by its Shopify subscription id (the `shopifyId` field from smartrr_list_subscriptions, passed exactly as shown): status, schedule, next billing date, line items, discounts, shipping address, customer and payment method (brand, last digits and expiry only). GET /v
smartrr_list_customer_subscriptionsList the subscriptions of one customer, by Smartrr customer id (`custRel.id` from smartrr_list_subscriptions, or `id` from smartrr_list_customers). GET /vendor/customer/{customerRelationshipId}/purchase-state/.
smartrr_get_subscription_eventsThe 250 most recent events on a subscription (pause, skip, cancel, activate, billing attempts and failures, line-item and address changes, discounts) with who did it. GET /vendor/purchase-state/{shopifySubscriptionId}/events.
smartrr_get_subscription_ordersOrders generated by one subscription, by its Shopify subscription id. GET /vendor/purchase-state/{shopifySubscriptionId}/orders.
smartrr_get_subscription_billsBilling attempts of one subscription (amount, status pending/processing/succeeded/failed/canceled, billing date, retry count, error), by its Shopify subscription id. GET /vendor/purchase-state/{shopifySubscriptionId}/bills.
smartrr_list_customersList Smartrr customers (subscribers) with email, name, phone, order count, total spent and custom attributes. Search by email fragment or filter by Shopify customer id. GET /vendor/customer-relationship.
smartrr_list_ordersList orders Smartrr has synced from Shopify (subscription and one-time) with totals, status, financial and fulfillment status, tracking, items and customer. Filter by processed date or order label (e.g. #1001). GET /vendor/order.
smartrr_get_orderOne order by its Shopify order id (the `shopifyId` field in smartrr_list_orders, passed as shown). GET /vendor/orders/{shopifyId}.
smartrr_list_billsList billing attempts across all subscriptions with amount, status (pending, processing, succeeded, failed, canceled), billing date, retry count, error and the subscription and customer. Filter by billing date; `status` filters the returned page only (use page_size 100 and next_p
smartrr_get_bill_historyThe audit trail of one bill: every status change, retry and error. GET /vendor/bill/{billId}/history.
smartrr_list_selling_plan_groupsThe store's subscription programs (selling plan groups) and their plans: name, options, delivery and billing frequency, discounts. GET /vendor/selling-plan-group.
smartrr_list_cancellation_reasonsThe cancellation reasons configured in Smartrr (id, type, text, action, retention discount). Use an `id` as reason_id when cancelling a subscription. GET /vendor/cancellation-reasons.
smartrr_get_analyticsActive subscription count and active subscriber count for each day in a date range. GET /vendor/analytics-simple.
smartrr_pause_subscriptionWRITE: pause a customer's subscription until a date: no orders or charges are created while it is paused, then it resumes on that date. Reverse it with smartrr_resume_subscription. Takes the customer id and subscription id from smartrr_list_subscriptions. PUT /vendor/customer/{cu
smartrr_resume_subscriptionWRITE: reactivate a paused or cancelled subscription; the customer will be billed on next_billing_date and every cycle after. Customer-facing: it restarts charges to the customer's card. PUT /vendor/customer/{customerId}/purchase-state/{subscriptionId}/activate.
smartrr_cancel_customer_subscriptionWRITE, DESTRUCTIVE: cancel a customer's subscription in the merchant's store (this is the customer's Smartrr subscription, not your usefulapi plan). It stops all future orders and charges; the reason may trigger Smartrr's configured cancellation emails or actions. It can be undon
smartrr_skip_orderWRITE: skip one scheduled order of a subscription (no order and no charge for that cycle; the schedule moves on). `date` is the scheduled order date to skip; omit it to skip the next one. Reverse with smartrr_unskip_order. PUT /vendor/customer/{customerId}/purchase-state/{subscri
smartrr_unskip_orderWRITE: restore a previously skipped order of a subscription, so it is billed and shipped again. `date` is the skipped order date; omit it to restore the earliest skip. PUT /vendor/customer/{customerId}/purchase-state/{subscriptionId}/unskip.
smartrr_set_next_billing_dateWRITE: change the date on which a subscription is next billed and its order created. Customer-facing: the customer is charged on the new date. PUT /vendor/customer/{customerId}/purchase-state/{subscriptionId}/next-billing-date.
smartrr_retry_billWRITE, CHARGES THE CUSTOMER: retry a billing attempt now. If it succeeds the customer's saved payment method is charged for the bill amount and the order is created. Check the bill with smartrr_list_bills first; do not retry a succeeded bill. Not idempotent: each call can charge

Common questions
Is Smartrr MCP by usefulapi safe?
It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed –, and the latest version (1.15.3) reached the registry yesterday.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
What can I use instead?
In the same category: Spree Commerce: open-source B2B and marketplace ecommerce, Stripe MCP, MCP Cn Commerce
