What you can do with Smartrr in Claude and ChatGPT

For Shopify merchants who sell subscriptions with Smartrr.

Find subscriptions with failed bills

The AI lists billing attempts with amount, status, retry count and error, and shows the subscription and customer behind each failed one.

List subscriptions that renew soon

The AI lists subscriptions filtered by status and next billing date, with line items, selling plan and customer.

Review the history and orders of a customer's subscription

The AI finds a customer, lists their subscriptions, and reads the recent events (pause, skip, cancel, billing failures) and orders of one subscription.

Track active subscriptions and subscribers per day

The AI reads the number of active subscriptions and active subscribers for each day in a date range, so you can see the trend.

Pause, resume or cancel a subscription

The AI pauses a subscription until a date, resumes a paused or cancelled one, or cancels it with a cancellation reason.

Changes data

Skip an order, move a billing date or retry a failed bill

The AI skips a scheduled order, sets a new next billing date, or checks the bills and retries a failed one. A retry charges the customer.

How do I connect Smartrr?

Before you connect

The login page asks for your Smartrr access token.

Create it in your Shopify admin → Apps → Smartrr → Integrations → Add Key. Name it, then set its permissions: read access for everything you want the assistant to see, and write access only if it should pause, skip, cancel or retry bills. Your token is used only to call the Smartrr API on your behalf; it is never shown to anyone.

Claude claude.ai · Desktop

Open Customize → Connectors, then click + Add → Add custom connector.

https://smartrr.usefulapi.io/mcp
ChatGPT opens the login page: enter your Smartrr access token.
In Plugins, install Smartrr, then choose it in a chat.

No Add custom MCP server option? It depends on your account or workspace settings: see OpenAI's guide.

Claude Code

Run this command, then run /mcp in Claude Code to log in:

claude mcp add --transport http smartrr https://smartrr.usefulapi.io/mcp

Cursor

Add to Cursor or add this to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "smartrr": {
      "url": "https://smartrr.usefulapi.io/mcp"
    }
  }
}

VS Code

Add to VS Code or add this to .vscode/mcp.json:

{
  "servers": {
    "smartrr": {
      "type": "http",
      "url": "https://smartrr.usefulapi.io/mcp"
    }
  }
}

Codex

Run these commands. The second one opens the login page:

codex mcp add smartrr --url https://smartrr.usefulapi.io/mcp

codex mcp login smartrr

Other clients

Windsurf, Cline, Zed and other MCP clients: add this URL as a remote MCP server (Streamable HTTP). The client then opens the login page in your browser.

https://smartrr.usefulapi.io/mcp

Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your Smartrr access token. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.

Pricing

Plan	Price	Limit
Free	$0	50 tool calls / month
Proper user	$9/mo · $90/yr	10,000 tool calls / month
Pro+per user	$39/mo · $390/yr	100,000 tool calls / month

Each paid plan covers this Smartrr server only. Ask your AI to run smartrr_upgrade and choose Pro or Pro+, billed monthly or yearly (it returns a Stripe Checkout link). If you already have Pro, ask to change it to Pro+. The change requires your confirmation, keeps your billing interval and charges the price difference for the rest of the period immediately. Cancel any time with smartrr_cancel_subscription: your paid plan continues to the end of the paid period, with no refund for the current period, and asking to resume the same plan with smartrr_upgrade before then undoes the cancel. Or write to support@usefulapi.io.

Pause a subscriptionsmartrr_pause_subscription
WRITE: 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.
Resume a subscriptionsmartrr_resume_subscription
WRITE: 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.
Cancel a customer's subscriptionsmartrr_cancel_customer_subscription
WRITE, 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 undone only with smartrr_resume_subscription. Get reason_id from smartrr_list_cancellation_reasons.
Skip a subscription ordersmartrr_skip_order
WRITE: 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.
Unskip a subscription ordersmartrr_unskip_order
WRITE: 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.
Set next billing datesmartrr_set_next_billing_date
WRITE: change the date on which a subscription is next billed and its order created. Customer-facing: the customer is charged on the new date.
Retry a failed billsmartrr_retry_bill
WRITE, 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 again. Requires confirm=true.

Your usefulapi plan · 4

Usage status (free-tier meter)smartrr_usage_status
Report the caller's current usage: the plan, calls used this month, the limit of the plan (the free monthly cap or the Pro fair use limit), remaining, and whether the limit is reached. Read-only; does not count against the meter.
Request a missing featuresmartrr_request_feature
Tell usefulapi that the user needs something the Smartrr tools cannot do yet (a missing tool, field or filter). Call it only when the user asks for something none of the tools can do, and tell the user that you send the request. Do not call it for errors or for normal requests. Do not include personal data, credentials or customer records. Stored with the product name and the client type (for example Claude or Cursor), without the user's account. At most 5 requests per day. Does not count against the meter.
Upgrade to Pro or Pro+smartrr_upgrade
Get a paid plan for Smartrr (the free tier caps monthly usage). Pro: 10,000 tool calls a month, for normal use — plan "monthly" ($9/month) or "yearly" ($90/year, 2 months free). Pro+: 100,000 tool calls a month, for automations and heavy use — plan "plus" ($39/month) or "plus_yearly" ($390/year). Without a plan it returns both Pro and Pro+, each with a payment link, for the user to choose; with a plan, one link. An existing Pro subscription changes to Pro+ in place: call without confirm first, as the reply states the exact charge for this account (the price difference for the rest of the period, or in a free Pro trial the full Pro+ price, as the trial ends); then call with confirm: true. Cancel any time: the plan then runs to the end of the paid period, so it also suits a one-time job. A link opens Stripe Checkout in the browser; after payment the account upgrades automatically. Does not count against the meter.
Cancel the Pro subscriptionsmartrr_cancel_subscription
Cancel the caller's Smartrr Pro subscription at the end of the paid period (no refund for the current period; Pro continues until then, then the free tier applies). Requires confirm: true. Run smartrr_upgrade later to undo the cancel before the period ends. Does not count against the meter.

FAQ

What can I do with Smartrr in Claude or ChatGPT?

Find subscriptions with failed bills. List subscriptions that renew soon. Review the history and orders of a customer's subscription. Track active subscriptions and subscribers per day. Pause, resume or cancel a subscription. Skip an order, move a billing date or retry a failed bill. See what you can do for the details.

Is this an official Smartrr product?

No. usefulapi is an independent service. It is not affiliated with or endorsed by Smartrr. The server calls the Smartrr API with your own Smartrr access, so it sees only the data that your account can see.

Can I connect Smartrr to Claude or ChatGPT?

Yes. In Claude, add this server's URL as a custom connector. In ChatGPT, add it as a custom MCP server in Plugins. Then log in once. Cursor, VS Code, Claude Code and Codex work too. See the setup steps.

What do I need to connect?

The login page asks for your Smartrr access token. See Before you connect for where to find it.

Do I put my Smartrr key or an Authorization header in the client config?

No. Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your Smartrr access token. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.

How do you keep my Smartrr credentials?

The login stores them encrypted in the authorization grant of your connection. The server uses them to call the Smartrr API for you and to derive a private account id for usage metering. usefulapi does not show them on any page or in any reply. To stop all access, remove the connector and change or delete these credentials in Smartrr.

Can the AI change my Smartrr data?

Yes, if you approve it. 7 of the 21 Smartrr tools can create or change data. The other 14 are marked read-only. Most MCP clients ask you to approve a tool call before it runs.

What does it cost?

The Free plan gives 50 tool calls / month. Pro costs $9/mo or $90/yr, with 10,000 tool calls / month. Pro+ costs $39/mo or $390/yr, with 100,000 tool calls / month. Each subscription covers this Smartrr server only. Cancel any time: your paid plan then runs to the end of the paid period. Run smartrr_usage_status to see how many calls you used.

How do I subscribe or cancel?

Ask the AI to run smartrr_upgrade and choose Pro or Pro+, billed monthly or yearly: it returns a Stripe Checkout link. If you already have Pro, ask to change it to Pro+. After you confirm, your existing subscription changes in place, keeps its billing interval and charges the price difference for the rest of the period immediately. To cancel, run smartrr_cancel_subscription. Your paid plan continues to the end of the paid period.

What if a Smartrr tool that I need is missing?

Tell the AI what you wanted to do. It can send the request with smartrr_request_feature. We store the text with the server name, the type of AI client and the tool you tried, not with your account, and read every request when we plan new tools. You can send up to 5 requests per day.

Which AI clients can I use?

Any client that supports remote MCP servers (Streamable HTTP) with OAuth login: Claude (web and desktop), Claude Code, ChatGPT, Codex, Cursor, VS Code, Windsurf and others.

This is a Model Context Protocol endpoint — meant to be connected from an AI client, not opened in a browser. An invalid_token response at the URL is the auth gate working as designed; clients authenticate automatically.
