Review Zylvie coupons, sales transactions and subscriptions. For digital sellers reviewing sales and subscriptions in Zylvie. Hosted by usefulapi — connect from Claude, ChatGPT, Cursor, or any MCP client.
Team and Enterprise: an Owner adds the connector for the organization first.
Run this command, then run /mcp in Claude Code to log in:
Add to Cursor or add this to ~/.cursor/mcp.json:
{
"mcpServers": {
"zylvie": {
"url": "https://zylvie.usefulapi.io/mcp"
}
}
}Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"zylvie": {
"type": "http",
"url": "https://zylvie.usefulapi.io/mcp"
}
}
}No Add custom MCP server option? It depends on your account or workspace settings: see OpenAI's guide.
Run these commands. The second one opens the login page:
Other MCP clients (Windsurf, Cline, Zed and more): add the URL as a remote MCP server (Streamable HTTP). The client then opens the login page in your browser. Do not add an Authorization header: see Before you connect.
Compare active or archived coupon terms and redemption counts before planning your next promotion.
zylvie_list_coupons
Review transaction amounts, payment status and refund amounts for sales analysis. A transaction can be partially refunded while its refunded flag remains false.
zylvie_list_transactions
Identify active subscriptions scheduled to end and inspect their recorded cancellation and trial dates.
zylvie_list_subscriptions
The login page asks for your Zylvie API key.
Copy your API key from Zylvie Settings → API. This connector only reads data; it does not issue refunds, redeem license keys or change subscriptions. Billing and usage are per API key. Replacing the key creates a separate identity, with no automatic transfer of usage or a paid plan.
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 Zylvie API key. 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.
Turn on the Zylvie connector, then ask in plain words. The AI picks the tools.
| Tool | Type | What it does |
|---|---|---|
zylvie_get_account | read | Get authenticating account Authenticating account email and brand. Billing identity is per API key, not this email or brand. Read-only. |
zylvie_list_coupons | read | List coupons All active coupons, or archived coupons when archived is true, with discount terms and redemption counts. This list is not paginated. Read-only. |
zylvie_list_transactions | read | List transactions Transaction amounts, payment/refund status, buyer name/email and product summaries, newest first. Amounts are in major currency units; refunded false can include partial refunds. Excludes addresses, phone/card/bank details and custom fields. Read-only. |
zylvie_list_subscriptions | read | List subscriptions Subscription status, amount, cancellation/trial dates, product and buyer name/email, newest first. Amounts are major currency units, unlike the separate verify-subscription API. An active subscription may have cancel_at set. Excludes addresses, phone/card/bank details and custom fields. Read-only. |
zylvie_usage_status | Usage status (free-tier meter) 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. | |
zylvie_request_feature | Request a missing feature Tell usefulapi that the user needs something the Zylvie 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. | |
zylvie_upgrade | Upgrade to Pro (unlimited*) Get Pro: unlimited tool calls (fair use limit: 10,000 a month) on Zylvie (the free tier caps monthly usage). Plans: "monthly" — $9/month; "yearly" — $90/year (2 months free). Cancel any time: Pro then runs to the end of the paid period, so it also suits a one-time job. *A fair use limit applies. For heavy use (near Pro's limit): "plus" or "plus_yearly" — Pro+, $39/month or $390/year, unlimited tool calls (fair use limit: 100,000 a month); an existing Pro subscription changes to Pro+ in place (needs confirm: true; the price difference for the rest of the period is charged at once). Otherwise returns a short link to open in your browser (it opens Stripe Checkout); after payment the account upgrades automatically. Does not count against the meter. | |
zylvie_cancel_subscription | Cancel the Pro subscription Cancel the caller's Zylvie 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 zylvie_upgrade later to undo the cancel before the period ends. Does not count against the meter. |
| Plan | Price | Limit |
|---|---|---|
| Free | $0 | 50 tool calls / month |
| Proper API key | $9/mo · $90/yr | Unlimited* |
*Pro fair use limit: 10,000 tool calls a month on this server. For more, write to [email protected].
Pro covers this Zylvie server only. Subscribe with zylvie_upgrade (it returns a Stripe Checkout link). Cancel any time with zylvie_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running zylvie_upgrade before then undoes the cancel. Or write to [email protected].

No. usefulapi is an independent service. It is not affiliated with or endorsed by Zylvie. The server calls the Zylvie API with your own Zylvie access, so it sees only the data that your account can see.
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.
The login page asks for your Zylvie API key. See Before you connect for where to find it.
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 Zylvie API key. 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.
The login stores them encrypted in the authorization grant of your connection. The server uses them to call the Zylvie 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 Zylvie.
All 4 Zylvie tools are marked read-only.
The Free plan gives 50 tool calls / month. Pro costs $9/mo or $90/yr, with unlimited tool calls (fair use limit: 10,000 tool calls a month), for this Zylvie server only. Cancel any time: Pro then runs to the end of the paid period. Run zylvie_usage_status to see how many calls you used.
Ask the AI to run zylvie_upgrade: it returns a Stripe Checkout link. To cancel, run zylvie_cancel_subscription. Pro continues to the end of the paid period.
Tell the AI what you wanted to do. It can send the request with zylvie_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.
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.
