Paddle Catalog Setup

Create Paddle products and prices

When to use this skill

The user is starting a Paddle integration and their account doesn't yet have the products and prices that other Paddle skills (checkout-web, pricing-pages, sandbox-testing, webhooks) depend on. Use this skill to create them.

This is typically a one-time setup per project. Once the catalog exists, you don't revisit this skill — only when the user wants to add new products or prices.

What you're modeling — confirm with the user first

Before creating anything, agree on these with the user. Do not guess.

• Products vs prices.
  • A product is what's sold ("Pro plan", "Lifetime license").
  • A price is how it's charged ($10/month, $96/year, $999 one-off).
  • One product can have many prices — typically one per billing interval.
  • Prices can have price overrides for different markets.
• Tax category (per product). Pick from the table below. Default to saas for software-as-a-service or standard for everything else, and surface the choice after creating for the user to confirm. Users must get approval for other tax categories in the dashboard.
• Billing model (per price). Recurring (subscription) requires a billing cycle (e.g. month / year) — billing_cycle in MCP body params, billingCycle in the SDK; one-time prices omit it. Trial periods are subscription-only — the API rejects them on one-time prices.
• Currency and amounts. The unit price amount (unit_price.amount in MCP, unitPrice.amount in the SDK) is a string in lowest currency units. Cents for USD/EUR/GBP ("1000" = $10.00). Whole units for the zero-decimal currencies — JPY, KRW, and CLP ("1200" = ¥1,200 / ₩1,200 / CLP$1,200, not ¥12 etc.). CLP has historical centavos but Paddle treats it as zero-decimal for everyday transactions.
• Environment. Default to sandbox during development. Sandbox and production are completely separate — pro_... and pri_... IDs from one don't exist in the other. Ask the user before targeting production.

IDs look like pro_01h... (products) and pri_01h... (prices). You'll need the price IDs to wire into the user's app, so capture them after creation.

Tax categories

Choose your method

Pick the highest-ranked method that's available to you:

1. Paddle MCP server — if search and execute tools from a paddle-sandbox (or paddle-live) MCP server are in your toolset, use them. Fastest, no code for the user to run, results immediate. Always prefer this.
2. Node SDK seed script — if MCP isn't available but the user has a PADDLE_API_KEY (or can generate one), generate a seed script for the user to run. Repeatable, version-controlled.
3. Dashboard (manual) — if neither is workable, dictate click-by-click steps for the user to follow.

If a method fails midway (e.g. SDK call returns forbidden because the API key lacks permissions), fall back to the next method rather than retrying.

If the user doesn't have a Paddle MCP server installed, surface it as a suggestion — point them at the Paddle MCP server install guide.

Method 1: Paddle MCP server

Check whether search and execute tools from paddle-sandbox (or paddle-live) are available to you. If yes, use them.

The Paddle MCP exposes three tools per server (search, execute, report_missing_tool). Workflow: call search to confirm the exact method name and parameter shapes, then call execute with an async function that calls client.<resource>.<operation>(...). Method paths are camelCase (client.clientTokens.create, client.pricingPreview.preview). Body params and response fields are snake_case (tax_category, product_id, unit_price, currency_code). Pagination is { pagination: { hasMore }, data: [...] } with { after: "<last_id>" } — not .next() / .hasMore. Chain multi-step workflows inside one execute; variables don't persist between calls. Hard caps: 50 API calls per execute, 30s timeout, 32KB code.

Default to paddle-sandbox unless the user has explicitly asked to target live.

1. Confirm the product details with the user (name, tax category, prices to create).
2. Call search with a query like "products create" and "prices create" to confirm the current method names and parameter shapes.
3. Call execute with one async function that creates the product and all its prices in a single call. Chaining inside one execute avoids round-trips and keeps related operations atomic.
4. Report all created IDs back to the user — they'll need to paste them into their app.

Example execute payload — one product, monthly + yearly prices, monthly with a trial:

async (client) => {
  const product = await client.products.create({
    name: "Pro",
    tax_category: "saas",
    description: "For scaling teams.",
  });
  const monthly = await client.prices.create({
    product_id: product.id,
    description: "Pro monthly USD",
    unit_price: { amount: "1000", currency_code: "USD" },
    billing_cycle: { interval: "month", frequency: 1 },
    trial_period: { interval: "day", frequency: 14 },
  });
  const yearly = await client.prices.create({
    product_id: product.id,
    description: "Pro yearly USD",
    unit_price: { amount: "9600", currency_code: "USD" },
    billing_cycle: { interval: "year", frequency: 1 },
  });
  return { product_id: product.id, monthly_id: monthly.id, yearly_id: yearly.id };
};

For a one-time price (lifetime license, etc.), drop billing_cycle and trial_period:

const lifetime = await client.prices.create({
  product_id: product.id,
  description: "Pro lifetime",
  unit_price: { amount: "29900", currency_code: "USD" },
});

For regional pricing, add unit_price_overrides — all snake_case, including the inner field names:

unit_price_overrides: [
  {
    country_codes: ["DE", "FR", "IT", "ES", "NL"],
    unit_price: { amount: "900", currency_code: "EUR" },
  },
  { country_codes: ["GB"], unit_price: { amount: "800", currency_code: "GBP" } },
  { country_codes: ["JP"], unit_price: { amount: "1200", currency_code: "JPY" } },
];

If the MCP search / execute tools aren't available, fall back to Method 2.

Method 2: Node SDK seed script

Use this when the user has (or can install) @paddle/paddle-node-sdk and a PADDLE_API_KEY. You write the script; the user runs it.

1. Confirm the user has PADDLE_API_KEY set in their environment. If not, point them to Paddle > Developer tools > Authentication in the sandbox dashboard and ask them to create one with at minimum the product.write and price.write permission scopes.
2. Add @paddle/paddle-node-sdk to the project (npm install @paddle/paddle-node-sdk), if not present.
3. Write a seed script and ask the user to run it once.
4. Capture the printed IDs from the output and use them to update the user's app config.

Template:

// scripts/seed-paddle-catalog.ts
import { Environment, Paddle } from "@paddle/paddle-node-sdk";

const paddle = new Paddle(process.env.PADDLE_API_KEY!, {
  environment: Environment.sandbox, // change to .production for live
});

async function seed() {
  const pro = await paddle.products.create({
    name: "Pro",
    taxCategory: "saas",
    description: "For scaling teams.",
  });

  const monthly = await paddle.prices.create({
    productId: pro.id,
    description: "Pro monthly USD",
    unitPrice: { amount: "1000", currencyCode: "USD" }, // 1000 cents = $10.00
    billingCycle: { interval: "month", frequency: 1 },
    trialPeriod: { interval: "day", frequency: 14 },
  });

  const yearly = await paddle.prices.create({
    productId: pro.id,
    description: "Pro yearly USD",
    unitPrice: { amount: "9600", currencyCode: "USD" },
    billingCycle: { interval: "year", frequency: 1 },
  });

  console.log(
    JSON.stringify({ productId: pro.id, monthlyId: monthly.id, yearlyId: yearly.id }, null, 2),
  );
}

seed().catch((e) => {
  console.error(e);
  process.exit(1);
});

Run it: npx tsx scripts/seed-paddle-catalog.ts.

One-time price (lifetime license, etc.) — drop billingCycle and trialPeriod:

await paddle.prices.create({
  productId: pro.id,
  description: "Pro lifetime",
  unitPrice: { amount: "29900", currencyCode: "USD" },
});

Regional overrides — add unitPriceOverrides:

unitPriceOverrides: [
  { countryCodes: ["DE", "FR", "IT", "ES", "NL"], unitPrice: { amount: "900", currencyCode: "EUR" } },
  { countryCodes: ["GB"], unitPrice: { amount: "800", currencyCode: "GBP" } },
  { countryCodes: ["JP"], unitPrice: { amount: "1200", currencyCode: "JPY" } },
],

If the script fails with forbidden or unauthorized, the API key lacks the required permission scopes — ask the user to regenerate it with product.write and price.write. If it fails because the user can't or won't install the SDK, fall back to Method 3.

Method 3: Dashboard (manual)

Last resort. Use when MCP and SDK paths are both blocked. Dictate the steps for the user to follow, then ask them to share the IDs.

Tell the user:

1. Sign in to the sandbox dashboard (or live if going to production).
2. Go to Paddle > Catalog > Products and click New product. Fill in:
   • Name — e.g. "Pro" (this is what users see in checkout).
   • Tax category — <the value you agreed on above>. Cannot be changed after a sale.
   • Description, icon — optional.
3. Save the product.
4. Inside the new product, click New price. Fill in:
   • Description — internal label (e.g. "Pro monthly USD").
   • Type — Recurring (subscription) or One-time.
   • Billing cycle (recurring only) — Monthly, Yearly, Weekly, Daily, or Custom.
   • Trial period (recurring only) — optional.
   • Amount — amount + currency (e.g. 10.00 USD).
   • Regional prices — optional overrides per market.
5. Save the price. Repeat for each price needed.
6. After all prices are created, copy the pri_... IDs from the price details panel and paste them back to me.

After the user shares the IDs, update their app config (constants file, env vars, or wherever you've decided price IDs live).

Verify

Whichever method you used, before declaring this skill complete:

1. Confirm the products and prices exist. Via MCP — one execute call: client.products.list({ include: ["prices"] }). Via SDK: paddle.products.list({ include: "prices" }). Or ask the user to check Paddle > Catalog > Products in the dashboard.
2. Confirm the IDs you reported match. Via MCP: client.products.get(productId, { include: ["prices"] }) for each new product (note productId is a positional path param). Via SDK: paddle.products.get(id). Check name + tax category.
3. Suggest the next step. Recommend the user complete checkout-web next, using one of the new price IDs, to confirm the catalog actually works in checkout.

Common pitfalls

• Creating in the wrong environment. Sandbox and production have completely separate catalogs. With the remote MCP, the server name determines the environment — paddle-sandbox for sandbox, paddle-live for production. paddle-sandbox authenticates with a pdl_sdbx_... API key; paddle-live authorizes with OAuth in the browser (or a live API key). With the SDK, Environment.sandbox vs Environment.production. Always confirm before creating.
• Confusing amount units. unit_price.amount (MCP) / unitPrice.amount (SDK) is a string in lowest currency units. "1000" is $10.00, not $1000. The zero-decimal currencies (JPY, KRW, CLP) are whole units — "1200" is ¥1,200 / ₩1,200 / CLP$1,200, not ¥12 etc.
• Forgetting the product ID on a price. client.prices.create() (MCP) and paddle.prices.create() (SDK) both require the parent product's ID — product_id in MCP body params, productId in SDK. Create the product first, capture its id, then pass to each price.
• Trial period on a one-time price. Not allowed — trials are subscription-only. The API rejects it. Drop trial_period (MCP) / trialPeriod (SDK) if there's no billing cycle.
• Recurring price with no billing cycle. Without billing_cycle (MCP) / billingCycle (SDK), the price is created as one-time. Always set { interval: "month", frequency: 1 } (or similar) for subscriptions.
• Mixing camelCase and snake_case in MCP execute code. Method paths are camelCase (client.clientTokens.create, client.pricingPreview.preview), but body params and response fields are snake_case (tax_category, product_id, unit_price, currency_code). The SDK is camelCase end-to-end — don't carry that convention into execute code, and don't carry the snake_case convention back into SDK code.
• Splitting dependent calls across multiple execute invocations. Variables don't persist between execute calls, so passing IDs requires returning them and re-passing on the next call. Chain dependent operations (product → prices → overrides) inside one async function and return the IDs at the end.
• Using regional overrides without a sensible base price. Customers in countries you didn't override see the base price auto-converted. Pick a base currency that's a reasonable fallback.
• Missing write permissions. The remote MCP inherits permissions from whatever it authenticated with. If client.products.create() returns forbidden on paddle-sandbox, the API key lacks product.write / price.write — ask the user to regenerate it from Paddle > Developer tools > Authentication with those scopes added. On paddle-live connected with OAuth, the connection starts read-only, so a write returning forbidden is expected until the user grants write permissions under Paddle > Connectors > MCP. Permissions there are capped by their Paddle user's role.
• Pasting IDs into the user's code without telling them. Always report new IDs back; let the user (or you, with their approval) commit the change explicitly.
