create_checkout

Create a hosted CHECKOUT LINK for a digital product / software / course through a merchant-of-record platform (the MoR is the seller and remits global sales tax / VAT). Returns checkout_url for the buyer to pay. One primitive across eight providers — pick with provider. item = the catalog id on that platform: Paddle price_id (pri_...), Lemon Squeezy variant_id (numeric, also needs store_id), Polar product_id (UUID), Whop plan_id (plan_...), Creem product_id (prod_...), Dodo product_id (pdt_...), FastSpring product path (also needs store_id = your storefront), 2Checkout catalog product code. Optional amount (major currency unit) is a custom price on Lemon Squeezy and drives the owner policy gate everywhere. Money flows buyer -> MoR -> merchant; this server never touches funds. Capabilities differ per provider (see per-field notes and INSTRUCTIONS). Credential headers (set once in your MCP client, per-request, never stored): x-mor-provider (paddle | lemonsqueezy | polar | whop | creem | dodo | fastspring | twocheckout; or pass the provider argument) + x-mor-key (that platform's API key: Paddle pdl_..., Lemon Squeezy API key, Polar polar_oat_..., Whop key, Creem creem_test_..., Dodo key, FastSpring "username:password" for HTTP Basic, 2Checkout "MERCHANT_CODE:SECRET_KEY") + x-mor-env (sandbox/test = default no real money; prod/live = real money & real tax). Owner-policy headers x-agentpay-max-amount / x-agentpay-approval-above / x-agentpay-allowed-tools also apply.

Parameters9

provider	string	optional	Merchant-of-record platform (or set the x-mor-provider header). paddle \| lemonsqueezy \| polar \| whop \| creem \| dodo \| fastspring \| twocheckout.
item	string	required	The item id to sell. Paddle = price_id (pri_...) to bill the catalog price, OR product_id (pro_...) together with amount + currency to charge a CUSTOM price (donations, pay-what-you-want, variable services); Lemon Squeezy = variant_id (numeric); Polar = product_id (UUID); Whop = plan_id (plan_...); Creem = product_id (prod_...); Dodo = product_id (pdt_...); FastSpring = product path.
store_id	string	optional	Required by Lemon Squeezy (your Store id) and FastSpring (your storefront, e.g. "yourstore" -> yourstore.onfastspring.com, used to build the hosted URL). Ignored by Paddle / Polar / Whop / Creem / Dodo.
quantity	integer	optional	Quantity (default 1). Supported by Paddle, Lemon Squeezy, Creem (units), Dodo, FastSpring; Polar and Whop checkouts are single-item.
amount	number	optional	Optional price in the MAJOR currency unit (e.g. 19.99). Paddle: a custom price when item is a product_id (pro_...) — also send currency. Lemon Squeezy = custom_price override. Other providers use the catalog price (amount only drives the owner policy gate).
currency	string	optional	ISO currency code (e.g. TWD, USD, JPY). Required by Paddle when item is a product_id (pro_...) and amount is a custom price. Zero-decimal currencies (JPY, KRW, VND, CLP, ISK) are converted correctly.
customer_email	string	optional	Optional buyer email to pre-fill on the checkout. Recommended for Dodo (its create requires a customer email).
country	string	optional	Dodo ONLY: 2-letter billing country code for the required billing address (default US; the buyer can change it on the hosted page). Ignored by other providers.
success_url	string	optional	Optional https URL to send the buyer to after payment. Used by Polar (success_url), Lemon Squeezy (redirect), Whop (redirect_url), Creem (success_url), Dodo (return_url). Paddle sets this in its dashboard, not per call.

issue_refund

Refund an order through the merchant-of-record platform. Capability differs by provider: Paddle = FULL refund only (POST /adjustments; pending_approval on production) — do NOT pass amount.

cancel_subscription

Cancel a subscription on the merchant-of-record platform. Behaviour differs: Paddle = cancel immediately or at next_billing_period (set immediately). Dodo = same (immediately -> cancelled now, else at period end). Creem = same (immediately -> now, else scheduled to period end).

Returns the unified subscription status. Credential headers (set once in your MCP client, per-request, never stored): x-mor-provider (paddle | lemonsqueezy | polar | whop | creem | dodo | fastspring | twocheckout; or pass the provider argument) + x-mor-key (that platform's API key: Paddle pdl_..., Lemon Squeezy API key, Polar polar_oat_..., Whop key, Creem creem_test_..., Dodo key, FastSpring "username:password" for HTTP Basic, 2Checkout "MERCHANT_CODE:SECRET_KEY") + x-mor-env (sandbox/test = default no real money; prod/live = real money & real tax).
