This skill should be used when adding payments, subscriptions, billing, or pricing to a SaaS — Stripe integration, checkout, plans, the customer portal, webhooks, or deciding a pricing model. Trigger phrases include "add Stripe", "accept payments", "add a subscription", "charge users", "pricing tiers", "checkout", "billing portal", "handle the webhook", "set up plans", "monetize", "free trial". It wires Stripe correctly (checkout to webhook to fulfillment) and sets a sane pricing model.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Payments This skill turns an app into a SaaS that actually collects money — and does it without the classic bugs (fulfilling on the client redirect, double-granting access, unverified webhooks). Analogy: the checkout redirect is the customer saying "I'll pay." The **webhook** is the bank confirming the money arrived. You ship the product when the bank confirms, not when the customer promises. Trusting the redirect is shipping on a promise. ## The Stripe MCP split (read this first) A Stripe MCP may be available (`mcp__stripe__*`). It is **control-plane only**: it creates products, prices, and payment links, and reads/updates subscriptions and customers. It **cannot** create Checkout Sessions or process webhooks. So the architecture is hybrid: - **Delegate the catalog to the MCP** — use it to create products, prices, and one-off **payment links** (the lowest-effort path for an MVP). - **Embed the integration code** — Checkout Session creation, the webhook handler, and fulfillment must live in your shipped code, because the MCP can't do them. If no MCP is present, create the catalog by hand in the Stripe dashboard or via the SDK; everything else below is identical. …

How to install
mdr add martinolivero/saas-builder/payments@sha256:6afbc45de0a99c0bThe line at the top of this page pins the label git:20261007.f2beefe, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
