What it does

Moonpay Commerce is an agent skill from moonpay/skills. Browse Shopify stores, search products, manage a cart, and checkout with crypto via Solana Pay. No login required.

Its SKILL.md is about 730 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Sales & Support, covering E-commerce operations. It works with Solana, Shopify and Circle USDC. The repository describes itself as: Skills for AI agents to move money — on-ramps, swaps, wallets, deposits, and more via the MoonPay CLI. The licence is MIT.

When your agent uses it

  • Tasks that involve E-commerce operations

Example prompts

  • “/moonpay-commerce”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Browse stores: mp commerce store list
  2. Search: mp commerce product search --store ryder.id --query "ryder"
  3. Add to cart: mp commerce cart add --store ryder.id --variantId "gid://shopify/ProductVariant/51751218774319" --quantity 1
  4. Check cart: mp commerce cart retrieve --store ryder.id --cartId
  5. Checkout: mp commerce checkout --wallet main --store ryder.id --cartId --chain solana --email buyer@example.com --firstName John…

What it can do on your machine

Read from SKILL.md and the folder at commit aa672ab. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Moonpay Commerce loads about 728 tokens when it runs. Until then it costs about 33 tokens; SKILL.md has 274 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~33
When it runs · the whole SKILL.md, loaded when a task matches
~728

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Shop with crypto

Goal

Browse Solana Pay-enabled Shopify stores, add items to a cart, and pay with crypto. The entire flow runs from the CLI — no browser needed.

Commands

List stores
bash
mp commerce store list
Search products
bash
mp commerce product search --store <store> --query <search-term>
Get product details
bash
mp commerce product retrieve --store <store> --productId <product-id>
Add item to cart
bash
mp commerce cart add \
  --store <store> \
  --variantId <variant-id> \
  --quantity <number> \
  --cartId <cart-id>  # omit to create a new cart
View cart
bash
mp commerce cart retrieve --store <store> --cartId <cart-id>
Remove item from cart
bash
mp commerce cart remove --store <store> --cartId <cart-id> --lineId <line-id>
Checkout and pay
bash
mp commerce checkout \
  --wallet <wallet-name> \
  --store <store> \
  --cartId <cart-id> \
  --chain solana \
  --email <buyer-email> \
  --firstName <first> \
  --lastName <last> \
  --address <street-address> \
  --city <city> \
  --postalCode <zip> \
  --country <country-name>

Example flow

  1. Browse stores: mp commerce store list
  2. Search: mp commerce product search --store ryder.id --query "ryder"
  3. Add to cart: mp commerce cart add --store ryder.id --variantId "gid://shopify/ProductVariant/51751218774319" --quantity 1
  4. Check cart: mp commerce cart retrieve --store ryder.id --cartId <id-from-step-3>
  5. Checkout: mp commerce checkout --wallet main --store ryder.id --cartId <id> --chain solana --email buyer@example.com --firstName John --lastName Doe --address "123 Main St" --city Amsterdam --postalCode 1011 --country Netherlands

How it works

  1. Stores expose a Shopify MCP endpoint for browsing and cart management
  2. cart add creates or updates a cart (no auth needed, cart ID is the handle)
  3. checkout calls the API to start a Helio payment, signs the transaction locally, and submits
  4. Helio pays gas — the buyer only pays the item price in USDC
  5. Returns a transaction signature and order confirmation URL

Tips

  • Run cart add multiple times to add different items — pass the --cartId from the first call
  • Use product search to find variant IDs — each variant has a Shopify GID
  • The --country flag takes full country names (e.g. "United States", "Netherlands")
  • Checkout takes 30-90 seconds — the API automates the Shopify checkout flow
  • Currently supports Solana chain only for payment
  • moonpay-auth — Set up a local wallet for signing
  • moonpay-check-wallet — Check USDC balance before checkout
  • moonpay-swap-tokens — Swap tokens to get USDC for payment
