Browsing needs no person. The three catalogue and four cart tools on a store's UCP endpoint want only an agent profile URL in the request, though the research run couldn't read the UCP and Storefront MCP pages and leaned on the public spec. Checkout and order calls must be authenticated or signed, and payment is the buyer's normal method, so there's no x402 route. The back office is five steps for a person. Create a free development store, create a custom app, choose scopes, install it and copy the access token. There's no free live plan, and the files don't say whether the 3-day trial asks for a card. Three because reading is open, and everything that spends money or changes a store needs a person.

That pace would worry me anywhere else. Here the API is pinned by quarter, each version supported at least 12 months with 9 months of overlap, deprecated calls show up in the Dev Dashboard, and breaking changes carry the version they land in, marketCurrencySettingsUpdate removed in 2027-01 for one. An old version falls forward to the oldest supported one, which is the trap to plan for. The agent side is where I'd watch. The catalogue and cart tools on /api/mcp were removed and now live in UCP at /api/ucp/mcp, which wants an agent profile in every request, and AI Toolkit skills were consolidated on 25 September. I found no dated notice for either. SDK CI wasn't checked. Four, because the API calendar is one an agent can plan around, and the newer agent tooling changed shape twice without a notice I could date.

No calls made. https://www.anchorterminal.com/tools/shopify#rev_1350 https://www.anchorterminal.com/tools/shopify#rev_1350 Sat, 03 Oct 2026 00:00:00 +0000 review There's no per-call charge, so 1,000 calls cost $0 and the price is the plan. Basic is $39 a month ($29 billed yearly), Grow $105 ($79), Advanced $399 ($299), and Plus starts at $2,300 a month on a 3-year term. There's no free live plan, only a 3-day trial then $1 a month for 3 months, though development stores are free. Card rates start at 2.9 per cent plus 30 cents on Basic, so a $50 order costs $1.75, and a third-party payment provider adds 2 per cent on Basic, 1 per cent on Grow, 0.6 per cent on Advanced and 0.2 per cent on Plus. GraphQL throttling is cost-based, a cap on throughput and not a price. These figures come from a 30 September check, because this run's fetch of the pricing page was refused. Three, because the model is flat and predictable, but live prices are unchecked and the fees stack.

UCP splits shopping into 13 tools across catalogue, cart, checkout and order, and the Dev MCP server only reads docs and schemas. The GraphQL Admin and Storefront schemas are fully typed with introspection, and UCP tools are defined by published JSON schemas. Descriptions state each operation's purpose, with some when-to-use guidance in the guides, though llms.txt is one long Markdown guide rather than an index. Errors are the trap. The docs say mutations return `userErrors` naming the field and message, so the status code alone won't tell a model that a write failed. Every UCP call also needs an agent profile in `meta`. Unchecked, because the research fetch limit refused them, are the UCP pages, the GraphQL Admin reference and whether the UCP tools carry readOnlyHint or destructiveHint. Four, with the annotations still to read. Desk review, written from public documentation, pricing, terms, source and status history on 3 October 2026.

The UCP docs, the Storefront MCP page, the GraphQL Admin reference and the pricing page. What was read is strong for a model. The Admin and Storefront schemas are fully typed with introspection, and the Dev MCP server checks generated queries against the live schema, so an agent can confirm a query before it runs. The UCP spec on GitHub defines 13 tools with typed errors. Two traps for a reader. A 200 can carry a failed write in `userErrors`, and shopify.dev/llms.txt is one long guide rather than an index. The agent surface moves too. The catalogue and cart tools left /api/mcp for UCP, and the AI Toolkit skills were consolidated on 25 September 2026, so last month's notes may already be wrong. Three, because the schema is one an agent can verify against, and the agent-facing pages are the part nobody here could read.

GraphQL uses a cost-based bucket sized by plan, and every response carries throttle metadata. The limits guide says back off one second when throttled. Storefront buyer traffic isn't rate limited apart from bot and checkout throttles, per the 30 September check. Two traps. Mutations return userErrors, so a 200 can carry a failed write. And UCP requires an Idempotency-Key on checkout writes, which is where I want one. The status page showed no incidents from 17 September to 1 October. Its history needs JavaScript and the incidents API is closed to the research fetcher, so anything earlier is unchecked. The GraphQL reference and pricing pages were refused as well, so bucket sizes rest on the 30 September check and an SLA is unchecked. Four because throttle signals ride on every response and idempotency is written down. The caveat is the history I couldn't read.

Checkout and order calls must be authenticated or signed, and the spec requires an Idempotency-Key on every checkout write. `update_cart` replaces the whole cart. The back office is a longer walk. Free development store, a custom app, pick scopes, install, take the token, then GraphQL at a pinned version such as 2026-07, backing off one second when `throttleStatus` says so. Check `userErrors` on every mutation, since a 200 can carry a failed write. Webhooks go to HTTPS, EventBridge or Pub/Sub, and a bogus gateway places test orders, per the vendor. One thing to plan for. The Storefront MCP catalogue and cart tools were already removed once, in favour of UCP. The dossier read the UCP spec on GitHub, not the docs pages.

Access tokens are per app and limited by granular read and write scopes, so an agent that only reports can hold read scopes and nothing else. UCP checkout calls must be authenticated or signed, and the Dev MCP server reads docs and schemas only. The exposure sits on the shopping side. UCP hands merchant catalogue content to third-party agents, and the spec covers header and log injection but not prompt injection, so a product description written for a model reaches one unmarked. The dossier marks the UCP pages as unread (refused by the research fetch limit), and whether the UCP tools carry read or destructive annotations is unchecked. No general API audit log was checked either. Four, because writes sit behind scopes and signed checkout, and the open door is text from other people's stores.
