Storefront Check tools (4)
write = sends, deletes, buys or postsaudit_product_feedFreeReads a Shopify store's public products.json and reports what would break a Google Merchant Center or Meta catalogue feed: missing barcodes, absent weights, unpriced or unavailable variants, and thin descriptions. Shopify-only, because products.json is a Shopify endpoint.
check_agent_readinessFreeDetermines whether an AI agent can actually discover and parse a store: whether robots.txt permits each major AI crawler by name, whether a sitemap, llms.txt, product feed or MCP endpoint exists, and whether the catalogue is machine readable. Use this when asked why a store never appears in AI assistants or agent shopping results.
check_structured_dataFreeParses every JSON-LD block on a page and reports the schema.org types found, blocks that fail to parse, and whether the types a shopping agent looks for are present. Point it at a product page to check Product and Offer markup, or at a homepage to check Organization and WebSite.
detect_tracking_tagsFreeReads a public storefront and reports every advertising, analytics and marketing tag visible in its HTML, with the actual measurement ids. It then verifies each Google id against Google Tag Manager, because an id Google does not recognise returns 404 and silently stops gtag from initialising, which means a campaign can spend for months while recording zero conversions. Use this to explain why conversion tracking is wrong, or to see what a store you have no access to is running.

What the publisher says
From the Storefront Check repository's README, as published. We do not edit it. Read it on GitHub
Profitpather Tools
Open MCP servers for ecommerce operations, hosted on Cloudflare Workers at https://tools.profitpather.com. No account, no API key, no sign-up.
Each server is namespaced by slug under one hostname, so adding a server is a registry entry rather than a new domain.
All four are published in the official MCP Registry under com.profitpather.tools/.
A theme runs through all of them: each one distinguishes what it knows from what it cannot see, and says so in the response. ShipRate refuses to rank across currencies because the data has no exchange rate. Business Days reports provider disagreement instead of resolving it. Storefront Check carries a not_observable list on every tool. US Tariff Lookup states what its figures exclude. A confidently wrong tool is worse than no tool.
ShipRate AU
Australian parcel shipping, quoted from two independent sources in one call.
- quotedomesticau - domestic rates from both sources
- quoteinternationalfrom_au - outbound international rates
- lookupaupostcode - postcode to suburb and state, or the reverse
- calculatecubicweight - the weight you will actually be billed on
- listgoodscategories - the fixed category enum the commercial source accepts
The two sources are not interchangeable, and the server never pretends they are. Australia Post prices come from the PAC API and are retail: a business on an eParcel or contract account pays materially less. The commercial panel is pre-negotiated pricing, a different class entirely. Every rate carries a pricing_basis saying which it is, so a lower number is never mistaken for a better carrier.
Two further rules the server holds to:
rate, so when more than one currency comes back the list is deliberately left unsorted and sortedbyprice is false. Nothing is summed either.
- It will not rank across currencies. The upstream data carries no exchange
always says what was missing and why, so an empty list is never silently presented as "no options exist".
- A source that quoted nothing is reported, not hidden. source_notes
calculatecubicweight exists because carriers bill on whichever is greater, actual or volumetric weight. A 60x40x40cm parcel weighing 2kg is billed as 24kg under the Australia Post domestic convention. It returns every common divisor with the arithmetic shown, and states its assumptions rather than implying one number is authoritative.
Business Days
Public holidays and working-day arithmetic for 200+ countries, including state and province subdivisions.
- listpublicholidays - holidays in a country or region for a year
- checkbusinessday - is this date a working day, and what blocks it
- addbusinessdays - move N working days, skipping weekends and holidays
- crosscheckholidays - compare the national list across all providers
A language model's failure mode on calendar questions is confident wrongness, and a tool that is also confidently wrong adds nothing. So holiday data is read from three independent providers and disagreements are reported rather than resolved:
Providers are compared by date, never by name, since the same day is named differently by each. A disputed date arrives as a caveat attached to the answer, not as a confident single date.

Storefront Check: common questions
- Is Storefront Check MCP server safe?
- Yes, by our scan: it is graded A (91/100). Read the Storefront Check safety report
- How do I install Storefront Check?
- It runs remotely at tools.profitpather.com. Add it to Claude Code, Cursor, VS Code or Claude Desktop with the snippets above, or call it through the mcp.market gateway without installing anything.
- Does Storefront Check need an API key?
- Not as far as the registry entry and our scan can tell: no credentials are declared or required.
- Is Storefront Check maintained?
- The last commit was 20 days ago (2026-10-15). The latest release is v1.0.0.
- Is Storefront Check up?
- 100% of our last 28 checks got an answer. We check remote servers about four times a day.
- How does Storefront Check compare with other MCP servers?
- safety score 91/100 (higher than 85% of 48,255 servers); tools 4 (the typical server has 7); tools that change things 0% (typical: 0%. Fewer write tools means less an agent can break). Full comparison.
