Catalog QA Desk in Claude
Product catalog checks. The MCP server is https://catalogqa.openkrill.app/mcp. No key. The steps below are only for Claude. A call to csv_import_preflight was checked against that server on 2026-10-01.
What this server answers
Check an online store's product catalog before you import it or send it to a shopping feed.
Ask "will this Shopify product CSV import cleanly?", "what would Google Merchant Center reject in my catalog?", "which products have no image alt text or a copied description?" or "write me a sheet that fixes the empty alt text".
Catalog QA Desk checks a Shopify product CSV against the import rules (required columns, handles, options, duplicate variants, prices, statuses, image URLs, barcodes mangled by a spreadsheet) and returns the rows that block the import and the ones that import wrongly, each with the fix.
It checks products for Google Merchant Center feed rules: missing or invalid barcodes (GTIN length and check digit), titles that are too long, promotional or in capitals, missing descriptions, links in descriptions and missing images.
It audits listing text: images without alt text, descriptions copied between products, thin descriptions and title problems; and it builds an advisory CSV of corrected titles and alt text for you to review and import yourself.
You can pass the CSV text (up to 2 MB), or a store address: the store's public product feed (/products.json, at most 5 pages of 250 products) is read once, after its robots.txt, only when you ask. Large stores often block that feed, and then a CSV is needed.
It does not use the Shopify admin API, does not log in to any store, changes nothing in a store and does not submit anything to Google. Nothing you send or read is stored, no catalog is kept or indexed, and there is no account; only a daily count of calls per tool is recorded.
What it can do
- Checks a Shopify product CSV before import and lists blocking rows and warnings, each with the fix
- Finds products Merchant Center would reject: bad or missing GTINs, long or promotional titles, empty descriptions
- Finds images without alt text, copied or thin descriptions and title problems
- Builds a CSV of corrected titles and alt text to review and import; changes nothing in the store
- Reads a store's public product feed once on request, after robots.txt, instead of a CSV
Tools
csv_import_preflight, Check a product CSV before import. Check the text of a Shopify product CSV against the import rules before it is imported. Use it for "will this CSV import?", "what is wrong with my product file?". Pass csv exactly as exported or edited, header row included, up to 2 MB. Returns blocking findings (Shopify rejects them or the import comes out wrong) and warnings, up to 200 each, every one with row, handle, rule and the fix, plus totals. Nothing is stored: the file or feed is used for this answer and dropped.merchant_feed_check, Check products for Merchant Center rules. Check products against Google Merchant Center feed rules: missing or invalid GTIN barcodes, long, promotional or all-capital titles, missing descriptions, links, images and brand. Use it for "what would Merchant Center reject?". Pass csv (a Shopify product CSV) or domain (a store address), not both. Returns a summary (products, no_gtin, bad_gtin, long_title, no_description) and up to 200 issues, one per product and rule, with detail. Domain mode reads the store's public product feed once after its robots.txt; a store that blocks it needs a CSV. The public feed has no barcodes, so in domain mode no_gtin and bad_gtin are null and GTINs are not checked; use a CSV for that. Nothing is stored: the file or feed is used for this answer and dropped.listing_text_audit, Audit product listing text. Audit the text of product listings: images without alt text, descriptions copied between products, descriptions that are too short and title problems. Use it for "which products have no alt text?", "are any descriptions duplicated?". Pass csv or domain, not both, and optionally min_words (default 20). Returns the four lists (each up to 100 entries) with totals before the cut. Domain mode reads the store's public product feed once after its robots.txt. Nothing is stored: the file or feed is used for this answer and dropped.listing_fix_sheet, Build a CSV of listing text fixes. Build a CSV of corrected titles and image alt text from a catalog, for the user to review and import. Use it for "write the alt text for my images", "fix the shouting titles". Pass csv or domain, not both; optional fixes (alt_text, title_whitespace, title_caps) and alt_text_template with {title}, {vendor}, {type}, {position}. Returns csv with only the rows that change (URL handle, Title, Product image URL, Image position, Image alt text), up to 200 rows, and counts. Advisory: nothing is changed in any store. Nothing is stored: the file or feed is used for this answer and dropped.
Add Catalog QA Desk in Claude
Claude connects to a remote MCP server as a custom connector. The connection is made from Anthropic's cloud, not from your laptop, so the server must be on the public internet. Catalog QA Desk is. These steps were checked against Claude's custom-connector article (updated 2026-08-11) and the Claude Code MCP docs on 2026-10-01.
On a Pro or Max plan:
- Open Customize, then Connectors.
- Select the plus button, then Add custom connector.
- Paste
https://catalogqa.openkrill.app/mcp. Leave Advanced settings empty: this server does not need an OAuth client id or secret. - Select Add. The connector is yours. Anthropic has not reviewed it, and it is not a Directory listing.
- In a conversation, open the plus button, then Connectors, and enable Catalog QA Desk. Ask: Will this Shopify product CSV import cleanly?
On Team and Enterprise, an Owner adds the connector first at Organization settings, then Connectors, then Add, then Custom, then Web, and pastes the same URL. Members then connect it from Customize. A Free plan can add one custom connector.
In Claude Code, add it from the project directory:
claude mcp add --transport http catalog-qa https://catalogqa.openkrill.app/mcpThat writes a local or user config. A JSON entry needs "type": "http" (or streamable-http) plus the url. An entry with a url and no type is skipped. Confirm with claude mcp get catalog-qa. The tools you should see are csv_import_preflight, merchant_feed_check, listing_text_audit, listing_fix_sheet.
Enable the connector only in conversations that need it. Claude can call the tools while you work, including during research, so turn off any tool you do not want invoked. Catalog QA Desk does not write to your accounts. It still receives the arguments of each call. Read the privacy page before you paste anything that is not public.
