MerchantStamp Catalog Audit is the AI-readiness layer for WooCommerce catalogs.
It helps merchants audit catalog quality, enrich missing product schema, and publish AI-ready feeds — without replacing their existing SEO or feed plugin.
Unlike traditional feed plugins focused on channel exports, this plugin focuses on catalog completeness and machine readability for modern AI-driven discovery.
<h4>Fully functional, free, and offline-first</h4>
This plugin is 100% functional locally. Every feature listed below runs on your server with no external service required. There is no time limit, no product cap, no locked feature behind a license key.
<ul>
<li>Full ShopScore audit (no product limit)</li>
<li>Field Coverage Analytics</li>
<li>Top Issues panel (the fields with the most missing values, ranked)</li>
<li>Prioritized Recommendations (actions ranked by estimated ShopScore gain)</li>
<li>JSON-LD enrichment on top of Yoast, Rank Math, or native WooCommerce</li>
<li><code>products.jsonld</code> feed (schema.org Product catalog)</li>
<li><code>llms.txt</code> feed (LLM-friendly catalog summary)</li>
<li><code>acp.json</code> feed (Agent Commerce Protocol)</li>
<li><code>agent.json</code> feed (with SHA-256 content-integrity proof)</li>
<li>Scan history archive (60 most recent scans)</li>
<li>Score Trend sparkline</li>
<li>Compare any two scans (delta score, delta critical missing, per-field coverage diff)</li>
<li>Degradation alerts (banner when ShopScore drops or critical-missing rises)</li>
<li>Automatic feed rebuild on product create / update / delete / stock change</li>
<li>WooCommerce admin dashboard</li>
<li>Full HPOS compatibility</li>
</ul>
<h4>Optional external service</h4>
The plugin can optionally connect to the MerchantStamp service for capabilities that genuinely require a centralized backend. The plugin works entirely without it.
What the service adds (Guideline 6 — Serviceware):
<ul>
<li>Centralized multi-site dashboard — manage catalog quality across multiple WooCommerce stores from one place</li>
<li>Cross-site verification key — published at <code>merchantstamp.com/.well-known/keys/<slug></code>, referenced inside <code>agent.json</code> so AI agents can verify the integrity of your published feed against a public key you control</li>
<li>Storefront discovery loader — a small JavaScript snippet (versioned, SRI-protected, opt-in) injected in the footer that helps AI agents find this site’s feeds at scale</li>
<li>Advanced alerting — Slack and email delivery of degradation alerts, beyond the in-admin banner that this plugin shows for free</li>
<li>Push notifications to your MerchantStamp dashboard after each rebuild</li>
</ul>
Pricing for the MerchantStamp service is at <a href="https://merchantstamp.com" rel="nofollow ugc">merchantstamp.com</a>.
<h4>Built to work alongside your stack</h4>
<ul>
<li>Yoast SEO / Yoast WooCommerce SEO</li>
<li>Rank Math / Rank Math PRO</li>
<li>AIOSEO</li>
<li>Google for WooCommerce</li>
<li>Product Feed PRO for WooCommerce</li>
<li>Any WooCommerce-compatible theme</li>
</ul>
If another plugin already outputs valid schema, this plugin does not overwrite it. It fills missing fields only.
<h4>Read-only by design</h4>
This plugin does not rewrite your WooCommerce product catalog. It reads your product data, computes scores, enriches structured output at render time, and generates feed files from existing catalog data.
<h4>External services</h4>
This plugin connects to MerchantStamp services only when the user enters an API key. Without an API key, no external connection is ever made.
When a user enters a MerchantStamp API key, the plugin connects to:
1. MerchantStamp Activation & Push API
<ul>
<li>Endpoint: <code>https://merchantstamp.com/api/webhooks/plugin</code></li>
<li>Purpose: Validate the API key on activation, and report feed-build status after each rebuild so the merchant’s MerchantStamp dashboard stays in sync.</li>
<li>Data sent: site URL, plugin version, WordPress version, WooCommerce version, the merchant’s chosen slug, public feed URLs, total product count, average ShopScore, build duration in milliseconds, and a UTC timestamp.</li>
<li>No personal data, customer data, or order data is ever sent.</li>
<li>Terms of service: https://merchantstamp.com/en/legal</li>
<li>Privacy policy: https://merchantstamp.com/en/privacy</li>
</ul>
2. Optional Storefront Loader Script
<ul>
<li>URL: <code>https://merchantstamp.com/js/silver-loader.v1.0.0.js</code></li>
<li>Purpose: A small JavaScript file injected in the site footer (only when an API key is entered AND the filter <code>msca_inject_loader</code> is true) that helps AI discovery systems find this site’s published feeds.</li>
<li>Source code: https://github.com/arnaud-92/silver-loader</li>
<li>Subresource Integrity: loaded with an SRI hash so the browser refuses to execute any modified copy.</li>
<li>
Opt-out: site owners can disable the loader injection at any time by adding the following filter:
add_filter( ‘msca_inject_loader’, ‘__return_false’ );
</li>
</ul>
<h4>Privacy</h4>
<ul>
<li>Without an API key entered, this plugin sends no data to any external service.</li>
<li>With an API key, the plugin sends only operational metadata listed in the External services section above.</li>
<li>No customer data, order data, email addresses, IP addresses, or other personal information is collected, stored, or transmitted by this plugin.</li>
<li>All generated feed files contain only public product information already published on the merchant’s WooCommerce store.</li>
<li>Plugin settings are stored in the standard WordPress options table; no custom database tables are created.</li>
<li>Scan history and cache are stored under <code>wp-content/uploads/merchantstamp-catalog-audit/private/</code> (created with index.php silencers and <code>.htaccess</code> denial rules).</li>
</ul>
