feed

scan

scan_product_feed

Fetch a public product feed once and score how well AI shopping assistants can understand it (0-100). Returns the biggest gaps (share of products affected), sample shopper questions AI could not answer from the feed, the thinnest products, and a link to fix the gaps. Accepts Google Merchant / Facebook catalog XML, CSV, TSV, or a Shopify store URL. Takes 20-60 seconds. Only summary results are stored.

shopping

list_ai_shopping_platforms

List the main AI shopping surfaces and how product data reaches each one (e.g. Google Merchant Center for Gemini / AI Mode / Shopping; ChatGPT merchant program). Overview only, not a list of live integrations.

AI Catalog by Crescendo Lab — questions

Answers built from our own checks of this server.

What can AI Catalog by Crescendo Lab do?

It exposes 3 tools, read directly from the server on our last check. Among them: get_feed_fix_guide, list_ai_shopping_platforms, scan_product_feed. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is AI Catalog by Crescendo Lab working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 1303 ms. The bar chart above shows every period we have measured.

How do I connect AI Catalog by Crescendo Lab?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does AI Catalog by Crescendo Lab need an API key?

No. AI Catalog by Crescendo Lab completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is AI Catalog by Crescendo Lab?

It answers our handshake in 1303 ms on average, which is faster than 2% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
