Who it is for
Marketplace sellers and catalogue teams running a completeness check before listings reach review or go live.
Check product listings for missing required fields
Overview
Product Listing Validator inspects product listing data and reports whether the fields needed before review or publication are present. The result comes back structured: which fields were found, which are absent, and any validation errors in what was supplied.
The examples in the record check a listing for title, description, price, and images, or ask for the gaps in a listing to be identified with nothing else altered. Checking and reporting is the whole function. Publishing and editing sit outside it, which places the app at a review step before a listing goes out rather than in the publishing path itself. Beike Yan is the developer.

It reports on listing data without touching or publishing it, keeping validation separate from any write action.
Availability
Product Listing Validator is listed in the ChatGPT apps directory only. BEIKE YAN has no connector under the same domain in the Claude directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.
ChatGPT apps are built on MCP, and the same server can back a Claude connector, so the absence is a distribution decision rather than a technical one.

This is an independent catalogue entry compiled by Node8 from Product Listing Validator's public marketplace listing as it stood in August 2026. Listing facts come from the marketplaces; the comparisons against the rest of the directory and any live-endpoint measurements are Node8's. Node8 is not affiliated with BEIKE YAN, and inclusion here is not an endorsement.
Node8 builds MCP servers end to end: deciding which tools are worth exposing, the authentication and permission model, the review submissions, and the onboarding that gets them used. One server serves ChatGPT, Claude, and Microsoft Copilot.
