Inspect two exact creative lookups

We ran two separate US requests through the public MCP server, with a limit of one result per request. Both returned one Shopify record with the requested ID. Only one returned primary text.

Recorded Shopify lookups on November 10, 2026 UTC. Each source link opens the corresponding Meta Ad Library record.

Landing URL	Not returned	Not returned

Download the two-record JSON sample

The download preserves the requested and returned IDs and the field checks. A field marked “Not returned” was absent from that response. Open the source before quoting copy or claiming a destination.

Start with the right identifier

A library ID identifies a creative. A Page ID identifies an advertiser. If you only know the advertiser name, use facebook_ad_search to find candidates, confirm the advertiser, then select one creative to verify. The search can also return other advertisers, so check the Page ID before selecting a creative.

Connect MCP Scraper to your AI client using https://mcpscraper.dev/mcp. Check that facebook_page_intel appears in your client’s tool list before running the lookup.
Open the public Meta Ad Library detail link. Pass its library ID as a string, set the country, and start with maxAds: 1.
Compare the returned ads[0].libraryId with the request. Keep the source URL and mark any missing fields before using the record.

{
  "libraryId": "1751396829421229",
  "country": "US",
  "maxAds": 1
}

Compare this request with the recorded response before you run a lookup.
