The Cracks Index
Connects Claude to The Cracks Index, a reproducible ranking of 40 countries by social safety net strength. You get read-only access to composite scores (0-100, lower is better), six weighted public indicators covering homelessness to poverty rates, country comparisons, and municipal-level data for the Netherlands. The underlying data is fully open under CC-BY-4.0 with transparent methodology. Reach for this when you need citeable cross-country welfare statistics, want to compare social outcomes across OECD nations, or need to pull structured policy data without touching any personal information. All calculations are reproducible from public aggregates.
