OpenSwissData

cammac-creator/openswissdata

Pulls normalized Swiss federal datasets into Claude: TARES customs tariff codes, FINMA's financial institution registry, and NOGA economic activity classifications. You get nine tools that query production APIs hosted at mcp.openswissdata.com. Reach for this when you're building compliance workflows, need to validate Swiss business registrations, or are working with import/export documentation that references official tariff nomenclature. The maintainer runs ETL pipelines to keep each dataset synced with government sources and versions the releases. Built for data engineers who'd rather query clean APIs than scrape PDF tables from admin.ch.
