This server connects Claude to 2,991 public datasets across 14 Catalan and Spanish government portals. It exposes seven tools including search_datasets for full-text catalog search, query_dataset for live data queries with filters and pagination, and get_dataset_info for metadata inspection. You can pull real-time train positions via GTFS-RT from FGC and Renfe, query reservoir levels from Generalitat's Socrata API, check fuel prices by municipality from CNMC, or grab electricity pricing from REE. Built by opendata.cat, a nonprofit promoting open data transparency in Catalonia since 2012. The catalog auto-updates weekly and queries hit source APIs directly rather than proxying data. Reach for this when you need programmatic access to Catalan budgets, demographics, transport, environmental data, or CORA research outputs without manually wrangling thirteen different API formats.
