## Tools (as reported by the server, not verified)

- `search\_datasets`: Search datasets by free text. IMPORTANT: check server instructions first — many common queries have a direct dataset\_id you can use with query\_dataset without searching. Only use search\_datasets when you don't know which dataset you need.
- `get\_dataset\_info`: Get complete metadata for a dataset: fields with types and descriptions, API endpoint, license, available formats and last update. Call after search\_datasets to get full details of a specific dataset.
- `list\_dataset\_fields`: List fields of a dataset with name, data type and description. Call before query\_dataset to know which fields and filters are available.
- `query\_dataset`: Query real data from a dataset. Check instructions for featured dataset\_ids and NOTES section for common filter patterns \(municipal budgets, contracts, weather, energy, fuel prices\).
- `list\_portals`: List all 13 indexed open data portals with dataset counts. Catalan portals \(Generalitat, Barcelona, Diba, AOC, Reus, Girona, FGC, Idescat, Renfe\) + Spanish national sources with Catalonia focus \(INE statistics, REE energy, SEPE employment, CNMC fuel prices\). No parameters required.
- `list\_categories`: List all dataset categories and themes with counts per portal. Great first step to discover what data types are available before searching with search\_datasets. Returns total datasets, count per portal and category list with counts. No parameters required.
- `related\_datasets`: Find related datasets from OTHER portals. Great for discovering complementary data: if you're looking at air quality from Generalitat, it may suggest traffic data from Barcelona or emissions from AOC. Relations are computed by thematic similarity across portals.
- `search\_radioteca`: Search radio shows, episodes and people indexed at radioteca.cat \(Catalan radio archive, \~485K documents from Catalunya Ràdio, RAC1, Catalunya Música, iCat, Catalunya Informació, RTVE, Cadena SER, ara.cat\). Searches across episode titles, descriptions \(which include a detailed summary of what was sa
