- Package: Npm @opendata.cat/mcp-server v0.3.6
- Remote endpoint: https://opendata.cat/api/mcp

## Tools
- 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. Endpoint: https://opendata.cat/api/mcp
- 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. Endpoint: https://opendata.cat/api/mcp
- 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. Endpoint: https://opendata.cat/api/mcp
- 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). Endpoint: https://opendata.cat/api/mcp
- 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. Endpoint: https://opendata.cat/api/mcp
- 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. Endpoint: https://opendata.cat/api/mcp
- 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. Endpoint: https://opendata.cat/api/mcp
