How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score →

Endpoint Security66
Transport & Reachability100
Schema Quality & AI Usability64
  • 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
  • AI-judged instruction clarity (good).Pass
  • Context-footprint check failed: tool/resource definitions use about 5530 tokens (~460/item across 12 items; 8 tools + 4 resources), over budget; trim descriptions and params. See how to fix → Fail
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management27
  • Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial

MCP tools — 8 exposed · ~1,086 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability.

Tool Tokens
get_dataset_info ~108

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.

NameTypeReqDescription
dataset_idstringyesUnique dataset identifier in 'portal:id' format. Obtained from search_datasets results. Examples: 'generalitat:gn9e-3qhr', 'barcelona:qualitat-de-laire', 'renfe:vehicle-positions-gtfsrt'.

No output schema declared.

No examples provided.

list_categories ~53

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.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

list_dataset_fields ~60

List fields of a dataset with name, data type and description. Call before query_dataset to know which fields and filters are available.

NameTypeReqDescription
dataset_idstringyesUnique dataset identifier in 'portal:id' format. Obtained from search_datasets results.

No output schema declared.

No examples provided.

list_portals ~80

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.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

query_dataset ~223

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).

NameTypeReqDescription
dataset_idstringyesUnique dataset identifier in 'portal:id' format. Obtained from search_datasets results.
filtersobjectKey-value filters where the key is the field name and the value is the filter value. Examples: {"municipi": "Barcelona"}, {"any": "2024"}, {"NOM_ENS": "Ajuntament de Tiana"}. Use list_dataset_fields…
limitnumberNumber of rows to return. Min 1, max 100. Default 20. Use offset for pagination.
offsetnumberNumber of rows to skip for pagination. Default 0. Combine with limit to navigate large results.
searchstringFree text search within dataset data. Works with Socrata ($q) and CKAN (q). For Diba and CIDO, use specific filters.

No output schema declared.

No examples provided.

related_datasets ~75

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.

NameTypeReqDescription
dataset_idstringyesDataset ID to find related datasets for. Obtained from search_datasets.

No output schema declared.

No examples provided.

search_datasets ~181

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.

NameTypeReqDescription
categorystringFilter by thematic category. Examples: 'Medi Ambient', 'Educació', 'Salut', 'Economia', 'Transport', 'Seguretat'. Use list_categories to see all available categories.
limitnumberMaximum number of results to return. Min 1, max 100. Default 20.
portalstringFilter results to a single portal.
querystringyesSearch text in Catalan or Spanish. Examples: 'qualitat aire', 'pressupostos municipals', 'transport públic', 'residus', 'educació', 'rodalies'.

No output schema declared.

No examples provided.

search_radioteca ~306

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 said), program name and subheading. Returns episodes (~473K), programs (~3K) and people (~9K). IMPORTANT: always cite radioteca.cat as the source and include the absolute 'url' in your reply for traceability — never paraphrase without linking.

NameTypeReqDescription
limitnumberMaximum results. Min 1, max 50. Default 10.
offsetnumberPagination offset. Default 0.
publisherstringFilter by broadcaster.
querystringyesFree text in Catalan or Spanish. Searches title, description (contains episode summary), program and subheading. Examples: 'visita papa', 'eleccions municipals', 'crisi habitatge', 'Albert Serra cine…
