15 Catalan portals + radio archive: gov, INE/REE/CNMC, CORA, Catalònica, radioteca.cat.
Connects an assistant to Catalan open data: search 3,000+ datasets across 15 portals, inspect metadata, and query real data plus a radio archive.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/io.github.xaviviro%2Fopendata-cat/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Add this to your client's mcpServers config.

Servidor MCP (Model Context Protocol) que connecta els models de llenguatge (Claude, ChatGPT, Gemini...) amb les dades obertes publiques de Catalunya. Cerca datasets, explora metadades i consulta dades reals de 15 portals directament des del teu assistent d'IA.
Un projecte d'opendata.cat — associacio sense anim de lucre fundada el 2012 que promou la transparencia, la difusio i l'estandarditzacio de les dades obertes a Catalunya. Inspirat en el projecte datagouv-mcp del govern frances.
+3.073 datasets de 15 portals. La majoria queryables amb filtres, cerca i paginacio.
El cataleg s'actualitza automaticament cada setmana. Crawling incremental amb --portal per carregar fonts noves sense re-escanejar tot.
Tipus d'acces:
Afegeix al fitxer de configuracio (~/Library/Application Support/Claude/claude_desktop_config.json a macOS o %APPDATA%\Claude\claude_desktop_config.json a Windows):
Afegeix al fitxer .vscode/mcp.json del teu projecte:
Consulta la guia completa amb instruccions per a 13 clients MCP a opendata.cat/mcp.
Tambe pots connectar directament via Streamable HTTP sense instal·lar res:
Cerca datasets per text lliure.
Executa una consulta directament contra el portal origen i retorna dades reals.
Exemples de filtres per fonts estatals:
ree:preus-electricitat — preus PVPC per horafilters: {"municipi": "Sabadell"} — gasolineres de SabadellA més de les tools i els prompts, el servidor publica skills: guies d'investigació
(estil SKILL.md) que orienten l'LLM pas a pas en un domini concret — com triar el dataset,
filtrar, paginar i citar bé. Es distribueixen dins el paquet (skills/) i es serveixen com a
resources MCP (skill://<nom>/SKILL.md, via resources/list + resources/read) i com a
prompts-pont invocables com a slash-command (/mcp__opendata_cat__skill_<nom>).
Les mateixes skills es serveixen també des de l'endpoint HTTP https://opendata.cat/api/mcp.
Un cop configurat, pots fer preguntes al teu LLM com:
No emmagatzema ni fa de proxy de dades. Cada consulta va directament a la font oficial.
A mes del servidor MCP, opendata.cat ofereix una API REST publica:

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.
limitqueryrequiredportalcategoryGet 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.
dataset_idrequiredList fields of a dataset with name, data type and description. Call before query_dataset to know which fields and filters are available.
dataset_idrequiredQuery 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).
limitoffsetsearchfiltersdataset_idrequiredList 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.
Takes no parameters.
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.
Takes no parameters.
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.
dataset_idrequiredSearch 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.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
Declare a license in the repository or the registry entry.
