More Details Connect to Claude

The European Open Data Portal (data.europa.eu) as a single MCP server — the official EU portal aggregating open data from all member states and neighbouring countries.

What you can do

  • Full-text search across 1.9M+ datasets — titles, descriptions, publishers, keywords, with pagination
  • Country-focused search — slice any query by one of 36 country codes (national portals are all harvested)
  • Format-aware search — keep only datasets with CSV/JSON/GeoJSON/XML distributions, so agents get data they can actually parse
  • High-Value Datasets (HVD) — find the datasets EU regulation 2023/138 obliges member states to publish free, machine-readable and via APIs: geospatial, earth observation, meteorological, statistics, company registries and mobility
  • Full dataset details — every distribution with direct download URLs, licences, contact points, temporal/spatial coverage and data.europa.eu quality scores
  • Catalogue browser — see the national and thematic sources behind every dataset

Why data.europa.eu

This is the single entry point to Europe's public data infrastructure: national portals (dados.gov.pt, data.gouv.fr, govdata.de...), EU institutions (Eurostat, EEA, ECA) and the mandated High-Value Datasets. An agent that can search it can ground market research, journalism, policy analysis and product development in official public data — no API key, no registration.

Typical workflows

  • Market research: company registries and statistics per country (HVD category)
  • Environment/energy analysis: air quality, earth observation and meteorological HVDs
  • Mobility apps: GTFS transport feeds and geospatial HVDs
  • Due diligence: verify publishers and licences before reuse

8 tools expose this connector's capabilities to your AI agent.

get_dataset_details

Unlike the search rows, this returns every distribution (file) with accessUrl/downloadUrl, format and licence, plus contact points, temporal/spatial coverage and data.europa.eu quality scores (accessible/known licences etc.). Use it as the step right before actually downloading a dataset. Full details for one dataset: all distributions with direct download URLs, formats, licence, contacts and quality measurements

find_high_value_datasets

High-Value Datasets are the six categories the EU considers most valuable for reuse: geospatial, earth observation & environment, meteorological, statistics, companies & company ownership, and mobility — each with special licensing obligations (free, machine-readable, APIs). Use when you want the EU's curated best data for market research, apps or products. Query is MANDATORY. Find EU "High-Value Datasets" (HVD) — the datasets the EU mandates member states to provide for free and via APIs

find_hvd_in_country

Great for "what is Portugal legally required to open up?" style questions. Query is MANDATORY. High-Value Datasets from one specific European country (e.g. "pt" Portugal, "de" Germany) — curated, API-accessible data

search_datasets_by_country

Use for country-specific questions: national statistics, government spending, environment, transport. Note the portal aggregates national portals, so coverage mirrors what each country publishes. Query is MANDATORY. Search all open datasets — not only HVDs — from one specific European country

search_datasets_by_format

g. "csv", "json", "geojson", "xml", "parquet", "shp"). Ideal when an agent needs data it can parse directly instead of PDFs. Query is MANDATORY. Search datasets and see/download only machine-readable formats (CSV, JSON, XML, GeoJSON...)

list_catalogues

europa.eu — typically one per country's national open data portal plus thematic sources (EEA, Eurostat, EDP...). Useful for understanding data provenance: a dataset's "catalogue" field links back to one of these. Pass a keyword to try filtering by name substring. Browse the national and thematic catalogues harvested by the portal (one catalogue per source: national portals, EEA, Eurostat...)

get_portal_reference

Read it before country/HVD workflows if unsure. Reference: what data.europa.eu is, HVD categories, EU country codes and usage tips for the other tools

search_datasets

europa.eu, official EU portal aggregating national portals). Each row has: id, title, trimmed description, country, publisher, categories, keywords, dates and the landing page URL. Query is MANDATORY. Combine topic + geography keywords, e.g. "air quality berlin", "tourism statistics portugal", "public transport gtfs". Too many hits? Narrow with search_datasets_by_country or add more specific keywords. Take dataset ids into get_dataset_details for download links. Search 1.9M+ open datasets from 36 European countries in the official data.europa.eu portal — titles, publishers, countries, keywords and download landing pages

Find open data about air quality in Portugal that I can download as CSV

📊 **Air quality data in Portugal (CSV)** From data.europa.eu: 1. **QualAr — Air Quality Index** (APA, PT) — daily per-station index, CSV distributions 2. **EEA AirBase** — harmonised European measurements incl. PT stations, CSV/JSON Take the dataset ids and I'll pull get_dataset_details for the direct download URLs, licences and update frequency.

Which High-Value Datasets must Germany provide? I need company registry data for market research

🏛️ **Germany's High-Value Datasets — companies category** Under Regulation 2023/138, company registries are a mandatory HVD category. From data.europa.eu (filtered: country=de, HVD): - **Unternehmensregister** — official German company register distributions - **North Data** sample datasets — structured company ownership data These are free and machine-readable by law. I can pull full details (download URLs, licences) for whichever you pick.

No key needed — the portal's search API is fully public. Reuse conditions belong to each dataset: most open data is CC-BY or similar, but licences vary per source, so always check the licence field in get_dataset_details before republishing. High-Value Datasets are guaranteed free and machine-readable by EU regulation.
