What is the Datos.gob.es (Catálogo Nacional) MCP Server?
Connect to the official Datos.gob.es API to explore Spain's vast repository of public sector information. This MCP server allows AI agents to query, filter, and analyze thousands of datasets from national, regional, and local administrations.
What you can do
- Dataset Discovery — Search for specific datasets by title or browse the entire catalog with advanced pagination and sorting.
- Advanced Filtering — Narrow down results by publisher ID, specific themes (e.g., health, economy), or file formats like CSV, JSON, and RDF.
- Geographic Analysis — Filter data by spatial scope, including provinces, regions, or specific administrative levels.
- Metadata Inspection — Retrieve detailed metadata for any dataset, including its distributions, update frequency, and issuing body.
- Public Sector Mapping — List and inspect public sector organizations, provinces, and regions involved in the open data ecosystem.
How it works
- Subscribe to this server
- The server connects to the public Datos.gob.es API

Frequently asked questions
How can I search for datasets containing a specific word in the title?
Use the search_datasets_by_title tool. Provide the string you are looking for in the title parameter, and the agent will return all matching datasets from the national catalog.
Is it possible to filter datasets by a specific file format like CSV or JSON?
Yes! Use the list_datasets_by_format tool and specify the format (e.g., 'csv', 'json', 'xlsx'). This will retrieve only the datasets that offer distributions in that format.
Can I find datasets belonging to a specific category like 'Health' or 'Environment'?
Absolutely. Use the list_datasets_by_theme tool with the corresponding theme ID. You can first use list_themes to see all available categories in the catalog.
How does LlamaIndex connect to MCP servers?
Use the MCP client adapter to create a connection. LlamaIndex discovers all tools and wraps them as query engine tools compatible with any LlamaIndex agent.
Can I combine MCP tools with vector stores?
Yes. LlamaIndex agents can query Datos.gob.es (Catálogo Nacional) tools and vector store indexes in the same turn, combining real-time and embedded data for grounded responses.
Does LlamaIndex support async MCP calls?
Yes. LlamaIndex's async agent framework supports concurrent MCP tool calls for high-throughput data processing pipelines.
