What is the Aragón Open Data MCP Server?

Connect to the Aragón Open Data portal and unlock a wealth of public information from the Government of Aragón. This MCP server allows your AI agent to browse, search, and analyze regional datasets, statistical views, and organizational metadata through natural language.

What you can do

Data Exploration — List all available views and datasets from the GA_OD_Core and CKAN catalogs.
Deep Data Preview — Fetch and preview actual records from specific views or resources with support for filtering and pagination.
Schema Inspection — Understand the structure of data by retrieving column names and data types for any specific view.
Advanced Search — Use Solr-powered queries to find specific datasets, tags, or organizations within the public catalog.
Publisher Insights — Retrieve detailed information about the organizations and themes (groups) that publish data in the region.

How it works

Subscribe to this server
Enter your Aragón Open Data API Key (optional for public endpoints)
Start querying public records from Claude, Cursor, or any MCP-compatible client

Who is this for?

Data Analysts — quickly find and preview regional statistics without manual CSV downloads
Developers — inspect API schemas and data structures directly from the code editor
Researchers & Journalists — search for public records and government transparency data through conversation

FAQ

Frequently asked questions

Can I filter the data preview to see only specific records?

Yes! Use the preview_data tool and provide a JSON string in the filters parameter (e.g., {"entidad": "ARANDA"}). This allows you to restrict the results to exactly what you need.

How do I find the structure and data types of a specific view?

You can use the show_columns tool by providing the view_id. It will return a detailed list of all columns, their descriptions, and their technical data types.

Is it possible to search for datasets by keywords or topics?

Absolutely. Use the search_datasets tool with the q parameter to perform a Solr search across the entire CKAN catalog for relevant datasets.

How does LangChain connect to MCP servers?

Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.

Which LangChain agent types work with MCP?

All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
