Compatible with every major AI agent and IDE
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

Why teams choose Vinkius for Aragón Open Data in OpenAI Agents SDK
The Aragón Open Data MCP Server runs on Vinkius-managed infrastructure inside AWS — a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts. All 15 tools execute in hardened sandboxes optimized for native MCP execution.
Your AI agents in OpenAI Agents SDK only access the data you authorize, with DLP that blocks sensitive information from ever reaching the model, kill switch for instant shutdown, and up to 60% token savings. Enterprise-grade infrastructure, zero maintenance.

* Every MCP server runs on Vinkius-managed infrastructure inside AWS - a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts optimized for native MCP execution. See our infrastructure
How Vinkius secures
Aragón Open Data for OpenAI Agents SDK
Every tool call from OpenAI Agents SDK to the Aragón Open Data MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
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 the OpenAI Agents SDK connect to MCP?
Use MCPServerSse(url=...) to create a server connection. The SDK auto-discovers all tools and makes them available to your agent with full type information.
Can I use multiple MCP servers in one agent?
Yes. Pass a list of MCPServerSse instances to the agent constructor. The agent can use tools from all connected servers within a single run.
Does the SDK support streaming responses?
Yes. The SDK supports SSE and Streamable HTTP transports, both of which work natively with Vinkius.
