What is the Dades Obertes Catalunya MCP Server?
Unlock the power of Dades Obertes Catalunya, the official open data platform of the Government of Catalonia. This MCP server allows your AI agent to browse thousands of public datasets and perform complex queries through natural conversation.
What you can do
- Catalog Discovery — Search for datasets by keywords, categories, or tags to find relevant public information using the
search_catalogtool. - Advanced Querying — Use SoQL (Socrata Query Language) via
query_datasetto filter, select specific columns, and sort data from any dataset using its 4x4 identifier. - Data Analysis — Group results and perform full-text searches across entire datasets to extract insights on health, transport, economy, and more.
- Pagination & Limits — Efficiently handle large datasets with built-in support for limits and offsets to browse records systematically.
How it works
- Subscribe to this server
- (Optional) Enter your Socrata App Token for higher rate limits
- Start querying Catalan public data from Claude, Cursor, or any MCP-compatible client
Who is this for?
- Data Analysts — quickly pull public statistics into your workflow without manual CSV downloads
- Researchers — find and cross-reference government data on demographics, environment, or urban planning
- Developers — test data queries and explore API structures directly through natural language
Built-in capabilities (2)
g., abcd-1234). Supports SoQL parameters like $select, $where, $limit. Query a specific dataset using SoQL parameters
Returns dataset identifiers needed for the query_dataset tool. Search the Dades Obertes Catalunya catalog for datasets

Frequently asked questions
How do I find the unique identifier for a specific dataset?
Use the search_catalog tool with a descriptive query. The response will include the 4x4 alphanumeric ID (e.g., 'abcd-1234') which you can then use with the query_dataset tool.
Can I filter data by specific values like a city or a date range?
Yes! When using query_dataset, use the $where parameter to apply SoQL filters. For example, $where: "poblacio > 5000" or $where: "comarca = 'Barcelonès'".
Is a Socrata App Token mandatory to use this server?
No, it is optional. However, providing a DADES_APP_TOKEN allows for higher rate limits and prevents throttling during intensive data exploration.
How does Mastra AI connect to MCP servers?
Create an MCPClient with the server URL and pass it to your agent. Mastra discovers all tools and makes them available with full TypeScript types.
Can Mastra agents use tools from multiple servers?
Yes. Pass multiple MCP clients to the agent constructor. Mastra merges all tool schemas and the agent can call any tool from any server.
Does Mastra support workflow orchestration?
Yes. Mastra has a built-in workflow engine that lets you chain MCP tool calls with branching logic, error handling, and parallel execution.
