What you can do

Dataset Discovery — List all available packages or search for specific topics like education, health, or finance using list_packages and search_packages.
Metadata Inspection — Retrieve detailed metadata for datasets and specific resources (CSV, PDF, API endpoints) with get_package and get_resource.
Data Exploration — Search within specific resource rows using search_datastore or execute complex SQL queries against the DataStore for deep analysis with search_datastore_sql.

FAQ

Frequently asked questions

How do I find datasets about a specific topic like 'education'?

You can use the search_packages tool with a query string. For example, searching for 'educação' will return all related datasets available on the portal.

Can I query the actual content of a CSV file without downloading it?

Yes! If the resource is in the DataStore, use search_datastore with the Resource ID to search through the rows directly.

Is it possible to perform complex filtering using SQL?

Absolutely. Use the search_datastore_sql tool to execute standard SQL queries against any resource stored in the portal's DataStore.

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.
