Compatible with every major AI agent and IDE
What is the Maranhão Open Data MCP Server?
Connect to the Maranhão Open Data Portal to explore government transparency data directly through your AI agent. This server interfaces with the state's CKAN-based infrastructure to provide real-time access to public information.
What you can do
- Dataset Discovery — List all available packages or search for specific topics like education, health, or finance using
list_packagesandsearch_packages. - Metadata Inspection — Retrieve detailed metadata for datasets and specific resources (CSV, PDF, API endpoints) with
get_packageandget_resource. - Data Exploration — Search within specific resource rows using
search_datastoreor execute complex SQL queries against the DataStore for deep analysis withsearch_datastore_sql.
How it works
- Subscribe to this server
- (Optional) Enter your Maranhão API Key for higher rate limits
- Start querying public data from Claude, Cursor, or any MCP-compatible client
Who is this for?
- Researchers & Journalists — quickly find and analyze government spending, social indicators, and public contracts.
- Developers — integrate public data into applications without manually browsing the portal.
- Data Analysts — run SQL queries directly on government datasets to generate insights and reports.

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 do I add an MCP server to Claude Code?
Run claude mcp add <name> --transport http "<url>" in your terminal. Claude Code registers the server and discovers all tools immediately.
Can Claude Code run MCP tools in headless mode?
Yes. Claude Code supports non-interactive execution, making it ideal for scripts, cron jobs, and CI/CD pipelines that need MCP tool access.
How do I list all connected MCP servers?
Run claude mcp in your terminal to see all registered servers and their status, or type /mcp inside an active Claude Code session.
