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.
Built-in capabilities (6)
Retrieve dataset metadata
g., a CSV file or API endpoint within a dataset). Retrieve resource metadata
List all datasets (packages) on the portal
Search within a resource in the DataStore

How Vinkius secures
Maranhão Open Data for OpenAI Agents SDK
Every tool call from OpenAI Agents SDK to the Maranhão Open Data MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
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 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.
