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.

Why VS Code Copilot?
GitHub Copilot Agent mode brings Maranhão Open Data data directly into your VS Code workflow. With a project-scoped config, the entire team shares access to 6 tools. Copilot queries live data, generates typed code, and writes tests from actual API responses, all without leaving the editor.
- —
VS Code is used by over 70% of developers. adding MCP tools to Copilot means your team can leverage external data without leaving their primary editor
- —
Project-scoped MCP configs (
.vscode/mcp.json) let you commit server configurations to your repository, ensuring the entire team shares the same tool access - —
Copilot's Agent mode integrates MCP tools seamlessly with file editing, terminal commands, and workspace search in a single agentic loop
- —
GitHub's enterprise compliance and audit features extend to MCP tool usage, providing visibility into how AI interacts with external services

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.
Which VS Code version supports MCP?
MCP support requires VS Code 1.99 or later with the GitHub Copilot extension. Ensure both are updated to the latest version. Older versions of Copilot may not expose the Agent mode toggle.
How do I switch to Agent mode?
Open the Copilot Chat panel and look for two mode options: "Ask" and "Agent". Click "Agent" to enable autonomous tool calling. In Ask mode, Copilot provides conversational answers but cannot invoke MCP tools.
Can I restrict which MCP tools Copilot can access?
Yes. VS Code shows a tool consent dialog before any MCP tool is invoked for the first time. You can also configure tool access policies at the organization level through GitHub Copilot settings.
Does MCP work in VS Code Remote or Codespaces?
Yes. MCP servers configured via .vscode/mcp.json work in Remote SSH, WSL, and GitHub Codespaces environments. The MCP connection is established from the remote host, so ensure the server URL is accessible from that environment.
MCP tools not available
Ensure you are in Agent mode in Copilot Chat. MCP tools only appear in Agent mode.
