What is the Acre Dados Abertos MCP Server?
Connect to the Acre Dados Abertos portal to query public information from the State of Acre. This server allows AI agents to browse, search, and analyze government datasets, organizational structures, and thematic groups.
What you can do
- Dataset Discovery — List and search for specific packages (datasets) like municipal GDP, environmental data, or demographic statistics.
- Metadata Inspection — Fetch detailed metadata for packages and individual resources (files) to understand data provenance and formats.
- Thematic Exploration — Browse data organized by thematic groups (e.g., economy, health, education) or by the specific government organizations that publish them.
- Deep Data Querying — Search and filter records directly within tabular resources (Datastore) like CSV files without downloading the entire dataset.
How it works
- Subscribe to this server
- (Optional) Enter your Acre API Key if you have one for higher rate limits
- Start querying public data from Claude, Cursor, or any MCP-compatible client
Who is this for?
- Data Analysts — quickly find and sample public datasets for research and reporting
- Journalists — verify government figures and find public records through natural language
- Developers — integrate real-time public data into applications using the Datastore search capabilities

Frequently asked questions
How can I search for datasets related to a specific topic like 'health'?
Use the search_packages tool with the query 'saude'. The agent will return a list of datasets matching that theme from the Acre portal.
Can I filter data inside a CSV file without downloading it?
Yes! If the resource is in the Datastore, use the search_datastore tool with the Resource ID. You can apply filters like {"municipio": "Rio Branco"} to get specific rows.
How do I find which government departments are publishing data?
Use the list_organizations tool to see all contributing entities, or list_groups to see thematic categorizations like 'Environment' or 'Economy'.
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.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
