Chain environmental data with LangChain

Connect your LangChain agents to the IBAMA portal to automate complex research. You can pipe the output of `list_datasets` directly into a processing node to identify relevant environmental records without manual intervention. This setup allows you to create recursive reasoning loops. By passing the results of `search_datasets` into subsequent logic, your agent builds a complete picture of environmental metrics through autonomous tool execution.

Query tabular data with LangChain

Access raw environmental metrics by using `datastore_search` within your chains. Your LangChain agent can filter specific infraction records and format them for immediate reporting. It handles the data retrieval, so your code stays focused on the logic. You get clean, structured output ready for your next processing step.

Trace IBAMA Dados Abertos calls

Monitor every request sent to the IBAMA portal with LangSmith. You see exactly how `show_dataset` or `show_resource` performs within your agent pipeline. Debugging becomes a matter of checking the trace logs. You know if a tool call failed or if the data payload was empty before it hits your downstream functions.

Setup guide

Set up IBAMA Dados Abertos MCP in LangChain

Prerequisites

Python 3.10+ installed
langchain-mcp-adapters + langgraph packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run pip install langchain-mcp-adapters langgraph langchain-openai. The MCP adapters package converts MCP tools into native LangChain BaseTool objects.
2

Connect via HTTP transport
Use MultiServerMCPClient with "transport": "http" pointing to your Vinkius endpoint. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Create a ReAct agent
Pass the discovered tools to create_react_agent() from LangGraph. The agent automatically routes IBAMA Dados Abertos tool calls through the MCP protocol.
4

Run with any LLM
Swap ChatOpenAI for ChatAnthropic, ChatGoogleGenerativeAI, or any LangChain-compatible model. The MCP tools work identically across all providers.

agent.py

from langchain_mcp_adapters.client import MultiServerMCPClient
from langgraph.prebuilt import create_react_agent
from langchain_openai import ChatOpenAI

async with MultiServerMCPClient({
    "ibama-dados-abertos-mcp": {
        "transport": "http",
        "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp",
    }
}) as client:
    tools = client.get_tools()

    agent = create_react_agent(
        ChatOpenAI(model="gpt-4o"),
        tools,
    )
    result = await agent.ainvoke({
        "messages": "List recent IBAMA Dados Abertos transactions"
    })
    print(result["messages"][-1].content)

Common questions about IBAMA Dados Abertos MCP in LangChain

You install the MCP adapters and point the client at the server URL. Then, you call the tool loader to pass the IBAMA functions into your agent configuration.

Yes, you build a chain where the output of one tool call informs the next. This lets the agent decide which datasets to search and when to pull resource details.

The server manages the connection, but your chain logic controls the frequency. You should implement custom retries within your LangGraph workflow if you hit API limits.

Data exists only in the memory of your current session. The server provides access to live environmental records, but nothing is cached on disk by the MCP client.

Your queries stay between your local agent and the IBAMA servers. The MCP protocol transmits requests directly without storing your specific search parameters on any intermediate Vinkius infrastructure.
