Perplexity

Delegate taxonomy research to specialized agents

The `list_secoes_cnae` tool allows your researcher agent to map broad economic sectors across Brazil's complex regulatory landscape. Instead of one bot doing everything, a dedicated analyst agent focuses solely on identifying high-level industry trends. Once the researcher agent collects the broad sectors, it passes the data to an auditor agent. This second agent uses `list_divisoes_cnae` to drill down into the specific divisions, keeping the entire process organized and efficient.

Automate corporate tax classification audits

The `get_subclasse_cnae` tool retrieves specific tax and compliance parameters for any given business activity. Your compliance agent uses this tool to cross-reference a company's self-reported activities against official IBGE definitions. If a discrepancy is found, the agent escalates the issue to a supervisor agent. This multi-tiered approach ensures that tax classification errors are caught and corrected before they cause legal issues.

Coordinate multi-agent lookups with CrewAI

The `list_subclasses_por_classe` tool exposes the granular codes needed for precise market segmentation. By connecting this MCP Server to CrewAI, your marketing agent can identify emerging business trends within highly specific niches. The framework handles the passing of context between agents automatically. Your research crew can use `list_classes_cnae` to build a list of target industries and then immediately run deep-dives on each subclass without manual coding.

Setup guide

Set up IBGE Economia — CNAE Activities MCP in CrewAI

Prerequisites

Python 3.10+ installed
crewai package (pip install crewai)
Active Vinkius subscription with a valid endpoint token

1

Install CrewAI
Run pip install crewai to install the framework. MCP support is built-in via the mcps parameter.
2

Add the MCP URL to your agent
Pass your Vinkius endpoint directly to the mcps list. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. CrewAI handles tool discovery and caching automatically.
3

Kick off your crew
Create a Crew with your agent and tasks. Call crew.kickoff() — the agent will automatically invoke IBGE Economia — CNAE Activities tools as needed.

crew.py

from crewai import Agent, Task, Crew

agent = Agent(
    role="IBGE Economia — CNAE Activities Analyst",
    goal="Access and analyze IBGE Economia — CNAE Activities data via MCP.",
    backstory="Expert analyst with direct IBGE Economia — CNAE Activities access.",
    mcps=[
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    ],
)

task = Task(
    description="List recent IBGE Economia — CNAE Activities transactions",
    agent=agent,
    expected_output="A summary of recent activity",
)

crew = Crew(agents=[agent], tasks=[task])
result = crew.kickoff()
print(result)

Prerequisites

Python 3.10+ installed
crewai + crewai-tools packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run pip install crewai crewai-tools. The MCPServerAdapter handles lifecycle management and tool conversion.
2

Connect with MCPServerAdapter
Use MCPServerAdapter as a context manager with SseServerParameters pointing to your Vinkius endpoint. The adapter automatically manages connection lifecycle.
3

Assign tools and run
Pass the returned mcp_tools to your agent's tools parameter. The adapter converts MCP tools to native BaseTool objects compatible with all CrewAI agents.

crew.py

from crewai import Agent, Task, Crew
from crewai_tools import MCPServerAdapter
from mcp import SseServerParameters

server_params = SseServerParameters(
    url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
)

with MCPServerAdapter(server_params) as mcp_tools:
    agent = Agent(
        role="IBGE Economia — CNAE Activities Analyst",
        goal="Access and analyze IBGE Economia — CNAE Activities data via MCP.",
        backstory="Expert analyst with direct IBGE Economia — CNAE Activities access.",
        tools=mcp_tools,
    )

    task = Task(
        description="List recent IBGE Economia — CNAE Activities transactions",
        agent=agent,
        expected_output="A summary of recent activity",
    )

    crew = Crew(agents=[agent], tasks=[task])
    result = crew.kickoff()

Common questions about IBGE Economia — CNAE Activities MCP in CrewAI

Pass the Vinkius HTTP endpoint into the agent's mcps list. This limits MCP tool access, ensuring only your compliance agent can call get_subclasse_cnae while keeping other agents lightweight.

Yes. One agent can retrieve the high-level sections using list_secoes_cnae, write the results to shared memory, and another agent can pick up those codes to run list_divisoes_cnae queries.

Set strict iteration limits on your CrewAI agents. This prevents them from repeatedly calling list_subclasses_por_classe when searching through large, complex economic categories.

The integration supports both standard stdio for local execution and SSE for remote, cloud-hosted agents, giving you flexibility in how you deploy your compliance crew.

No. The MCP server only processes public IBGE codes and descriptions. Your clients' private tax categories and proprietary business classifications remain entirely within your secure local environment.
