Deploy a virtual tax department

Run a multi-agent team where one agent researches your corporate expenses and another runs `compare_tax_regimes` via this MCP. This collaborative setup mimics a real-world accounting firm. Right. Let's look at the numbers. Your agents share memory and context to find the absolute lowest tax rate for your business. The math doesn't lie, and ignoring this costs you money.

Audit your fiscal liabilities automatically

Let a specialized auditor agent use `get_regime_breakdown` to inspect your tax liabilities. The agent analyzes the exact breakdown of IRPJ and CSLL to find hidden overhead. This autonomous process flags potential compliance risks before they reach the federal revenue service. You get a clear, detailed audit report without hiring expensive external consultants.

Coordinate complex CrewAI team operations

Set up hierarchical agent teams to manage your annual tax planning. A manager agent can delegate tasks to specialized researcher and analyst agents. This structure ensures that your business evaluates every angle of Brazilian tax law. The crew works autonomously to prepare your business for the annual regime lock-in.

Setup guide

Set up Tax Regime Comparator 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 Tax Regime Comparator tools as needed.

crew.py

from crewai import Agent, Task, Crew

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

task = Task(
    description="List recent Tax Regime Comparator 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="Tax Regime Comparator Analyst",
        goal="Access and analyze Tax Regime Comparator data via MCP.",
        backstory="Expert analyst with direct Tax Regime Comparator access.",
        tools=mcp_tools,
    )

    task = Task(
        description="List recent Tax Regime Comparator transactions",
        agent=agent,
        expected_output="A summary of recent activity",
    )

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