How to Use the Correios (Brazil) MCP in CrewAI

Q: How do multiple agents share Correios (Brazil) tracking data in CrewAI?

Your tracking agent uses trackobject to fetch package statuses. CrewAI's shared memory system then makes this Correios (Brazil) data available to your customer support agent for immediate draft responses.

Q: Can a CrewAI agent validate Brazilian addresses using Correios (Brazil)?

Yes, you can assign lookupcep to a specialized data-entry agent. The agent takes raw user inputs, verifies them against the Correios (Brazil) database, and updates your CRM.

Q: How do I restrict which CrewAI agents can access Correios (Brazil) contract tools?

You use CrewAI's tool filter options to expose getcontractstatus only to your manager agent using MCP filters. Other agents in the crew will only see public tools like lookupcep or trackobject.

Perplexity

Coordinate multi-agent package tracking pipelines

The `track_object` tool monitors the physical location of Brazilian shipments. In a CrewAI setup, your tracking agent uses this tool to watch for transit delays and hand the data off to a customer-service agent. This division of labor prevents your main agent from getting bogged down in API calls. The tracking agent loops through your active tracking codes, updates the shared memory, and lets the rest of the crew act on the results.

Calculate regional shipping costs with agent teams

The `calculate_price_deadline` tool calculates exact shipping fees across different Brazilian states. Your financial agent calls this tool to compare rates, while a logistics agent matches those rates against delivery deadlines. By running these agents in a sequential crew, you automate the entire quote-to-dispatch pipeline. The crew evaluates the cost, verifies the destination CEP, and recommends the cheapest shipping method.

Audit corporate shipping contracts via CrewAI MCP Server

The `get_contract_status` tool retrieves active service agreements from your Correios corporate account. A dedicated auditor agent in your CrewAI team runs this tool to ensure your account remains active and has access to discount tiers. This MCP Server exposes clean endpoints that your agents can call without needing custom Python wrappers. The crew reads your contract details directly, matching them against active shipments to flag billing discrepancies.

Setup guide

Set up Correios (Brazil) 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 Correios (Brazil) tools as needed.

crew.py

from crewai import Agent, Task, Crew

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

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

    task = Task(
        description="List recent Correios (Brazil) transactions",
        agent=agent,
        expected_output="A summary of recent activity",
    )

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