What is the Correios (Brazil) MCP Server?
Connect your AI agents to Correios, the official national postal service of Brazil. This MCP provides 9 tools to automate real-time object tracking, calculate shipping deadlines and prices (PAC, SEDEX), and retrieve accurate address information using Brazilian zip codes (CEP) directly through natural conversation.
What you can do
- Logistics Orchestration — Track multiple packages and retrieve granular status updates and historical events
- Shipping Intelligence — Calculate delivery deadlines and prices for various services between any two zip codes
- Address Validation — Retrieve complete street, neighborhood, and city details for any Brazilian CEP
- Business Integration — Access organizational contract configurations and list authorized service codes programmatically
- Regional Insights — Verify the state and city information associated with specific postal zones
How it works
- Subscribe to this server
- Log in to the Correios Web Services Portal
- Navigate to API Management to obtain your Username, Password, and Contract Number (if applicable)

Why CrewAI?
When paired with CrewAI, Correios (Brazil) becomes a first-class tool in your multi-agent workflows. Each agent in the crew can call Correios (Brazil) tools autonomously, one agent queries data, another analyzes results, a third compiles reports, all orchestrated through Vinkius with zero configuration overhead.
- —
Multi-agent collaboration lets you decompose complex workflows into specialized roles, one agent researches, another analyzes, a third generates reports, each with access to MCP tools
- —
CrewAI's native MCP integration requires zero adapter code: pass Vinkius Edge URL directly in the
mcpsparameter and agents auto-discover every available tool at runtime - —
Built-in task delegation and shared memory mean agents can pass context between steps without manual state management, enabling multi-hop reasoning across tool calls
- —
Sequential and hierarchical crew patterns map naturally to real-world workflows: enumerate subdomains → analyze DNS history → check WHOIS records → compile findings into actionable reports

Frequently asked questions
Can my AI automatically track a package just by providing the tracking code?
Yes! Use the track_object tool with the tracking code (e.g., 'QI123456789BR'). Your agent will retrieve the current status, location, and the full history of logistics events.
How do I calculate shipping prices for PAC or SEDEX?
Use the calculate_shipping tool with the origin and destination CEPs, along with the weight and dimensions of the package. The agent will return the estimated price and delivery deadline.
Can I retrieve the full address details from a zip code (CEP)?
Yes! The search_cep tool allows your agent to fetch the street name, neighborhood, city, and state associated with any valid Brazilian zip code.
How does CrewAI discover and connect to MCP tools?
CrewAI connects to MCP servers lazily. when the crew starts, each agent resolves its MCP URLs and fetches the tool catalog via the standard tools/list method. This means tools are always fresh and reflect the server's current capabilities. No tool schemas need to be hardcoded.
Can different agents in the same crew use different MCP servers?
Yes. Each agent has its own mcps list, so you can assign specific servers to specific roles. For example, a reconnaissance agent might use a domain intelligence server while an analysis agent uses a vulnerability database server.
What happens when an MCP tool call fails during a crew run?
CrewAI wraps tool failures as context for the agent. The LLM receives the error message and can decide to retry with different parameters, fall back to a different tool, or mark the task as partially complete. This resilience is critical for production workflows.
Can CrewAI agents call multiple MCP tools in parallel?
CrewAI agents execute tool calls sequentially within a single reasoning step. However, you can run multiple agents in parallel using process=Process.parallel, each calling different MCP tools concurrently. This is ideal for workflows where separate data sources need to be queried simultaneously.
Can I run CrewAI crews on a schedule (cron)?
Yes. CrewAI crews are standard Python scripts, so you can invoke them via cron, Airflow, Celery, or any task scheduler. The crew.kickoff() method runs synchronously by default, making it straightforward to integrate into existing pipelines.
MCP tools not discovered
Ensure the Edge URL is correct. CrewAI connects lazily when the crew starts. check console output.
Agent not using tools
Make the task description specific. Instead of "do something", say "Use the available tools to list contacts".
Timeout errors
CrewAI has a 10s connection timeout by default. Ensure your network can reach the Edge URL.
Rate limiting or 429 errors
Vinkius enforces per-token rate limits. Check your subscription tier and request quota in the dashboard. Upgrade if you need higher throughput.
