Perplexity

Verify corporate and location data

Feed `get_cnpj_details` into your agent to pull official tax records or use `get_cep_details` to validate shipping addresses instantly. Your agent handles the logic while the SDK guards against unexpected API responses. Since this runs in your production environment, the `get_cnpj_details` tool ensures your agent never guesses company status. It pulls the raw facts from the source.

Check automotive and financial benchmarks

Use `get_fipe_vehicle_price` to inject current market values into your financial evaluation agents. You get precise data without manual lookups. Your agent can also call `list_brazilian_banks` to confirm routing details. It keeps your transaction workflows clean and accurate.

Manage Brazilian scheduling with MCP Server

Call `get_brazilian_holidays` to adjust your agent's task deadlines based on local closures. It prevents scheduling conflicts before they happen. Running this MCP Server inside your agent loop keeps your operational calendar synced. You won't miss a local bank holiday again.

Setup guide

Set up BrasilAPI MCP in OpenAI Agents SDK

Prerequisites

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

1

Install the SDK

Run pip install openai-agents to install the OpenAI Agents SDK. The MCP integration is built-in — no extra dependencies needed.
2

Connect via SSE transport

Use MCPServerSse with your Vinkius endpoint URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. The SDK auto-discovers all BrasilAPI tools at runtime.
3

Create your Agent

Pass the MCP to Agent(mcp_servers=[server]). The agent receives BrasilAPI tools as native definitions — JSON schemas resolve automatically.
4

Run the agent

Call Runner.run(agent, prompt) to execute. The agent invokes the appropriate BrasilAPI tools and returns structured results. Copy the full example on the right to get started.

agent.py

import asyncio
from agents import Agent, Runner
from agents.mcp import MCPServerSse

async def main():
    async with MCPServerSse(
        url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    ) as server:
        agent = Agent(
            name="BrasilAPI Agent",
            instructions="You have access to BrasilAPI tools.",
            mcp_servers=[server],
        )
        result = await Runner.run(agent, "List recent transactions")
        print(result.final_output)

asyncio.run(main())

Common questions about BrasilAPI MCP in OpenAI Agents SDK

The Vinkius gateway handles auth via your endpoint token. You just pass the server params to the agent constructor, and the SDK manages the connection safely.

Yes, set cacheToolsList=True in your config. This prevents redundant requests during complex agent reasoning tasks.

You control the tool list within your agent definition. Simply omit the specific tools you don't need for your current task.

BrasilAPI only processes public institutional data like CEPs, CNPJ numbers, and bank lists. No private user information touches our servers during these lookups.

All requests route through our ephemeral V8 sandbox. Your data never persists, and the execution environment resets after every session.
