How to Use the Conta Azul MCP in OpenAI Agents SDK

Q: How do I handle pagination when using OpenAI Agents SDK with Conta Azul?

The listcustomers tool returns paginated ERP data that your agent parses iteratively. You configure the agent's system prompt to loop through these pages until it finds the specific corporate entity.

Q: Does the OpenAI Agents SDK support real-time tax queries?

It does when calling the listnfe tool through this MCP integration. The agent fetches government-registered invoices directly, allowing your Python code to process Brazilian tax data in real time.

Connect your OpenAI Agents SDK directly to Conta Azul to manage Brazilian sales, customers, and invoices with built-in guardrails.

Sync Brazilian Customers via OpenAI Agents SDK

The `search_customers` tool lets your OpenAI Agents SDK inspect CPF or CNPJ tax documents directly inside the Conta Azul ERP. Your agent runs these lookups before creating new records to prevent duplicate profiles in your Brazilian sales pipeline. When a new lead signs up, the agent invokes `create_customer` to inject the PF or PJ profile into the system. This directly links the customer's financial limits to their UUID for clean tracking.

Audit Sales and NF-e with this MCP Server

The `list_sales` tool exposes raw transaction logs to your OpenAI Agents SDK for automated reconciliation. By parsing this live stream, your agent flags pending invoices and matches them against incoming bank deposits. To verify tax compliance, the agent calls `list_nfe` to pull government-issued invoices. The OpenAI dashboard traces these calls to guarantee your automated tax auditing matches real-world Brazilian government records.

Monitor Recurring Contracts via OpenAI Agents SDK

The `list_contracts` tool feeds active, recurring Brazilian client agreements directly into your OpenAI Agents SDK runtime. This lets your agent track payment schedules and automatically flag accounts nearing their credit limits. When billing anomalies occur, the agent runs `get_sale` to inspect the exact accounting matrices of the disputed invoice. This setup keeps your automated billing loops accurate without human intervention.

Setup guide

Set up Conta Azul 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 Conta Azul tools at runtime.
3

Create your Agent

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

Run the agent

Call Runner.run(agent, prompt) to execute. The agent invokes the appropriate Conta Azul 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="Conta Azul Agent",
            instructions="You have access to Conta Azul tools.",
            mcp_servers=[server],
        )
        result = await Runner.run(agent, "List recent transactions")
        print(result.final_output)

asyncio.run(main())

Common questions about Conta Azul MCP in OpenAI Agents SDK

You pass your Vinkius token to the MCPServerStreamableHttp constructor in your Python code. This single token handles the underlying OAuth handshake with the Brazilian ERP, letting your agent call tools like `list_bank_accounts` instantly.

Yes, you configure guardrails directly inside the agent constructor when initializing the MCP server. This prevents the agent from calling destructive tools or making unauthorized changes to your `create_product` catalog.

The `list_customers` tool returns paginated ERP data that your agent parses iteratively. You configure the agent's system prompt to loop through these pages until it finds the specific corporate entity.

It does when calling the `list_nfe` tool through this MCP integration. The agent fetches government-registered invoices directly, allowing your Python code to process Brazilian tax data in real time.

Vinkius runs the Conta Azul MCP server inside a sandboxed V8 isolate, meaning CNPJ details from `search_customers` never persist on external disks. All financial data remains ephemeral, transmitting encrypted payloads directly between your Python agent and the ERP API.
