How to Use the NFe.io MCP in OpenAI Agents SDK

Q: How does NFe.io integrate with OpenAI Agents SDK?

You connect the server using the MCPServerStreamableHttp class. The agent auto-discovers all 10 tools, making the NFe.io endpoints immediately available for your logic.

Q: Can OpenAI Agents SDK use NFe.io to cancel invoices?

Yes, you can trigger cancelserviceinvoice or cancelmerchandiseinvoice through the agent. The tool performs the action on the NFe.io platform as soon as the agent calls it.

Q: Does NFe.io provide logs for OpenAI Agents SDK?

The server exposes listwebhooks so your agent can verify event tracking. You can cross-reference these with your own logs to maintain an audit trail.

Automate invoice lifecycle in OpenAI Agents SDK

Trigger `issue_service_invoice` or `issue_merchandise_invoice` directly from your agent logic. Your agent handles the tax documentation flow without manual intervention. This MCP Server connects your agent's decision-making process to actual NFe.io endpoints. It removes the need for custom API wrappers.

Validate company data for OpenAI Agents SDK

Use `get_company_details` to pull registration status before your agent starts an invoice run. This keeps your agent informed about the issuer's current standing. `list_companies` gives your agent the full context of available issuers. It ensures your logic targets the correct account every time.

Real-time visibility for OpenAI Agents SDK

Use `list_webhooks` to verify that your NFe.io notifications are active. Your agent can monitor the health of your integration status. `get_service_invoice` allows your agent to check the status of specific tax documents. It turns your agent into an active auditor of your financial records.

Setup guide

Set up NFe.io 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 NFe.io tools at runtime.
3

Create your Agent

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

Run the agent

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

asyncio.run(main())
