Perplexity

Automated tax document issuance

Trigger `emit_nfce` and `emit_nfcom` directly from your agent logic to handle retail and telecom invoices. Your agent handles the payload generation, ensuring the Focus Varejo API receives the correct structure for every transaction. This setup removes manual data entry for store managers. Your agent validates the output against the schema before hitting the endpoint, keeping your records clean and compliant.

Real-time document status management

Use `consult_nfce` and `consult_nfcom` to track the lifecycle of every invoice in your pipeline. Your agent fetches the current state, letting it decide whether to retry a failed operation or notify an admin. This provides a clear audit trail for every document. You get immediate visibility into tax status without querying the dashboard manually.

Logistics and inbound document control

Manage your supply chain by using `manifest_nfe` and `manifest_cte` to acknowledge inbound shipments. Your agent confirms receipt and updates your internal system records automatically. This keeps your inventory logs synchronized with actual deliveries. You avoid discrepancies by processing inbound documents as soon as they appear in the system.

Setup guide

Set up Focus Varejo 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 Focus Varejo tools at runtime.
3

Create your Agent

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

Run the agent

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

asyncio.run(main())
