Perplexity

Automate Pix and Boleto workflows

Chain `efi_create_pix_charge` or `efi_create_boleto` directly into your LangChain agents. The output of your payment generation flows right into the next step of your logic without manual intervention. Your agents decide exactly when to trigger these operations based on user input. It turns your payment process into a programmable event sequence.

Real-time account visibility for LangChain

Use `efi_get_balance` and `efi_get_statement` to feed live financial data into your LangChain agent's memory. Your agents now make decisions based on the actual state of your Efí Pay (Gerencianet) account. This integration allows for immediate reconciliation logic within your chains. You stop guessing about funds and start acting on verified data.

Complex payment orchestration with an MCP Server

Connect your Efí Pay (Gerencianet) MCP Server to manage multi-step transactions. You can verify a balance with `efi_get_balance` before your agent proceeds to send a payment via `efi_send_pix`. This setup ensures your agent handles the entire lifecycle of a transaction. It connects disparate tools into one cohesive, automated pipeline.

Setup guide

Set up Efí Pay (Gerencianet) MCP in LangChain

Prerequisites

Python 3.10+ installed
langchain-mcp-adapters + langgraph packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run pip install langchain-mcp-adapters langgraph langchain-openai. The MCP adapters package converts MCP tools into native LangChain BaseTool objects.
2

Connect via HTTP transport
Use MultiServerMCPClient with "transport": "http" pointing to your Vinkius endpoint. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Create a ReAct agent
Pass the discovered tools to create_react_agent() from LangGraph. The agent automatically routes Efí Pay (Gerencianet) tool calls through the MCP protocol.
4

Run with any LLM
Swap ChatOpenAI for ChatAnthropic, ChatGoogleGenerativeAI, or any LangChain-compatible model. The MCP tools work identically across all providers.

agent.py

from langchain_mcp_adapters.client import MultiServerMCPClient
from langgraph.prebuilt import create_react_agent
from langchain_openai import ChatOpenAI

async with MultiServerMCPClient({
    "efi-pay-gerencianet-mcp": {
        "transport": "http",
        "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp",
    }
}) as client:
    tools = client.get_tools()

    agent = create_react_agent(
        ChatOpenAI(model="gpt-4o"),
        tools,
    )
    result = await agent.ainvoke({
        "messages": "List recent Efí Pay (Gerencianet) transactions"
    })
    print(result["messages"][-1].content)
