How to Use the Konfío MCP in LangChain

Q: How do I use Konfío tools with a LangChain agent?

First, install the adapter and create a MultiServerMCPClient for the MCP server. Then, call client.gettools() to get the list of Konfío functions and pass that tool list directly into your agent executor.

Q: Can my LangChain agent create Mexican invoices with Konfío?

Yes, that's what the createinvoice tool is for. Your agent can call it with the required client RFC, tax details, and items to generate a valid CFDI. It's designed specifically for compliance with SAT regulations.

Q: What's the best way to manage loan payments with Konfío and LangChain?

Create a chain. Have the agent call listloans to find the loan ID, then getpaymentschedule to see the next due date, and finally execute makeloanpayment with the correct details.

Chain Financial Operations

Connect Konfío tools into a single, logical sequence. Your LangChain agent can `check_credit_status`, then automatically `request_credit_line` if you're eligible, and finally `get_loan_details` to confirm the terms. You're not just calling tools; you're building a workflow. The output from one tool becomes the input for the next. For instance, get a loan ID from `list_loans` and pass it directly to `make_loan_payment`. With LangSmith, you can trace the entire execution, see exactly what the agent decided, and debug any step in the chain.

Automate Invoicing and Payments

Stop managing invoices by hand. Set up a ReAct agent that pulls client data, uses `create_invoice` to generate a SAT-compliant CFDI, and monitors its status. The agent handles the details, you just give it the goal. You can also automate accounts payable. Your agent can `list_invoices` from suppliers, and when you approve one, it uses `create_transfer` to schedule the SPEI payment. It's a simple chain that takes care of a core business task.

Build Custom Agents with this MCP Server

The Konfío MCP Server gives your LangChain agent 14 distinct financial operations. You can build a specialized agent for managing debt that only has access to `list_loans` and `make_loan_payment`, or an agent for expense tracking using `list_cc_transactions`. Because you get the tools by calling `client.get_tools()`, you can programmatically decide which functions to give your agent for any given task. This lets you build safer, more focused automations that have just enough permission to get the job done.

Setup guide

Set up Konfío 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 Konfío 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({
    "konfio-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 Konfío transactions"
    })
    print(result["messages"][-1].content)
