How to Use the Treinta App MCP in LangChain

Q: Does LangChain support querying historical transaction data from Treinta App?

Yes, you can chain calls starting with listtransactions to gather book flow data. You then pass that list into another step in your reasoning pipeline for further analysis.

Q: When using Treinta App and LangChain, what is the data privacy guarantee?

The server touches client debt profiles (getclient). All interactions follow Vinkius's zero-trust model. Your agent uses an endpoint token for all calls.

Q: Is it possible for LangChain to process both sales and product creation data?

Absolutely. You can create a chain that first calls listproducts to get the inventory, then uses createproduct to add new SKUs, all before finalizing with a sale using createtransaction.

Connect Treinta App data streams into complex, multi-step reasoning chains with LangChain.

Perplexity

LangChain: Automate full financial cycles.

You can build a chain that first checks the `get_client` debt profile, then uses that information to confirm if the client has sufficient funds. Finally, it calls `create_transaction` for you. This process lets your agent manage complex workflows where the output of one tool—like the client's current balance—becomes the necessary input for the next step in the transaction.

LangChain: Handle inventory adjustments and sales.

Need to record a sale that requires updating stock? Your agent can first call `get_product` to check the current SKU details. Then, it executes `update_product_stock` with the new physical quantity. That whole sequence happens in one chain. This is perfect for complex e-commerce tasks like processing returns or large batch inventory counts.

LangChain: Aggregate business performance reports.

Your agent can run a multi-step query that starts by listing all registered customers using `list_clients`. Next, it takes those IDs and calls `get_business_stats` for each one to build a complete P&L dashboard. This mechanism allows you to combine multiple data sources into a single, actionable report without writing boilerplate code.

Setup guide

Set up Treinta App 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 Treinta App 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({
    "treinta-app-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 Treinta App transactions"
    })
    print(result["messages"][-1].content)
