How to Use the Altoviz MCP in LangChain

Q: How do I connect the Altoviz MCP server to LangChain?

Install the langchain-mcp-adapters package. Initialize MultiServerMCPClient with the Vinkius endpoint URL. Pass the returned tools to your createagent function.

Q: Can LangChain agents read Altoviz invoices automatically?

Yes. You provide the agent with the getsaleinvoicedetails tool. The agent decides when to call it based on the user prompt.

Build multi-step invoicing and customer management pipelines directly in LangChain.

Connect LangChain to business data

The `list_customers` and `get_customer_details` tools pull metadata straight into your LangChain environment. Your ReAct agents need live access to business records. We built this integration so your scripts map client IDs to incoming requests without manual lookups. Output from these MCP tools feeds directly into your next chain link. You might pull a client profile, grab their billing history with `list_sale_invoices`, and pass that raw text to an LLM for summarization. LangSmith tracks the exact latency and token count for every step.

Quote generation via MCP Server

Calling `list_products` fetches your current inventory and pricing tiers. Building a custom quoting agent requires accurate catalogs. The agent reviews the available items before generating a draft. Once the agent selects the right SKUs, it checks `get_sale_quote_details` to verify past discounts offered to that specific buyer. Complex reasoning pipelines handle the math and formatting before human review. You skip the copy-paste routine entirely.

Track expenses across chains

Firing the `list_receipts` tool grabs your recent business expenses. Financial analysis bots rely on clean receipt data. Developers pipe this output into vector stores or SQL databases using standard LangChain document loaders. Supplier management works the exact same way. Querying `list_suppliers` gives your agent the context needed to match receipts to known vendors. The entire workflow stays observable and modular.

Setup guide

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

Common questions about Altoviz MCP in LangChain

Install the `langchain-mcp-adapters` package. Initialize `MultiServerMCPClient` with the Vinkius endpoint URL. Pass the returned tools to your `create_agent` function.

Yes. You provide the agent with the `get_sale_invoice_details` tool. The agent decides when to call it based on the user prompt.

Every tool execution logs directly to LangSmith. You see the exact JSON inputs sent to the server and the response latency.

The tool returns an error string to the agent. ReAct agents typically read this error and retry with different parameters using the MCP standard.

Vinkius runs the server in an ephemeral V8 isolate sandbox. Customer names and billing addresses pulled via `get_customer_details` flow straight to your client. We destroy the sandbox immediately after the request finishes.
