Automate order lifecycles in LangChain

Chain `create_order` and `cancel_order` within your LangGraph pipelines to manage lay-by requests without manual intervention. The agent evaluates order states before triggering transitions. This setup ensures your agent handles the entire lifecycle, from initialization to voiding, based on the logic you define. You gain full observability over every step using standard tracing.

Sequence financial data with Layup

Pipe the output of `list_payments` directly into `create_deposit` to reconcile accounts automatically. This workflow lets your agent process incoming funds as part of a larger chain. Your agent decides when to execute these calls based on the specific needs of your retail workflow. It keeps the transaction flow moving without requiring you to write custom glue code.

Fetch customer context for LangChain

Use `list_customers` and `get_customer` to pull shopper details into your prompt context. Your agent uses this data to personalize responses or verify identity before modifying orders. This integration allows for dynamic decision-making during customer interactions. You connect these tools to your databases or vector stores to build a complete picture of the shopper.

Setup guide

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

Common questions about Layup MCP in LangChain

Install the necessary MCP adapters and initialize the client pointing to your server. Once connected, fetch the tool list and pass it directly to your agent constructor to enable the integration.

Yes, you can aggregate multiple MCP servers into a single client. This lets your agent call Layup tools alongside other external services in one unified pipeline.

The server remains stateless by default. You should use the client session feature if your agent needs to maintain context across multiple turns or complex chains.

The server currently relies on backend throttling. You must implement retry logic within your chain to handle cases where the API response time exceeds your defined thresholds.

Your customer checkout data is handled through an ephemeral sandbox. We use endpoint tokens for authentication and never store your raw credentials within the agent environment.
