Chain wholesale lookups with LangChain

This MCP Server connects your LangChain agent to `list_orders` and `get_order` to automate order fulfillment pipelines. The output of an order lookup feeds directly into the next step of your chain, letting your agent inspect line items and customer details in a single execution loop. You trace the entire execution path in LangSmith to monitor latency and token usage. If an order lacks sufficient stock, your agent triggers a follow-up step to find alternative items without manual intervention.

Automate stock adjustments in LangGraph

Running `list_inventory` and `update_inventory` lets your LangGraph state machines modify wholesale stock levels based on live sales events. Your agent reads the current inventory, evaluates it against pending requests, and pushes the updated quantities straight back to Fieldfolio. Because LangChain handles state transition, you can build loops that check stock before writing changes. This prevents race conditions when multiple wholesale orders process at the same time.

Search catalogs using LangChain agents

Calling `search_catalog` and `list_products` exposes your entire Fieldfolio wholesale catalog to LangChain's tool-calling agents. Your agent searches by keyword, filters by category using `list_categories`, and retrieves specific product metadata on demand. This setup lets you build conversational catalog search systems for your sales team. They ask questions in plain English, and the agent translates those requests into precise API queries.

Setup guide

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

Common questions about Fieldfolio MCP in LangChain

Install the adapter package and initialize the client with your Vinkius endpoint. Retrieve the tools using the client instance and pass them directly into your agent configuration.

Yes, you can mix these tools with any of LangChain's existing integrations. This lets your chain take an order payload and immediately push it to your accounting or shipping services.

You manage rate limits by wrapping your tool calls in custom LangGraph nodes with built-in retry logic. This prevents inventory updates from failing during high-volume wholesale events.

The multi-server client aggregates tools from different MCP sources into one list. This lets your agent coordinate actions across different accounts or platforms alongside your wholesale catalog.

All wholesale order details and transaction records remain inside the secure V8 Isolate Sandbox on Vinkius. Your API keys and purchase histories are never logged in plain text or exposed to external servers.
