How to Use the Fizzpa MCP in LangChain

Q: How does LangChain handle real-time Fizzpa menu updates?

LangChain uses the listcatalogproducts tool inside a ReAct loop to fetch your latest digital menu items. The agent reads this live data to answer customer questions about your food offerings.

Q: Can I trace Fizzpa tool calls in LangChain with LangSmith?

Yes, every execution of tools like createneworder or getorderdetails is fully visible in your LangSmith dashboard. You can inspect the exact inputs, outputs, and token costs for each step.

Q: How do I initialize the Fizzpa MCP Server in LangChain?

Install the adapter using pip install langchain-mcp-adapters langgraph. Then, instantiate MultiServerMCPClient pointing to your Vinkius endpoint and pass the tools to your agent.

Q: What happens if a restaurant customer wants to modify an order?

Your LangChain agent calls updateorderinfo to change the items or customer details. It can then run getorderdetails in the next link of the chain to confirm the changes.

Run multi-step restaurant ordering pipelines in LangChain with live Fizzpa menu and shipping data.

Automate Fizzpa Order Workflows in LangChain

The `create_new_order` tool lets your LangChain agent write new food orders directly to Fizzpa after parsing conversational customer requests. Your agent chains this action directly with `get_shipping_label` to generate fulfillable shipping documents in a single execution loop. LangSmith traces every step of this multi-tool sequence to show you exact latency and token usage for each run. If a customer cancels, the agent invokes `cancel_order` within the same chain to keep your kitchen staff updated instantly.

Keep Digital Menus Synced with Real-Time Stock

The `list_inventory_levels` tool pulls live ingredient counts from your kitchen to prevent overselling on your digital storefront. Your LangChain agent checks these numbers before displaying available dishes, routing the output to update your active catalog. By linking this with `list_catalog_products`, your chain dynamically hides out-of-stock items without manual database edits. This MCP Server connection ensures your AI client never processes an order for a dish you cannot prepare.

Track Kitchen Logistics Across Warehouse Locations

The `list_warehouse_locations` tool maps where your ingredients are stored so the LangChain agent can optimize order routing via this MCP Server. It feeds location data directly into `list_configured_webhooks` to trigger physical prep alerts when stock moves. This integration handles live updates by passing the state from one run to the next using a persistent session. Your agent modifies order details on the fly using `update_order_info` based on real-time kitchen capacity.

Setup guide

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