How to Use the GrabFood Partner MCP in LangChain

Q: Can a LangChain pipeline handle GrabFood Partner order cancellations?

Yes. The agent uses checkordercancelable to verify the state before invoking cancelorder. This two-step chain prevents API errors and protects your merchant performance rating.

Q: What happens if my kitchen gets overwhelmed during a rush?

Your agent can call pausestore with pause set to true to temporarily halt incoming orders. Once the queue clears, the chain triggers an unpause to open your storefront back up.

Chain GrabFood Partner operational tools directly into your LangChain pipelines using this MCP Server to automate orders and menu changes on the fly.

Perplexity

Automate order acceptance in LangChain

The `accept_order` tool lets your LangChain agent confirm or reject incoming orders based on live kitchen bandwidth. When a new order triggers your pipeline, the agent runs a quick check on active kitchen tickets and instantly executes the decision. By feeding the output of this tool into your next chain link, you can dynamically update your preparation queue. The agent handles the decision in real-time, removing the need for manual tablet taps during a busy dinner rush.

Perform batch menu updates inside active chains

The `batch_update_menu` tool modifies specific item prices and availability without replacing the entire menu structure. Your agent runs this tool inside a LangChain sequence backed by our MCP Server when upstream inventory logs signal that an ingredient is out of stock. Because this runs inside an integrated flow, the success payload can immediately trigger a notification to your staff. This prevents zombie menu items from lingering on the app and causing customer friction.

Manage driver dispatch timing dynamically

The `update_ready_time` tool sends an updated food preparation estimate to GrabFood so drivers arrive exactly when the kitchen finishes packing. When LangSmith tracing flags a spike in prep latency, your agent adjusts the ready timestamp automatically. This direct integration keeps your delivery metrics clean. It stops drivers from crowding your lobby while waiting on complex orders that take longer than the default platform estimate.

Setup guide

Set up GrabFood Partner 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 GrabFood Partner 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({
    "grabfood-partner-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 GrabFood Partner transactions"
    })
    print(result["messages"][-1].content)
