Run dynamic power cost chains in LangChain

The `calculate_daily_consumption` tool calculates the energy consumption of an appliance in one day based on wattage and usage hours. Your LangChain agent can pipe this exact daily kilowatt-hour figure directly into subsequent math steps or external database lookups without manual copy-pasting. By feeding this daily metric straight into your chains, you get immediate visibility into active power hogs. You can trace these exact data flows inside LangSmith to see how your agent calculates load before suggesting budget adjustments.

Calculate monthly utility bills automatically

The `calculate_monthly_expenses` tool calculates the monthly electricity cost for a given energy usage by applying regional utility tariff estimates. Your LangChain ReAct agent uses this output to build multi-step financial models that project annual household overhead. This tool allows your agent to run complex budgeting pipelines. You can combine it with other integrations in your chain to store the final expense projections directly in your local SQL database.

Map complete appliance profiles with this MCP Server

The `get_appliance_impact_summary` tool gives you a complete energy and cost summary for an appliance, combining both consumption and financial metrics in one shot. It gives your agent a detailed breakdown of how much a specific machine costs to run over its lifespan. This MCP helps your agent draw up immediate comparisons between old, inefficient appliances and modern replacements. You get the raw data needed to advise clients on whether a new refrigerator pays for itself in utility savings.

Setup guide

Set up Appliance Energy Calculator 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 Appliance Energy Calculator 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({
    "appliance-energy-calculator-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 Appliance Energy Calculator transactions"
    })
    print(result["messages"][-1].content)

Common questions about Appliance Energy Calculator MCP in LangChain

Run pip install langchain-mcp-adapters langgraph in your terminal. Then, configure the MultiServerMCPClient with the transport URL to start querying the tools.

Yes. The agent uses the calculations to project monthly costs, which you can then pass to custom logic chains that handle tiered billing structures.

It forces your agent to rely on concrete math instead of guessing wattages. The agent pulls real numbers directly from the tools rather than generating random estimates.

Absolutely. You can chain these calculations with local database queries or weather APIs to predict heating costs during winter spikes.

This MCP only processes raw numbers like wattage, daily run hours, and regional tariff variables. Your personal household identity and physical address are never transmitted or stored.
