How to Use the Alexa Smart Home MCP in LangChain

Q: Can I use Alexa Smart Home with LangChain to toggle lights?

Yes, you can trigger turnonalexadevice or turnoffalexadevice through your agent. Simply define the tool in your chain and let the model handle the toggling based on your instructions.

Q: Will my LangChain agent work with Alexa Smart Home sensors?

Absolutely. You can call gettemperaturesensor to pull real-time data into your agent's context. This allows your logic to react to environmental changes in your home.

Chain your smart home actions directly into LangChain agents for automated, multi-step routines across your devices.

Automate device state sequences in LangChain

You can now chain complex smart home tasks by feeding outputs from `list_alexa_devices` directly into control commands. This lets your agent determine the correct endpoint ID before executing a state change, removing the need for manual lookups. Your chains handle the logic of checking current conditions before acting. For example, the agent can run `get_thermostat_state` and only trigger a heating change if the temperature drops below a specific threshold.

Observe Alexa Smart Home tool execution

Every interaction with your hardware is logged through your tracing stack, giving you full visibility into how the agent manages your gear. You see exactly when `turn_on_alexa_device` was invoked and what the response was. This visibility helps you debug failed requests or unexpected behaviors in your automation logic. You get a clear audit trail of every tool call made by the agent.

Manage your entire home configuration

Update your device setup without leaving your development environment by using `update_alexa_device_name` or `update_device_room`. This keeps your smart home organized as you add or move hardware. Your agent keeps the records accurate by syncing your local environment with the actual state of your connected devices. It’s a direct way to maintain your smart property registry.

Setup guide

Set up Alexa Smart Home 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 Alexa Smart Home 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({
    "alexa-smart-home-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 Alexa Smart Home transactions"
    })
    print(result["messages"][-1].content)
