How to Use the Adafruit IO MCP in LangChain

Q: Can LangChain agents parse raw Adafruit IO data?

Yes. The agent uses the getdata tool to fetch specific values. It then processes that data based on the instructions you define in your chain.

Build complex Adafruit IO chains in LangChain. Connect your feeds directly to multi-step reasoning agents.

Trace your Adafruit IO feed activity

LangChain agents use `list_feeds` and `get_feed` to pull live telemetry into your logic chains. Each interaction leaves a clear record in LangSmith, so you see exactly how the agent parses sensor data. Pass the output of `get_data` directly into other tools in your chain. Your agent decides the next step based on real-time hardware values.

Automate hardware triggers with MCP

Use `list_triggers` to identify active system alerts within your LangChain pipeline. The agent evaluates these triggers before deciding whether to pull more data or stop the process. Connect the MCP server to your graph to create reactive loops. The agent reads status changes and adjusts its behavior without human intervention.

Manage dashboard views via code

Call `list_dashboards` and `get_dashboard` to let your agent inspect the current layout of your hardware monitoring panels. This helps the agent understand the context of your specific device setup. Your agent builds a mental map of your system by iterating through `list_groups`. It organizes complex data structures into actionable insights for your downstream tasks.

Setup guide

Set up Adafruit IO 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 Adafruit IO 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({
    "adafruit-io-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 Adafruit IO transactions"
    })
    print(result["messages"][-1].content)
