Perplexity

Automate complex data gathering using the MCP Server.

Your agent can build full planning pipelines by linking multiple tool calls. For instance, you can first call `get_daily_forecast` to check general travel viability, and then use that location data to feed into `get_route_weather`. The output of one step becomes the precise input for the next.

Build advanced logistics chains with LangChain.

Need a detailed plan for deliveries? Use `get_route_weather` by feeding it waypoints and times. This lets your agent figure out if the route is viable before sending anything. It’s perfect for simulating complex supply chain decisions.

Analyze historical data in sequence.

For research or insurance claims, you can run a multi-step query. Start by calling `get_historical_weather` to define the date range needed. Then, use that raw data set to feed into `get_timeline`, allowing your agent to pull out specific fields like wind speed and humidity for analysis.

Setup guide

Set up Tomorrow.io Alternative 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 Tomorrow.io Alternative 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({
    "tomorrowio-alternative-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 Tomorrow.io Alternative transactions"
    })
    print(result["messages"][-1].content)
