How to Use the Tomorrow.io Alternative MCP in LlamaIndex

Q: Can I use Tomorrow.io Alternative’s forecasts with LlamaIndex?

Yes. You can call getforecast and index those temperature, wind, and humidity readings. Your application then treats the forecast data like any other document, making it queryable.

Q: What kind of historical weather data is available for LlamaIndex?

You can use gethistoricalweather to pull observations over specific date ranges. Indexing this allows users to ask precise questions about past climate conditions, linking API data to their documents.

Q: Is Tomorrow.io Alternative suitable for knowledge augmentation in LlamaIndex?

It's perfect. By indexing tools like gethourlyforecast, you combine real-time meteorological data with proprietary company reports, creating a unified source of truth.

Perplexity

Build a knowledge base from live weather data.

Instead of just calling `get_daily_forecast`, you index its output directly into your vector store. This means past forecast results become searchable knowledge, allowing users to query historical API data alongside their documents.

Query complex event history with LlamaIndex.

Need to know if a specific area saw severe weather last year? Use `get_recent_history` and index the results. Your RAG application can then answer questions like, 'What was the precipitation in Miami during the hurricane season of 2023?'

Index route data for advanced search.

Don't just plan a trip; index the entire weather profile. Run `get_route_weather` and store the waypoints, timings, and associated forecasts. This lets your knowledge base answer questions about optimal travel routes based on historical conditions.

Setup guide

Set up Tomorrow.io Alternative MCP in LlamaIndex

Prerequisites

Python 3.10+ installed
llama-index-tools-mcp package
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run pip install llama-index-tools-mcp llama-index-llms-openai. The MCP tools package provides BasicMCPClient and McpToolSpec.
2

Connect with BasicMCPClient
Point BasicMCPClient to your Vinkius endpoint URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. Supports SSE and Streamable HTTP transports.
3

Convert to LlamaIndex tools
Call mcp_tool_spec.to_tool_list_async() to convert all Tomorrow.io Alternative MCP tools into native FunctionTool objects that any LlamaIndex agent can use.
4

Run with any LLM
Create a FunctionAgent with the tools and your preferred LLM. Swap OpenAI for Anthropic, Gemini, or any LlamaIndex-supported provider.

agent.py

from llama_index.tools.mcp import BasicMCPClient, McpToolSpec
from llama_index.core.agent.workflow import FunctionAgent
from llama_index.llms.openai import OpenAI

# Connect to the MCP
mcp_client = BasicMCPClient(
    "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
)
mcp_tool_spec = McpToolSpec(client=mcp_client)

# Convert MCP tools to LlamaIndex tools
tools = await mcp_tool_spec.to_tool_list_async()

# Create and run the agent
agent = FunctionAgent(
    tools=tools,
    llm=OpenAI(model="gpt-4o"),
    system_prompt="You have access to Tomorrow.io Alternative tools.",
)
response = await agent.run("List recent Tomorrow.io Alternative data")
