How to Use the Weatherbit MCP in LlamaIndex

Q: Can LlamaIndex handle severe weather reports from Weatherbit?

Yes. After running getsevereweather, the resulting report details—including severity and affected areas—are added to your index, making them part of your searchable knowledge.

Q: Does LlamaIndex help with multi-location data?

It does. You can run forecasts for multiple cities (e.g., getforecastdailybycity) and index all the results into one unified knowledge base.

Perplexity

Build a searchable index of historical data

The `get_historical_weather` tool retrieves temperature, precipitation, and wind metrics for the past 30 years. When you pass this output to LlamaIndex, it becomes part of your vector store. This means you can query complex questions like 'What was the average rainfall in June 2015?' and get an answer grounded in actual API data.

Query current weather conditions with MCP Server

`get_current_weather` reports temperature, humidity, wind speed/direction, and visibility for a given location. Indexing this output allows users to ask follow-up questions about the context. Instead of just getting a list of data points, LlamaIndex lets you query semantic knowledge built from that weather report.

Track multiple forecasts with LlamaIndex

You can index daily and hourly predictions using tools like `get_forecast_daily` or `get_forecast_hourly`. The resulting data—including temperature ranges and precipitation probabilities—is added to your knowledge base. This creates a unified, queryable index where users can ask about weather patterns across months or years.

Setup guide

Set up Weatherbit 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 Weatherbit 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 Weatherbit tools.",
)
response = await agent.run("List recent Weatherbit data")
