How to Use the AccuWeather MCP in LlamaIndex

Q: How does LlamaIndex index AccuWeather forecast data?

LlamaIndex runs getdailyforecast and converts the JSON output into document nodes. These nodes are then embedded and stored in your vector database for semantic retrieval using the MCP adapter.

Q: Can I use AccuWeather indices to filter LlamaIndex queries?

Yes, you can map outputs from getweatherindices to metadata fields. This allows your agent to filter vector search results based on current outdoor suitability scores.

Q: How do I update the AccuWeather index in LlamaIndex?

Set up a recurring task that calls gethourlyforecast and upserts the new weather data into your index. This keeps your agent's knowledge base fresh and accurate.

Q: How do I resolve city keys before indexing?

Use searchlocation to find the correct key for your target city, then pass that key to your indexing pipeline. This guarantees your vector store indexes the correct geographic data.

Index live AccuWeather forecasts directly into your LlamaIndex vector store using this MCP Server.

Index AccuWeather data for LlamaIndex RAG

Avoid model hallucinations by indexing real-time weather data directly. Your LlamaIndex pipeline can call the `get_daily_forecast` MCP tool and store the output in an index, allowing your agent to query actual forecasts instead of guessing. When users ask about upcoming conditions, the agent queries this vector store. It retrieves coordinates and temperatures fetched via `get_location_by_key`, ensuring every answer is grounded in factual data.

Search historical AccuWeather outputs

By caching the results of `get_weather_alarms` over time, you build a searchable history of severe weather. LlamaIndex lets you run semantic searches over these logged events to find patterns or past warnings. This setup turns transient weather alerts into a structured knowledge base. Your agent can query past alerts alongside your internal documents to assess historical storm impacts.

Structure AccuWeather indices for RAG

Use `get_weather_indices` to pull fitness, outdoor, or travel conditions and index them as document nodes. LlamaIndex parses these nodes, making the categorical ratings searchable for context-aware applications. The agent queries this structured index to answer complex questions about flight delays or hiking safety. It maps the raw numeric values against user preferences stored in your vector database.

Setup guide

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