How to Use the Commodities MCP in LlamaIndex

Q: How do I index live prices from Commodities into my LlamaIndex vector store?

You use the McpToolSpec to load tools like getgoldprice into LlamaIndex using the MCP protocol. The agent executes the tool, and you can write the returned price data directly into your index as document nodes.

Q: Can I restrict my agent to only look at metal prices?

Yes. You can filter the tools list to only include getpreciousmetalsprices and getcopperprice when initializing your LlamaIndex tool specification.

Index real-time agricultural, energy, and metal prices directly into your LlamaIndex vector stores.

Perplexity

Build RAG Pipelines Grounded in Live Commodities Data

The `list_all_commodities` tool retrieves a clean list of over 30 active asset codes and their respective exchanges. LlamaIndex indexes this structured metadata so your RAG application can map natural language queries to exact market tickers. Instead of relying on static documents, your index stays fresh. When a user queries your data store, the agent pulls live prices using this MCP Server to ground its answers in current market reality.

Feed Real-Time Energy Benchmarks into LlamaIndex

The `get_energy_commodities_prices` tool fetches live WTI, Brent crude, and natural gas prices to update your vector index. Your LlamaIndex agent combines this fresh pricing data with historical PDFs to produce context-aware energy market summaries. By using `get_brent_crude_oil_price` alongside your document indexes, you prevent the model from hallucinating old oil prices. The agent queries the tool, writes the result to memory, and synthesizes the final response.

Track Industrial and Precious Metal Trends

The `get_copper_price` tool delivers current futures data for copper directly to your LlamaIndex query engine. Your agent can compare these industrial metal trends against precious metal data retrieved from `get_precious_metals_prices` to spot macroeconomic shifts. LlamaIndex converts these tool outputs into document nodes on the fly. This lets you run semantic search queries across both live metal prices and your internal research archives.

Setup guide

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