Perplexity

Ground your index in public data

Feed the output of your HHS queries directly into your LlamaIndex vector store. Use `get_catalog` to locate the exact dataset you need for your RAG application. By indexing the results of `query_dataset`, you ensure your agent answers questions based on verified government data. This keeps your knowledge base updated with the latest public statistics.

Query historical health records

Use this MCP server to retrieve specific historical data points from HealthData.gov (HHS Open Data). You can filter these records using SoQL to focus on specific timeframes or regions. After retrieval, your LlamaIndex agent creates a semantic representation of these records. This allows you to perform natural language queries against a massive repository of health information.

Automate data discovery for RAG

Let your LlamaIndex agent find new datasets using `get_catalog` during the ingestion phase. It can scan the catalog for updated hospital capacity or infection rate records. Once discovered, the agent uses `query_dataset` to ingest the raw numbers into your index. This cycle keeps your RAG application current without manual intervention.

Setup guide

Set up HealthData.gov (HHS Open Data) 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 HealthData.gov (HHS Open Data) 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 HealthData.gov (HHS Open Data) tools.",
)
response = await agent.run("List recent HealthData.gov (HHS Open Data) data")
