LlamaIndex integration with BLS Public Data API

Use `get_bls_timeseries_data` to inject economic figures into your retrieval-augmented generation workflow. Your index grows as you pull new series data. Your RAG application now grounds its answers in real-time labor stats. You avoid hallucinations by referencing the exact data retrieved.

Confirm BLS Public Data API status for LlamaIndex

Run `check_api_status` to ensure your knowledge base updates only when the source is online. This keeps your pipeline reliable during automated indexing runs. You avoid corrupting your vector store with empty or error-filled responses. It acts as a gatekeeper for your data ingestion.

Query historical data via LlamaIndex

Turn API outputs into searchable documents by passing them through the tool spec. Your agent searches these past results to answer complex questions about market trends. Searching your indexed history beats fetching fresh data every time. You save on API calls while keeping your knowledge base current.

Setup guide

Set up BLS Public Data API 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 BLS Public Data API 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 BLS Public Data API tools.",
)
response = await agent.run("List recent BLS Public Data API data")
