Index regional labor metrics for grounded RAG

The `query_bls` tool fetches raw Local Area Unemployment Statistics timeseries directly into your LlamaIndex pipeline. Your agent takes these raw metrics and indexes them into your vector store, turning ephemeral API data into searchable, persistent knowledge. This process prevents your agent from hallucinating local employment figures. Instead of guessing, the system queries the actual indexed timeseries data to answer complex regional economic questions.

Combine live BLS data with documents in LlamaIndex

The `query_bls` tool integrates directly with your LlamaIndex document readers to create a unified data index. Your agent can query local unemployment rates alongside regional housing reports to find correlations between job losses and market trends. Setting this up requires the `llama-index-tools-mcp` package to expose the tool to your `FunctionAgent`. The agent uses the live data to ground its responses, ensuring your financial reports reflect current government statistics.

Query historical county trends using this MCP Server

The `query_bls` tool allows you to retrieve up to 50 concurrent lookbacks of county-level unemployment statistics. Your LlamaIndex agent can parse these historical data points and store them as nodes in your index for semantic retrieval. This server acts as a bridge, translating raw BLS API payloads into structured data that LlamaIndex can easily ingest. You get clean, structured economic timeseries data ready for vector embedding.

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 Local — LAUS State & County Unemployment tools.",
)
response = await agent.run("List recent BLS Local — LAUS State & County Unemployment data")
