Advanced Multi-Step Data Queries for LangChain

You'll build reasoning pipelines where the agent decides which tool to call and in what order. For instance, you can first use `get_gdp` to pinpoint a regional dip, then immediately pass those coordinates into `get_retail_sales` to see if consumer spending dropped concurrently. This capability lets your agent perform complex economic modeling—it's not just fetching data; it’s linking disparate sources. You can combine the results of `get_business_counts` with `get_cpih` observations in a single, automated chain.

Modeling Household Finance and Welfare via MCP Server

The agent handles multi-server aggregation by chaining together finance indicators. Need to assess income stability? You can start with `get_tax_benefits` results, then follow up by querying weekly spending patterns using `get_spending_cards`. The chain builds a full picture of financial flow. This sequential process is perfect for simulating economic shocks. You’ll pass the output from one ONS dataset—say, regional GDP figures—directly into another tool to calculate variance over time.

Discovering Data Connections with LangChain

Need to know what data is available before writing a single line of code? The agent uses `list_datasets` and `get_dimensions` to map out the entire ONS catalog. It figures out which filters you need for a specific region or time period. This discovery process saves hours of manual investigation. You'll use this knowledge to accurately structure calls to other tools, like figuring out the precise dimension IDs needed before running `get_observations`.

Setup guide

Set up UK ONS Full — Complete Statistical Intelligence MCP in LangChain

Prerequisites

Python 3.10+ installed
langchain-mcp-adapters + langgraph packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run pip install langchain-mcp-adapters langgraph langchain-openai. The MCP adapters package converts MCP tools into native LangChain BaseTool objects.
2

Connect via HTTP transport
Use MultiServerMCPClient with "transport": "http" pointing to your Vinkius endpoint. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Create a ReAct agent
Pass the discovered tools to create_react_agent() from LangGraph. The agent automatically routes UK ONS Full — Complete Statistical Intelligence tool calls through the MCP protocol.
4

Run with any LLM
Swap ChatOpenAI for ChatAnthropic, ChatGoogleGenerativeAI, or any LangChain-compatible model. The MCP tools work identically across all providers.

agent.py

from langchain_mcp_adapters.client import MultiServerMCPClient
from langgraph.prebuilt import create_react_agent
from langchain_openai import ChatOpenAI

async with MultiServerMCPClient({
    "uk-ons-full-complete-statistical-intelligence-mcp": {
        "transport": "http",
        "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp",
    }
}) as client:
    tools = client.get_tools()

    agent = create_react_agent(
        ChatOpenAI(model="gpt-4o"),
        tools,
    )
    result = await agent.ainvoke({
        "messages": "List recent UK ONS Full — Complete Statistical Intelligence transactions"
    })
    print(result["messages"][-1].content)

Common questions about UK ONS Full — Complete Statistical Intelligence MCP in LangChain

LangChain allows your agent to treat the MCP Server as a series of linked tools. You don't just get one answer; you build an entire narrative, passing inputs from `get_gdp` into subsequent calls like `get_trade`. It makes complex economic reasoning possible.

Absolutely. The server provides 20 tools covering everything from CPIH to wellbeing. Your agent can autonomously decide the best path through these datasets, managing the entire query flow without human intervention.

The server handles broad economic statistics, including regional GDP, inflation metrics (`get_cpih`), and household spending patterns. It's a mix of population metrics, trade figures, and consumer activity.

Yes. The MCP Server is designed for integration into agent frameworks like LangChain. Your client calls `client.get_tools()` and passes them directly to the agent constructor.

The server accesses aggregated economic statistics, such as regional GDP or national CPIH figures. It does not touch private individual-level identifiers.
