Chain pension rules directly into LangChain agents

Stop guessing how cross-border retirement works. This MCP connects your agent to actual statutory guidelines in the UK, Germany, France, and Spain. By chaining `get_scheme_details` with your existing database lookups, you can automatically pull the exact retirement ages and rules for each jurisdiction without writing custom API wrappers. Your agent evaluates the raw regulatory parameters first. Then, it feeds that data directly into subsequent steps to map out a user's multi-national employment history. It keeps your financial planning pipelines grounded in real, current legislation.

Calculate benefits across multiple steps

Let's run the numbers. When you calculate retirement income, a single API call is never enough. This MCP lets your LangChain agent use `calculate_monthly_benefit` as a middle link in a complex financial advisory chain. The output flows directly into your next tool, like a tax estimator or a private savings calculator. You get a clear, multi-step projection of a client's future cash flow, tracked step-by-step through LangSmith.

Analyze the cost of retiring early

The math doesn't lie, and missing a few years of contributions can devastate a retirement plan. This MCP gives your agent the ability to invoke `assess_contribution_gap` to show clients exactly what they lose if they stop working early. This tool computes the exact financial impact of working extra years. It gives your agent the raw data needed to advise clients on whether buying back missing years is actually worth the cash.

Setup guide

Set up European Pension Estimator 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 European Pension Estimator 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({
    "european-pension-estimator-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 European Pension Estimator transactions"
    })
    print(result["messages"][-1].content)
