LangChain ReAct Agents

This MCP calculates massive financial penalties triggered when you ignore federal notice periods. Your LangChain agent can now audit planned workforce reductions before HR sends a single email. Let's be real. Companies bleed cash because executives guess at compliance instead of running the actual numbers. You build a multi-step reasoning pipeline. The agent ingests your termination list and calls `check_warn_compliance` to determine if the event violates federal thresholds. It stops the chain immediately upon detecting illegal notice windows.

Math-First Liability in this MCP Server

HR double-speak won't save you in federal court, and the math doesn't lie. Your composable chains need concrete liability figures to weigh alternative severance packages. Pass the termination dates into `calculate_employee_backpay_liability` to get exact dollar amounts owed. Every step is visible via LangSmith tracing. You see the token usage, latency, and exactly how much back pay exposure your proposed layoff creates.

Pipeline Execution

Stop guessing at your legal risk with this MCP. Bottom line: you need an urgent, final compliance audit before executing any reduction in force. Your agent decides the order of operations based on intermediate findings. If the initial audit flags a violation, the chain automatically invokes `calculate_civil_penalty_exposure` to estimate local government fines. Legal teams receive the total cost of non-compliance delivered straight to their inbox.

Setup guide

Set up US WARN Act Compliance Calculator 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 US WARN Act Compliance Calculator 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({
    "us-warn-act-compliance-calculator-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 US WARN Act Compliance Calculator transactions"
    })
    print(result["messages"][-1].content)
