Chain tax logic into your agents

Trigger `calculate_tax_comparison` as a node in your LangChain pipeline to determine liability differences between Sole Proprietorships and Corporations. The agent passes revenue data directly into the calculation flow for instant results. You can chain these outputs to trigger secondary logic based on the tax delta. This keeps your agent-driven workflows grounded in real financial math rather than estimates.

Quantify S-Corp benefits

Feed specific salary and distribution figures into `evaluate_s_corp_savings_potential` to see exactly how much FICA tax you might save. The agent uses this data to decide if an S-Corp election makes sense for the current tax year. This tool output serves as a clear decision gate within your agent loops. It removes guesswork from the planning process by providing a numeric baseline for your tax strategy.

Contextualize state tax environments

Fetch local filing requirements and rates using `get_state_tax_context` to ground your agent in specific jurisdictional rules. This data becomes a reliable input for any multi-step reasoning task. Your agent uses this context to refine its tax models based on where the business actually operates. It ensures that every calculation accounts for regional variations in tax law.

Setup guide

Set up US LLC Tax Comparator 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 LLC Tax Comparator 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-llc-tax-comparator-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 LLC Tax Comparator transactions"
    })
