Build complex tax chains with LangChain

You get a complete year-by-year depreciation schedule by passing asset details through `calculate_depreciation_schedule` directly inside your agent chain using this MCP. Your agent handles the math and structures the output for your reports. LangSmith traces every step of this calculation so you can audit the token usage and intermediate variables in real time.

Compare tax deduction strategies in your pipelines

Look, the math is simple when you run `calculate_expensing_impact` to compare Section 179 and Bonus Depreciation against standard MACRS using this MCP. The logic executes inside your existing chains, letting the agent decide which deduction strategy yields the best first-year write-off. You get hard numbers to present to your clients without running separate offline spreadsheets.

Determine asset lifespans dynamically

According to the tax code, classifying assets correctly is half the battle, which is why your agent uses `get_asset_class_info` to identify recovery periods. The tool identifies whether an asset is a vehicle, residential property, or commercial building. This MCP setup eliminates manual lookups and prevents classification errors from corrupting your tax projections.

Setup guide

Set up US Depreciation 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 Depreciation 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-depreciation-calculator-mcp": {
        "transport": "http",
        "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp",
    }
