Indexable tax simulations

Call `compare_tax_regimes` and feed the output directly into your vector store. Your agents now have a searchable history of past fiscal scenarios to reference when planning for the next quarter. This turns transient simulation data into a persistent knowledge base. You won't have to rerun the same numbers twice when you're looking for trends in your historical tax efficiency.

Deep fiscal intelligence

Use `get_regime_breakdown` to build a semantic index of your tax components. When you ask your agent about specific deductions, it retrieves data grounded in the actual regime breakdown. It’s a better way to manage your financial documents. Instead of sifting through reports, you just query your index and get the exact tax breakdown you need.

Unified financial context

Combine this MCP with your internal documents in a single LlamaIndex application. The agent uses the `compare_tax_regimes` output alongside your company policy to provide context-aware tax advice. This prevents the agent from hallucinating figures. It pulls from your actual data, ensuring your financial planning is based on hard numbers rather than generic assumptions.

Setup guide

Set up Tax Regime Comparator MCP in LlamaIndex

Prerequisites

Python 3.10+ installed
llama-index-tools-mcp package
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run pip install llama-index-tools-mcp llama-index-llms-openai. The MCP tools package provides BasicMCPClient and McpToolSpec.
2

Connect with BasicMCPClient
Point BasicMCPClient to your Vinkius endpoint URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. Supports SSE and Streamable HTTP transports.
3

Convert to LlamaIndex tools
Call mcp_tool_spec.to_tool_list_async() to convert all Tax Regime Comparator MCP tools into native FunctionTool objects that any LlamaIndex agent can use.
4

Run with any LLM
Create a FunctionAgent with the tools and your preferred LLM. Swap OpenAI for Anthropic, Gemini, or any LlamaIndex-supported provider.

agent.py

from llama_index.tools.mcp import BasicMCPClient, McpToolSpec
from llama_index.core.agent.workflow import FunctionAgent
from llama_index.llms.openai import OpenAI

# Connect to the MCP
mcp_client = BasicMCPClient(
    "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
)
mcp_tool_spec = McpToolSpec(client=mcp_client)

# Convert MCP tools to LlamaIndex tools
tools = await mcp_tool_spec.to_tool_list_async()

# Create and run the agent
agent = FunctionAgent(
    tools=tools,
    llm=OpenAI(model="gpt-4o"),
    system_prompt="You have access to Tax Regime Comparator tools.",
)
response = await agent.run("List recent Tax Regime Comparator data")

Common questions about Tax Regime Comparator MCP in LlamaIndex

You use the McpToolSpec to load the tools into your agent, allowing the results to be indexed as part of your RAG pipeline. This makes your tax data queryable alongside your other business documents.

Once you index the tool outputs, you can perform semantic searches across all your previous simulations. It’s a fast way to see how your tax strategy has evolved over time.

Your indexed data stays within your controlled storage environment. We do not touch your financial records; the MCP simply acts as a bridge to pull the data you request.

This MCP handles numeric inputs related to your corporate revenue, expenses, and tax regime parameters. It treats this information as transient data for the duration of your calculation.

You just need the standard MCP client tools for LlamaIndex to bridge the connection. Once connected, your tools are ready to be indexed and queried immediately.
