Model tax regimes with Google ADK

Your agent uses `compare_tax_regimes` to run side-by-side simulations of tax burdens. It is designed to work with your existing BigQuery data pipelines. You can feed massive datasets into the agent and get a clear picture of which regime saves the most cash. The math doesn't lie, and your agent will find the bottom line.

Deep dive into fiscal breakdowns

The `get_regime_breakdown` tool allows your agent to pull apart the components of your tax bill. It separates the PIS and COFINS from your corporate income taxes. This is useful when you need to justify an accounting shift to your CFO. You get the raw numbers for every line item in one simple request.

Cloud-native tax planning

This MCP fits into your Google Cloud environment without extra overhead. It exposes tools directly to your agent so you can build automated compliance monitoring. Your agents can now trigger fiscal analysis as part of your monthly closing process. It removes the manual work from your tax planning cycle.

Set up Tax Regime Comparator MCP in Google ADK

Prerequisites

Python 3.10+ installed
google-adk package (pip install google-adk)
Active Vinkius subscription with a valid endpoint token

1

Install Google ADK

Run pip install google-adk to install the Agent Development Kit. MCP support is included via the McpToolset class.
2

Connect via SSE transport

Use McpToolset.from_server() with SseServerParams pointing to your Vinkius endpoint. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
