Compute cumulative tax rates using this MCP Server

The `calculate_cumulative_tax` tool calculates your exact PIS and COFINS liabilities under the basic cumulative regime. This is the default path for many service companies. By linking this MCP to your Google ADK agent, you can pull revenue records directly from BigQuery. The agent computes the tax in seconds, keeping your financial reports accurate.

Audit non-cumulative credits in Google ADK

The `calculate_non_cumulative_tax` tool determines your net tax liabilities by offsetting eligible input credits. Look, here's the kicker. Most multinationals miss millions in deductible credits because their tracking is broken. Your agent can analyze complex supply chain invoices to find valid deductions. It applies the correct 1.65 percent PIS and 7.6 percent COFINS rates to ensure full compliance.

Compare tax regimes automatically

The `evaluate_regime_comparison` tool compares both Brazilian tax regimes based on your actual operational costs. Run the numbers first. Let that sink in before you commit to a fiscal year strategy. Your agent can run this evaluation across massive historical datasets in Google Cloud. This MCP provides the raw analytical power your CFO needs to make a clear, data-backed recommendation on which regime minimizes cash leakage.

Setup guide

Set up PIS/COFINS Tax Calculator 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.
3

Create an LlmAgent

Pass the returned mcp_tools list directly to LlmAgent(tools=mcp_tools). The ADK maps each MCP tool to a native Gemini function call — no manual schema definitions required.
4

Run with any Gemini model

The agent works with any Gemini model (gemini-2.0-flash, gemini-2.5-pro, etc.). Copy the full example on the right to get started with PIS/COFINS Tax Calculator tools in your ADK agent.

agent.py

from google.adk.agents import LlmAgent
from google.adk.tools.mcp_tool.mcp_toolset import McpToolset
from google.adk.tools.mcp_tool.mcp_session_manager import SseServerParams

# Connect to the MCP via SSE
mcp_tools, exit_stack = await McpToolset.from_server(
    connection_params=SseServerParams(
        url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    )
)

# Create your agent with auto-discovered tools
agent = LlmAgent(
    name="PIS/COFINS Tax Calculator_agent",
    model="gemini-2.0-flash",
    instruction="You have access to PIS/COFINS Tax Calculator tools via MCP.",
    tools=mcp_tools,
