How to Use the VAT Tax Validator MCP in Google ADK

Q: How does the VAT Tax Validator integrate with Google ADK?

You expose the validatevat tool using the McpToolset within your agent setup. This allows your Gemini-powered agents to access the validation logic directly when running on Google Cloud infrastructure.

Q: What is the best way to handle VAT checks in a large dataset?

Running validatevat through the Google ADK lets you process structured data in BigQuery. You can map your columns of tax IDs and run the validation check across millions of records efficiently.

Run accurate B2B VAT Tax Validator checks within your Google ADK BigQuery pipelines.

Validate tax numbers with `validate_vat`

The `validate_vat` tool allows you to execute offline mathematical validation against European and global VAT numbers. This function confirms if a submitted tax ID matches its country's required format. Because it’s available through the Google ADK, you can seamlessly call this check while processing large datasets already residing in BigQuery.

Check compliance during data ETL processes

You can build steps into your agent that verify tax IDs before they enter a final table. This prevents bad or non-compliant records from ever reaching your production data warehouse. This is critical for enterprise reporting, making sure every transaction record starts with clean, validated financial metadata.

Integrate validation into long-context reasoning

When using Gemini models with the Google ADK, you can make tax compliance a core part of complex decision logic. The agent uses `validate_vat` to confirm prerequisites before generating reports or initiating workflows. It grounds your LLM's output in verifiable, structured business rules.

Setup guide

Set up VAT Tax Validator 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 VAT Tax Validator 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="VAT Tax Validator_agent",
    model="gemini-2.0-flash",
    instruction="You have access to VAT Tax Validator tools via MCP.",
    tools=mcp_tools,
)
