BigQuery Financial Integration

This MCP exposes the `compare_business_structures` tool so your Google Cloud agents can evaluate pass-through versus double taxation burdens. You can pipe millions of rows of historical company revenue from BigQuery directly into the context window for massive batch analysis. Long-context reasoning shines when evaluating complex corporate hierarchies. The agent holds entire financial histories in memory while testing different entity types against the current tax brackets.

State Tax Rate MCP Server Lookups

Your AI client executes the `get_state_tax_rate` tool to pull fixed corporate income percentages across all 50 states. Hardcoded dictionaries prevent the agent from hallucinating outdated regional tax codes during analysis. You can restrict which regions the agent queries by using the optional tool names filter during setup. This keeps execution focused when your enterprise only operates in specific geographic zones.

Exact Liability Computations

Enterprise agents use the `calculate_tax_liability` tool to compute precise federal and state breakdowns for a single profit amount. The integration applies the standard flat federal rate alongside local obligations to find the true bottom line. Accessing the Vinkius catalog takes one connection. Your Gemini models immediately gain the ability to process these exact mathematical operations instead of approximating math through token prediction.

Setup guide

Set up US Corporate 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 US Corporate 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="US Corporate Tax Calculator_agent",
    model="gemini-2.0-flash",
    instruction="You have access to US Corporate Tax Calculator tools via MCP.",
    tools=mcp_tools,
)

Common questions about US Corporate Tax Calculator MCP in Google ADK

Install the framework and initialize an McpToolset with StreamableHttpServerParameters pointing to your endpoint. Pass that toolset to your LlmAgent to expose the capabilities.

The integration processes numbers you send it. Your agent must first query BigQuery to extract the relevant profit figures before passing those values into the tax tools.

Calculations rely on single-state residency. Multi-jurisdiction income allocation falls outside the current scope of these tools.

No. Base liability computations ignore specialized credits and focus strictly on standard corporate tax rates.

Profit figures and business structure preferences remain in memory during execution. Vinkius discards the computational payload immediately after returning the tax breakdown to your Google Cloud environment.
