How to Use the Currency Math Engine MCP in Google ADK

Q: How do I install Currency Math Engine for Google ADK?

Run pip install google-adk and configure a McpToolset using the HTTP transport. Pass that toolset array to your LlmAgent initialization.

Give your Google ADK enterprise agents exact integer math capabilities to stop Gemini from hallucinating invoice totals.

Perplexity

Flawless BigQuery Financials via MCP Server

The `calculate_currency` tool forces your Gemini models to stop guessing decimal placements. Enterprise agents pulling massive datasets from BigQuery often stumble when asked to aggregate complex cart totals using native model reasoning. Passing the raw numbers to this external engine guarantees strict integer-based mathematics. Your agent gets a precise, non-hallucinated result back to inject straight into your Google Cloud infrastructure.

Process 1M+ Token Contexts Accurately

Feeding thousands of receipts into Gemini's massive context window is incredibly powerful until the model tries to sum the taxes. Generative math breaks down at scale. Delegating the arithmetic to a specialized tool eliminates that failure point. The model extracts the values from the long context and lets the deterministic engine handle the actual addition and division.

Simple Google Cloud Integration

Setting up the connection requires passing your Vinkius endpoint to `StreamableHttpServerParameters`. You then wrap it in a `McpToolset` and hand it directly to your `LlmAgent`. Filtering exposed tools is easy if you only want specific agents to access the math functions. You can restrict the toolset so only your billing agent performs the final invoice formatting.

Setup guide

Set up Currency Math Engine 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 Currency Math Engine 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="Currency Math Engine_agent",
    model="gemini-2.0-flash",
    instruction="You have access to Currency Math Engine tools via MCP.",
    tools=mcp_tools,
)

Common questions about Currency Math Engine MCP in Google ADK

Run `pip install google-adk` and configure a `McpToolset` using the HTTP transport. Pass that toolset array to your `LlmAgent` initialization.

Writing and maintaining custom math tools for every agent takes time. This MCP Server provides an instant, tested integer math engine that prevents floating-point errors out of the box.

Yes, any model supported by the framework can call these tools. Gemini excels at extracting the numbers from your BigQuery data and passing them to the engine for exact calculation.

The framework supports both Stdio and HTTP transports. You will use the `StreamableHttpServerParameters` class to connect to the managed Vinkius endpoint.

The engine receives only the numeric values and the requested operation. Every request executes inside an ephemeral zero-trust sandbox that drops all state the millisecond your math result returns.
