Perplexity

Bring deterministic math to Google ADK enterprise agents

The `calculate_amortization` tool delivers accurate SAC or PRICE schedules directly into your Google ADK agent's context window. Enterprise agents running on Google Cloud need to process massive amounts of data without making calculation errors. Whether the client uses SAC or PRICE amortization, `calculate_amortization` handles it natively. The tool returns clean, structured data that Gemini can immediately interpret.

Analyze long-term interest trends at scale

The `calculate_compound_interest` tool provides exact future value figures for any principal and rate combination. Gemini's massive token capacity allows your agent to analyze decades of financial history in a single run, but projecting interest still requires exact formulas. Your agent runs `calculate_compound_interest` to get exact future value figures. This lets your enterprise assistant generate deep, data-driven financial reports for your cloud-hosted databases.

Deploy secure financial tools on Google Cloud

This MCP Server runs in a secure, isolated sandbox, making it perfect for Google ADK enterprise deployments. You can restrict which tools are visible to your agent using the toolset filter in your Python setup. The connection supports both standard input-output and HTTP transports, aligning with your existing Google Cloud infrastructure. You get reliable, zero-trust math execution for `calculate_amortization` without modifying your core networking rules.

Setup guide

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

Common questions about Financial Math Engine MCP in Google ADK

Initialize the toolset using the streamable HTTP parameters pointing to your Vinkius hosted endpoint. Pass the toolset object directly into your LlmAgent configuration to expose the tools.

Yes. You can use the optional tool names filter when initializing your toolset to expose only `calculate_amortization` or `calculate_compound_interest` depending on your agent's scope.

Even long-context models struggle with multi-period compound interest and amortization tables. This MCP Server guarantees zero-hallucination math, freeing Gemini to focus on high-level analysis of the results.

Yes. Your agent can read raw financial rows from BigQuery, pass the values to the math tools, and write the structured amortization schedules back to your database.

This MCP Server runs all calculations inside a zero-trust, ephemeral environment. Your principal values, interest rates, and loan terms are processed in-memory and destroyed immediately after the calculation is returned, ensuring no data leaks into external training sets.
