How to Use the Bond Yield Calculator MCP in Google ADK

Q: How do I restrict my agent to only use specific calculator functions?

Use the toolnames filter when setting up the toolset. This ensures your agent only executes the exact math operations you authorize.

Run the Bond Yield Calculator through Google ADK to process fixed-income data directly.

BigQuery Yield Processing

The `get_bond_yield_metrics` tool lets your agent pull raw BigQuery data and compute Yield to Maturity instantly. Your enterprise stores massive amounts of pricing data in the cloud. You skip the middleman and run the math right where your data lives. The agent reads the bond characteristics from your tables and feeds them into the calculator. It returns exact figures for current yield and interest rate sensitivity. You get institutional-grade fixed-income math applied across thousands of CUSIPs without writing custom SQL functions.

Long-Context Market Analysis

Gemini models hold millions of tokens. You can feed an agent an entire quarter of bond market history. When the system spots a pricing anomaly, it hits this MCP to verify the math. The calculator acts as a reality check against the massive context window. Language models read text well but fail at calculating Macaulay Duration. This setup gives you the best of both worlds. The agent reads the macro environment, and the calculator handles the deterministic math.

Google ADK Infrastructure

Running agents on Google Cloud requires strict architectural standards. You connect to Vinkius once using the standard toolset class. The framework handles the HTTP transports automatically so you don't waste time on boilerplate code. You can restrict the exposed tools using filters if you want tight control. Your Vertex AI agents get immediate access to reliable bond math without deploying custom microservices. It just works.

Setup guide

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

Common questions about Bond Yield Calculator MCP in Google ADK

Install the google-adk package via pip. Initialize an McpToolset with your Vinkius URL parameters and pass that toolset to your LlmAgent configuration.

Yes. Your agent can query BigQuery for bond prices and immediately pass those values to the MCP. The resulting yield metrics can then be written back to your database.

The agent iterates through your records and calls the calculator for each bond. The long-context window allows the agent to process large batches of pricing data in a single session.

Use the tool_names filter when setting up the toolset. This ensures your agent only executes the exact math operations you authorize.

The MCP only sees isolated numeric variables like maturity dates and coupon rates. Vinkius routes these anonymous variables through secure cloud endpoints. We do not store your bond inputs or the resulting yield calculations.
