How to Use the Treasury Return Calculator MCP in OpenAI Agents SDK

Q: How does the Treasury Return Calculator handle performance inside OpenAI Agents SDK?

Enable the cacheToolsList=True flag during initialization. This prevents the SDK from querying the MCP on every single agent turn. It keeps latency low during high-frequency financial calculations.

Get instant sovereign bond pricing and inflation adjustments in your OpenAI Agents SDK production workflows.

Pricing Gilts and Bunds with OpenAI Agents SDK

The `calculate_bond_valuation` tool calculates fair market price and annualized yield to maturity for sovereign debt. Your production agents get real-time valuation capabilities without hardcoding financial math. This MCP lets your agents run multi-step bond analysis while staying within your defined security parameters. They can inspect yields, compare historic prices, and execute financial decisions safely.

Cross-Currency Yield Math

We use `calculate_currency_equivalent_yield` to normalize returns across different currencies like USD, GBP, and EUR. This tool translates international yields into a single target currency so your agents compare apples to apples. You can route these conversions through specialized agents using the SDK's native handoff features. The system tracks every conversion step on your dashboard, keeping your cross-border portfolios transparent.

Inflation-Adjusted Returns

The `calculate_inflation_adjusted_return` tool applies the Fisher equation to strip out inflation from nominal yields. It's the tool that tells your agent exactly how much purchasing power a bond actually preserves. Built-in guardrails validate these calculations before your agents commit to a strategy. You get predictable, inflation-adjusted analysis without risking runtime logic failures.

Setup guide

Set up Treasury Return Calculator MCP in OpenAI Agents SDK

Prerequisites

Python 3.10+ installed
openai-agents package (pip install openai-agents)
Active Vinkius subscription with a valid endpoint token

1

Install the SDK

Run pip install openai-agents to install the OpenAI Agents SDK. The MCP integration is built-in — no extra dependencies needed.
2

Connect via SSE transport

Use MCPServerSse with your Vinkius endpoint URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. The SDK auto-discovers all Treasury Return Calculator tools at runtime.
3

Create your Agent

Pass the MCP to Agent(mcp_servers=[server]). The agent receives Treasury Return Calculator tools as native definitions — JSON schemas resolve automatically.
4

Run the agent

Call Runner.run(agent, prompt) to execute. The agent invokes the appropriate Treasury Return Calculator tools and returns structured results. Copy the full example on the right to get started.

agent.py

import asyncio
from agents import Agent, Runner
from agents.mcp import MCPServerSse

async def main():
    async with MCPServerSse(
        url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    ) as server:
        agent = Agent(
            name="Treasury Return Calculator Agent",
            instructions="You have access to Treasury Return Calculator tools.",
            mcp_servers=[server],
        )
        result = await Runner.run(agent, "List recent transactions")
        print(result.final_output)

asyncio.run(main())

Common questions about Treasury Return Calculator MCP in OpenAI Agents SDK

Install the package via pip first. Next, spin up the MCP using the `MCPServerStreamableHttp` constructor with your endpoint URL. Finally, pass that instance into your agent's constructor to auto-discover all tools.

Yes, you can control tool access directly in your agent configuration. The SDK allows you to filter discovered tools or set up specialized agent handoffs. This ensures sensitive valuation tools only run when explicitly authorized.

Enable the `cacheToolsList=True` flag during initialization. This prevents the SDK from querying the MCP on every single agent turn. It keeps latency low during high-frequency financial calculations.

The MCP returns a structured error to the agent. The SDK's built-in guardrails catch these validation errors before they propagate. Your agent can then ask for corrected inputs or gracefully halt the run.

Your bond yield inputs, purchase prices, and inflation rates stay completely within your private network. The MCP operates locally or via secure HTTP, meaning your proprietary portfolio details never leak to public logs. OpenAI only receives the verified mathematical outputs needed for the run.
