Run the numbers with OpenAI Agents SDK

This MCP gives your agent the ability to execute `calculate_cd_yield` directly from a Python script. You pass the term length and compounding frequency. The agent returns concrete yield figures instead of guessing at interest math. Let that sink in. Built-in guardrails mean your agent validates the inputs before running the calculation. You do not have to worry about a hallucinated decimal point wiping out an entire financial projection. The math doesn't lie.

Compare yields against actual benchmarks

You can pull current liquid alternative rates using `fetch_market_benchmarks` to see if locking up cash makes sense. The system retrieves hardcoded high-yield savings and money market figures based on current interest levels. Look, idle cash loses to inflation. Handoffs between specialized agents work perfectly here. One agent fetches the benchmark data. Another agent reviews the rates and decides if the yield spread justifies the liquidity lockup.

Generate side-by-side investment scenarios

Your agent triggers `generate_investment_comparison` through this MCP to put the certificate of deposit head-to-head with market alternatives. It builds a high-level projection showing exactly how much money sits in each bucket at maturity. Tracing via the OpenAI dashboard lets you watch every step of this comparison process. You see the exact inputs and outputs for every financial scenario. Bottom line: you get transparency.

Setup guide

Set up CD 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 CD Return Calculator tools at runtime.
3

Create your Agent

Pass the MCP to Agent(mcp_servers=[server]). The agent receives CD 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 CD 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="CD Return Calculator Agent",
            instructions="You have access to CD Return Calculator tools.",
            mcp_servers=[server],
        )
        result = await Runner.run(agent, "List recent transactions")
        print(result.final_output)

asyncio.run(main())

Common questions about CD Return Calculator MCP in OpenAI Agents SDK

Install the package via pip install openai-agents. Create a streamable HTTP connection with your Vinkius URL. Pass it to the agent constructor in your Python file.

Yes. Every calculation your agent performs shows up in the dashboard. You can audit the exact numbers used for yield projections.

Set cacheToolsList to true when configuring the MCP. This stops the agent from pulling the schema on every single request. It speeds up the financial modeling significantly.

Yes, handoffs are native to this framework. A math agent can compute the yields and pass the results to a summary agent for client reporting.

The system only processes term lengths, interest rates, and deposit amounts. Your Vinkius connection runs through secure HTTPS streams. We do not store your principal investment balances after the calculation finishes.
