How to Use the Depreciation Calculator MCP in OpenAI Agents SDK

Q: How does the Depreciation Calculator work with the OpenAI Agents SDK?

You pass the MCP server URL to the MCPServerStreamableHttp class when creating your agent. The SDK automatically discovers the calculation tools, making them available to your agent without any manual mapping.

Q: Can I cache the tools from this MCP for better performance?

Yes. Set cacheToolsList=True in the SDK's server parameters. This prevents the agent from re-fetching the tool list on every startup, which is ideal for production environments.

Get accurate, auditable asset depreciation calculations inside your production agents using the OpenAI Agents SDK.

Run Standard Depreciation Models

This MCP gives your agent the three most common depreciation methods. It handles the math, so your agent can focus on higher-level financial analysis. No need to code these formulas from scratch in Python. Your agent can call `calculate_straight_line` for simple, consistent depreciation. For accelerated schedules, it can use `calculate_sum_of_years_digits` or `calculate_declining_balance` depending on the asset type and accounting rules.

Built for Production OpenAI Agents

The OpenAI Agents SDK automatically discovers these tools. You just point it at the MCP URL and your agents are ready to calculate depreciation. The built-in guardrails ensure the agent provides valid inputs before executing the calculation. This is perfect for building multi-agent systems. One agent can fetch asset data from a database, then hand off to a specialized "finance agent" that uses this Depreciation Calculator MCP to run the numbers. Everything is traceable in your OpenAI dashboard.

Focus on Financial Logic, Not Math

Stop worrying about floating-point errors or misimplementing a financial formula. This provides a tested, reliable source for depreciation math. It's a single point of truth for your financial agents. By offloading the calculations, your agent's core logic becomes simpler and easier to maintain. You can focus on the business rules, like when to apply a certain depreciation method, instead of the raw number crunching.

Setup guide

Set up Depreciation 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 Depreciation Calculator tools at runtime.
3

Create your Agent

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

asyncio.run(main())

Yes. Set `cacheToolsList=True` in the SDK's server parameters. This prevents the agent from re-fetching the tool list on every startup, which is ideal for production environments.

This MCP supports straight-line, sum-of-the-years' digits, and declining balance methods. Your agent can call the specific tool it needs based on the asset and accounting context.

It's built for production. The OpenAI Agents SDK's guardrails and tracing, combined with a managed MCP, give you a reliable way to add financial calculations to a deployed agent system.

It only receives the inputs for a single calculation: asset cost, salvage value, useful life, and the specific period. No other company or user data is sent to or stored by this MCP. All connections are over TLS for security.
