Perplexity

Exact String Parsing

The `convert_from_roman` tool reads a Roman numeral string and outputs a standard integer. This stops your agent from guessing math during complex tasks. Your agent auto-discovers this capability over the MCP protocol. It handles standard subtractive logic instantly, so IX becomes 9 without triggering a failure.

OpenAI Agents SDK Formatting

The `convert_to_roman` tool takes an integer and generates the correct Roman numeral string. It requires a valid number between 1 and 3999. You connect this MCP Server using the MCPServerStreamableHttp class. Set cacheToolsList to True to cut down latency when your agent formats multiple numbers in a row.

Strict Regex Validation

The `convert_from_roman` and `convert_to_roman` tools enforce strict regex boundaries on every single input. They reject invalid character sequences and out-of-bounds numbers immediately. This deterministic behavior is exactly what a production MCP architecture needs. When an input fails, the OpenAI dashboard traces the exact validation error, letting your agent self-correct instead of proceeding with bad data.

Setup guide

Set up Deterministic Roman Numeral Converter 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 Deterministic Roman Numeral Converter tools at runtime.
3

Create your Agent

Pass the MCP to Agent(mcp_servers=[server]). The agent receives Deterministic Roman Numeral Converter tools as native definitions — JSON schemas resolve automatically.
4

Run the agent

Call Runner.run(agent, prompt) to execute. The agent invokes the appropriate Deterministic Roman Numeral Converter 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="Deterministic Roman Numeral Converter Agent",
            instructions="You have access to Deterministic Roman Numeral Converter tools.",
            mcp_servers=[server],
        )
        result = await Runner.run(agent, "List recent transactions")
        print(result.final_output)

asyncio.run(main())

Common questions about Deterministic Roman Numeral Converter MCP in OpenAI Agents SDK

Run pip install openai-agents. Initialize MCPServerStreamableHttp with your MCP endpoint URL and pass it to your agent's mcp_servers list.

The tool throws a strict validation error. Your OpenAI agent reads this explicit failure and can attempt to fix the input format.

No. The tools strictly enforce the standard range of 1 to 3999. Any integer outside this boundary triggers an immediate rejection.

LLMs struggle with character-level math. Offloading the conversion to deterministic MCP tools guarantees exact integer mapping every time.

Yes. The server only processes Roman numeral strings and integers. Execution happens inside a V8 Isolate Sandbox that destroys itself after the conversion finishes.
