How to Use the Deterministic Base Converter MCP in OpenAI Agents SDK

Q: What data does this server see when my agent uses it?

The server only processes the numeric strings, 'frombase', and 'tobase' values you send for conversion. All operations are performed in an ephemeral, zero-trust sandbox and are not logged or stored.

Give your OpenAI Agent perfect, infinite-precision math for any number base. Stop silent calculation errors in production.

Perplexity

Guaranteed Correct Conversions

The `convert_base` tool gives your agent a way to translate numbers between any base from 2 to 36. LLMs are notoriously bad at character-level math, but this tool uses BigInt precision so the answer is always right. Your OpenAI Agent auto-discovers these tools with zero configuration. You can then use the SDK's guardrails to validate that it's only calling `convert_base` for appropriate tasks, and trace every conversion directly in the OpenAI dashboard.

Optimized for Dev Workflows

This server includes dedicated tools for common developer jobs, like `convert_bin_to_dec` and `convert_hex_to_dec`. Your agent can now correctly parse raw binary data, network packet headers, or cryptographic keys without guessing. When you're building specialized agents that hand off tasks, one agent can focus on low-level data parsing using these tools. The OpenAI Agents SDK makes this handoff clean, ensuring the right agent handles the right job with guaranteed mathematical accuracy.

A Reliable MCP Server

This isn't just a script; it's a managed Vinkius MCP server. It runs in a secure sandbox, handles authentication for you, and guarantees calculations are completed, not just attempted. For your agent, this means tool calls are fast and dependable. Just set `cacheToolsList=True` in your `MCPServerStreamableHttp` configuration. Your agent won't even need to refetch the tool list on subsequent runs, making it even faster.

Setup guide

Set up Deterministic Base 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 Base Converter tools at runtime.
3

Create your Agent

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

asyncio.run(main())

Common questions about Deterministic Base Converter MCP in OpenAI Agents SDK

You add the server's endpoint to your Agent's configuration. The SDK handles tool discovery automatically, so your agent can immediately start calling `convert_base`, `convert_bin_to_dec`, and `convert_hex_to_dec`.

Many production environments restrict arbitrary code execution for security. This MCP server provides a sandboxed, deterministic alternative that's always available and always correct, without opening up security holes.

Yes. All conversions are handled with BigInt precision and complete well under 100 milliseconds. It's built for production systems where your agent needs immediate, accurate results.

Precision. Your agent stops guessing at math and gets verifiable, correct answers for any number conversion. This eliminates a whole class of silent bugs related to data parsing and low-level data manipulation.

The server only processes the numeric strings, 'from_base', and 'to_base' values you send for conversion. All operations are performed in an ephemeral, zero-trust sandbox and are not logged or stored.
