Deterministic aggregation for OpenAI Agents SDK

The `aggregate_dataframe` tool forces your agent to compute sums and means locally instead of sending raw CSV strings to the model. This keeps your context window clear of repetitive data. Your OpenAI Agents SDK pipeline handles the tool execution directly. By processing massive files offline, you avoid the cost of redundant token usage while maintaining absolute accuracy.

Strict guardrails for data operations

When your agent triggers `aggregate_dataframe`, the SDK validates the operation before it hits the compute layer. This prevents your model from hallucinating math in your production system. Trace every calculation through your OpenAI dashboard to confirm the output matches your source files. You get a clean, validated result instead of an estimated guess from the model.

Production-ready local processing

Inject the DataFrame Aggregator Engine into your agent constructor to enable instant data pivot operations. The Python context manager ensures the connection stays alive only while you need it. Caching the tool list inside your SDK setup speeds up subsequent agent runs. Your system stays lean and responsive even when handling large-scale data imports.

Setup guide

Set up DataFrame Aggregator Engine 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 DataFrame Aggregator Engine tools at runtime.
3

Create your Agent

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

Run the agent

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

asyncio.run(main())

Common questions about DataFrame Aggregator Engine MCP in OpenAI Agents SDK

Process your CSVs locally with the tool before passing summaries to the model. This cuts your token bill significantly by removing the need to upload raw datasets.

Yes. The tool performs pivots and groupings on the server side, keeping your agent's memory footprint small. Only the final aggregated output reaches your model.

The tool returns exact, deterministic math. Since it operates on CSV strings offline, the results are mathematically perfect compared to model-generated calculations.

It is built for modern async Python. Use the provided context manager to manage the connection lifecycle within your agentic workflow.

Your raw CSV data stays in your local environment and never hits the model providers. This MCP server acts as a private, isolated compute node for your sensitive records.
