Perplexity

Record live experiment traces

Use `create_experiment` to log every step of your agent execution path. This captures exactly how your production pipeline performs under load. Your OpenAI Agents SDK instances push these logs to Braintrust immediately. You get an audit trail of every decision your agent makes during testing.

Manage prompt versions for OpenAI Agents SDK

Call `get_prompt` to pull the latest system instructions stored in your Braintrust account. You stop hardcoding strings in your Python files. Updating a prompt in the Braintrust dashboard reflects in your agent behavior instantly. It keeps your logic isolated from your deployment code.

Automate dataset testing

Run `insert_dataset_row` to feed agent outputs back into your evaluation matrix. You build a feedback loop that validates your agent against real data. This MCP server handles the handshake between your SDK and the Braintrust database. You focus on building the agent logic while the infrastructure tracks the accuracy.

Setup guide

Set up Braintrust 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 Braintrust tools at runtime.
3

Create your Agent

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

Run the agent

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

asyncio.run(main())
