How to Use the LoadNinja (Real-Browser Load Testing) MCP in OpenAI Agents SDK

Q: Can the OpenAI Agents SDK automatically stop runaway tests?

Yes, your agent can monitor active runs and execute stoptestrun if metrics exceed thresholds. This prevents runaway virtual user consumption from draining your account limits.

Q: How does LoadNinja (Real-Browser Load Testing) handle concurrency limits within the OpenAI Agents SDK?

The agent checks your active plan capacity by calling getaccount before starting any run. This step ensures you do not trigger tests that exceed your current virtual user limits.

Q: Can I select specific test locations and browsers dynamically?

Your agent can call listlocations and listbrowsers to find available testing nodes. It then configures the scenario runtime parameters dynamically based on what is active.

Run actual browser load tests and track virtual user metrics directly from your OpenAI Agents SDK pipelines.

Trigger Real-Browser Tests via this MCP Server

Your agent can kick off load tests without you writing custom execution scripts. By calling `run_scenario`, the agent spins up actual browser instances to mimic real user behavior on your site. You specify the virtual user count and duration, letting the agent handle the heavy lifting. If a test goes sideways or runs too long, the agent can step in immediately. It calls `stop_test_run` to kill the run and save your subscription limits. You don't have to watch the dashboard because your Python code handles the lifecycle automatically.

Audit Performance and Virtual User Limits

Stop guessing if your testing budget is about to blow up. This MCP Server lets your agent call `get_account` to check your actual subscription limits and active virtual user caps. It ensures you never trigger a massive test that gets blocked by your plan. Before starting a run, the agent executes `list_scenarios` to find the exact target. It matches your current deployment branch against configured test files, keeping your automated pipeline aligned with actual code changes.

Fetch Real-Time Performance Analytics

Raw performance data is where the real debugging happens. Your agent uses `get_test_run_stats` to extract raw latency and error data from completed runs. It parses the actual browser metrics instead of relying on basic protocol-level pings. To track overall execution trends, the agent can call `list_test_runs` or pull details via `get_test_run`. This lets you feed actual performance numbers directly into your OpenAI tracing dashboard for historical analysis.

Setup guide

Set up LoadNinja (Real-Browser Load Testing) 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 LoadNinja (Real-Browser Load Testing) tools at runtime.
3

Create your Agent

Pass the MCP to Agent(mcp_servers=[server]). The agent receives LoadNinja (Real-Browser Load Testing) tools as native definitions — JSON schemas resolve automatically.
4

Run the agent

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

asyncio.run(main())

Common questions about LoadNinja (Real-Browser Load Testing) MCP in OpenAI Agents SDK

Install the agent package and configure the HTTP server stream. You pass the server parameters to your Agent constructor using the MCP server list. The agent automatically discovers tools like `run_scenario` with zero extra configuration.

Yes, your agent can monitor active runs and execute `stop_test_run` if metrics exceed thresholds. This prevents runaway virtual user consumption from draining your account limits.

The agent checks your active plan capacity by calling `get_account` before starting any run. This step ensures you do not trigger tests that exceed your current virtual user limits.

Your agent can call `list_locations` and `list_browsers` to find available testing nodes. It then configures the scenario runtime parameters dynamically based on what is active.

This MCP Server only accesses your LoadNinja test scenarios, run statistics, and account limits. All traffic runs through ephemeral, zero-trust V8 isolates on Vinkius, meaning your API tokens and raw performance metrics are never persisted or exposed to outside parties.
