How to Use the LambdaTest MCP in OpenAI Agents SDK

Q: How do I connect LambdaTest to the OpenAI Agents SDK?

Use the MCPServerStreamableHttp class with your endpoint URL. Pass it to the mcpservers array in your Agent constructor. Set cacheToolsList=True so the agent discovers the testing tools instantly on startup.

Q: Can the OpenAI agent mark a LambdaTest session as passed?

Yes. It calls the updatesessionstatus tool to change the outcome. You should enforce an execution guardrail in the SDK if you want a human to review the decision first.

Q: Why is my OpenAI agent failing to read LambdaTest logs?

The gettestlogs tool might be returning a payload larger than your current context window limits. Check your OpenAI tracing dashboard to see if the tool execution timed out or if the model truncated the response.

Q: Does this setup support handoffs between specialized QA agents?

Absolutely. You can have one agent monitor listautomationbuilds for failures. When it finds one, it hands the session ID to a debugging agent that runs gettestlogs.

OpenAI Agents SDK MCP Server Integration

The `list_automation_builds` and `get_build_details` tools let your OpenAI agent pull CI pipeline outcomes directly into its context window. You don't need to write custom API wrappers to track down why the nightly run failed. The agent auto-discovers this MCP Server and starts reading build statuses immediately. Once it finds a broken build, the agent uses `list_test_sessions` to isolate the exact run. Because you're using OpenAI's built-in guardrails, you can restrict the agent from taking destructive actions while it analyzes the test matrix. It just reads the data, hands off the findings to a specialized debugging agent, and logs the entire trace in your OpenAI dashboard.

Log Analysis & Debugging

Fetching execution output happens through the `get_test_logs` and `get_session_details` tools. Your agent pulls the raw console output from the cloud browser session. If a test flakes out on a specific Chrome version, the agent has the exact stack trace ready for analysis. It then cross-references that failure against `list_supported_platforms` to see if the target environment is actually valid. You skip the manual step of digging through the LambdaTest web UI. The agent reads the logs, identifies the DOM timeout, and writes a summary for your engineering team.

Automated Status Updates

The `update_session_status` tool gives your agent write access to mark test outcomes as passed or failed. This is where autonomous QA actually happens. The agent evaluates the visual regression diff or the network logs, decides if the failure is a false positive, and updates the LambdaTest dashboard directly. You configure the OpenAI SDK to require a human-in-the-loop approval before this tool executes. That keeps your metrics accurate without slowing down the initial triage. The agent does the heavy lifting, you hit approve, and the pipeline keeps moving.

Setup guide

Set up LambdaTest 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 LambdaTest tools at runtime.
3

Create your Agent

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

Run the agent

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

asyncio.run(main())
