Automate build reporting in LangChain chains

Feed the output of `list_automation_builds` directly into your agent logic to determine which pipelines require investigation. You can chain this with other data sources to correlate test failures with recent code commits. Your agent parses the build status automatically. It decides if a build needs a deeper look using `get_build_details` without you writing custom glue code.

Programmatic test session management

Trigger `list_test_sessions` to pull active runs into your LangChain memory. The agent tracks specific build IDs to isolate problematic sessions in real-time. Once the agent identifies a failure, it uses `update_session_status` to mark the test outcome. This keeps your CI/CD pipeline synchronized with actual test results.

Deep dive into execution logs

Retrieve raw data using `get_test_logs` to diagnose why a browser instance failed. The agent reads the logs and summarizes the error stack for you. This MCP Server provides the raw context your agent needs. It turns unstructured test output into clear, actionable insights for your engineering team.

Setup guide

Set up LambdaTest MCP in LangChain

Prerequisites

Python 3.10+ installed
langchain-mcp-adapters + langgraph packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run pip install langchain-mcp-adapters langgraph langchain-openai. The MCP adapters package converts MCP tools into native LangChain BaseTool objects.
2

Connect via HTTP transport
Use MultiServerMCPClient with "transport": "http" pointing to your Vinkius endpoint. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Create a ReAct agent
Pass the discovered tools to create_react_agent() from LangGraph. The agent automatically routes LambdaTest tool calls through the MCP protocol.
4

Run with any LLM
Swap ChatOpenAI for ChatAnthropic, ChatGoogleGenerativeAI, or any LangChain-compatible model. The MCP tools work identically across all providers.

agent.py

from langchain_mcp_adapters.client import MultiServerMCPClient
from langgraph.prebuilt import create_react_agent
from langchain_openai import ChatOpenAI

async with MultiServerMCPClient({
    "lambdatest-mcp": {
        "transport": "http",
        "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp",
    }
}) as client:
    tools = client.get_tools()

    agent = create_react_agent(
        ChatOpenAI(model="gpt-4o"),
        tools,
    )
    result = await agent.ainvoke({
        "messages": "List recent LambdaTest transactions"
    })
    print(result["messages"][-1].content)
