About TestMu AI (formerly LambdaTest) MCP Server
Connect your TestMu AI (formerly LambdaTest) account to any AI agent and take full control of your cross-browser testing and automation orchestration through natural conversation.
LangChain's ecosystem of 500+ components combines seamlessly with TestMu AI (formerly LambdaTest) through native MCP adapters. Connect 10 tools via Vinkius and use ReAct agents, Plan-and-Execute strategies, or custom agent architectures. with LangSmith tracing giving full visibility into every tool call, latency, and token cost.
What you can do
- Build Orchestration — List all test automation builds and retrieve high-level aggregated telemetry for Selenium, Playwright, or Cypress suites directly from your agent
- Session Inspection — Deep-dive into individual browser test sessions to extract console errors, network configurations, and exact metadata required for rapid debugging
- Visual Artifacts — Fetch absolute URLs for bug screenshots and full video recordings of browser executions to reproduce flakey UI issues instantly
- Precision Logging — Extract command-level logs including W3C WebDriver protocols or Playwright RPC calls with precise execution timestamps
- Tunnel & Platform Audit — Monitor active secure tunnels for localhost testing and query the grid for supported macOS, Windows, iOS, and Android capabilities
- Environment Mapping — Filter and retrieve all child test sessions nested under specific CI/CD builds to isolate and analyze deployment regressions
The TestMu AI (formerly LambdaTest) MCP Server exposes 10 tools through the Vinkius. Connect it to LangChain in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.
