Common questions

Is TestMu AI (formerly LambdaTest) safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.7) reached the registry 17 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

TestMu AI (Formerly LambdaTest) MCP Server

Run, debug, and triage tests using natural language, directly from your IDE.

The TestMu AI MCP Server connects any MCP-compatible client to the TestMu AI (Formerly LambdaTest) platform — so you can orchestrate test runs, debug failures, analyze visual regressions, and run accessibility audits without leaving your editor or switching between dashboards.

This repository is the setup guide and reference for the hosted MCP server. The server itself runs as a managed service at https://mcp.lambdatest.com/mcp — there is nothing to install or self-host.

Tools

Tool	What it does
HyperExecute	AI-native test orchestration. Generates HyperExecute YAML and test runner commands, triggers jobs, and reports status — no manual YAML authoring.
Automation	Triages test failures by pulling execution details, command logs, network logs, and console errors into one place for root-cause analysis.
SmartUI	Explains visual regressions in plain English — pixel, layout, DOM, and perceptual differences, summarized rather than eyeballed.
Accessibility	Runs WCAG and a11y audits against hosted URLs or local React apps, returning violations with remediation guidance.
Test Manager	Covers the test management lifecycle — AI test case generation through to bulk result recording.

Prerequisites

A TestMu AI account
An MCP-compatible client (see below)
Node.js 18+ — only if your client needs the STDIO fallback

Authentication is handled over OAuth. On first connection, your client opens a browser window to authorize against testmuai.com; no API keys need to be stored in config files.

Setup

The server endpoint is:

https://mcp.lambdatest.com/mcp

Cursor

Add to ~/.cursor/mcp.json (global) or .cursor/mcp.json (per project):

"mcpServers": { "testmu-ai": { "url": "https://mcp.lambdatest.com/mcp" } } }

Claude Code

claude mcp add --transport http testmu-ai https://mcp.lambdatest.com/mcp

Or install from the TestMu AI plugin marketplace (Claude Code v2.1.292 or later):

claude plugin install kane-cli --marketplace LambdaTest/mcp-server-guide

claude plugin install rook --marketplace LambdaTest/mcp-server-guide claude plugin install testmu-ai --marketplace LambdaTest/mcp-server-guide

Plugin	What you get
`kane-cli`	Kane CLI skill for browser automation, mobile app testing and AI test authoring
`rook`	Rook inside Claude Code for testing the AI agents you build
`testmu-ai`	This MCP server plus the Kane CLI and Rook CLI skills

On older versions, add the marketplace first with claude plugin marketplace add LambdaTest/mcp-server-guide, then run claude plugin install kane-cli@testmu-ai. Inside a Claude Code session, use /plugin marketplace add LambdaTest/mcp-server-guide and /plugin install kane-cli@testmu-ai.

VS Code / GitHub Copilot

Add to your MCP configuration:

"servers": { "testmu-ai": { "type": "http", "url": "https://mcp.lambdatest.com/mcp" } } }

Cline

Open the Cline panel, click the MCP Servers icon, then Configure > Remote Servers:

Server Name: testmu-ai
Server URL: https://mcp.lambdatest.com/mcp
Transport Type: Streamable HTTP

Or click Configure MCP Servers in Cline to open cline_mcp_settings.json and add:

"mcpServers": { "testmu-ai": { "type": "streamableHttp", "url": "https://mcp.lambdatest.com/mcp" } } }

There is nothing to clone or install. Click Authenticate when it appears to complete the OAuth sign-in.

OpenCode

Add to ~/.config/opencode/opencode.json (global) or opencode.json in your project root:

"$schema": "https://opencode.ai/config.json", "mcp": { "testmu-ai": { "type": "remote", "url": "https://mcp.lambdatest.com/mcp", "oauth": {} } } }

Then run opencode mcp auth testmu-ai to sign in through your browser. opencode mcp list should show testmu-ai connected.

Kilo Code

Add to ~/.config/kilo/kilo.jsonc:

"$schema": "https://app.kilo.ai/config.json", "mcp": { "testmu-ai": { "type": "remote", "url": "https://mcp.lambdatest.com/mcp" } } }

Then open Kilo Settings > Agent Behaviour > MCP Servers and click Sign in next to testmu-ai.

Claude Desktop and other STDIO-only clients

Clients that don't yet support remote HTTP transport can connect through mcp-remote:

"mcpServers": { "testmu-ai": { "command": "npx", "args": ["-y", "mcp-remote@latest", "https://mcp.lambdatest.com/mcp"] } } }

Supported clients

Cursor · Claude Code · Claude Desktop · GitHub Copilot · OpenAI Codex · Windsurf · Cline · Continue · Zed AI · JetBrains AI Assistant · Antigravity · OpenCode · Kilo Code

Any client implementing the Model Context Protocol should work. Clients with native remote HTTP support connect directly; the rest use the mcp-remote fallback above.

Example prompts

Once connected, ask your assistant things like:

Generate a HyperExecute YAML for my Playwright TypeScript tests and run it.

My last automation build failed — pull the console and network logs and tell me why.

Summarise the SmartUI visual differences in my latest build.

Run an accessibility audit on https://staging.example.com and list WCAG violations by severity.

Troubleshooting

Server doesn't appear after editing config Fully quit and reopen the client. Reloading the window is not enough for most clients to re-read MCP configuration.

Config not being picked up Validate the JSON. A trailing comma or mismatched brace will cause the client to silently skip the entry.

`npx` not found (STDIO fallback) Confirm Node.js is on your PATH — which npx on macOS/Linux, where npx on Windows. Some clients don't inherit your shell environment, so an absolute path to npx may be needed.

Authentication loop or expired session Clear the stored authentication for this server in your client's MCP settings and reconnect to re-trigger the OAuth flow.
