TestMu AI (Formerly LambdaTest) MCP Server

smithery badge ToolSDK MCP Registry

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

ToolWhat it does
HyperExecuteAI-native test orchestration. Generates HyperExecute YAML and test runner commands, triggers jobs, and reports status — no manual YAML authoring.
AutomationTriages test failures by pulling execution details, command logs, network logs, and console errors into one place for root-cause analysis.
SmartUIExplains visual regressions in plain English — pixel, layout, DOM, and perceptual differences, summarized rather than eyeballed.
AccessibilityRuns WCAG and a11y audits against hosted URLs or local React apps, returning violations with remediation guidance.
Test ManagerCovers 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": {
    "mcp-lambdatest": {
      "url": "https://mcp.lambdatest.com/mcp"
    }
  }
}

Claude Code

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

VS Code / GitHub Copilot

Add to your MCP configuration:

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

Cline

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

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

{
  "mcpServers": {
    "mcp-lambdatest": {
      "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.

Claude Desktop and other STDIO-only clients

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

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

Via Smithery

npm install -g smithery
smithery mcp add testmuai/testmu-mcp

Supported clients

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

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.
