The server itself runs as a managed service at `https://mcp.lambdatest.com/mcp` — there is nothing to install or self-host.\n\n---\n\n## Tools\n\n| Tool | What it does |\n|---|---|\n| **HyperExecute** | AI-native test orchestration. Generates HyperExecute YAML and test runner commands, triggers jobs, and reports status — no manual YAML authoring. |\n| **Automation** | Triages test failures by pulling execution details, command logs, network logs, and console errors into one place for root-cause analysis. |\n| **SmartUI** | Explains visual regressions in plain English — pixel, layout, DOM, and perceptual differences, summarized rather than eyeballed. |\n| **Accessibility** | Runs WCAG and a11y audits against hosted URLs or local React apps, returning violations with remediation guidance. |\n| **Test Manager** | Covers the test management lifecycle — AI test case generation through to bulk result recording. |\n\n---\n\n## Prerequisites\n\n- A [TestMu AI account](https://www.testmuai.com/)\n- An MCP-compatible client (see below)\n- Node.js 18+ — only if your client needs the STDIO fallback\n\nAuthentication 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.\n\n---\n\n## Setup\n\nThe server endpoint is:\n\n```\nhttps://mcp.lambdatest.com/mcp\n```\n\n### Cursor\n\nAdd to `~/.cursor/mcp.json` (global) or `.cursor/mcp.json` (per project):\n\n```json\n{\n  \"mcpServers\": {\n    \"mcp-lambdatest\": {\n      \"url\": \"https://mcp.lambdatest.com/mcp\"\n    }\n  }\n}\n```\n\n### Claude Code\n\n```bash\nclaude mcp add --transport http mcp-lambdatest https://mcp.lambdatest.com/mcp\n```\n\n### VS Code / GitHub Copilot\n\nAdd to your MCP configuration:\n\n```json\n{\n  \"servers\": {\n    \"mcp-lambdatest\": {\n      \"type\": \"http\",\n      \"url\": \"https://mcp.lambdatest.com/mcp\"\n    }\n  }\n}\n```\n\n### Claude Desktop and other STDIO-only clients\n\nClients that don't yet support remote HTTP transport can connect through `mcp-remote`:\n\n```json\n{\n  \"mcpServers\": {\n    \"mcp-lambdatest\": {\n      \"command\": \"npx\",\n      \"args\": [\"-y\", \"mcp-remote@latest\", \"https://mcp.lambdatest.com/mcp\"]\n    }\n  }\n}\n```\n\n### Via Smithery\n\n```bash\nnpm install -g smithery\nsmithery mcp add testmuai/testmu-mcp\n```\n\n---\n\n## Supported clients\n\nCursor · Claude Code · Claude Desktop · GitHub Copilot · OpenAI Codex · Windsurf · Cline · Continue · Zed AI · JetBrains AI Assistant · Antigravity\n\nAny client implementing the Model Context Protocol should work. Clients with native remote HTTP support connect directly; the rest use the `mcp-remote` fallback above.\n\n---\n\n## Example prompts\n\nOnce connected, ask your assistant things like:\n\n```\nGenerate a HyperExecute YAML for my Playwright TypeScript tests and run it.\n```\n\n```\nMy last automation build failed — pull the console and network logs and tell me why.\n```\n\n```\nSummarise the SmartUI visual differences in my latest build.\n```\n\n```\nRun an accessibility audit on https://staging.example.com and list WCAG violations by severity.\n```\n\n---\n\n## Troubleshooting\n\n**Server doesn't appear after editing config**\nFully quit and reopen the client. Reloading the window is not enough for most clients to re-read MCP configuration.\n\n**Config not being picked up**\nValidate the JSON. A trailing comma or mismatched brace will cause the client to silently skip the entry.\n\n**`npx` not found (STDIO fallback)**\nConfirm 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.\n\n**Authentication loop or expired session**\nClear the stored authentication for this server in your client's MCP settings and reconnect to re-trigger the OAuth flow.\n\n---\n\n## Documentation\n\n- [MCP Server documentation](https://www.testmuai.com/support/docs/testmu-mcp-server/)\n- [Product overview](https://www.testmuai.com/mcp/)\n- [Smithery listing](https://smithery.ai/servers/testmuai/testmu-mcp)\n\n## Support\n\n- [TestMu AI Support](https://www.testmuai.com/support/)\n- Open an issue in this repository for problems with the setup guide itself\n\n---\n\n<p align=\"center\">\n  Built by <a href=\"https://www.testmuai.com/\">TestMu AI</a> (formerly LambdaTest)\n</p>\n",
