The MCP server itself is free to connect, but it operates against your LambdaTest (TestMu AI) account, so you need a plan that covers the automation, accessibility, SmartUI, or HyperExecute features the tools reach. Usage bills against your account as normal.

What can the agent actually see?

For automation it reads test metadata plus command, network, and console logs; the bundled Accessibility, SmartUI, and HyperExecute tools add WCAG audits, visual regression analysis, and config generation respectively.

LambdaTest MCP server

OfficialLambdaTest (TestMu AI)Config last verified Jun 1, 2026

LambdaTest's official remote MCP server: triage automation failures, pull command/network/console logs, run accessibility and visual checks from an agent.

The LambdaTest MCP Server is the official integration from LambdaTest (now TestMu AI) that connects an AI assistant to its cloud testing platform so an agent can triage failures and reason about test runs without leaving the editor. Its headline job is automation failure triaging: given a test ID, the agent fetches detailed test metadata, retrieves the Selenium command execution logs, inspects network traffic, and reads browser console output to surface the error-level messages and warnings that explain why a run broke, then proposes a fix in the same conversation.

Beyond automation logs the hosted server bundles several capabilities behind one endpoint: an Accessibility MCP that runs WCAG/ADA audits against public URLs or a locally served build, a SmartUI MCP for visual regression analysis across pixel, layout, DOM, and perceptual layers, and a HyperExecute MCP that analyzes a project, generates YAML config and runner commands, and answers documentation queries. It is a remote Streamable HTTP server reached at https://mcp.lambdatest.com/mcp and authenticated with OAuth 2.1 (you are redirected to sign in on first use), so there is no local binary to install — point any MCP client at the URL, or use the mcp-remote bridge for stdio-only clients.

What you can do with it

Triage a failed cloud test from your IDE

Hand the agent a failing test ID and it pulls the command, network, and console logs from LambdaTest, reads the stack trace, and proposes a fix without you opening the dashboard.

Run an accessibility audit on a URL

Ask the agent to check a page for WCAG/ADA issues and it runs the Accessibility MCP against the public URL or a local build, returning a prioritized list of violations to fix.
