}Tools
HyperExecute- AI-native test orchestration: generates test runner commands and HyperExecute YAML, monitors jobs, surfaces session details.
Automation- Triages automation test failures by pulling execution data and command, network and console logs for root-cause analysis.
SmartUI- Returns natural-language summaries of pixel, layout, DOM and perceptual differences from SmartUI comparison runs.
Accessibility- Runs accessibility checks on hosted URLs or local React apps with remediation guidance.
Test Manager- Covers the test management lifecycle from AI test case generation to bulk result recording, milestones and coverage.
As documented on October 17, 2026. A running server reports its current list through tools/list.
Notes and caveats
- LambdaTest has rebranded as TestMu AI; the endpoint keeps the lambdatest.com domain.
- Hosted only: the GitHub repo is a setup guide (MIT), not server source, and there is nothing to self-host.
- Requires a TestMu AI account; OAuth sign-in redirects to testmuai.com on first use.
- STDIO-only clients connect through the third-party mcp-remote bridge (generic snippet).
- The five tools are product areas as documented, not exact MCP function names.
- No beta/GA label stated; no release history published.

- BrowserStack
BrowserStack MCP server
Connects AI agents to the BrowserStack testing platform to run manual and automated tests on real devices and browsers, debug failures, run accessibility scans, manage test cases and load tests, and use BrowserStack AI agents. Available as a hosted remote server (OAuth) or a local npm server (username and access key).
Transport: Streamable HTTP, stdioAuth: OAuth or API key - BuildkiteStatus: GA
Buildkite MCP server
Open source MCP server, offered as a Buildkite-hosted remote endpoint or a local binary/container, that exposes Buildkite Pipelines and Test Engine data so an agent can inspect pipelines, builds, jobs, logs, artifacts and tests and, with write access, trigger, retry or unblock builds.
Transport: Streamable HTTP, stdio, SSEAuth: OAuth or API key - CircleCIStatus: GA
CircleCI hosted MCP server
Hosted MCP server run by CircleCI that lets an agent list and inspect CI runs, workflows and jobs, read job logs and test results, rerun or cancel workflows, and export usage data.
Transport: Streamable HTTPAuth: OAuth or API key - JamStatus: GA
Jam MCP server
Hosted MCP server that lets AI coding tools open a Jam bug recording and load its context (video frames, transcript, user events, console logs, network requests, metadata). It also exposes tools to search Jams, comment, organize folders, and manage recording links.
Transport: Streamable HTTPAuth: OAuth or API key - JetBrainsStatus: GA
TeamCity MCP server
MCP endpoint exposed by TeamCity servers that lets AI agents read build logs, query the TeamCity REST API, queue personal builds and, in brave mode, create, edit or delete pipelines and build configurations.
Transport: Streamable HTTPAuth: OAuth or API key - SonarSource
SonarQube MCP server
Connects AI coding agents to SonarQube Server or SonarQube Cloud code quality and security data: issues, quality gates, security hotspots, coverage, measures, dependency risks and code snippet analysis. Runs locally as a container or JAR (stdio or Streamable HTTP), or as a hosted server embedded in SonarQube Cloud.
