The MCP Era: Introducing MCP Servers for Automation, SmartUI, and Accessibility for AI-Native Testing

Automation MCP Server: Transforming Test Failure Triaging

The new Automation MCP Server simplifies the often time-consuming process of triaging test failures. By creating a direct connection between AI assistants and your TestMu AI test execution data, it allows developers and QA engineers to quickly identify, understand, and resolve issues without leaving their development environment.

Note: Try out the all-new Automation MCP Server here!

Why Choose Automation MCP Server:

• Seamless IDE Integration: Access and analyze your test execution data directly from your IDE or editor.
• Intelligent Root Cause Analysis: Quickly triage and troubleshoot test failures to identify the underlying issues.
• Accelerated Development: Fix test code based on accurate failure analysis, reducing debugging cycles.
• Comprehensive Log Analysis: Leverage network logs, Selenium logs, and console logs to pinpoint bottlenecks and failures.

How It Works:

Automation MCP Server provides five powerful tools that give you complete visibility into your test execution:

• Automation Test Details: Retrieve comprehensive information about specific tests.
• Automation Command Logs: Access execution logs for all Selenium commands.
• Automation Network Logs: Analyze browser traffic and network behavior during tests.
• Automation Console Logs: Review browser console outputs, including errors and warnings.
• Automation MCP Server: Core interface that connects your AI assistant to TestMu AI data.
• upload_app Tool: Upload mobile applications for testing.

SmartUI MCP Server: Human-Centric Visual Regression Intelligence

Visual bugs often go unnoticed by machines but are obvious to humans. The SmartUI MCP Server bridges this gap by simulating human perception to analyze UI changes intelligently. It doesn’t just spot differences, it interprets what matters, why it matters, and how to fix it — just like a seasoned frontend developer would.

Note: Try out the all-new SmartUI MCP Server , built to think like your users!

Why Choose SmartUI MCP Server:

• Automated Visual Debugging: Detects visual regressions and UI layout shifts without manual intervention.
• Human-Like Interpretation: Understand changes through the lens of user perception using cognitive principles.
• Context-Aware Fixes: Receive accurate UI fix suggestions based on visual evidence.
• Rapid Root Cause Analysis: Identify the exact UI elements responsible for changes.
• Multi-Layered Analysis: Perform independent or combined analysis across pixel-level, layout, DOM structure, and perceptual dimensions.
• Developer-Ready Outputs: Get clear, actionable insights designed for frontend teams.

SmartUI MCP Tools for You to Explore:

• getSmartUIResources: Fetches all visual assets for a comparison run.
• summarizeSmartUIPixelDiff: Identifies and explains raw pixel differences between screenshots.
• summarizeSmartUILayoutDiff: Detects spacing, alignment, and size-related layout issues.
• summarizeSmartUIDomDiff: Describes changes in DOM structure and attributes.
• analyzeSmartUIHumanDiff: Simulates how a human would perceive the visual changes.
• analyzeSmartUIRun: Provides a full debugging summary across all analysis layers.
• getSmartUIScreenshotInfo: Retrieve metadata and details about SmartUI screenshots.
• downloadSmartUIDomFiles: Download DOM structure files for deeper analysis.

Accessibility MCP Server: AI-Native A11y Testing for Web & Local Apps

Ensuring your application is accessible to everyone isn’t just best practice – it’s essential. Yet, validating accessibility across public sites and local environments is often manual and fragmented.

TestMu AI’s Accessibility MCP Server solves this by integrating seamlessly with your testing infrastructure to deliver AI-native audits using the Model Context Protocol (MCP).

Whether you’re testing a public site or a local React app, it provides detailed reports and actionable insights to help you identify and resolve accessibility (a11y) issues efficiently.

Note: Try out the all-new Accessibility MCP Server today!

Why choose Accessibility MCP Server:

• Full-Spectrum Testing: Analyze both publicly hosted websites and local front-end React applications.
• Detailed Accessibility Reports: Generate shareable, comprehensive reports that surface all accessibility violations and suggestions.
• Intelligent Remediation: Get context-aware fixes and improvement suggestions directly within your workflow.
• Seamless AI Integration: Utilize natural language commands via Cline in VS Code to run a11y tests without switching tools.
• Cross-Team Collaboration: Share findings and reports with designers, developers, and testers to drive inclusive design practices.

Accessibility MCP Tools You Should Know:

• getAccessibilityReport: Fetches a comprehensive accessibility report for any public URL.
• buildLocalAppForAnalysis: Builds and serves your local React app to identify accessibility issues during development.
• analyseAppViaTunnel: Helps in local app tests analysis, which are already running in TestMu AI via TestMu AI tunnel for accessibility failures.
