VUDA - Visual UI Debug Agent Autonomous MCP Server for AI-Powered Visual UI Testing & Debugging VUDA (Visual UI Debug Agent) is an MCP (Model Context Protocol) server that empowers AI models to visually analyze, test, and debug web interfaces using Playwright. Any AI model, even without native vision, can inspect web pages, detect UI bugs, validate workflows, and measure performance automatically. --- Key Features Visual Analysis: Capture screenshots, map interactive elements, analyze page structure. Workflow Testing: Validate user journeys with step-by-step screenshots. Performance Monitoring: Measure load times, Core Web Vitals, and identify bottlenecks. API Testing: Validate backend endpoints and responses. Visual Comparison: Highlight UI changes between versions. Console Monitoring: Capture and log errors, warnings, and console output in real-time. --- Quick Start Install globally via npm: npm install -g visual-ui-debug-agent-mcp Or run directly: npx visual-ui-debug-agent-mcp Configure for Claude Desktop: { "mcpServers": { "vuda": { "command": "npx", "args": ["-y", "visual-ui-debug-agent-mcp"] } } } Supported Environments Node.js 18+ macOS, Linux, Windows --- Core Tools (Selection) Category Examples Visual Analysis enhanced_page_analyzer, screenshot_url, visual_comparison Workflow & Testing ui_workflow_validator, navigation_flow_validator, api_endpoint_tester Performance & Monitoring performance_analysis, console_monitor, sitemap_crawler Playwright Controls playwright_click, playwright_fill, playwright_screenshot Utility tunnel_helper, debug_memory --- Example Commands Screenshot: "Take a screenshot of https://example.com" Analyze Page: "Analyze the UI of https://myapp.com/dashboard" Test Login Flow: Navigate, fill credentials, submit, verify, and capture. Compare Versions: Highlight visual differences between two page states. Monitor Performance: Measure load times and identify bottlenecks. --- Why VUDA?
