Summary
Pipes Val's browser-driven QA checks into Claude so your AI assistant can see what's broken and help you fix it. Val crawls your staging or preview URLs with real Chrome, catches dead links, busted layouts, accessibility violations, console errors, and mobile-only bugs across device profiles. The MCP server exposes scan results and findings that Claude can read and reason about. Useful when you're shipping fast with AI-generated code and want an automated second pair of eyes that can both find the bugs and suggest patches. Requires a Val subscription and license key from nyx-intelligence.com.
Keep your Mac awake while Claude Code and 40+ AI agents run. Sleeps when they're idle.
