qmax-mcp: local QA MCP server that scans URLs and runs Playwright repros for coding agents
bestofdesp · reddit · 2026-08-27
A developer released qmax-mcp (MIT, no account or API key for local tools), a local QA MCP server for coding agents with four tools:
- scanurl — console/network errors, accessibility, security headers, cookies, mixed content, page weight, Core Web Vitals
- inspectpage — page structure plus Playwright locators ranked by stability (test id > id > label-derived name > text > placeholder)
- generateplaywrightrepro — generates a spec for one specific finding
- runplaywrighttest — runs it and returns the result
Run via npx -y @qualitymax/qmax-mcp. Recent work cut noise: collapsing findings sharing one root cause, classifying Next.js prefetch/RSC ERRABORTED as informational, and naming the SDK behind stubbed-telemetry failures. Test execution asks for human approval bound to a code hash, with a process-start flag to opt out for isolated automation.
