Sitejar

Sitejar scans a webpage across six areas — accessibility, security headers, privacy, dark patterns, technical quality and SEO — and reports the exact fix down to the source code, then rescans to verify. It also ships as a remote MCP server so a coding agent (Claude Code, Cursor, VS Code) can scan a page it just built and write the fixes itself, no API key, OAuth sign-in. Free to scan, no signup for a basic scan; free plan includes 5 MCP scans a month.
