Score: 6.8/10 (Innovation: 6, Technical: 7, Documentation: 8, Utility: 6)

Aether is an MCP server that integrates with coding agents like Claude Code and Cursor to scan web pages for WCAG 2.1 AA accessibility violations using Playwright and axe-core across multiple viewports. It goes beyond detection by providing ready-to-apply fixes verified in a real browser, with optional contextual fixes from a hosted API. The project stands out by grounding suggestions in actual measurements rather than markup inference and by offering a complete scan-fix-verify loop.

Target audience: frontend developers, web developers, accessibility engineers, QA engineers
