WCAG Audit Agent
Supports UIby steventsao
Turn PDFs into accessible HTML twins with a deterministic WCAG 2.2 AA audit and human review gate.
What it does
This MCP App transforms static PDFs into live, screen-reader-friendly HTML twins. It performs a byte-level structural audit (checking for tags, language declarations, and alt text) and a visual contrast check, rendering the results in an interactive WCAG report UI.
Key features
- Deterministic Byte Audit: Checks StructTree roles and tags that vision models often miss.
- Accessible HTML Twins: Streams a semantic HTML version of the PDF via SSE.
- Human-in-the-Loop: Implements a durable review gate (Audited → Remediated → Attested).
- Automated Rollups: Maps evidence directly to WCAG 2.2 AA and PDF-UA criteria.
