wcagc MCP

The wcagc MCP server enables AI assistants to perform deterministic accessibility scans using axe-core. It supports scanning public URLs, checking PDF/UA structure, crawling registered sites, analyzing root causes, replaying user journeys, and retrieving violation trends. The server provides structured findings with severity counts and coverage disclaimers, integrating with Claude, ChatGPT, and local clients via stdio or remote connections.
