This accessibility scanner, developed for the Model Context Protocol, integrates Axe Core with Playwright to perform automated web accessibility testing. Built with TypeScript, it leverages the MCP SDK to provide a standardized interface for running accessibility checks on web pages. The implementation focuses on ease of use and comprehensive reporting, offering detailed insights into accessibility issues. It's particularly useful for developers and quality assurance teams working on web applications, enabling use cases such as continuous integration testing, compliance auditing, and identifying accessibility barriers without manual inspection of each page element.
