What is the MagentaA11y MCP Server?

The MagentaA11y MCP Server is a tool server specifically designed to provide accessibility standards. It is based on the open - source MagentaA11y project by T - Mobile and offers a complete set of accessibility design standard query interfaces for AI assistants (such as Claude). Through this server, you can easily obtain the accessibility design standards for web components and native mobile application components, including acceptance criteria, developer notes, and platform - specific instructions.

How to use the MagentaA11y MCP Server?

Using the MagentaA11y MCP Server is very simple: First, install the server via npm or the Claude Code CLI. Then, add the corresponding MCP server configuration to your AI assistant settings. After installation, you can directly ask your AI assistant about the accessibility standards of various components, and the server will automatically search the MagentaA11y database and return relevant information.

Use cases

This server is particularly suitable for the following scenarios: 1. Developers need to refer to accessibility standards when writing code. 2. Designers need to ensure that UI components meet accessibility requirements when designing. 3. Testers need to verify the accessibility compliance of applications. 4. Product managers need to understand accessibility acceptance criteria. 5. Teams need to quickly consult standards during accessibility audits.
