## Description

Built by yamanoku, this server leverages the aria-query library to provide ARIA validation and information tools for web accessibility development. It offers three core functions: validating ARIA roles with their required and supported properties, validating ARIA attributes with type checking and value validation, and listing information about available ARIA roles and attributes. The server supports both Deno and Node.js runtimes with Docker deployment options, making it useful for developers building accessible web applications who need to verify ARIA implementation correctness and understand role relationships during development and testing workflows.
