It is designed for developers and QA engineers who need automated, actionable accessibility insights.

How to use Accessibility Hub?

Install the package globally with npm install -g AccesibilityHub, then add the configuration to your MCP client using the command npx with args ["-y", "AccesibilityHub"].
