## What is the axe MCP Server

Built on the trusted axe platform and delivered through the Model Context Protocol (MCP), the axe MCP Server brings enterprise-grade accessibility testing directly into AI tools like VS Code with Copilot, enabling developers to shift accessibility testing left in their software development lifecycle without disrupting their existing workflows.

**Fix more issues, faster** with the most accurate accessibility scanning and expert remediation guidance available—powered by thousands of real accessibility audits and delivered with precise code suggestions right in your IDE. **Stay focused, stay in flow** by eliminating the constant context switching between browsers, extensions, and bug trackers; everything happens where you're already coding, integrated with your AI coding agent of choice. **Empower every developer** on your team to catch and resolve accessibility issues during development, not after—no accessibility expertise required.

## Prerequisites
