Axe Accessibility

Accessibility testing and remediation using the axe MCP Server. Use when creating or modifying UI code (HTML, JSX, TSX, Vue, Svelte, CSS) to ensure accessibility compliance. Triggers on tasks involving web pages, components, forms, navigation, modals, tables, images, or any user-facing markup. Also use when explicitly asked to check accessibility or run an axe scan.

axe Accessibility Skill

Test web pages for accessibility violations and get AI-powered remediation guidance using the axe DevTools MCP Server.

Prerequisites

Docker running locally
AXE_API_KEY environment variable set
Docker image pulled: dequesystems/axe-mcp-server:latest

Tools

The wrapper script at scripts/axe-mcp.js (Node.js — no extra dependencies) provides two tools:

analyze

Scan a live web page for accessibility violations. Requires a URL (works with localhost).

node scripts/axe-mcp.js analyze <url>

Returns JSON-RPC response. The violations are in result.content[0].text (JSON string) under the data array. Each violation has: rule, impact, description, selector, source, helpUrl.

remediate

Get AI-powered fix guidance for a specific violation. Handles HTML with quotes/brackets safely.

node scripts/axe-mcp.js remediate <ruleId> <elementHtml> <issueRemediation> [pageUrl]

Returns general_description, remediation, and code_fix in result.content[0].text.

tools-list

List available MCP tools.

node scripts/axe-mcp.js tools-list

Workflow

When modifying UI code and a live page is available:

Analyze — node scripts/axe-mcp.js analyze <url>
Parse — extract violations from the JSON response
Remediate — for each unique rule violation, call remediate with ruleId, element HTML, and issue description
Apply — implement the recommended code fixes in source
Verify — re-run analyze to confirm zero violations

When no live page is available (static code review), apply accessibility best practices directly:

Images: alt text (or alt="" for decorative)
Forms: inputs need associated <label> elements
Interactive elements: keyboard accessible, visible focus
Color contrast: WCAG AA (4.5:1 normal text, 3:1 large text)
ARIA: valid, complete, not redundant with native semantics
Headings: proper hierarchy (h1 → h2 → h3)
Dynamic content: focus management for modals, SPAs, live regions

Notes

Each remediate call uses AI credits from your organization's allocation
The analyze tool spins up a real browser in Docker — allow ~30s for results
Works with localhost URLs for local development testing

Note: Requires a paid Axe DevTools for Web subscription.
