How to audit component accessibility with your AI

Connect your AI to your codebase to run automated checks against accessibility standards. It catches errors in markup and contrast without you manually scanning every component.

Short answer

How can I audit component accessibility with my AI?

Your AI uses the validate_accessibility tool to scan your code for semantic HTML errors, keyboard traps, and color contrast failures. You get a clear list of specific violations to fix. This breakdown shows you how to run those checks.

Where every issue lands.

Audit outcomes

The AI categorizes every finding so you know what to fix first.

CODE

Markup errors found

The AI identifies missing ARIA labels or broken semantic structures. You get the exact lines of code that fail compliance.

NAV

Keyboard flow issues

It flags components that can't be reached via Tab key or have focus traps. This helps you keep navigation logical.

VISUAL

Contrast failures

The tool catches text that is too light against its background. You receive the specific hex codes that fail WCAG standards.

HUMAN

Manual review needed

Some logic-heavy accessibility issues require a person to test. The AI flags these edge cases for your final sign-off.

The workflow

What your AI does when the code arrives.

The AI handles the heavy lifting of scanning and pattern matching.

  1. Scan markup

    The AI inspects your HTML structure to ensure elements like buttons and inputs use the correct tags.

    validate_accessibility

  2. Check navigation

    It simulates keyboard interaction to find elements that are unreachable or lose focus unexpectedly.

    validate_accessibility

  3. Analyze contrast

    The agent calculates the luminosity ratio between text and background colors.

    validate_accessibility

  4. Report regressions

    It compares current results against previous passes to highlight new accessibility bugs.

FAQ

How this task behaves

  • 01

    Can the AI fix the code for me?

    No. The AI identifies the errors and tells you where they are, but you must manually apply the fixes to your codebase.

  • 02

    Does it check for screen reader compatibility?

    Yes, by checking for proper ARIA attributes and semantic HTML tags that screen readers rely on.

  • 03

    Can the AI delete my files?

    No. This MCP only has permission to read and validate your code. It cannot modify or delete any files.

  • 04

    Will it catch every single accessibility issue?

    No. While it catches many common technical failures, it cannot replace a manual audit by a human using assistive technology.

  • 05

    How does it know if my colors are wrong?

    It uses the validate_accessibility tool to calculate the contrast ratios of your CSS and inline styles.
