How to validate Tailwind design tokens with your AI

Connect this MCP to your IDE or AI client to enforce design system consistency. Your agent will catch every rogue hex code that breaks your theme.

Ask AI about this page

Short answer

How do I make sure my AI uses my Tailwind theme variables?

Your agent uses the validation tool to scan your files for hardcoded colors, spacing, or font sizes that don't match your @theme configuration. It identifies these discrepancies and suggests the correct Tailwind utility classes. You'll see exactly where your code deviates from your design system.

The results.

Where every violation lands.

The AI categorizes every issue it finds so you can clean up your codebase.

CRITICAL

Hardcoded hex codes

The AI flags any direct color values that bypass your theme. You get the exact line number and the variable name that should have been used.

WARNING

Arbitrary values

It catches square bracket notation like w-[432px] that ignores your spacing scale. You'll see which theme token matches that value best.

INFO

Theme mapping

The agent provides a map of your existing @theme variables. This helps you understand which tokens are available for future components.

HUMAN

Manual refactoring

The AI identifies the errors, but you decide when to commit the changes to your files. It won't rewrite your code without your permission.

The workflow

What your AI does when the code arrives.

The AI acts as a design system auditor, checking your implementation against your configuration.

  1. Scan codebase

    The agent reads your Tailwind configuration and your component files to build a baseline of allowed values.

  2. Detect violations

    It compares every CSS property and Tailwind class against your defined theme tokens.

    validate_tailwind_excellence

  3. Map replacements

    For every rogue value found, the agent finds the closest matching variable in your @theme block.

    validate_tailwind_excellence

  4. Report issues

    The AI presents a clear list of where your code deviates from the design system.

FAQ

How the validation behaves

  • 01

    Will the AI automatically change my code?

    No. The AI only identifies the violations and suggests the correct tokens. You must manually apply the changes to your files.

  • 02

    Can it fix my CSS files too?

    No. This tool specifically validates Tailwind classes and theme variables within your project files.

  • 03

    Does it work with any Tailwind setup?

    Yes, as long as your @theme or tailwind.config.js is accessible to the AI client.

  • 04

    Can it delete my design tokens?

    No. The AI has read-only access to your configuration files during the validation process.

  • 05

    What happens if a value doesn't match any token?

    The AI will flag it as an arbitrary value and suggest the nearest logical token from your theme.
