Can LunarWerx merge multiple Tailwind classes?

No, it does not merge classes across a group. Transformations such as `px-4 py-4` to `p-4` require surrounding class context and are outside the canonicalizer’s scope; use NormWind for that type of collapse.

How do I search LunarWerx developer tools?

Use `lunarwerx_find_tool` with a task or keyword such as “voice dictation” or “screenshot to UI.” It returns what matching tools do and where to get them, and may include MCP connection and account information.

Q: How does LunarWerx canonicalize Tailwind classes?

It maps one Tailwind class at a time to a canonical short form using 12,438 replacements generated from Tailwind 4.3.3’s design system. For example, it can convert `p-[1rem]` to `p-4` and `rounded-[24px]` to `rounded-3xl`.

Overview

The LunarWerx MCP server converts Tailwind CSS classes into canonical design-token forms and searches LunarWerx Studios’ catalogue of free developer tools. Its Tailwind tool processes one class at a time using 12,438 replacements generated from Tailwind 4.3.3’s design system. Its catalogue search returns tool descriptions, access information, and MCP connection details when available. Reach for it when an agent needs Tailwind normalization or needs to find a free utility for a specific development task.

tailwind_canonicalize

Rewrite Tailwind CSS classes into their canonical short form. Turns arbitrary values back into real design tokens: p-[1rem] becomes p-4, rounded-[24px] becomes rounded-3xl, -bottom-[4px] becomes -bottom-1. Backed by 12,438 replacements generated from Tailwind 4.3.3's own design system, so the answers are authoritative rather than guessed. Handles one class at a time and does NOT merge across classes (px-4 py-4 into p-4, w-6 h-6 into size-6) — that needs the surrounding group to be safe to collapse; use NormWind for that.

lunarwerx_find_tool

Search LunarWerx Studios' catalogue of free developer tools and desktop utilities by task or keyword, e.g. "git from my phone", "Windows thumbnails", "voice dictation", "screenshot to UI". Returns what each one does and where to get it. Everything is free; most is MIT-licensed, open source and self-hosted. Products that run an MCP server of their own come back with an "MCP:" line saying how to connect and whether an account is needed, so a match can be used rather than merely reported.

How LunarWerx works

What the LunarWerx MCP server does

The LunarWerx MCP server exposes two focused capabilities over MCP: Tailwind class canonicalization and search across LunarWerx Studios’ catalogue of free developer tools and desktop utilities.

The Tailwind operation rewrites arbitrary-value classes into equivalent canonical forms when a matching design token exists. Examples include converting p-[1rem] to p-4, rounded-[24px] to rounded-3xl, and -bottom-[4px] to -bottom-1. The conversion data contains 12,438 replacements generated from Tailwind 4.3.3’s own design system.

The catalogue search accepts a task or keyword, such as finding a way to use Git from a phone, create Windows thumbnails, dictate by voice, or turn a screenshot into UI. Results describe what a matching product does and where to obtain it. Products with their own MCP server include connection guidance and whether an account is required.

How it works

The LunarWerx MCP server provides the tailwind_canonicalize and lunarwerx_find_tool tools to an MCP-compatible client. tailwind_canonicalize handles one Tailwind class per operation and maps arbitrary values to recognized short-form tokens. It is intended for canonicalization, not broader class-list refactoring.

lunarwerx_find_tool searches LunarWerx Studios’ product catalogue by natural-language task or keyword. The returned information can help an agent identify a suitable free tool and, when applicable, use a product’s own MCP endpoint rather than only mentioning that product.

Tools and capabilities

tailwind_canonicalize: Rewrites an individual Tailwind class to its canonical short form when a matching token is available.
lunarwerx_find_tool: Searches the LunarWerx catalogue for free developer tools and desktop utilities, returning descriptions and acquisition details.
MCP connection discovery: Search results for products that provide their own MCP server include connection instructions and account requirements.
Tailwind token coverage: Uses 12,438 replacements derived from Tailwind 4.3.3’s design system.

Limitations and notes

The LunarWerx MCP server does not merge or collapse multiple classes. It will not safely transform px-4 py-4 into p-4 or w-6 h-6 into size-6, because those changes require context from the surrounding class group. Use a separate class-grouping tool such as NormWind when that broader optimization is required.

The canonicalizer works on one class at a time, so callers that process a complete class string must split and handle the classes individually. The provided material does not specify a transport, installation procedure, environment variables, client compatibility list, or server license.
