Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

@aleph-alpha/lib-mcp

MCP (Model Context Protocol) Server for UI Library component discovery tools.

Overview

This package provides an MCP server that enables AI assistants (like Claude and Cursor) to discover and understand UI Library components. It offers tools to list available components and retrieve detailed documentation including props, examples, and usage guidance.

Installation

pnpm add @aleph-alpha/lib-mcp @aleph-alpha/ui-library

Usage

Configure MCP Server

Run the install command to configure your IDE:

# For Claude Code
npx @aleph-alpha/lib-mcp mcp-install

# For both Claude Code and Cursor
npx @aleph-alpha/lib-mcp mcp-install --cursor

After installation, restart your IDE to activate the MCP tools.

Available MCP Tools

Once configured, the following tools are available to your AI assistant:

list_components

Lists all available UI components. Supports optional filtering by name, category, or description.

list_components
list_components --filter="button"
list_components --filter="form"

get_component_docs

Retrieves full documentation for a specific component including:

  • Component description
  • Props with types, defaults, and descriptions
  • Sub-components (if applicable)
  • Usage guidance
  • Code examples
get_component_docs UiButton
get_component_docs Button  # "Ui" prefix is optional

Development

Building

pnpm build

Generating Component Metadata

pnpm generate:component-meta

Testing

pnpm test

How It Works

The MCP server reads component metadata from:

  1. types.ts: Extracts props, their types, descriptions, and component-level JSDoc tags (@category, @useCases, @keywords, @related)
  2. *.stories.ts: Extracts code examples and usage guidance from Storybook stories
  3. components-meta.json: Pre-generated metadata for faster lookups

CLI Commands

| Command | Description | |---------|-------------| | mcp-install | Configure MCP server for IDE | | serve | Start the MCP server (used internally by IDE) | | --help | Show help message |
