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 🙏

MCP Fetch

Model Context Protocol server for fetching web content and processing images. This allows Claude Desktop (or any MCP client) to fetch web content and handle images appropriately.

Quick Start (For Users)

To use this tool with Claude Desktop, simply add the following to your Claude Desktop configuration (~/Library/Application Support/Claude/claude_desktop_config.json):

{
  "tools": {
    "fetch": {
      "command": "npx",
      "args": ["-y", "@kazuph/mcp-fetch"]
    }
  }
}

This will automatically download and run the latest version of the tool when needed.

Required Setup

  1. Enable Accessibility for Claude:
    • Open System Settings
    • Go to Privacy & Security > Accessibility
    • Click the "+" button
    • Add Claude from your Applications folder
    • Turn ON the toggle for Claude

This accessibility setting is required for automated clipboard operations (Cmd+V) to work properly.

Features

  • Web Content Extraction: Automatically extracts and formats web content as markdown
  • Article Title Extraction: Extracts and displays the title of the article
  • Image Processing: Processes images from web pages and optimizes them
  • Pagination Support: Supports pagination for both text and images
  • JPEG Optimization: Automatically optimizes images as JPEG for better performance
  • GIF Support: Extracts first frame from animated GIFs

For Developers

The following sections are for those who want to develop or modify the tool.

Prerequisites

  • Node.js 18+
  • macOS (for clipboard operations)
  • Claude Desktop (install from https://claude.ai/desktop)
  • tsx (install via npm install -g tsx)

Installation

git clone https://github.com/kazuph/mcp-fetch.git
cd mcp-fetch
npm install
npm run build

Image Processing Specifications

When processing images from web content, the following optimizations are applied:

  • Images are converted to JPEG format with quality control
  • Maximum width limited to 1200px by default
  • Maximum height limited to 1600px by default
  • Chroma subsampling (4:2:0) for better compression
  • MozJPEG optimization for smaller file sizes

Configuration

  1. Make sure Claude Desktop is installed and running.

  2. Install tsx globally if you haven't:

npm install -g tsx
# or
pnpm add -g tsx
  1. Modify your Claude Desktop config located at: ~/Library/Application Support/Claude/claude_desktop_config.json

You can easily find this through the Claude Desktop menu:

  1. Open Claude Desktop
  2. Click Claude on the Mac menu bar
  3. Click "Settings"
  4. Click "Developer"

Add the following to your MCP client's configuration:

{
  "tools": {
    "fetch": {
      "args": ["tsx", "/path/to/mcp-fetch/index.ts"]
    }
  }
}

Available Parameters

  • url (required): The URL to fetch
  • maxLength (default: 20000): Maximum length of content to return
  • startIndex (default: 0): Starting position in content
  • imageStartIndex (default: 0): Starting position for image collection
  • raw (default: false): Return raw content instead of processed markdown
  • imageMaxCount (default: 3): Maximum number of images to process per request
  • imageMaxHeight (default: 4000): Maximum height of merged image
  • imageMaxWidth (default: 1000): Maximum width of merged image

  • disableImages (default: false): Skip image processing
  • ignoreRobotsTxt (default: false): Ignore robots.txt restrictions

Notes

  • This tool is designed for macOS only due to its dependency on macOS-specific clipboard operations.

  • When multiple images are found, they are merged vertically with consideration for size limits.
  • Animated GIFs are automatically handled by extracting their first frame.
