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

• 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.

Prerequisites

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

Image Processing Specifications

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

• Maximum 6 images per group
• Maximum height of 8000 pixels per group
• Maximum size of 30MB per group

If content exceeds these limits, images will be automatically split into multiple groups, and you'll need to paste (Cmd+V) multiple times.

Configuration

• Make sure Claude Desktop is installed and running.

• Install tsx globally if you haven't:

npm install -g tsx
# or
pnpm add -g tsx

• 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:

• Open Claude Desktop
• Click Claude on the Mac menu bar
• Click "Settings"
• Click "Developer"

Add the following to your MCP client's configuration:

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

Available Tools

• fetch: Retrieves URLs from the Internet and extracts their content as markdown. Images are automatically processed and prepared for clipboard operations.

Notes

• This tool is designed for macOS only due to its dependency on macOS-specific clipboard operations.
• Images are processed using Sharp for optimal performance and quality.
• When multiple images are found, they are merged vertically with consideration for size limits.
• Animated GIFs are automatically handled by extracting their first frame.
