Image Download and Optimize MCP server for AI agents

This MCP server provides tools for downloading and optimizing images. It allows AI assistants to retrieve images from URLs and perform basic optimization tasks like resizing and quality adjustment using the Model Context Protocol (MCP).

Installation

# Clone the repository
git clone https://github.com/qpd-v/mcp-image-downloader.git
cd mcp-image-downloader

# Install dependencies
npm install

# Build the project
npm run build

Configuration

Add the server to your MCP configuration (e.g., in Claude Desktop's config):

{
  "mcpServers": {
    "image-downloader": {
      "command": "node",
      "args": ["/path/to/mcp-image-downloader/build/index.js"]
    }
  }
}

Available Tools

download_image

This tool downloads an image from a URL to a specified path.

Parameters:

url: URL of the image to download
outputPath: Path where to save the image

Example usage:

// Example of how the tool would be called by an AI assistant
await mcp.invoke("image-downloader", "download_image", {
  url: "https://example.com/image.jpg",
  outputPath: "/path/to/save/image.jpg"
});

optimize_image

This tool creates an optimized version of an image with various adjustment options.

Parameters:

inputPath: Path to the input image
outputPath: Path where to save the optimized image
width (optional): Target width (maintains aspect ratio if only width is specified)
height (optional): Target height (maintains aspect ratio if only height is specified)
quality (optional): JPEG/WebP quality (1-100)

Example usage:

// Example of how the tool would be called by an AI assistant
await mcp.invoke("image-downloader", "optimize_image", {
  inputPath: "/path/to/original/image.jpg",
  outputPath: "/path/to/optimized/image.jpg",
  width: 800,
  quality: 80
});

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "image-downloader" '{"command":"node","args":["/path/to/mcp-image-downloader/build/index.js"]}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "image-downloader": {
            "command": "node",
            "args": [
                "/path/to/mcp-image-downloader/build/index.js"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json
Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

{
    "mcpServers": {
        "image-downloader": {
            "command": "node",
            "args": [
                "/path/to/mcp-image-downloader/build/index.js"
            ]
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
