Image Size MCP

A Model Context Protocol (MCP) service for retrieving image dimensions, supporting both URL and local file sources.

中文文档

Features

• Retrieve image dimensions from URLs
• Get image dimensions from local files
• Returns width, height, type, and MIME type information

Installation

npm install image-size-mcp

Usage

Using as an MCP Service

This service provides two tool functions:

1. get_image_size - Get dimensions of remote images
2. get_local_image_size - Get dimensions of local images

Client Integration

To use this MCP service, you need to connect to it from an MCP client. Here are examples of how to integrate with different clients:

Using with Claude Desktop

1. Install Claude Desktop from claude.ai/download
2. Configure Claude Desktop to use this MCP server by editing the configuration file:

{
  "mcpServers": {
    "image-size": {
      "command": "npx",
      "args": ["image-size-mcp"]
    }
  }
}

3. Restart Claude Desktop
4. Ask Claude to get image dimensions: "Can you tell me the dimensions of this image: https://example.com/image.jpg?"

Using with MCP Client Library

import { McpClient } from "@modelcontextprotocol/client";

// Initialize the client
const client = new McpClient({
  transport: "stdio" // or other transport options
});

// Connect to the server
await client.connect();

// Get image dimensions from URL
const urlResult = await client.callTool("get_image_size", {
  options: {
    imageUrl: "https://example.com/image.jpg"
  }
});
console.log(JSON.parse(urlResult.content[0].text));
// Output: { width: 800, height: 600, type: "jpg", mime: "image/jpeg" }

// Get image dimensions from local file
const localResult = await client.callTool("get_local_image_size", {
  options: {
    imagePath: "D:/path/to/image.png"
  }
});
console.log(JSON.parse(localResult.content[0].text));
// Output: { width: 1024, height: 768, type: "png", mime: "image/png", path: "D:/path/to/image.png" }

Tool Schemas

get_image_size

{
  options: {
    imageUrl: string // URL of the image to retrieve dimensions for
  }
}

get_local_image_size

{
  options: {
    imagePath: string // Absolute path to the local image file
  }
}

Technical Implementation

This project is built on the probe-image-size library for image dimension detection.
