图像工具 MCP

铁匠徽章

用于检索图像尺寸和压缩图像的模型上下文协议 (MCP) 服务,支持 URL 和本地文件源。

中文文档

特征

  • 从 URL 中检索图像尺寸

  • 从本地文件获取图像尺寸

  • 使用 TinyPNG API 压缩来自 URL 的图像

  • 使用 TinyPNG API 压缩本地图像

  • 将图像转换为不同的格式(webp、jpeg/jpg、png)

  • 返回宽度、高度、类型、MIME 类型和压缩信息

示例结果

示例结果 1示例结果 2

从 figma url 下载并压缩示例结果 3

用法

用作 MCP 服务

该服务提供五种工具功能:

  1. get_image_size - 获取远程图像的尺寸

  2. get_local_image_size - 获取本地图像的尺寸

  3. compress_image_from_url - 使用 TinyPNG API 压缩远程图像

  4. compress_local_image - 使用 TinyPNG API 压缩本地图像

  5. figma - 从 Figma API 获取图像链接并使用 TinyPNG API 压缩它们

客户端集成

要使用此 MCP 服务,您需要从 MCP 客户端连接到它。以下是如何与不同客户端集成的示例:

与 Claude Desktop 一起使用

  1. claude.ai/download安装 Claude Desktop

  2. 获取 TinyPNG API 密钥:访问TinyPNG并获取您的 API 密钥

  3. 通过编辑配置文件来配置 Claude Desktop 以使用此 MCP 服务器:

{
  "mcpServers": {
    "image-tools": {
      "command": "npx",
      "args": ["image-tools-mcp"],
      "env": {
        "TINIFY_API_KEY": "<YOUR_TINIFY_API_KEY>",
        "FIGMA_API_TOKEN": "<YOUR_FIGMA_API_TOKEN>"
      }
    }
  }
}
  1. 重启Claude桌面

  2. 要求 Claude 获取图像尺寸:“你能告诉我这张图片的尺寸吗: https://example.com/image.jpg

  3. 要求 Claude 压缩图像:“您能压缩这张图片吗: https://example.com/image.jpg

  4. 要求 Claude 压缩本地图像:“您能压缩此图像吗:D:/path/to/image.png”

  5. 要求 Claude 压缩本地图像文件夹:“您能压缩这个文件夹吗:D:/imageFolder”

  6. 要求 Claude 从 Figma API 获取图像链接:“您能从 Figma API 获取图像链接吗: https://www.figma.com/file/XXXXXXX

与 MCP 客户端库一起使用

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" }

// Compress image from URL
const compressUrlResult = await client.callTool("compress_image_from_url", {
  options: {
    imageUrl: "https://example.com/image.jpg",
    outputFormat: "webp" // Optional: convert to webp, jpeg/jpg, or png
  }
});
console.log(JSON.parse(compressUrlResult.content[0].text));
// Output: { originalSize: 102400, compressedSize: 51200, compressionRatio: "50.00%", tempFilePath: "/tmp/compressed_1615456789.webp", format: "webp" }

// Compress local image
const compressLocalResult = await client.callTool("compress_local_image", {
  options: {
    imagePath: "D:/path/to/image.png",
    outputPath: "D:/path/to/compressed.webp", // Optional
    outputFormat: "image/webp" // Optional: convert to image/webp, image/jpeg, or image/png
  }
});
console.log(JSON.parse(compressLocalResult.content[0].text));
// Output: { originalSize: 102400, compressedSize: 51200, compressionRatio: "50.00%", outputPath: "D:/path/to/compressed.webp", format: "webp" }

// Fetch image links from Figma API

const figmaResult = await client.callTool("figma", {
  options: {
    figmaUrl: "https://www.figma.com/file/XXXXXXX"
  }
});
console.log(JSON.parse(figmaResult.content[0].text));
// Output: { imageLinks: ["https://example.com/image1.jpg", "https://example.com/image2.jpg"] }

### Tool Schemas

#### get_image_size

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

获取本地图像大小

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

从 URL 压缩图像

{
  options: {
    imageUrl: string // URL of the image to compress
    outputFormat?: "image/webp" | "image/jpeg" | "image/jpg" | "image/png" // Optional output format
  }
}

压缩本地图像

{
  options: {
    imagePath: string // Absolute path to the local image file
    outputPath?: string // Optional absolute path for the compressed output image
    outputFormat?: "image/webp" | "image/jpeg" | "image/jpg" | "image/png" // Optional output format
  }
}

figma

{
  options: {
    figmaUrl: string; // URL of the Figma file to fetch image links from
  }
}

变更日志

  • **2025-05-12:**更新 Figma API 以支持其他参数,包括 2 倍图像缩放。

技术实现

该项目基于以下库构建:

环境变量

  • TINIFY_API_KEY - 图像压缩功能所需。从TinyPNG获取 API 密钥

    • 如果未提供,则压缩工具( compress_image_from_urlcompress_local_image )将不会被注册

  • FIGMA_API_TOKEN - 从 Figma API 获取图片链接时需要。获取Figma的 API 令牌

    • 若未提供,则 Figma 工具( figma )将不会被注册

注意:无论 API 密钥如何,基本图像尺寸工具( get_image_sizeget_local_image_size )始终可用。
