使用说明
图像工具MCP
一种模型上下文协议(MCP)服务,用于检索图像尺寸和压缩图像,支持URL和本地文件源。
特性
- 从URL检索图像尺寸
- 从本地文件获取图像尺寸
- 使用TinyPNG API压缩URL中的图像
- 使用TinyPNG API压缩本地图像
- 将图像转换为不同格式(webp、jpeg/jpg、png)
- 返回宽度、高度、类型、MIME类型和压缩信息
示例结果
从figma网址下载并压缩
用法
用作MCP服务
此服务提供五个工具功能:
get_image_size-获取远程图像的尺寸get_local_image_size-获取本地图像的尺寸compress_image_from_url-使用TinyPNG API压缩远程图像compress_local_image-使用TinyPNG API压缩本地图像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集成的示例:
用法
{
"mcpServers": {
"image-tools": {
"command": "npx",
"args": ["image-tools-mcp"],
"env": {
"TINIFY_API_KEY": "<YOUR_TINIFY_API_KEY>",
"FIGMA_API_TOKEN": "<YOUR_FIGMA_API_TOKEN>"
}
}
}
}
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
}
}
get_local_image_size
{
options: {
imagePath: string; // Absolute path to the local image file
}
}
compress_image_from_url
{
options: {
imageUrl: string // URL of the image to compress
outputFormat?: "image/webp" | "image/jpeg" | "image/jpg" | "image/png" // Optional output format
}
}
压缩库图像
{
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
}
}

{
options: {
figmaUrl: string; // URL of the Figma file to fetch image links from
}
}
更新日志
- 2025-05-12: 更新了Figma API以支持其他参数,包括2倍图像缩放。
技术实现
此项目基于以下库构建:
环境变量
TINIFY_API_KEY-图像压缩功能所需。从获取API密钥 TinyPNG- 如果没有提供,压缩工具(
compress_image_from_url和compress_local_image)将不会注册
- 如果没有提供,压缩工具(
FIGMA_API_TOKEN-需要从Figma API获取图像链接。从获取您的API令牌 Figma- 如果没有提供,Figma工具(
figma)将不会注册
- 如果没有提供,Figma工具(
注:基本图像尺寸工具(get_image_size 和 get_local_image_size)无论API密钥如何,始终可用。
