README

Ketchup Draw MCP Server

npm version License: MIT

这是一个 MCP (Model Context Protocol) 服务器,集成了 Ketchup AI 的专业绘图能力和 URUSAI! 的图床服务。

它可以让 Claude Desktop 等 MCP 客户端具备“画图”能力:不仅仅是生成图片,还能自动优化提示词,并将生成的图片自动上传至云端,返回可永久访问的 URL。

Demo

✨ 特性

  • 智能提示词优化 (Prompt Engineering): 将简单的中文/英文短语(如“一只可爱的狗”)自动改写为包含光影、风格、细节描述的专业绘图提示词。
  • 高质量绘图 (AI Generation): 调用 Ketchup AI 引擎生成高分辨率图像。
  • 自动图床上传 (Auto Upload): 生成的图片会自动上传至 URUSAI!,并在对话中直接展示图片预览,同时提供永久链接。
  • 代理支持 (Proxy Support): 内置 undici 代理配置,完美解决国内网络环境下无法访问 URUSAI! 或 API 的问题。

🧰 工具详情 (Tools)

本服务器向 MCP 客户端暴露了以下两个工具,大模型可根据上下文自动调用:

1. optimize_prompt

用于将用户的简短描述转化为专业的英文绘图提示词。

  • 描述: Optimize a simple drawing prompt into a detailed professional prompt using Ketchup AI.
  • 输入参数 (Input Schema):
参数名 类型 必填 说明
prompt string 需要优化的原始提示词(例如:"cyberpunk city at night" 或 "赛博朋克城市")

2. generate_image

用于执行实际的绘图操作并上传。

  • 描述: Generate an image using Ketchup AI and upload it to URUSAI!. Returns the image URL.
  • 输入参数 (Input Schema):
参数名 类型 必填 说明
prompt string 详细的绘图提示词(建议先调用 optimize_prompt 获取)
ratio string 图片比例,必须是下方列表中的值之一(如 "16x9"

📐 支持的图片比例 (ratio)

在调用 generate_image 时,ratio 参数支持以下枚举值:

比例代码 尺寸 (WxH) 适用场景
1x1 1024 x 1024 头像、Instagram
16x9 1344 x 768 壁纸、视频封面
9x16 768 x 1344 手机壁纸、Stories
4x3 1152 x 896 传统照片
3x4 896 x 1152 肖像
21x9 1536 x 640 电影宽银幕
9x21 640 x 1536 长条幅
3x2 1280 x 832 风景
2x3 832 x 1280 海报

🚀 使用方法 (Claude Desktop)

无需克隆代码,直接修改 Claude Desktop 的配置文件即可使用 npx 运行。

1. 找到配置文件

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

2. 添加配置

将以下内容添加到 mcpServers 对象中:

{
  "mcpServers": {
    "ketchup-draw": {
      "command": "npx",
      "args": [
        "-y",
        "ketchup-draw-mcp-server"
      ],
      "env": {
        "HTTPS_PROXY": "http://127.0.0.1:7890"
      }
    }
  }
}

⚠️ 网络配置重要提示: 由于 URUSAI! 和 Ketchup AI 的服务器在海外,如果你在中国大陆,必须配置 env 中的 HTTPS_PROXY

  • 请将 127.0.0.1:7890 替换为你本地代理软件(如 Clash, v2rayN 等)的实际 HTTP 端口。
  • 如果没有配置代理,图片上传大概率会失败。
