Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

百炼图片理解 MCP 服务器

让 Claude 能"看懂"图片的 MCP 工具,基于阿里云通义千问 VL 模型。

为什么需要这个工具

Claude 本身不具备视觉能力,通过这个 MCP 服务器,你可以:

  • 发送图片链接或本地图片给 Claude 分析
  • 截图后直接粘贴,让 Claude 解释内容
  • 处理 base64 编码的图片数据

支持的模型:

  • qwen-vl-plus(默认):性价比之选
  • qwen3-vl-plus:第二代,性能更强
  • qwen-vl-max:最强能力,适合复杂场景

安装配置

1. 获取 API Key

访问 阿里云百炼平台,开通大模型推理服务后创建 API Key。

2. 配置 Claude Desktop

编辑 ~/Library/Application Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "bailian-image": {
      "command": "npx",
      "args": ["bailian-image-understanding-mcp"],
      "env": {
        "DASHSCOPE_API_KEY": "你的API密钥",
        "QWEN_VISION_MODEL": "千问模型code",
        "BAILIAN_REGION": "cn-hangzhou"
      }
    }
  }
}

4. 重启 Claude Desktop

配置完成后重启,即可在对话中使用图片分析功能。

在 Claude 中使用

配置好后,直接对话即可:
