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 🙏

jsdesign-mcp-server

v2.0.0

Published

MCP server that bridges Instant Design (js.design) plugin to Cursor/Claude for design-to-code

Readme

jsdesign-mcp-server

即时设计(js.design)MCP Server:把设计稿节点树导出给 Cursor / Claude 等 Agent,用于设计稿 → 代码。

完整文档:https://github.com/nothing-sy/js.design

版本日志:CHANGELOG.md

架构

  • jsdesign-mcp daemon:WebSocket 桥,固定监听 ws://127.0.0.1:3847(可用 JSDESIGN_MCP_PORT),供即时设计插件连接。无任何客户端(agent + 插件)持续 15 分钟后自动退出(可用 JSDESIGN_MCP_IDLE_MS 覆盖;0 禁用)。
  • jsdesign-mcp(默认):Cursor 拉起的 stdio MCP;作为 agent 接入已有 daemon。若 daemon 未运行会自动 detached 拉起;退出 Cursor 不会立刻关掉 daemon(仍保留空闲宽限,便于插件保活)。

快速开始

1. 全局安装

npm i -g [email protected]

2. 配置 Cursor MCP

编辑 %USERPROFILE%\.cursor\mcp.json(macOS / Linux:~/.cursor/mcp.json):

{
  "mcpServers": {
    "jsdesign": {
      "command": "jsdesign-mcp"
    }
  }
}

在 Cursor Settings → MCP 中确认 jsdesign 为绿灯。

可选预热守护进程:

jsdesign-mcp daemon

3. 导入即时设计插件

  • 推荐:即时设计 → 插件 → 搜索 JsDesign MCP Bridge → 安装并运行
  • 开发者导入:克隆 https://github.com/nothing-sy/js.design ,再 插件 → 开发者 → 导入插件 → 选择 plugin/manifest.json

面板显示「已连接」即可(地址默认 ws://127.0.0.1:3847)。

4. 使用

在画布选中目标画板,让 Agent 调用 export_selection 即可写页面。
