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 🙏

Published

MCP server that annotates any web page with hover labels — zero extensions, any browser

Readme

UI Annotator MCP

npm version license GitHub stars GitHub forks

English | 廣東話

Hover 任何 element 就睇到佢叫咩名 — 任何 browser,零 extension。

一個 MCP server,幫任何網頁加上互動式 hover 標註。開個 proxy URL,hover 任何 element,即刻見到佢個名。同你嘅 AI 助手講「將 sidebar 整闊啲」— 佢即刻知你講邊個。

Demo

問題

同 AI coding 助手改 UI 嘅時候,最難嗰part唔係改 code — 而係形容你想改邊個 element

「左邊嗰個嘢...第二行...唔係,有個 icon 嗰個...」

你唔知佢叫咩名。AI 唔知你指緊邊個。你浪費時間喺溝通上而唔係 shipping。

解決方案

用 annotator proxy 開你個 page。Hover 任何 element — 即刻見到佢個名、CSS selector、尺寸。而家你同 AI 講同一種語言。

# Add 落 Claude Code
claude mcp add ui-annotator -- npx @mcpware/ui-annotator

# 開任何 browser
# http://localhost:7077/localhost:YOUR_PORT

搞掂。 零 extension。零 code 改動。零 setup。Chrome、Firefox、Safari、Edge — 任何 browser 都得。

功能

Hover 標註

Hover 任何 element 睇到:

  • Element 名(粉紅色)— 人類可讀嘅識別名
  • CSS selector(等寬字)— 技術參考
  • 內容預覽 — element 入面嘅文字
  • 尺寸 — 闊 × 高 (px)

Inspect Mode

撳 toolbar 嘅 Inspect 掣:

  • Click 任何 element → 複製佢個名去 clipboard
  • 所有頁面互動暫停(click 唔會觸發按鈕/link)
  • 再撳 Inspect 返回正常模式

MCP 工具

| 工具 | 做咩 | |------|------| | annotate(url) | 回傳 proxy URL 畀用戶喺任何 browser 開 | | get_elements() | 回傳所有偵測到嘅 UI elements(名、selector、位置) | | highlight_element(name) | 閃爍特定 element 畀用戶確認 | | rescan_elements() | 頁面改咗之後強制重新掃描 DOM | | inspect_mode(enabled) | 遠程切換 inspect mode |

點解唔直接用 DevTools?

| | DevTools | UI Annotator | |---|---|---| | 對象 | 識 DOM 嘅 frontend dev | 任何人 — QA、PM、設計師、junior | | 學習成本 | 要識 DOM tree、CSS selector、box model | Hover 就睇到 — 零學習 | | 溝通 | 「div.flex.gap-4 入面第二個 child 嗰個...」 | 「個 sidebar」 | | AI 整合 | 冇 — AI 睇唔到你 inspect 緊咩 | MCP — AI 見到同你一樣嘅 element 名 |

DevTools 係做 debugging 嘅。 UI Annotator 係做溝通嘅 — 畀人同 AI 有共同嘅 UI 詞彙。
