概覽

AI 產生的概覽

遠端 MCP 端點,提供連接埠、時間、URL、HTTP 狀態、JSON 等小型查詢與驗證工具,以及若干推廣類索引工具。

可以做什麼
  • 查詢事實與格式:20 是否為常見連接埠、HTTP 狀態碼目錄、Jira 議題鍵與 Figma 連結格式、GitHub 儲存庫解析、路徑與 URL 安全性檢查
  • 取得時間資訊:目前 UTC 時間戳、指定 IANA 時區的時間、常見時區名稱清單
  • 驗證與正規化文字:JSON 是否有效、URL 的 origin/host/path、字元數統計、簡單 a+b 運算、維基百科標題是否存在
  • 擷取公開網路資料:URL 的 HTTP 狀態與內容類型、robots.txt 群組數量、Hacker News 首頁故事數、經 Open-Meteo 取得天氣與座標
  • 回傳固定範本與索引:三步思考範本,以及指向第三方工具閘道和廣告版位的索引工具
適用情境
適合需要快速、低風險查詢的情境,例如查詢某時區目前時間、公開網址的 HTTP 狀態、URL 或識別碼格式檢查、簡單算術,且不想在本機安裝任何東西。索引類工具面向尋找付費工具閘道或廣告版位的代理,而非一般任務。
執行需求
遠端 streamable HTTP 端點;未宣告任何套件、帳號、API 金鑰或請求標頭。需要能存取該端點及其查詢的公開網站(如 Open-Meteo、Hacker News、robots.txt 所在主機)。
安裝前請注意
多個工具會回傳第三方服務連結,包括按次付費的工具閘道、人員搜尋索引以及附 7 天試用的廣告投放服務;跟隨這些跳轉會離開本伺服器,可能涉及付費或註冊。天氣與地理查詢會傳送至 Open-Meteo,URL 檢查會存取目標網站。多數工具會捨棄輸入內容,但推廣類工具本質上是行銷入口而非中立工具。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 Port 20,將其新增到工作區。
  2. 為需要使用其工具的對話啟用該服務。

Web executable,透過 Streamable HTTP。 遠端服務在工作區中設定後即可從網頁執行環境執行。

交給代理程式安裝

把這段提示詞貼上到 Claude Code、Codex、Cursor 等代理程式,或 SourceWeft 對話中。代理程式會讀取該伺服器的安裝指南,先向你展示發布者、端點和登入方式,經你同意後再把它新增到你的客戶端。金鑰不會寫進任何命令。

閱讀 https://sourceweft.com/mcp/io.github.sadri-dridi%2Fport-20/install.md,並按其中說明把這個 MCP 伺服器接入我的客戶端。修改任何設定之前,先告訴我它的發布者、端點和登入方式,等我確認。不要把 API 金鑰寫進命令或我會提交的檔案;問我金鑰應從哪裡取得。

Named MCP utilities

Independently listed public MCP servers for autonomous clients. Each folder is one official registry name with its own converting intake.

Agent Ads doors

Doors that route autonomous agents to Agent Ads: labeled placement where agents look for tools, measured with daily HMAC nicknames, 7-day trial. Readiness doors also run a bounded website check.
