念連 (Nia-Link) 🦞
The High-Performance Browser Interface for AI Agents. 「聽見網頁的脈搏,看見資料的靈魂。」 "Hear the pulse of the web, see the soul of the data."
Nia-Link is a Web Neuro-Link Engine purpose-built for AI agents. Natively embracing the Model Context Protocol (MCP), it gives Claude Desktop — or any MCP-compatible AI — 99% reliable web access and automation capabilities.

🚀 Core Advantages
1. Web Neuro-Link
Unlike traditional visual scrapers, Nia-Link listens directly to the browser's CDP (Chrome DevTools Protocol) network pulses. We don't wait for page rendering — we perceive data flow.
2. Action Map Registry
A memory hub with "cached semantics" architecture. Delivers action maps in 0.01s for frequently visited sites, reducing repeated computation costs by 90%.
3. Enterprise-Grade Trust
🔒 Snapshot Verified: Every extraction is timestamped and structurally validated.
🛡️ Sandbox Isolation: JavaScript executes in isolation, ensuring host safety.
📉 Token Optimized: Built-in intelligent filtering saves ~92% context space on average.
4. v0.9 New Features
🔄 Website Change Detection (
/v1/diff): Track content changes with unified diffs📋 Async Task Queue (
/v1/queue/*): Submit background scrape tasks⚡ Rate Limiting: Configurable per-key token bucket rate limiter
🧪 Automated Tests: 53 pytest tests covering API, services, and auth

🚀 核心優勢
1. 網頁神經連結 (Web Neuro-Link)
不同於傳統視覺爬蟲,Nia-Link 直接監聽瀏覽器底層的 CDP (Chrome DevTools Protocol) 網絡脈衝。我們不等待頁面渲染,我們感知數據流動。
2. 行動地圖註冊表 (Action Map Registry)
具備「緩存語意」架構的記憶中樞。針對常用網站提供秒級(0.01s)的行動地圖回傳,將重複運算成本降低 90%。
3. B2B 級別的可信賴感
🔒 快照驗證: 每一筆提取資料皆附帶時間戳記與結構驗證。
🛡️ 沙箱隔離: 在隔離環境執行 JavaScript,確保宿主機絕對安全。
📉 Token 優化: 內建智慧過濾,平均節省 92% 的上下文空間。
4. v0.9 新功能
🔄 網站變更偵測 (
/v1/diff): 追蹤內容變更,回傳 unified diff📋 非同步任務佇列 (
/v1/queue/*): 提交背景爬取任務⚡ 速率限制: 可配置的每 API Key Token Bucket 限流器

🔗 Nia-Link: The Sensory Nervous System for AI Agents
Nia-Link 是一個專為大語言模型(LLM)打造的 MCP (Model Context Protocol) 伺服器。它能賦予如 Claude Opus 4.7 或 GPT-5.4 等頂尖 AI Agent 強大的網頁導航、視覺感知與反爬蟲突破能力。
🚀 快速部署 (Railway One-Click)
我們建議使用 Railway 進行部署,以獲得最穩定的運行環境與極簡的 DevOps 體驗。
一鍵部署:點擊上方「Deploy on Railway」按鈕。
配置變數:在部署頁面填入你的 Bright Data 認證資訊(包含代理主機、帳號與密碼,詳見下方設定)。
完成連接:將產出的 URL 填入你的 AI Agent 配置中。
為什麼選擇 Railway? 現代架構師應專注於 AI 邏輯而非管理伺服器。關於 Railway 的深度架構優勢,請參閱我的分析文章:放下你的 SSH 與 Nginx:為什麼現代架構師都把基礎設施交給 Railway。
🛠️ 環境變數配置 (Environment Variables)
⚙️ 核心感知器配置:Bright Data (官方推薦)
Nia-Link 的動態網頁穿透能力,強烈依賴高品質的代理網路。我們官方推薦整合 Bright Data 來最大化 Agent 的感知穩定度與突破防護的能力。
在 Railway 的 Variables 區塊中,請配置以下變數:
BRIGHTDATA_PROXY_HOST:brd.superproxy.io:22225(預設代理端點)BRIGHTDATA_USERNAME: 您的 Bright Data Zone 帳號 (通常以 brd-customer- 開頭)BRIGHTDATA_PASSWORD: 您的 Bright Data Zone 密碼
