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."

中文

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

🛠️ Quick Start

Requirements

Python 3.10+
Playwright (pip install playwright && playwright install chromium)

Installation

# 1. Install dependencies pip install -r requirements.txt # 2. Install browser playwright install chromium # 3. Configure environment cp .env.example .env # Edit .env to set your API_KEYS

Start the Server

# Development mode uvicorn app.main:app --reload --port 8000 # Or use Docker docker compose up -d

Run as MCP Server

Add to your claude_desktop_config.json:

{ "mcpServers": { "nia-link": { "command": "python", "args": ["/path/to/Nia-Link/app/mcp_server.py"] } } }

Run Tests

pip install pytest python -m pytest tests/ -v

🚀 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
🧪 自動化測試: 53 個 pytest 測試覆蓋 API、服務與認證

🛠️ 快速開始
