DEV 展示：MCP Browser Agent 以 FastMCP 和 Playwright 實現自主網頁自動化
Show DEV: MCP Browser Agent — Autonomous Web Automation with FastMCP and Playwright
MCP Browser Agent 是一個以 Python 建構的 MCP 伺服器，整合 FastMCP、browser-use 和 Playwright，讓 Cursor、Claude Desktop 等兼容的 AI 用戶端自動執行瀏覽器任務。它可擷取結構化網頁資料並以 JSON 回傳，也能下載檔案並分類儲存至本機目錄；目前仍在積極開發中。
MCP Browser Agent
An MCP (Model Context Protocol) server that enables AI assistants to automate browser-based tasks, extract structured web data, download files, and organize local outputs using Python.
The project integrates FastMCP, browser-use, and Playwright to provide browser automation tools to compatible MCP clients such as Cursor and Claude Desktop.
⚠️ Project status: In active development. Features and setup instructions may evolve as the implementation matures.
Features
- MCP Integration: Exposes browser automation capabilities as tools that compatible AI clients can discover and invoke.
- AI-Powered Browsing: Uses an autonomous browser agent to navigate complex websites and perform multi-step tasks.
- Structured Data Extraction: Collects web information and returns clean JSON results.
- File Downloads & Organization: Saves and automatically categorizes downloaded files into structured local directories.
- Python-Based Architecture: Modular setup keeping server, browser automation, configuration, and file management separated.
