FerrumMCP is a browser automation server that implements the Model Context Protocol (MCP) by Anthropic. It provides AI assistants with the ability to navigate websites, interact with elements, extract content, and perform complex browser automation tasks through a simple, standardized interface.

Key Benefits:

• 🤖 AI-Native Design: Purpose-built for AI assistants like Claude
• 🔄 Session-Based: Multiple concurrent browser sessions with isolated configurations
• 🌐 Multi-Browser: Support for Chrome, Edge, Brave, and BotBrowser
• 🧩 Smart Automation: Cookie banner detection and CAPTCHA solving (⚠️ experimental)
• 📦 Easy Deployment: Docker, systemd, or Kubernetes ready
• 🔌 Dual Transport: HTTP and STDIO for maximum compatibility

✅ Session Management

• Create/manage multiple browser sessions
• Automatic cleanup (30min idle timeout)
• Custom browser configurations per session

✅ Navigation

• URL navigation with network idle detection
• Browser history (back/forward)
• Page refresh

✅ Interaction

• Click, hover, drag-and-drop
• Form filling with typing delays
• Keyboard input simulation
• Smart cookie banner acceptance (8 strategies, multi-language)
• AI-powered CAPTCHA solving (Whisper integration - ⚠️ experimental, under development)

✅ Extraction

• Text and HTML content extraction
• Screenshot capture (base64)
• Page metadata (title, URL)
• XPath-based text search

✅ Advanced

• JavaScript execution and evaluation
• Cookie management (get/set/clear)
• Shadow DOM querying
• Element attribute retrieval

🦾 BotBrowser Integration

• Anti-detection browser automation
• Fingerprint management with encrypted profiles
• Note: Requires valid trial/premium profiles (demo profiles cause session instability)

🔒 Security (v1.0+)

• Session limits
• Rate limiting
• Health check endpoint
• Non-root Docker user

📊 Observability

• File-based logging
• Health checks
• Metrics endpoint (planned)
