MCP Server Submission: plugged.in MCP Proxy

Overview

plugged.in MCP Proxy is a comprehensive MCP aggregator that provides access to 100+ MCP servers through a single unified interface.

Key Features

• 🔄 Unified Access: Single connection point for all your MCP servers
• 🔍 Smart Discovery: Automatically discover and catalog capabilities from connected servers
• 📚 RAG Integration: Built-in document library with semantic search across your knowledge base
• 🔔 Notifications: Real-time activity tracking with optional email delivery
• 🔐 Enterprise Security: AES-256-GCM encryption, OAuth 2.1, rate limiting, and sandboxing
• 🌐 Multi-Transport: Supports STDIO, SSE, and Streamable HTTP protocols
• ⚡ Performance: Smart caching for instant tool availability
