A comprehensive proxy that combines multiple MCP servers into a single MCP. It provides discovery and management of tools, prompts, resources, and templates across servers, plus a playground for debugging when building MCP servers.
Documentation
Overview
The plugged.in MCP Proxy Server is a powerful middleware that aggregates multiple Model Context Protocol (MCP) servers into a single unified interface. It fetches tool, prompt, and resource configurations from the plugged.in App and intelligently routes requests to the appropriate underlying MCP servers. This proxy enables seamless integration with any MCP client (Claude, Cline, Cursor, etc.) while providing advanced management capabilities through the plugged.in ecosystem.
Key Features
- Built-in AI Playground: Test your MCPs instantly with Claude, Gemini, OpenAI, and xAI without any client setup
- Universal MCP Compatibility: Works with any MCP client including Claude Desktop, Cline, and Cursor
- Multi-Server Support: Connect to STDIO, SSE, and Streamable HTTP MCP servers
- Dual Transport Modes: Run proxy as STDIO (default) or Streamable HTTP server
- Unified Document Search: Search across all connected servers with built-in RAG capabilities
- AI Document Exchange (RAG v2): MCP servers can create and manage documents in your library with full attribution
- Notifications from Any Model: Receive real-time notifications with optional email delivery
- Multi-Workspace Layer: Switch between different sets of MCP configurations with one click
- API-Driven Proxy: Fetches capabilities from plugged.in App APIs rather than direct discovery
- Full MCP Support: Handles tools, resources, resource templates, and prompts
- Custom Instructions: Supports server-specific instructions formatted as MCP prompts
