}PLUGGEDIN_API_KEY[!IMPORTANT] Project status (October 2026): open source, community-driven. plugged.in, the hosted service, is moving to a new, separately developed platform. After that move, this repository will no longer run plugged.in. The code stays open source under its current license, and the community is welcome to carry it on: issues, pull requests, forks and new maintainers are welcome, and self-hosting remains supported. The cutover date will be announced here. At the cutover, the current service moves to v1.plugged.in and keeps running there until December 31, 2026. What this means
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

MCP_ALLOWED_HOSTS
Streamable HTTP: extra Host names accepted on the MCP endpoint (DNS-rebinding protection), e.g. the public name of a local reverse proxy.
Configuration
The proxy fetches server configurations from the plugged.in App
