A Model Context Protocol server that manages, aggregates, and proxies other MCP servers, enabling LLMs to dynamically extend their own capabilities.

What is Magg?

Magg is a meta-MCP server that acts as a central hub for managing multiple MCP servers. It provides tools that allow LLMs to:

  • Search for new MCP servers and discover setup instructions
  • Add and configure MCP servers dynamically
  • Enable/disable servers on demand
  • Aggregate tools from multiple servers under unified prefixes
  • Persist configurations across sessions

Think of Magg as a "package manager for LLM tools" - it lets AI assistants install and manage their own capabilities at runtime.
