magg

Overview

Magg is a meta-MCP server that acts as a central hub for managing multiple MCP servers. It allows LLMs to search for, add, configure, and proxy MCP servers dynamically. The project provides tools for server management, configuration persistence, and real-time messaging across multiple MCP servers. With support for various transport protocols and authentication methods, Magg offers a comprehensive solution for extending LLM capabilities at runtime.
