Superargs

About

Superargs is a middleware wrapper that enables dynamic injection of arguments into MCP servers at runtime. Instead of pre-configuring servers with necessary arguments and credentials, users can provide these details on-the-fly, enhancing flexibility and reducing setup overhead. It forwards all MCP requests to the underlying child server and introduces a tool to manage these arguments, ensuring connected clients are aware of changes.

Key Features

• Dynamic argument injection into MCP servers.
• Provides change notifications for tools, prompts and resources.
• Comprehensive Model Context Protocol support, forwarding all requests to the child server.
• Ability to customize the argument update tool name.
