## Description

Opgen MCP Server is a password generation implementation based on 1Password's SPG library, offering secure password creation through a standardized interface. Developed by syumai, it provides two main tools: character-based password generation with configurable length and character sets, and word-based password generation with customizable word counts, separators, and capitalization schemes. The server automatically copies generated passwords to the clipboard, making it particularly useful for applications requiring secure credential creation without manual password handling. The implementation leverages the Model Context Protocol to make sophisticated password generation capabilities easily accessible to AI assistants.
