A secure MCP (Model Context Protocol) server that enables AI agents to interact with the Authenticator App. It provides seamless access to 2FA codes and passwords, allowing AI agents to assist with automated login processes while maintaining security. This tool bridges the gap between AI assistants and secure authentication, making it easier to manage your credentials across different platforms and websites.

How it works

1. Open your AI agent's integrated chat interface (such as Cursor's agent mode).
2. Ask AI agent to retrieve your 2FA code or password for your desired website and account.
3. AI agent will securely fetch these credentials, then can utilize them to automate your login process.

This MCP server is specifically designed for use with Authenticator App · 2FA.
