Authenticator App MCP Server is a secure MCP (Model Context Protocol) server that enables AI agents to interact with the Authenticator App, providing seamless access to 2FA codes and passwords to assist with automated login processes while maintaining security. The server bridges the gap between AI assistants and secure authentication, simplifying credential management across platforms and websites. How it works: In an AI agent's chat interface, request a 2FA code or password for a target site; the agent securely retrieves the credential and can use it to automate the login process. It is designed for use with the Authenticator App Desktop version. Getting started: configure the MCP client with an 'Authenticator App MCP' server entry (examples for MacOS/Linux and Windows are provided). You must create an Authenticator App access token; tokens are displayed only once and should be copied immediately or supplied via environment variable (AUTHENTICATOR_ACCESS_TOKEN). The README also covers enabling MCP Server in the Authenticator App Settings, and token usage via command-line arguments or environment variable.
