> Use this tool when you need to securely authenticate with multiple services using two-factor authentication codes and passwords. It solves the problem of manual code entry and password retrieval, enabling AI assistants to assist with login workflows while maintaining security through token-based authorization.

## Description

The Authenticator MCP Server provides AI assistants with secure access to two-factor authentication codes and passwords stored in the Authenticator App. Developed by FirstOrder.AI, this TypeScript implementation exposes three key tools: retrieving 2FA codes, fetching passwords, and listing available accounts for specific websites. The server communicates with the local Authenticator App running on port 43457 and requires an access token for authentication. This integration is particularly valuable for workflows requiring secure login assistance across multiple services without manual code entry or password retrieval, enabling AI assistants to help with authentication while maintaining security through the token-based authorization system.
