firstorderai/authenticator_mcp

Overview

A secure MCP server built in TypeScript that lets AI agents interact with authenticator apps for generating time-based one-time passwords (TOTP). It wraps the Authenticator App via the Model Context Protocol, providing a controlled bridge between LLMs and authentication token generation.

Use cases

• Automate TOTP code retrieval in AI-driven workflows
• Enable AI agents to log into services requiring 2FA
• Integrate token generation into MCP-compatible assistant pipelines

Pros

• Provides a secure, standardized protocol for AI agent access to authenticator data
• Lightweight TypeScript implementation with clear MCP server structure
• Solves a real integration gap for AI automation involving 2FA

Cons

• Relies on the host system having an authenticator app configured, limiting portability
• Small community (36 stars) with limited track record or support
• Requires MCP compatibility on the client side, narrowing potential users
