Authenticator MCP Overview

The firstorderai/authenticator_mcp MCP server connects AI agents to the Authenticator App for retrieving account details, passwords, and current 2FA codes. It runs locally through the npm package and authenticates requests with an Authenticator App access token. Use it when an agent needs credential data for a supported login workflow, such as from Cursor's agent mode. The desktop Authenticator App must have its MCP Server enabled before the connection can work.

Primary Use Cases for Authenticator MCP:
  • Retrieve the account list available for a website login
  • Fetch a password for an authenticated login workflow
  • Obtain a current 2FA code during agent-assisted sign-in
  • Connect Cursor agent mode to Authenticator App credentials
