}You can securely access 2FA codes and passwords through the Authenticator App MCP Server, enabling AI agents to assist with automated login tasks while keeping credentials protected. This server exposes your Authenticator App securely to compatible MCP clients so you can automate credential retrieval within trusted workflows.
You interact with the MCP server from your AI agent’s client. Ask the agent to retrieve a 2FA code or password for a specific website or account. The agent will fetch the credential through the MCP server, then use it to automate the login process on your behalf. Ensure your access token is configured in your MCP client so the server can authenticate your requests.
Prerequisites: You need Node.js and npm installed on your machine to run MCP clients that support stdio configurations.
Follow these steps to configure the Authenticator App MCP Server in your MCP client configuration.

}Or you can set the access token in your environment configuration as AUTHENTICATOR_ACCESS_TOKEN and omit it from the command line. Ensure you replace YOUR-KEY with the actual access token you generate.
1. Launch the desktop version of Authenticator App · 2FA. 2. Open Settings and find the MCP Server section. 3. Turn the MCP Server ON, then generate your access token. 4. The access token is shown only once; copy it immediately and add it to your MCP client configuration.
Treat the access token like a password. Keep it confidential and only supply it to trusted MCP clients. Rotate tokens if you suspect compromise and revoke tokens from your Authenticator App settings if needed.
This MCP server is designed specifically for use with Authenticator App · 2FA and works with compliant MCP clients that support stdio-based server configurations.
