authenticator_mcp
Verified Safeby firstorderai
Overview
Enables AI agents to securely retrieve 2FA codes, passwords, and account lists from a local desktop Authenticator App for automated login processes.
Installation
npx -y authenticator-mcp --access-token=YOUR_ACCESS_TOKENEnvironment Variables
- AUTHENTICATOR_ACCESS_TOKEN
Security Notes
The server's design inherently limits network exposure by communicating credentials solely with a local desktop Authenticator App via localhost (127.0.0.1). It utilizes `zod` for input validation and requires an access token, which can be provided securely via environment variables or CLI arguments. There is no usage of `eval` or similar dangerous functions, and no hardcoded secrets other than the expected localhost endpoint. The `process.stdout.write` override is an unusual but intentional measure to ensure only MCP protocol JSON messages are output.
