authenticator_mcp
Verified Safeby firstorderai
Overview
Enables AI agents to securely retrieve 2FA codes and passwords from a local Authenticator App for automated login processes.
Installation
npx -y authenticator-mcp --access-token=YOUR-KEYEnvironment Variables
- AUTHENTICATOR_ACCESS_TOKEN
Security Notes
The server design enhances security by communicating exclusively with a local desktop application (via 127.0.0.1) and requiring a generated access token for authentication. Input parameters for website and username are properly URL-encoded and validated using Zod. The access token is handled through environment variables or CLI arguments, not hardcoded. A minor concern is the override of `process.stdout.write` to silently filter non-JSON messages, which could obscure debugging information but does not appear to be a direct security vulnerability.
