MFA Word (Security Gatekeeper)

Operational Protocol

1. Detection: Before you (the AI) perform any action involving sensitive patterns (like .env, .ssh, passwords, or deletions), you MUST call check_gate_status.
2. Standard Mode: If check_gate_status returns "OPEN", you may proceed. This session is valid for 15 minutes.

3. Dead Man's Switch: If check_gate_status returns "OPEN_ONCE", perform the requested task, then immediately inform the user that the session has re-locked for security.
4. Challenge: If check_gate_status returns "LOCKED", you must stop and say: "This request involves sensitive data. Please provide your Secret Word to continue."
5. Validation: Once the user provides a word, call verify_access. Only proceed if it returns "Access Granted."

Tools

initialize_mfa

Sets up the security layer and user preferences. - secret: The primary secret word. - super_secret: The emergency reset word. - sensitive_list: Array of strings or patterns to protect (default: .env, password, config, sudo). - use_dead_mans_switch: Boolean. If true, the gate locks after every single sensitive action.

verify_access

Validates the secret word provided by the user. - word: The word provided by the user in chat.

check_gate_status

Internal tool to check if the current session is authenticated.

reset_mfa

Resets the secret word using the super secret word. - super_word: The emergency reset word. - new_secret: The new primary secret.

这个 MFA 插件质量不错，核心安全机制扎实——密码用哈希加密、每次敏感操作后自动锁门、还能记录操作日志。它的功能比较完整，该有的验证、重置等功能都有。不足之处是万一服务器重启，之前解锁的会话就失效了需要重新验证，另外超时时间也不能自己调整。总体来说安全性设计较好，适合对文件访问有较高安全需求的用户使用。
