Overview

Plango is a Mac security app aimed at developers who use AI coding agents such as Cursor, Codex or Claude Code. It watches what agents do and stops dangerous actions, lists the MCP servers your tools connect to, checks skills and plugins for hidden instructions, and moves plain-text keys from .env files into the macOS Keychain. It also includes a phishing warning, an app permissions audit and a firewall, and its AI model runs on the Mac. It runs on Apple-silicon Macs with macOS 15 or newer.
