Install PoisonZero. v1.16.36

A lightweight daemon for the machine you want to protect. The one-line installer is recommended - it verifies the checksum automatically and sets up the service. Direct binaries with SHA-256 for your own or fully private distribution.

Quick install

  1. console.poisonzero.com - Create an install code in the panel - one code can enroll several devices.
  2. Run the command for your operating system - replace the example value with your install code.
  3. The daemon enrolls itself and starts as a service - the device shows up as “online” in the panel.

Agent integration (Claude Code, Codex, Gemini, Cursor)

Optional and opt-in: during install PoisonZero can add a “/poisonzero” command (short: “/pz”) to your local AI agents. It reports how many memory-poisoning attacks were blocked on this device - read-only and fully local, nothing leaves the machine. The interactive installer asks first (default: no); you can also pick the agents in the panel.
