AgentWarden
Antivirus for AI agents. Know what the AI on your computer is actually doing.
Free download for Mac · Windows from the Microsoft Store · iPhone companion coming soon
Watches AI coding agents and AI tools on your Mac or PC, compares what they do with what you asked for, and tells you in plain words when something is off.
Who it is for
For developers
Claude Code, Codex and other coding agents: off-task actions, decoys that no real task touches, containment of a hijacked session, signed detection rules that update themselves.
For everyone else
AI scams and phishing, hidden instructions in documents and pages, lookalike links, QR codes and fake support numbers, explained in plain words.
What it does
Hijacked by what it read
Spots hidden instructions in a page or file followed by an action you never asked for.
Credential hunting
Notices agents reaching for SSH keys, keychains, cloud tokens or browser passwords the task never needed.
Skills, plugins and MCP
Reads every skill, plugin and MCP server offline before it can do harm.
Persistence and tampering
Login items, launch agents and attempts to switch off security tools, AgentWarden included.
Quiet by design
About 1% CPU. Actions that match what you asked for stay quiet, and it never interrupts your work.
Stays on your computer
Transcripts and findings never leave your machine. Alerts go only where you send them.
Privacy
Your code and transcripts stay on your computer. Activating a licence sends only your email and a one-way fingerprint of the computer.
