Let AI work autonomously — not without limits

AI today doesn't just answer you.
AI is now operating your computer on your behalf.
20131 is a security runtime that runs between AI agents and your devices.
It identifies AI, tools, MCP, processes, and sensitive resources — and controls high-risk actions before they take effect.
Let AI work autonomously, not without limits.

The model we build to

Not: AI Decides → Security Hopes. AI may propose actions and autonomously execute authorized tasks — but the security boundary is never decided by the AI itself.

Why now

Agents write files, run commands, call MCP tools and reach the network while you sleep. Each new agent, skill, or MCP server quietly widens that attack surface. You cannot review thousands of agents by hand — and you should not have to.

What 20131 does

• Automatically discovers agents, skills, MCP servers, tools, and child processes
• Evaluates every action against policies, task capability, resource sensitivity, and behavior chains
• Enforces at the native layer, before side effects happen
• Learns continuously with confidence, quarantine, and trust decay — and recovers automatically
• Keeps the core local-first: protection does not fail when the cloud is down

Join the Early Access waitlist

Status: under active development. Early Access starts as a local-first behavioral monitor for Windows, macOS, and Linux (observe, alert, audit); enforcement and recovery follow in later phases. We state current capabilities and limits explicitly on the Security and Supported platforms pages.
