What can your AI agent access?

AI agents can do almost anything you can. That’s exactly the problem.

Your files, accounts, projects, and private data are all within reach. One wrong assumption can cause real damage.

Every file you can open

It may read, change, move, or delete your photos, documents, downloads, code, and private files.

Every service you connect

Email, GitHub, cloud storage, browsers, and other apps may become available to the agent.

Everything you’re building

One wrong instruction can break your app, overwrite working code, or publish something unfinished.

Anything it sees

Personal files, conversations, passwords, and private data can accidentally leave your computer.

Anything that charges automatically

An agent can consume paid AI, cloud, and software services much faster than expected.

AI agents don’t have to be malicious to be dangerous. They just have to misunderstand you once.

AI acts fast.
Leash checks first.

Stop dangerous actions before they happen.

Leash catches actions that could delete files, change important data, or break your project, and asks you first.
