// how it works
Three steps. Your secrets stay home.
01
Install it.
Get the app for your computer from the downloads page. It takes minutes, and there is no account to create for the free plan.
02
Point your agent through it.
Send your agent's tool calls through Context Fence. It reads your rule file and learns what to block.
03
It blocks and logs.
A bad call is stopped before it runs. Every decision lands in a log on your machine, with the rule that fired it.
