jev-shield

What it does

Put a Jev check between an agent and its MCP tools to screen for unsafe calls and results.

How you can use it

If your automated assistant runs computer tasks or sends emails, you can place this screening tool in the middle. A developer can connect it using a setup key from AI Gateway. It checks each action to stop dangerous commands and hide private details before anything sends.

This tool estimates risk rather than offering a total guarantee, so tricky wording might slip past. Each check also adds about half a second of pause, and very long messages are cut short before review.
