Screen an agent's tool calls with Jev before they run.
Open github.com ↗How builders describe it
Screens an AI agent's tool calls before they run and tool results before the agent reads them. An MCP proxy plus a hooks adapter for a client's built-in tools.
Calibrated firewall for AI agent tool calls: screens MCP traffic through a proxy and a client's built-in tools through hooks, with policy thresholds and a local judgment log. Default screening uses TypeSafe Jev; starts in shadow mode (blocks nothing until you tune).
The decision Jev makes
Allow, flag or escalate a message, tool call or action.
Where it fits
Screening messages, tool calls and outputs before they cause trouble. Jev gives a fast, calibrated verdict that can sit in front of every request or agent action. All 131 safety & guardrails projects →
