Open github.com ↗How builders describe it
Sub-100ms security gate for AI agent tool calls, powered by TypeSafe's Jev (System-1) decision model. Single-request Choice/Noul/Score evaluation, dual-factor blocking matrix, calibrated-confidence routing, fail-closed parsing, zero-config local fallback. LangChain-ready.
Python runtime security gate for agent tool calls: TypeSafe Jev Choice/Noul/Score dual-factor evaluation with fail-closed parsing, calibrated-confidence routing, and a zero-config local heuristic fallback when no API key is set. Distinct from Node jev-shield (MCP/Gateway firewall).
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 →
