actiongate-jev

Runtime authorization and guardrails for AI-agent tool calls with deterministic policy and TypeSafe Jev via OpenRouter.

Open-source Jev tool-calling authorization gateway for AI agents: deterministic policy, exact-action single-use permits, MCP and HTTP enforcement.

How it uses Jev

Open-source tool-calling authorization for AI agents. ActionGate is a runtime security gateway that evaluates a proposed tool call with deterministic policy plus TypeSafe Jev, called directly through TypeSafe or through OpenRouter, or experimental NVIDIA Nemotron evidence, binds approval to that exact action, and refuses expired, changed, or replayed permits.

Getting started

Node.js 22+ and pnpm 10+. No model key needed — it starts with a deterministic fake provider.
