AgentGuard – fail-closed approval gateway for AI agent tool calls
AgentGuard A fail-closed approval gateway for AI agent tool calls. If your agent can call tools that do real things (delete data, send payments, revoke access, hit an API with side effects), you eventually want a layer that pauses risky calls until a human approves them -- and denies by default if nothing approves it. This repo is a minimal, dependency-free demo of that gateway.

If your agent can call tools that do real things (delete data, send payments, revoke access, hit an API with side effects), you eventually want a layer that pauses risky calls until a human approves them -- and denies by default if nothing approves it. Not "log and hope." Actually blocked. This repo is a minimal, dependency-free demo of that gateway. It's not a full SDK integration yet -- it's the core logic, extracted from a script I run internally, packaged so you can see exactly how it behaves. How it works SAFE_TOOLS -- whitelisted, auto-approved, no human needed. DESTRUCTIVE_TOOLS -- always requires explicit human approval before running.
