By default OpenSnitch UI listens on a local Unix socket in /tmp/osui.sock.

    AgentGuard

    AgentGuard

    AgentGuard is a firewall for AI agents

    ...It works by intercepting API calls made by an AI system and continuously monitoring usage, including token consumption and associated costs, allowing developers to enforce strict budget limits.
