sigcli

Sigcli is a security-focused CLI and proxy tool that lets AI agents authenticate to services using short-lived, scoped tokens instead of sharing long-lived user credentials. It is designed for developers and teams deploying autonomous agents who need to grant granular, revocable access without exposing sensitive API keys or passwords. Its interesting because it solves the fundamental security challenge of credential delegation in agentic workflows, enabling safer automation and third-party integrations.
