    What is HOL Guard?

    HOL Guard is a local-first control point for AI coding agents. It reviews shell, secrets, MCP, and package-install calls before they hit the OS. Open source (Apache-2.0). pipx install hol-guard && hol-guard init. Scan is not a safety guarantee. Maker: HOL.

    What it solves
    • AI agents can trigger risky shell or system changes
    • Teams need checks before tool calls reach the OS
    • Cloud-only filters can miss activity on a developer laptop
    How it works
    • Runs locally as a control point for agent tool calls
    • Reviews shell, secrets, MCP, and install calls before the OS
    • Uses an Apache-2.0 open-source local workflow
