HOL Guard — AI for Software Development

When you use AI coding agents to write code, execute shell commands, or interact with databases, you run the risk of the model executing unintended or destructive actions, such as wiping directories or exposing cloud credentials. HOL Guard acts as an explicit checkpoint sitting directly between your coding agent and your local machine. Because it operates locally, your source files and code never have to leave your computer for inspection. You can configure it to intercept shell commands, package installations, secret accesses, and Model Context Protocol (MCP) tool calls. When a risky command is evaluated, Guard intercepts it and prompts you to allow or block the action based on your established policy rules. The free local version operates entirely offline with zero account requirements, giving you basic runtime protection out of the box. If you work across multiple machines or manage developers on a shared project, you can opt into paid cloud tiers like Solo, Pro, or Team. These optional upgrades provide synced approval histories, audit logs, automated alerts, policy versioning, and centralized team dashboards. While local scanning provides immediate runtime safety, it is important to note that a scan is not an absolute safety guarantee against all sophisticated exploits. However, for developers looking to maintain granular control over what autonomous tools can touch on their local file systems, HOL Guard provides a transparent, open-source safety floor that catches mistakes before they turn into major repository or infrastructure failures.
