HOL Guard is a local-first security tool for AI coding agents that helps prevent risky actions before they affect your computer. It monitors agent activity and can pause or block potentially dangerous operations, including deleting files, accessing credentials and secrets, sending sensitive data, installing untrusted software, changing MCP configurations, and running high-risk shell commands. Users can review blocked actions, approve legitimate requests, and maintain control over how their AI assistant interacts with local files, tools, and development environments.

HOL Guard runs on the developer’s machine and can protect supported AI tools without requiring an internet connection. It is designed for use with Claude Code, Cursor, Codex, Gemini CLI, OpenCode, Hermes, and OpenClaw. The local protection layer supports policy enforcement and a decision history for approvals and changes, while the optional cloud layer adds shared policies, organization dashboards, synchronized settings, and activity visibility. HOL Guard also supports AI plugin and skill security workflows through scanning for suspicious commands, prompt injection markers, secret exposure, insecure MCP endpoints, and incomplete plugin metadata.
