Sits between your AI agent and the outside world, catching risky actions — deleting a file, reading a credential, sending money — and holding them for a human to approve before they actually happen.
Best alternatives to HOL Guard in 2026
AI coding assistants like Claude Code, Cursor or GitHub Copilot CLI can now run shell commands, edit files and install packages on their own — which is powerful, but also means a bad suggestion, a prompt injection, or a hallucinated command can do real damage to your machine before you notice. HOL Guard installs like antivirus software for these agents: it sits locally on your computer and inspects every shell, file, MCP, skill and package action the agent tries to take, blocking the risky ones and asking for your approval on anything flagged. It's open source under the Apache 2.0 license, works locally by default with no cloud account required (cloud connectivity is optional), and supports over 13 AI agent platforms with desktop installers for macOS, Windows and Linux. Beyond blocking obviously unsafe commands, it detects secret exposure (accidentally printing an API key), flags prompt injection attempts, and scans installed packages and MCP servers for known-malicious supply-chain risks. Everything it catches is written to a local audit log that survives even if you uninstall the tool, so you keep a record of what your agents actually tried to do.
