Developer note
Built because we wanted a yes/no moment before an agent runs something we cannot take back.
About HOL Guard
Coding agents move fast, and some of what they do is hard to undo: a destructive shell command, a read of your .env, a surprise package install, an MCP tool call you didn't expect.
HOL Guard runs on your own computer alongside Claude Code, Codex and Cursor. Those actions stop and wait; you look at what the agent wants and approve or block it.
- Holds risky shell commands, secret file reads, MCP tool calls and package installs for your decision
- Local-first: the checks run on your machine
- Free and open source (Apache-2.0)
- Guard Cloud is an optional paid add-on (Solo from $4.99/mo)
Get started:
pipx install hol-guard && hol-guard init
What it isn't: a gateway, a network firewall, or a full fix for prompt injection, and a scan is not a safety guarantee.
