HOL GuardMaker

AI coding agents such as Claude Code, Codex and Cursor can run commands, read files and install dependencies on your behalf. HOL Guard adds a local checkpoint in front of those actions: shell commands, secret-file reads, MCP tool calls and package installs are evaluated on your machine first, routine work continues, and risky actions wait for you to allow or block them. Decisions are kept in a local log.

For developers and teams using AI coding agents. The core is open source under Apache-2.0; optional Guard Cloud is available for teams. HOL Guard is not a gateway or network firewall and does not claim to block every prompt injection; scans are not a safety guarantee.

Get started: pipx install hol-guard && hol-guard init
