Blocks rm -rf before your AI agent can run it
gate.cat is an innovative security tool designed to safeguard AI coding agents from executing destructive commands such as 'rm -rf', 'DROP TABLE', or 'terraform destroy'. It acts as a deterministic, fail-closed veto system that inspects outgoing tool calls at the boundary, preventing irreversible actions before they occur. Its versatile integrations include Claude Code hooks, gated shell environments, and OpenAI-API proxies, making it highly adaptable for various AI development workflows. What sets gate.cat apart is its thorough validation process, having replayed over a million real agent commands with zero misses, and its transparency through publishing bypass maps that demonstrate its security coverage. The tool is open source under the Apache 2.0 license and is free forever, making it accessible to developers and organizations seeking to enhance AI safety and control while maintaining flexibility in their automation processes.
Pros
- Robust veto mechanism that prevents dangerous commands from executing
- Open source with transparent security validation and bypass maps
- Easy integration with popular AI tools like Claude and OpenAI APIs
- Free forever, reducing barriers for adoption
- Deterministic and fail-closed design enhances safety
Cons
- May require configuration and tuning for specific workflows
- Limited to command filtering; does not prevent all types of malicious activity
- Potential false positives if not properly calibrated
Best for
- • Securing AI code generation environments from executing destructive commands
- • Preventing accidental data loss during AI-driven automation
- • Enhancing safety controls in AI-powered DevOps pipelines
- • Monitoring and vetoing harmful commands in sandboxed AI testing setups
Pricing: Gate.cat is open source and free forever, making it accessible without any direct cost. Its deployment and integration may incur operational costs depending on the environment and scale, but the tool itself does not require paid plans.
