mcp-firewall: A better policy-engine for CLI agents
Summary
MCP-FIREWALL is a policy-engine README describing a tool that sits between CLI agents and their tool requests, enabling regex-based, per-folder/policy enforcement. It supports Claude Code and GitHub Copilot CLI via pretool-use hooks and uses jsonnet to write shared rules, with installation options including binaries, nix, and flake, making it relevant for AI-assisted workflows and SMB security automation.
