Zen vs railguard
Zen is an MCP server published by BeehiveInnovations. Marketplaces we read that list it: 1 (Docker MCP Catalog). railguard is a plugin bundle for AI coding tools published by railyard-dev. Marketplaces we read that list it: 1 (Claude Code: claude-plugins-community). As of our marketplace pass on 2026-10-13. This pair was picked by a reader, not by our comparison rule, so search engines are asked not to index the page.

Lines where the two differ have a tinted background and bold values. Where the data itself says which value is better (more marketplaces, a larger figure of the same marketplace, a fresher release, a verified mark on a marketplace that lists both), the better one is also marked green with ▲ and the worse one red with ▼. Where it runs, the transport, the tools, the settings, hooks, the bundle's parts, the licence and the week's changes are marked only as different: more or fewer is not better in itself.
What each says it does
Zen
Bridges multiple AI models and CLIs, enabling orchestrated workflows across Claude Code, Gemini CLI, Codex CLI, and other AI development tools.
railguard
Railguard is a safer, context-aware alternative to --dangerously-skip-permissions for Claude Code. Instead of choosing between approving every command manually or giving Claude unrestricted access, Railguard sits in the middle. It intercepts every tool call — Bash, Write, Edit, Read — and makes policy-based decisions: allow safe commands instantly, block dangerous ones automatically, and ask for human approval when it's not sure. Out of the box, Railguard comes with 29 default rules covering destructive operations like terraform destroy, rm -rf, DROP TABLE, and git force-push. It detects evasion attempts (base64 encoding, chr construction, variable substitution, shell wrapping), restricts file access with path fencing (blocking ~/.ssh, ~/.aws, /etc), snapshots every file write for one-click rollback, and logs every decision to a structured audit trail. Everything is customizable through a simple railguard.yaml file in your project directory.
