shellguard vs retyc-cli

shellguard: ShellGuard is an MCP server that provides LLM agents with controlled, read-only bash access to remote servers over SSH. It parses and validates every command against an allowlist, blocking destructive operations with helpful suggestions. The LLM can connect, run diagnostics, inspect logs, query databases, and download files without manual context-switching.; retyc-cli: Retyc CLI is the official command-line interface for Retyc, a European sovereign file-sharing platform with end-to-end post-quantum encryption. It allows you to send transfers and manage datarooms directly from your terminal, and also runs as a local MCP server to let AI agents control Retyc in plain language.
