shellguard vs chiasmus

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.; chiasmus: Chiasmus is an MCP server that integrates formal verification (Z3, Prolog) and code analysis (tree-sitter) to solve complex logical and structural problems. It translates natural language into formal logic using templates and provides verified results. It also analyzes source code call graphs for dead code, impact, and reachability.
