Side-by-side comparison of two Model Context Protocol servers — install paths, tools, quality signals, and directory engagement so you can pick the right one for Claude, Cursor, and other MCP clients.
MCP server for SSH-based control of remote Linux, macOS, and Windows servers with 46 purpose-built tools instead of one generic command-runner: line-level file editing (no download/edit/upload round-trip), background task launch/monitor/kill, real sudo support, host aliases, recursive directory ops, archive create/extract, and full Unicode via SFTP (avoids PowerShell OEM code page corruption on Windows targets). pip install cygnus-ssh-mcp or uvx cygnus-ssh-mcp.
SSH & Kubernetes access broker where the model never touches a credential: a separate signer mints per-operation ephemeral SSH certificates and bound ServiceAccount tokens, with a per-command allow/deny/approval firewall (POSIX-sh AST), dry-run, human-in-the-loop approvals, session recording and an Ed25519-chained audit log. Self-hosted Go binaries, GPLv3.
