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.
Interactive PTY sessions for AI agents — local shells, SSH with persistent sessions (ai-tmux daemon for attach/detach), and serial ports. Single Go binary, no tmux dependency.
