Built around the daily loop of server work.

Connect, forward, transfer, automate. One tool instead of six.

SSH connections

Multi-level jump hosts, live status and one-click reachability tests.

Port-forwarding tunnels

Local, remote and dynamic SOCKS tunnels with health checks.

Keys and users

RSA and ECC keys, encrypted imports, roles per user.

SFTP

Dual-pane transfers and cross-session file copy.

Terminal

Multi-tab sessions, split panes and in-buffer search.

Task automation

Scheduled jobs with conditions, loops and pipelines.

AI assist

Generate scripts, read logs and run agent tasks under permissions you set.

  • Generate and edit scripts from a plain-language request
  • Explain log output and failed commands
  • Run multi-step agent tasks, approving each write

MCP server

Expose your hosts to Cursor, Claude Code and other agents as callable tools.

claude mcp add --transport http sts \
  http://127.0.0.1:8765/mcp

opencode mcp add   # Remote -> http://127.0.0.1:8765/mcp

The same tool from the command line

Every connection, tunnel and task is reachable headlessly with --json output, so scripts and agents can drive them too.

$ sts.exe ssh list
ID  NAME      HOST         PORT  STATUS
1   prod-web  192.168.1.1  22    active
2   dev       10.0.0.5     22    active

Every screen, no surprises.

Connections, tunnels, keys, scripts and tasks are all managed in one place.
