Establish an SSH connection to a remote host. Supports jump hosts (bastion) for connecting to internal networks. Returns a connectionId for subsequent operations.

Disconnect an existing SSH connection.

Execute a single command on a connected remote host. Returns stdout, stderr, and exit code.

Execute a multi-line bash script on a connected remote host. The script is passed via stdin to bash -s.

Read the contents of a file on a connected remote host via SFTP.

Write content to a file on a connected remote host via SFTP. Creates or overwrites the file.

List files and directories in a remote path via SFTP.

Upload a local file or directory to a connected remote host via SFTP. Automatically detects file vs directory. For directories, recursively uploads all contents.

Download a remote file or directory to the local machine via SFTP. Automatically detects file vs directory. For directories, recursively downloads all contents.

Show the status of all active SSH connections, including host, uptime, and command count.

Query the persistent operation log. Returns past SSH operations (connect, exec, sftp, etc.) for traceability. Useful for reviewing what was done on a server.

Query logs from a remote server. Supports file tailing, journalctl, and Docker container logs. Use follow=true to enable incremental tracking — subsequent calls return only NEW log lines (simulates tail -f).

Save an SSH host configuration for quick access. After saving, use ssh_connect with just the alias to connect without re-entering credentials.

Remove a saved SSH host configuration.

List all saved SSH host configurations. These can be used with ssh_connect by alias.

Update notes, description, or tags for a saved host. Use this to record findings, document issues, or enrich the host profile based on what you learn during operations. No credentials needed.
