Runs a shell command over SSH on a named configured server and returns stdout, stderr, and exit code. Mutates remote state depending on the command; not read-only. Expands command aliases before running. Uses the cwd parameter or, if omitted, the server configured default directory; adapts syntax for Linux versus Windows PowerShell targets. Timeout defaults to 120000 ms and is capped at 300000 ms. Under readonly mode destructive commands like rm or dd are refused; under restricted mode the command must match allow patterns. Output is truncated when very large.

Uploads one local file to a remote destination path over SFTP on the named server, overwriting any existing remote file at that path. Mutates remote state and is not idempotent beyond replacing the target. Creates no backup. Requires the local file to exist. Does not use sudo, so the remote path must be writable by the configured SSH user. This tool is blocked entirely on servers set to readonly or restricted security mode. For directory trees use ssh_sync instead.

Downloads one remote file from the named server to a local destination path over SFTP, overwriting any existing local file at that path. Affects only the local filesystem and is read-only on the remote side, so it stays allowed even on servers in readonly or restricted security mode. Reads the remote file using the configured SSH user, which must have permission to read it. Handles single files only; use ssh_sync for directories.

Runs one command on every server belonging to the named group and returns a per-server success or failure report. Mutates remote state on each member and is not idempotent. Best-effort: the security policy of each server is evaluated independently, so readonly or restricted members are reported as failed without aborting the rest unless stopOnError is set. Strategy may be parallel, sequential, or rolling (delay applies between servers). Per-server timeout is 30000 ms; cwd defaults to the configured default directory.

Lists all SSH servers defined in the loaded configuration, returning for each the name, host, user, port, authentication type (password or key), default directory, and description. Read-only and local: it reads configuration only and opens no SSH connections. Deliberately omits secrets, so no passwords, key paths, passphrases, or sudo passwords are returned. Takes no parameters. Useful as a first call to discover which server names other tools accept.

Deploys a list of local files to remote paths on the named server, uploading each to a temporary location first and then moving it into place. Mutates remote state. By default it backs up any existing target file before overwriting; backup can be disabled per call. Options can set owner and permissions, supply a sudo password, and name a single service to restart afterward. Detects sensible owner and permission defaults from the remote path. Runs pre and post deploy hooks. Blocked entirely on servers in readonly or restricted security mode.

Opens a new SSH connection to the named server and starts a port-forwarding or SOCKS proxy tunnel that keeps running until closed. The type parameter selects local forward, remote forward, or dynamic SOCKS5 proxy. localPort is always required; remoteHost and remotePort are required for local and remote types but ignored for dynamic. localHost defaults to 127.0.0.1. Returns a tunnel ID used later to close it.

Lists currently active SSH tunnels tracked by this process, showing each tunnel ID, server, type, state, local and remote endpoints, active and total connection counts, bytes transferred, error count, and timestamps. Read-only: it does not create, modify, or close anything. The optional server parameter filters results to one server; omit it to list every active tunnel across all servers.

Tears down active SSH tunnels created earlier, freeing the bound local ports; this affects only local tunnel state, not the remote host. Exactly one of tunnelId or server must be supplied: tunnelId closes that single tunnel, while server closes every tunnel for the named server and reports how many were closed. Supplying neither raises an error. Closing is final and cannot be undone.

Manages SSH host key fingerprints in your local known_hosts file for the named server. The action parameter selects: verify, check, and list are read-only comparisons or listings; accept adds or updates the host key in known_hosts; remove deletes it. accept and remove mutate local state and are blocked on servers configured as readonly. server is required for every action except list. autoAccept defaults to false and should be used with caution.

Creates a database or file backup on the remote server over SSH, writing a compressed archive plus a JSON metadata file into backupDir. Supports mysql, postgresql, mongodb, and files (full is not yet implemented and errors). Database types require database; files requires paths. After writing it prunes backups older than retention days (default 7); compress defaults to true. Runs pre-backup and post-backup hooks.

Lists existing backups found in backupDir on the remote server, returning each backup id, type, database or paths, size, compression, retention, status, and creation time parsed from stored metadata. Read-only: it inspects the filesystem and mutates nothing. Optional type filters results to mysql, postgresql, mongodb, files, or full. backupDir defaults to the configured backup directory.

Restores a previously created backup identified by backupId, reading its metadata to pick the engine. This is destructive and overwrites the target: PostgreSQL runs pg_restore with --clean --if-exists which DROPs existing objects, MongoDB runs mongorestore --drop, and MySQL pipes the dump into the live database replacing matching objects. Supports mysql, postgresql, mongodb, and files. Runs pre-restore and post-restore hooks.

Schedules a recurring backup on the remote server by writing an executable bash script to /usr/local/bin/ssh-manager-backup-NAME.sh and installing a crontab entry for the given cron expression. Mutates the remote filesystem and crontab, and typically needs root to write that path. Supports mysql, postgresql, mongodb, and files; the generated script also deletes backups older than retention days (default 7).

Runs a comprehensive read-only health check on the named server by executing diagnostic shell commands over SSH, then returns parsed JSON with overall status, CPU, memory, disk usage, and uptime. It only reads metrics and changes nothing on the remote host. Set detailed to true to additionally include load average and network metrics; it defaults to false. Critical CPU, memory, or disk conditions are surfaced in a critical_issues list.

Checks the running state of the named system services on a remote server by querying each one over SSH, returning JSON per service plus running and stopped counts and an aggregate health rating. Read-only: it inspects status without starting, stopping, or restarting anything. The services array parameter is required and lists the service names to check, for example nginx, mysql, or docker; common names are resolved to their actual unit names automatically.

Lists, inspects, or terminates processes on a remote server over SSH. The action parameter selects: list returns top processes (read-only), info returns details for one process (read-only), and kill sends a signal to terminate a process and mutates remote state. pid is required for kill and info. kill is blocked on servers configured as readonly. signal defaults to TERM, sortBy defaults to cpu, and limit defaults to 20; filter narrows the list by name or command.
