The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
close-session ~87
Close a named session. A background session's command is signalled on the host (INT, then TERM, then KILL) before its channel is dropped; an interactive session's shell is ended. The response says so if the command could not be signalled or had not stopped in time.
| Name | Type | Req | Description |
|---|---|---|---|
| name | string | yes | Session name to close |
| profile | string | – | Profile name |
No output schema declared.
No examples provided.
list-connections ~29
List all configured SSH profiles and their connection status. Use this to discover available hosts before running commands.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
list-sessions ~32
List active sessions for a given SSH profile.
| Name | Type | Req | Description |
|---|---|---|---|
| profile | string | – | Profile name (uses default if omitted) |
No output schema declared.
No examples provided.
open-session ~99
Open a named session on a remote host. Use type="interactive" for stateful shell (CWD/env persists between commands) or type="background" for long-running processes.
| Name | Type | Req | Description |
|---|---|---|---|
| command | string | – | Command for background sessions |
| name | string | yes | Session name (alphanumeric, dash, underscore, max 64 chars) |
| profile | string | – | Profile name (uses default if omitted) |
| type | string | – | Session type |
No output schema declared.
No examples provided.
privileged-command ~106
Execute a command with sudo elevation. Goes through the approval gate; approvalPolicy on the profile decides whether that is a prompt, an automatic allow, or a refusal. The sudo password is piped via stdin (never visible in process list). Single-line only: a command containing a line break is refused, so upload a multi-line script with sftp-upload and run it by path.
| Name | Type | Req | Description |
|---|---|---|---|
| command | string | yes | Command to execute with sudo |
| profile | string | – | Profile name |
No output schema declared.
No examples provided.
read-command ~105
Execute a READ-ONLY command from an allowlist (ls, cat, grep, find, stat, df, etc.). This tool does NOT modify the system. Prefer this tool for all read operations. Single-line only: a command containing a line break is refused, so upload a multi-line script with sftp-upload and run it by path.
| Name | Type | Req | Description |
|---|---|---|---|
| command | string | yes | Read-only shell command (must be in the allowlist) |
| profile | string | – | Profile name |
No output schema declared.
No examples provided.
read-session-output ~57
Read recent output from a background session (e.g., tail -f logs).
| Name | Type | Req | Description |
|---|---|---|---|
| lines | number | – | Number of recent lines to read |
| name | string | yes | Background session name |
| profile | string | – | Profile name |
No output schema declared.
No examples provided.
run-command ~130
Execute an arbitrary shell command on the remote server. May modify the system. Commands classified destructive or privileged go through the approval gate; approvalPolicy on the profile decides whether that is a prompt, an automatic allow, or a refusal. Single-line only: a command containing a line break is refused, so upload a multi-line script with sftp-upload and run it by path.
| Name | Type | Req | Description |
|---|---|---|---|
| command | string | yes | Shell command to execute |
| profile | string | – | Profile name |
| session | string | – | Run in an existing interactive session (stateful) |
| tty | boolean | – | Allocate a pseudo-terminal |
No output schema declared.
No examples provided.
sftp-download ~42
Download a file from the remote server via SFTP.
| Name | Type | Req | Description |

No output schema declared.
No examples provided.
sftp-download-file ~122
Download a remote file to local disk over SFTP, streaming it without passing the contents through model context. The destination must be inside the transferRoot directory the operator configured; without that setting this tool refuses. Use this for binary or large files; use sftp-download when you need to read the contents.
| Name | Type | Req | Description |
|---|---|---|---|
| localPath | string | yes | Local destination, inside defaults.transferRoot |
| overwrite | boolean | – | Replace an existing local file (default false) |

| profile | string | – | Profile name |
| remotePath | string | yes | Remote directory to list |
No output schema declared.
No examples provided.
sftp-upload ~59
Upload a file to the remote server via SFTP (secure file transfer, not shell-based).
| Name | Type | Req | Description |
|---|---|---|---|
| content | string | yes | File content to upload |
| profile | string | – | Profile name |
| remotePath | string | yes | Remote file path |
No output schema declared.
No examples provided.
sftp-upload-file ~185
Upload a local file to the remote host over SFTP, streaming it without passing the contents through model context.
