Ssh

Persistent interactive SSH sessions, profiles, PTY shells, SFTP/SCP file transfers, and remote background job supervision for Claude Code, OpenCode, and MCP clients.

Dual-compatible as an OpenCode Plugin and a standalone Model Context Protocol (MCP) Server.

---

Features

• Persistent SSH Sessions: Reuses open connections in memory without repeating handshakes.
• PTY Shell & Multiplexed Exec: Run single discrete commands or maintain state across commands in a persistent shell.
• SFTP & High-Speed SCP: Read, write, targeted find-and-replace, and chunked recursive local-remote or remote-to-remote file transfers.
• Claude Code & MCP Native: Works out-of-the-box with Claude Code (claude mcp add), Cursor, Claude Desktop, and OpenCode.
• Pager Guard: Automatically sets TERM=dumb, PAGER=cat, and CI=1 to prevent interactive hangs.
• Key & Passphrase Support: Reads private keys from disk or options, supporting passphrases and environment variables.
• Detached Background Jobs: Spawn, inspect, fetch logs, and terminate long-running remote processes.
• Cluster Broadcast: Execute commands across multiple active sessions concurrently.
• System Diagnostics: Single-call probe gathering OS, hardware, runtime, and network info.

Usage with Claude Code

Option 1: Quick Add via CLI (Recommended)

Run directly in your terminal:

claude mcp add ssh -- npx -y opencode-plugin-ssh

Option 2: Project .mcp.json

Add a .mcp.json file in your repository root:

{
  "mcpServers": {
    "ssh": {
      "command": "npx",
      "args": ["-y", "opencode-plugin-ssh"]
    }
  }
}

Option 3: Claude Code Plugin & Mod (Slash Commands + Live Spinner)

Install directly into Claude Code:

claude plugin add opencode-ssh

Or load locally during development:

claude --plugin-dir /path/to/opencode-ssh

When loaded as a Claude Code plugin/mod, it automatically adds:

• /ssh-profiles: Browse configured hosts and connection parameters from ~/.ssh/config.
• /ssh-status: View real-time active SSH tool operations and history.
• /ssh-help: Instant cheatsheet of available SSH commands and MCP tools.
• Live Spinner Feedback: Shows · SSH: <operation> on the Claude Code spinner whenever a remote SSH or SCP task is running.

---

Usage with OpenCode

Add to your OpenCode configuration (opencode.json or ~/.config/opencode/opencode.jsonc):

{
  "plugin": [
    "opencode-plugin-ssh"
  ]
}

Or install as a local dependency:

npm install -D opencode-plugin-ssh

---

Usage with Claude Desktop / Cursor / Other MCP Clients

Add to your claude_desktop_config.json or Cursor MCP configuration:

{
  "mcpServers": {
    "ssh": {
      "command": "npx",
      "args": ["-y", "opencode-plugin-ssh"]
    }
  }
}

Tools

All tools are available across both OpenCode and MCP clients:

Sessions & Connections

• ssh_list_profiles: List profiles from ~/.ssh/config and saved configurations.
• ssh_save_profile: Store host connection parameters for quick reuse.
• ssh_connect: Open or verify an active SSH session.
• ssh_list_sessions: List connected sessions and their active status.
• ssh_switch_session: Change the default active session.
• ssh_close: Disconnect and clean up a session.
• ssh_broadcast: Run a command across multiple connected sessions.

Execution & PTY

• ssh_exec: Run a non-interactive command and return stdout, stderr, exit code, and executedAs.
• ssh_interactive_cmd: Execute commands inside a persistent PTY shell (returns output and executedAs).
• ssh_switch_user: Switch user (e.g. to root) in the persistent shell via sudo/su with automatic password handling.
• ssh_pty_send: Send raw text or control characters (e.g. \x03) to the PTY.
• ssh_pty_read: Retrieve recent buffer output from the PTY shell.

Filesystem (SFTP & SCP)

• ssh_scp: Securely copy files or directories between local machine and remote host (upload / download), or stream directly between two remote sessions (remote_to_remote) with recursive and chunked transfer support.
• ssh_read_file: Read remote files with pagination and line numbering.
• ssh_write_file: Write or overwrite remote files over SFTP.
• ssh_edit_file: Find and replace exact substrings within remote files.
• ssh_list_dir: Structured directory listing (name, size, mode, permissions, isDirectory, isSymlink, mtime).
• ssh_stat: Inspect file/directory metadata or test for existence (size, permissions, timestamps, link targets).
• ssh_mkdir: Create remote directory with optional recursive creation of parent directories (-p).
• ssh_rm: Delete a remote file or folder with optional recursive directory removal.
• ssh_rename: Move or rename remote files and directories over SFTP.
• ssh_chmod: Change remote file/directory permissions via octal mode (e.g. '0755', '0644', '0600').

Background Jobs & Health

• ssh_system_inspect: Inspect system metrics, listening ports, and installed runtimes.
• ssh_job_spawn: Start a supervised background job.
• ssh_job_status: Check status and exit code of a spawned job.
• ssh_job_logs: Fetch stdout and stderr output from a background job.
• ssh_job_kill: Terminate a background job with a specified signal.
