Setting up with Highlight
This MCP is not yet compatible with Highlight’s one-click setup. However, you can still use it with Highlight by following these steps:
- Download and install Highlight from highlightai.com/download
- Navigate to the plugins tab and select "Add Custom Plugin"
-
Configure the plugin with the settings below
Plugin Name
SSH MCP ServerCommand (node, npx, python, etc.)Please refer to the README for specific instructions on how to obtain API keys or other required environment variables.
- Enable "Start Automatically" if you want the plugin to start when Highlight launches
list_servers
List all configured servers and active connections
get_server
View server configuration details
connect
Manually connect to server (usually not needed, tools auto-connect)

execute
Execute shell command on remote server
write_file
Write content to remote file (overwrite)

Let AI manage your remote servers.A Model Context Protocol (MCP) server that gives AI assistants full SSH access — execute commands, transfer files, manage multiple servers simultaneously, all through natural conversation.
You: "Deploy the latest build to production server" AI: connects → uploads build → restarts service → verifies status
- 21 Tools— Connect, execute, upload, download, write files, and more
- Connection Pool— Operate multiple servers simultaneously, each command tagged withserver_id
- Zero-Token File Transfer— SFTP path-based transfer, file content never enters AI context
- Directory Upload— Auto tar.gz compress → upload → remote decompress (fast for many small files)
- Async Transfer + Progress— Background transfer for large files with real-time progress tracking
- Quick Connect— Temporary connections without saving config, returnshost:portas temp ID
- SOCKS4/5 Proxy— Per-connection proxy support
- Jump Host— SSH ProxyJump for bastion/gateway access
- Multi-Auth— Password, private key, ssh-agent, keyboard-interactive (OTP/2FA)

Connection Pool: Multi-Server Operations
All operation tools take aserver_idparameter. The connection pool auto-manages connections — no manual connect/disconnect needed:
AI: execute(server_id="prod", command="nginx -s reload") ← auto-connects to prod AI: execute(server_id="dev", command="tail -f /var/log/app.log") ← auto-connects to dev, prod stays AI: execute(server_id="prod", command="curl localhost") ← reuses prod connection
For temporary servers, usequick_connectwhich returnshost:portas the ID:
AI: quick_connect(host="1.2.3.4", username="root", password="") → "Connected: [email protected]:22, use server_id="1.2.3.4:22"" AI: execute(server_id="1.2.3.4:22", command="df -h") AI: disconnect(server_id="1.2.3.4:22")
For large files, enable background transfer mode to avoid blocking:
AI: upload_file(server_id="prod", local_path="big.tar.gz", remote_path="/data/", async_transfer=true) → "Background upload started: tf_1" AI: transfer_status("tf_1") → "🔄 Uploading: 638.2 MB / 1.2 GB (53.2%) — 12.4 MB/s, ETA 46s" AI: transfer_status("tf_1") → "✅ Upload complete: 1.2 GB, 98s, 12.3 MB/s"
Small files use synchronous mode by default — no config needed.
AI: add_server(server_id="prod", name="Production", host="10.0.0.1", username="deploy", password="") AI: execute(server_id="prod", command="systemctl status nginx")
AI: add_server(server_id="aws", name="AWS EC2", host="ec2-xx.compute.amazonaws.com", username="ubuntu", private_key="~/.ssh/id_rsa")
AI: quick_connect(host="192.168.1.100", username="root", password="") → server_id="192.168.1.100:22" AI: execute(server_id="192.168.1.100:22", command="df -h") AI: disconnect(server_id="192.168.1.100:22")
AI: add_proxy(proxy_id="tunnel", name="SSH Tunnel", host="127.0.0.1", port=1080, type="5") AI: add_server(server_id="internal", ..., proxy="tunnel")
AI: add_server(server_id="bastion", name="Bastion", host="bastion.example.com", username="admin", private_key="~/.ssh/id_rsa") AI: add_server(server_id="internal", name="Internal DB", host="10.0.0.5", username="dbadmin", password="", jump_host="bastion")
Server and proxy configurations are stored in:
Passwords are stored in plaintext. For production use, prefer private key authentication.
