    }
  }
}

Run this in your terminal

claude mcp add safe-ssh -- uvx safe-ssh-mcp

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{

    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "safe-ssh": {
      "type": "stdio",
      "command": "uvx",
      "args": [
        "safe-ssh-mcp"

    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Common questions

Is Safe Ssh MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.15) reached the registry 3 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.

What can I use instead?

Safe SSH MCP Server

A secure and scoped SSH MCP server for executing read-only diagnostic commands over SSH. In this project, "safe" refers specifically to host safety: the server is designed to prevent modifications to the remote system and reduce the risk of operational harm. It does NOT attempt to guarantee that command output cannot be misused by external agents.

Badges

security check

Overview

The core philosophy behind this MCP server is safety first. Instead of providing an AI agent with an unrestricted bash shell, this server exposes only carefully curated, read-only commands for system diagnostics and monitoring.

Example of invocation

okay, could u check disk usage on /root/ path with help of safe-ssh-mcp server on a remote myserver.mydomain.pro using root and /Users/myUser/.ssh/id_rsa to login?

Means of connection

The server supports SSH account-password authentication and private-key authentication. Configure the private-key passphrase source in mcp_config.ini:

# ENV_VAR (SSH_KEY_PASSPHRASE) or KEYCHAIN (ssh-agent)

ssh_key_passphrase_method=ENV_VAR

SSH account password: provide password to the MCP tool. Do not use this for a private-key passphrase.
Unprotected SSH key: use key_path. The default ENV_VAR setting also supports unprotected keys; SSH_KEY_PASSPHRASE is not required.
Passphrase-protected SSH key from an environment variable: leave ssh_key_passphrase_method=ENV_VAR, set SSH_KEY_PASSPHRASE in the environment that starts the MCP server, and provide key_path.

   export SSH_KEY_PASSPHRASE='your-key-passphrase'

safe-ssh-mcp

macOS Keychain / SSH agent: set ssh_key_passphrase_method=KEYCHAIN, then unlock the key in the same user session that starts the MCP server. The server receives SSH signatures from ssh-agent; it does not read the key passphrase or the key_path.

   ssh-add --apple-use-keychain ~/.ssh/id_ed25519

Optional: make the loaded identity expire after one hour.

ssh-add -t 1h ~/.ssh/id_ed25519

Remove one identity, or clear every loaded identity.

ssh-add -d ~/.ssh/id_ed25519 ssh-add -D

Cursor launched from the macOS Dock: use KEYCHAIN (recommended). You can run ssh-add from any Terminal window; it updates the SSH agent for your macOS login session, so Cursor does not need to be started from that Terminal.

   ssh-add --apple-use-keychain ~/.ssh/id_ed25519

ssh-add -l

After changing mcp_config.ini, restart the MCP server in Cursor (or fully quit and reopen Cursor). When invoking a tool in KEYCHAIN mode, omit key_path; the agent selects from its loaded identities.

If you must use ENV_VAR, set it in the macOS launchd session before opening Cursor from the Dock, then fully quit and reopen Cursor:

   launchctl setenv SSH_KEY_PASSPHRASE 'your-key-passphrase'

This value lasts only for the current login session, and putting a passphrase directly in a command may save it in shell history. Prefer KEYCHAIN.

For KEYCHAIN, the MCP server must inherit SSH_AUTH_SOCK from that user session. This is normally automatic for a stdio server started from a desktop application. ENV_VAR stores the passphrase in the server process environment, so restrict access to the process and avoid putting it in source control.

This project is licensed under the GNU AGPLv3 License.

Why AGPL?

This server acts as core infrastructure and contains no business logic. By using the AGPL license, we ensure that any security improvements, bug fixes, or new diagnostic tools added to the server are shared back with the open-source community.

Note for Client Developers

Because MCP clients communicate with this server via standard Inter-Process Communication (IPC) or network protocols (like HTTP/SSE), the AGPL license does not "infect" or restrict the client applications connecting to it. You can safely connect proprietary, closed-source, or permissively licensed (e.g., MIT, Apache 2.0) AI agents to this server without violating the license terms.
