{
  "mcpServers": {
    "ssh": {
      "command": "node",
      "args": ["%APPDATA%/npm/node_modules/mcp-ssh/dist/server.js"],
      "env": {
        "SSH_PORT": "8889",
        "SSH_LOG_LEVEL": "info"
      }
    }
  }
}

Start the Server:
- Clone the repository and navigate to the directory.
- Install dependencies and build the server.
- Start the server.
Testing Connections: Use PowerShell or CLI tools to test different authentication methods, command execution, and file operations as described in the README.
