How do I use Parallels RAS MCP Server?

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@Parallels RAS MCP Server Check the current license status and seat usage" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

Parallels RAS MCP Server

A lightweight, read-only Model Context Protocol (MCP) server for querying Parallels Remote Application Server (RAS) infrastructure via the RAS REST API v20.

Gives AI assistants read-only visibility into your RAS environment — infrastructure, site settings, policies, publishing, sessions, and support — without making any changes.

Prerequisites

Node.js 18 or later
npm
Access to a Parallels RAS server with the REST API enabled (port 20443)

Installation

git clone https://github.com/RMITBLOG/ParallelsRAS_MCP.git
cd ParallelsRAS_MCP
npm install
npm run build

Environment Variables

Variable	Required	Default	Description
`RAS_HOST`	Yes	—	RAS server hostname or IP address
`RAS_USERNAME`	Yes	—	Administrator username
`RAS_PASSWORD`	Yes	—	Administrator password
`RAS_PORT`	No	`20443`	REST API port
`RAS_IGNORE_TLS`	No	`true`	Skip TLS certificate verification (for self-signed certs)

Configuration

Claude Desktop

Edit your claude_desktop_config.json (typically at %APPDATA%\Claude\claude_desktop_config.json on Windows or ~/Library/Application Support/Claude/claude_desktop_config.json on macOS):

{
  "mcpServers": {
    "parallels-ras": {
      "command": "node",
      "args": ["/path/to/RAS_MCP/build/index.js"],
      "env": {
        "RAS_HOST": "ras-server.example.com",
        "RAS_USERNAME": "administrator",
        "RAS_PASSWORD": "your-password",
        "RAS_PORT": "20443",
        "RAS_IGNORE_TLS": "true"
      }
    }
  }
}

Claude Code

Add the MCP server to your project or global settings:

claude mcp add parallels-ras -- node /path/to/RAS_MCP/build/index.js

Set environment variables in your shell or in the Claude Code MCP configuration.

Cursor

In Cursor settings, go to Features > MCP Servers and add a new server:

Name: parallels-ras
Command: node /path/to/RAS_MCP/build/index.js
Environment Variables:
- RAS_HOST = ras-server.example.com
- RAS_USERNAME = administrator
- RAS_PASSWORD = your-password

OpenAI-Compatible Clients

For clients supporting the MCP standard via stdio transport, configure the server command as:

node /path/to/RAS_MCP/build/index.js

With the required environment variables (RAS_HOST, RAS_USERNAME, RAS_PASSWORD) set in the client's MCP server configuration.

Extending

To add a new tool module:

Create a new file in src/tools/ (e.g., notifications.ts)
Export a register(server: McpServer): void function
Use rasClient.get("/api/...") to call RAS endpoints
Import and call your register function in src/index.ts
Rebuild: npm run build

See existing tool files for the pattern.
