NinjaOne MCP Server

A Model Context Protocol (MCP) server for the NinjaOne RMM platform. Gives Claude and other MCP clients direct access to your NinjaOne environment — query devices, manage alerts, run scripts, create tickets, and more.

Features

• 75 tools spanning all major NinjaOne API areas
• OAuth2 client_credentials authentication with automatic token refresh
• Pagination and device filter (df) support on all list endpoints
• Zero runtime dependencies beyond axios and the MCP SDK

Prerequisites

• Node.js 18 or later
• A NinjaOne account with API access
• OAuth2 API credentials (see Obtaining Credentials)

Obtaining Credentials

1. Log in to your NinjaOne portal and go to Administration → Apps → API
2. Click Add to create a new API application
3. Select Client Credentials as the authorization flow
4. Grant the scopes your use case requires:
   • monitoring — read-only device/alert data
   • management — manage devices, organizations, policies
   • control — run scripts, trigger patch jobs, reboot devices
5. Copy the Client ID and Client Secret — the secret is only shown once

Your instance base URL depends on your region:

Region	Base URL
US	https://app.ninjarmm.com
EU	https://eu.ninjarmm.com
OC	https://oc.ninjarmm.com
CA	https://ca.ninjarmm.com

Installation

Option 1 — Clone and build (recommended)

git clone https://github.com/Allied-Business-Solutions/ninjaone-mcp.git
cd ninjaone-mcp
npm install
npm run build

Option 2 — Run directly with tsx (dev/testing)

git clone https://github.com/Allied-Business-Solutions/ninjaone-mcp.git
cd ninjaone-mcp
npm install

Then use npm run dev instead of node dist/index.js in the config below.

Configuration

Environment Variables

Variable	Required	Description
NINJA_BASE_URL	Yes	NinjaOne instance URL (e.g. https://app.ninjarmm.com)
NINJA_CLIENT_ID	Yes	OAuth2 client ID from the NinjaOne Developer Portal
NINJA_CLIENT_SECRET	Yes	OAuth2 client secret from the NinjaOne Developer Portal

Create a .env file by copying the example:

cp .env.example .env
# then edit .env with your credentials

Claude Desktop

Add the following to your claude_desktop_config.json:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "ninjaone": {
      "command": "node",
      "args": ["/absolute/path/to/ninjaone-mcp/dist/index.js"],
      "env": {
        "NINJA_BASE_URL": "https://app.ninjarmm.com",
        "NINJA_CLIENT_ID": "your_client_id",
        "NINJA_CLIENT_SECRET": "your_client_secret"
      }
    }
  }
}

Restart Claude Desktop after saving.

Claude Code (CLI)

Add the server to your project or global MCP config:

claude mcp add ninjaone \
  -e NINJA_BASE_URL=https://app.ninjarmm.com \
  -e NINJA_CLIENT_ID=your_client_id \
  -e NINJA_CLIENT_SECRET=your_client_secret \
  -- node /absolute/path/to/ninjaone-mcp/dist/index.js

Other MCP Clients

The server uses stdio transport and follows the standard MCP protocol. Point any MCP-compatible client at node dist/index.js with the three environment variables set.

status = APPROVED                # Approved devices only
class in (WINDOWS_WORKSTATION, WINDOWS_SERVER)
