NinjaOne MCP Server

A Model Context Protocol (MCP) server for interacting with NinjaOne, featuring a decision tree architecture for efficient tool loading.

One-Click Deployment

[!IMPORTANT] Before you click: this server depends on @wyre-ai/node-ninjaone, which is hosted on the GitHub Packages npm registry. GitHub Packages has no anonymous access — even though the package is public, every npm install needs a token. The cloud builder runs npm install for you, so you must give it one, or the build fails with npm error 401 Unauthorized ... npm.pkg.github.com.

1. Create a GitHub Personal Access Token with the read:packages scope (classic token). Any GitHub account works — you do not need to be a member of the wyre-ai org to read its public packages.
2. Add it as a build variable when prompted by the deploy flow:
   • Cloudflare Workers → set a build variable named NODE_AUTH_TOKEN to your PAT (Workers → Settings → Build → Variables and Secrets).
   • DigitalOcean App Platform → set an encrypted env var named GITHUB_TOKEN with scope Build Time to your PAT (the .do/app.yaml already declares it).

[!NOTE] Both targets run the full MCP server. DigitalOcean builds the Docker image and serves it over HTTP; Cloudflare Workers serves the same server via the SDK's Web Standard Streamable HTTP transport (src/worker.ts). After deploying, set your NinjaOne credentials as secrets — NINJAONE_CLIENT_ID, NINJAONE_CLIENT_SECRET, and optionally NINJAONE_REGION — or set AUTH_MODE=gateway to take credentials per-request from X-Ninja-* headers. The MCP endpoint is /mcp; /health is an unauthenticated liveness probe.

Architecture

This MCP server uses a hierarchical tool loading approach instead of exposing all tools upfront:

1. Navigation Phase: Initially exposes only a navigation tool (ninjaone_navigate)
2. Domain Selection: User selects a domain (devices, organizations, alerts, tickets)
3. Domain Tools: Server exposes domain-specific tools after selection
4. Lazy Loading: Domain handlers and the NinjaOne client are loaded on-demand

This architecture provides:

• Reduced cognitive load (fewer tools to choose from)
• Faster initial load times
• Better organization of related operations
• Clear navigation state

Installation

This package is published to the GitHub Packages npm registry, which requires a token even for public packages. Authenticate once, then install:

# Authenticate npm to GitHub Packages (token needs the read:packages scope)
export NODE_AUTH_TOKEN=$(gh auth token)   # or a PAT with read:packages

npm install @wyre-ai/ninjaone-mcp

The repo's .npmrc already points the @wyre-ai scope at GitHub Packages and reads the token from NODE_AUTH_TOKEN, so no further config is needed. The same applies to npx @wyre-ai/ninjaone-mcp below. Prefer a zero-setup option? Use the prebuilt container image (ghcr.io/wyre-ai/ninjaone-mcp) or the .mcpb bundle attached to each release.

Configuration

Set the following environment variables:

NinjaOne API Regions

Usage

Running Standalone

# Set credentials

Available Domains

Devices

Manage endpoints, reboot devices, view services and alerts.

Tools:

• ninjaone_devices_list - List devices, filterable by organization, device class, and online status. Paginated: a full page returns hasMore: true and a cursor to pass back for the next page.
• ninjaone_devices_get - Get device details
• ninjaone_devices_reboot - Schedule a device reboot
• ninjaone_devices_services - List Windows services on a device
• ninjaone_devices_alerts - Get device-specific alerts
• ninjaone_devices_activities - View device activity log
• ninjaone_devices_get_custom_fields - Get device custom fields
• ninjaone_devices_update_custom_fields - Update device custom fields

Organizations

Manage customer organizations and their resources.

Tools:

• ninjaone_organizations_list - List organizations
• ninjaone_organizations_get - Get organization details
• ninjaone_organizations_create - Create a new organization
• ninjaone_organizations_locations - List organization locations
• ninjaone_organizations_devices - List devices for an organization
• ninjaone_organizations_get_custom_fields - Get organization custom fields
• ninjaone_organizations_update_custom_fields - Update organization custom fields

Alerts

View and manage alerts across all devices.

Tools:

• ninjaone_alerts_list - List alerts with filters
• ninjaone_alerts_get - Get a single alert by UID (renders as an interactive card in MCP Apps hosts)
• ninjaone_alerts_reset - Reset/dismiss a single alert
• ninjaone_alerts_reset_all - Reset all alerts for a device or organization
• ninjaone_alerts_summary - Get alert count summary

Features:

• Interactive Alert Card (MCP Apps, SEP-1865): ninjaone_alerts_get renders as an interactive card in MCP Apps hosts (Claude Desktop/web) with an in-card "Reset alert" round-trip via ninjaone_alerts_reset; neutral by default, brandable via window.__BRAND__ injection or MCP_BRAND_* env vars; plain-JSON behavior is unchanged in other hosts

Tickets

Manage service tickets.

Tools:

• ninjaone_tickets_list - List tickets from a board (requires board_id; status/organization_id/device_id filters are applied client-side, see notes below)
• ninjaone_tickets_get - Get ticket details
• ninjaone_tickets_create - Create a new ticket
• ninjaone_tickets_update - Update an existing ticket
• ninjaone_tickets_add_comment - Add a comment to a ticket
• ninjaone_tickets_comments - Get ticket comments
• ninjaone_tickets_boards_list - List ticket boards (to discover board_id values)

Note: NinjaOne queries tickets per board, and board IDs vary by tenant — board 1 is not always the "All Tickets" board, so ninjaone_tickets_list requires an explicit board_id rather than silently guessing one. Discover IDs with ninjaone_tickets_boards_list; on tenants where that endpoint returns 404, read the numeric ID from the board link's URL in the NinjaOne web UI (e.g. the "All tickets" sidebar link).

Note: NinjaOne's board-run API cannot filter tickets by status, organization, or device server-side (attempting to throws a generic Bad request). ninjaone_tickets_list therefore applies those filters client-side within one board page. The response separates count (matches in this page) from scanned (tickets examined) and includes hasMore/cursor — page through until hasMore is false to get every match, and never treat a single page's count as a board-wide total. Status is matched against each ticket's status display name, so custom board statuses may not map to the OPEN/IN_PROGRESS/WAITING/CLOSED values.

Similarly, ninjaone_devices_list filters by organization_id through NinjaOne's dedicated per-organization endpoint (the general df=org device filter is unreliable and can silently return the full fleet).

Navigation Tools

Always available:

• ninjaone_navigate - Select a domain to work with
• ninjaone_status - Show current state and credential status
• ninjaone_back - Return to main menu (when in a domain)

Example Workflow

User: Check my devices
Claude: [calls ninjaone_navigate with domain="devices"]
       -> Navigated to devices domain. Available tools: ...

User: List all Windows servers
Claude: [calls ninjaone_devices_list with device_class="WINDOWS_SERVER"]
       -> [device list results]

User: Now show me alerts
Claude: [calls ninjaone_back]
       -> Navigated back to main menu.
       [calls ninjaone_navigate with domain="alerts"]
       -> Navigated to alerts domain.
