CIPP MCP Server

MCP (Model Context Protocol) server for CIPP — the CyberDrain Improved Partner Portal. Provides AI assistants with structured access to CIPP's M365 multi-tenant management capabilities.

Features

• 45 tools across 12 categories
• Tenant, user, group, and mailbox management
• Mailbox and online-archive size reporting, per tenant or per user
• Security: Conditional Access policies, named locations
• Standards & compliance: BPA, domain health, drift detection
• License reporting (per-tenant and CSP-wide)
• Alerts, audit logs, and scheduled tasks
• GDAP role and invite management
• Stdio and HTTP transport modes
• MCP Gateway compatible

Prerequisites

• Node.js 18+
• A running CIPP deployment
• CIPP API Key (generated from CIPP Settings → API Client Management)

Installation

Via npm (once published)

npx cipp-mcp

From source

git clone https://github.com/WYRE-AI/cipp-mcp
cd cipp-mcp
npm install
npm run build

Configuration

Set these environment variables (or copy .env.example to .env):

Usage with Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "cipp": {
      "command": "node",
      "args": ["/path/to/cipp-mcp/dist/entry.js"],
      "env": {
        "CIPP_BASE_URL": "https://cippXXXXX.azurewebsites.net",
        "CIPP_TENANT_ID": "your-entra-tenant-id",
        "CIPP_CLIENT_ID": "your-client-id",
        "CIPP_CLIENT_SECRET": "your-client-secret"
      }
    }
  }
}

Note: CIPP_BASE_URL must be the Azure Function App URL (.azurewebsites.net), not the frontend SWA URL (.azurestaticapps.net or your custom domain). The SWA enforces browser-based auth and will redirect all API requests to a Microsoft login page.

Tools

Mailbox and archive sizes

list_mailbox_usage reports every mailbox in a tenant — primary size, item count, quota, percent of quota, and the same four figures for the online archive — sorted largest first, with tenant-wide totals that cover every mailbox even when only the top rows are returned.

It requires CIPP's reporting database to have been synced for that tenant. This is not a design choice: Invoke-ListMailboxes' live Exchange query selects no size fields at all, so the cache is the only tenant-wide source of sizes. Sync it from CIPP under Reports → Report Settings. If it has not been synced the tool says so and names the remedy rather than returning an empty result.

get_mailbox_usage reports the same figures for a single mailbox and reads live, so it needs no cache. Prefer it when the cache is unavailable or stale.

Two caveats worth knowing:

• Concealed report names blank the tenant-wide sizes. With Reports: conceal user, group, and site names enabled in the Microsoft 365 admin centre, Graph's usage report returns 32-character hashes instead of UPNs, so CIPP's join against the mailbox list matches nothing and every mailbox caches a size of 0 — a tenant that reads as empty rather than as failed. list_mailbox_usage detects this and returns a warning alongside the totals. get_mailbox_usage is unaffected: it reads the Exchange admin API directly.
• Sizes are gigabyte-rounded on the per-user path. CIPP rounds to two decimal places of a gigabyte before returning, so get_mailbox_usage byte counts are accurate to roughly 10 MB. Quotas are exact — they are recovered from the raw Get-Mailbox string, which carries the true byte count.

CIPP version compatibility

Request bodies are shaped against CIPP's own Invoke-*.ps1 handlers and are written to satisfy both current and older CIPP builds — where the two differ, the server sends the form both accept. Three behaviours are worth knowing:

• offboard_user reports queued, not completed. CIPP's ExecOffboardUser returns HTTP 200 the instant the job is created; it never waits for or reports the offboarding result. Confirm the outcome in CIPP's Offboarding view before treating an account as offboarded. The tool refuses a call with no actions selected, since that would otherwise queue a job that succeeds while doing nothing.
• Some endpoints report failure under HTTP 200. EditUser, AddScheduledItem and ExecOffboardUser return error text in Results rather than an error status. These tools parse Results and return status: "failed"; do not treat a 200 as success.
• Two parameters need a recent CIPP. offboard_user's DisableOneDriveSharing and set_out_of_office's timezone are ignored by older builds rather than erroring — so an offboarding that selects only DisableOneDriveSharing will run no actions on an older CIPP.

Authentication Setup

CIPP's API Client Management page provisions an Entra ID app registration and returns an OAuth client ID + client secret (not a long-lived Bearer token). The server exchanges these for a short-lived access token on each request using the OAuth 2.0 client-credentials flow, and caches the token until just before its expiry.

1. In CIPP, go to Settings → CIPP Settings → Integrations → CIPP-API
2. Create a new API client
3. Copy the Client ID and Client Secret — you will not be able to retrieve the secret later
4. Configure the server with the Function App URL (see below):
   env

   CIPP_BASE_URL=https://cippXXXXX.azurewebsites.net
   CIPP_TENANT_ID=<your-entra-tenant-id>
   CIPP_CLIENT_ID=<client-id-from-cipp>
   CIPP_CLIENT_SECRET=<client-secret-from-cipp>
   

If you already have a static Bearer token (older CIPP deployments), set CIPP_API_KEY instead and leave the OAuth variables unset. When both are provided, CIPP_API_KEY wins.

Finding your Function App URL

CIPP runs as an Azure Static Web App (SWA) backed by an Azure Function App. The SWA URL (your custom domain or *.azurestaticapps.net) enforces browser-only auth and cannot be used as CIPP_BASE_URL. Use the Function App URL instead.

Self-hosted CIPP: Find the Function App in the Azure portal (look for an App Service with Kind: functionapp in the same resource group as your SWA), or run:

az staticwebapp show --name <your-swa-name> --resource-group <rg> \
  --query "linkedBackends[0].backendResourceId" -o tsv

CIPP-sponsored hosting: Contact the CIPP team for your instance's Function App URL — it is not the same as the URL shown in your browser.

IP Allowlist

CIPP validates each API client against an IPRange field stored in Azure Table Storage. If your server's public IP is not in this list, you will receive:

Access to this CIPP API endpoint is not allowed, the API Client does not have the required permission

Self-hosted: Add your IP via the CIPP UI (Settings → API Client Management) or directly in the ApiClients table of your CIPP storage account.

CIPP-sponsored hosting: Ask the CIPP team to add your server's public IP to your API client's allowed range.
