Common questions

Is WHMCS MCP Server safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: MCP_TRANSPORT, WHMCS_API_URL, WHMCS_IDENTIFIER, WHMCS_SECRET, LICENSE_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (2.3.8) reached the registry 12 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Docker on your computer.

What can I use instead?

WHMCS MCP Server

Production-grade AI integration for WHMCS. Connect ChatGPT, Claude, and Cursor directly to your WHMCS installation — manage clients, invoices, tickets, and services through natural language.

You: "Send a payment reminder to all clients with overdue invoices over $50"

AI: Fetching overdue invoices... Found 12. Sending reminder emails... Done.

Prerequisites — WHMCS API Setup

Before running the installer you need a WHMCS API credential with the right permissions.

1. Create an API Role

In WHMCS Admin: Setup → Staff Management → API Roles → Add Role

Choose a permission preset based on how much you trust the AI:

Minimum permissions (read-only — AI can look but not touch): GetClients GetClientsDetails GetClientsProducts GetClientsDomains GetClientsAddons GetClientGroups GetContacts GetEmails GetInvoice GetInvoices GetOrders GetOrderStatuses GetProducts GetTicket GetTickets GetSupportDepartments GetQuotes GetCredits GetTransactions GetStats GetActivityLog GetCancelledPackages GetEmailTemplates GetCurrencies GetPaymentMethods GetHealthStatus GetProductGroups GetRegistrars GetServers GetAffiliates GetAnnouncements GetSupportStatuses GetTicketCounts GetTicketPredefinedCats GetAdminUsers GetToDoItems GetToDoItemStatuses GetStaffOnline DomainWhois DomainGetNameservers DomainGetLockingStatus GetTLDPricing GetPromotions GetProjects GetProject

Maximum permissions (full access — AI can take any action): Everything above, plus: AddClient UpdateClient AddClientNote AddContact UpdateContact CreateInvoice AddInvoicePayment AddOrder AcceptOrder CancelOrder OpenTicket AddTicketReply UpdateTicket CreateQuote UpdateQuote SendQuote AcceptQuote DeleteQuote AddCredit ApplyCredit AddBillableItem SendEmail UpdateClientProduct ModuleSuspend ModuleUnsuspend ModuleTerminate ModuleCreate UpgradeProduct DomainRegister DomainTransfer DomainRenew DomainUpdateNameservers DomainUpdateLockingStatus DomainToggleIdProtect FraudOrder PendingOrder UpdateInvoice ModuleChangePw LogActivity AddTicketNote AffiliateActivate CreateProject UpdateProject AddProjectTask UpdateProjectTask DeleteProjectTask AddProjectMessage StartTaskTimer EndTaskTimer

Project Management tools: list_projects through end_task_timer additionally require the WHMCS Project Management addon to be active (Setup → Addon Modules), regardless of API role permissions.

Domain write permissions: register_domain, transfer_domain, and renew_domain require

DomainRegister, DomainTransfer, and DomainRenew respectively. Note the Domain prefix

comes first — RegisterDomain / TransferDomain / RenewDomain are not valid WHMCS permission

keys and are silently ignored if granted. If a domain tool returns HTTP 403, the matching

permission is missing from your role. Upgrading from 2.3.1 or earlier? See the

2.3.2 changelog entry — you need to re-grant these three under their correct

names.

Tip: Start with minimum permissions and add write permissions only as needed. This limits blast radius if an AI client goes rogue or gets a bad prompt.

2. Set an API Access Key (recommended)

An Access Key bypasses IP restrictions entirely — the recommended approach since the MCP server's outbound IP can change (Docker restarts, server moves, etc.).

Add this line to your configuration.php in the WHMCS root:

$api_access_key = 'your-secret-passphrase';

Allowed characters: letters, numbers, and ! @ # $ % . ( ) * [ ] - _

Then set WHMCS_ACCESS_KEY to the same value in your .env or Portainer stack.

3. Create an API Credential

Setup → Staff Management → API Credentials → Generate New Credential

Role: select the role you just created
Allowed IPs: leave blank if using an Access Key (recommended), or enter the server IP if you prefer IP-based restrictions
Copy the Identifier and Secret — you'll need these during install

Quick Start — running in under 5 minutes

Binary (no Docker required):

curl -fsSL https://daddar.io/whmcs-mcp/install.sh | sudo bash

Prompts for your WHMCS credentials and license key, installs the binary to /usr/local/bin, and registers a systemd service.

Docker (recommended for servers already running Docker):

curl -fsSL https://daddar.io/whmcs-mcp/install-docker.sh | bash

Prompts for credentials, writes .env, and starts the stack via Docker Compose.

Get a License

Purchase a license at [daddar.io/store/ai-tools/whmcs-mcp](https://daddar.io/store/ai-tools/whmcs-mcp) — after checkout, your license key appears in the client portal. Paste it into setup.sh when prompted.

No license? A 14-day free trial starts automatically on first run.
