Run your entire WHMCS with plain English
A self-hosted WHMCS addon that connects Claude, ChatGPT, Cursor and every MCP client straight to your install — managing clients, invoices, tickets, domains and hosting in plain English.
Why choose WHMCS MCP Server
Purpose-built for hosting providers who want AI hosting automation without handing their billing data to a third party.
Natural language, not dashboards
Ask “which clients are overdue and what do they owe?” and get an answer pulled live from WHMCS — no reports to build, no SQL.
One endpoint, every AI client
Built on Anthropic’s Model Context Protocol, so any MCP-compatible assistant works the day it ships. No per-tool integrations.
Self-hosted, licence-friendly
Runs as a normal WHMCS addon module on your own server. Nothing is proxied, nothing is stored outside your install.
Scoped, audited, reversible
Per-token tool permissions, rate limiting and a complete audit log mean AI access is as tight as any staff role.

Read the security model →What is a WHMCS MCP server, and why use one?
The WHMCS MCP Server is a native WHMCS server module that turns your billing system into something an AI assistant can actually talk to. It implements the Model Context Protocol, so Claude, ChatGPT, Cursor and Windsurf connect straight to your install and work with real clients, invoices, services and domains — no exports, no copy-paste, no third-party middleware.
If you have been searching for a WHMCS AI connector or a WHMCS MCP connector, this is that — but self-hosted. It installs as a standard addon module inside your own WHMCS, so your billing data never leaves your server. There is a free WHMCS MCP server module to start with: it exposes 20 read-only tools, and the Pro licence unlocks the 39 write tools that create orders, raise invoices, provision services and manage domains.
Free WHMCS MCP server module
A no-cost, read-only build. Ask about any client, invoice, domain, service or ticket. Nothing can be changed, so it is safe to connect on day one.
WHMCS server module
Installed the normal way, under modules/addons/. No core edits, no cron, and it works with a renamed admin directory.
WHMCS AI connector
Bring your own model. The module is the server side — your AI client supplies the intelligence, so there is no OpenAI or Anthropic key to buy here.
WHMCS MCP connector
One URL and an API key. Paste it into Claude Desktop as a custom connector, or into Cursor, Windsurf, Cline and VS Code with an Authorization header.
WHMCS MCP server module — common questions
Is there a free WHMCS MCP server module?
Yes. The free WHMCS MCP server module is a complete, read-only build with 20 tools. It reads clients, contacts, invoices, transactions, credit, domains, services, products and tickets, and it physically cannot write — the licence client is not in the package, so the write tools stay switched off. Download it, connect an AI client, and upgrade later only if you want the AI to act rather than answer.
What is the difference between a WHMCS AI connector and a WHMCS MCP connector?
In practice they describe the same thing from two directions. A WHMCS AI connector is the outcome — your billing system reachable by an AI assistant. A WHMCS MCP connector is the mechanism: the Model Context Protocol, the open standard those assistants use to discover and call tools. This module is an MCP server, which is what makes it work in Claude, ChatGPT, Cursor and Windsurf without a separate integration for each.
How do I install the WHMCS server module?
Upload the mcpserver folder to modules/addons/, activate it under System Settings → Addon Modules, then create an API key. The module hands you the connector URL ready to paste. It is a standard WHMCS server module — no core file edits and no cron job required.
What can the WHMCS MCP server actually do?
59 tools in total. The free build answers questions — who is this client, what is unpaid, which domains expire this month, what is open in support. The Pro licence adds the write side: create and accept orders, create products, raise and send invoices, record payments, apply credit and refunds, adjust pricing, provision, suspend, upgrade and terminate services, register, renew and transfer domains, and work tickets end to end.
Is a self-hosted WHMCS MCP server safe to run?
It is the safer option, because nothing leaves your infrastructure. The module runs inside your own WHMCS and talks to it internally — there is no cloud relay and no copy of your billing database anywhere else. Access is gated at five independent levels, every call is written to an audit log, and the package ships read-only until an administrator deliberately enables writes.
