MCP Server

Connect AI to Your WHMCS

MCP Server brings AI assistants directly into your WHMCS workflow. Ask questions in plain English and get instant answers from your client data, invoices, tickets, and more. No external APIs. Your data stays on your server.

What is MCP?

The Model Context Protocol (MCP) is an open standard developed by Anthropic that lets AI assistants securely access external data. MCP Server implements this protocol for WHMCS, making your business data available to Claude, ChatGPT, or any MCP-compatible client.

What Can You Do?

Ask questions like:

"Show me my top 10 clients by revenue"
"Which invoices are overdue?"
"Tell me everything about client #42"
"Create an invoice for consulting services"
"Summarize open support tickets"

The AI reads your WHMCS data and responds with real information.

28 Tools Included
