MCP Server

MCP Server

Developed By MX Modules

Compatible with WHMCS v8.13

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.

Easy to set up and get working with Claude. Useful as part of a flow to query WHMCS to get customer details and tailor messages. Looking forward to finding ways to build on this as part of our customer support and website care automations.
