What is MCP Server for WHMCS?

MCP Server is a WHMCS addon that implements the Model Context Protocol (MCP), an open standard by Anthropic. It exposes 45 tools across 9 categories: client management, products and services, orders, invoices, quotes, support tickets, proposals, business metrics, and system operations. Instead of clicking through WHMCS admin screens, you ask questions in plain English through Claude, ChatGPT, Cursor, or any of 80+ MCP-compatible clients. The addon installs in your WHMCS modules folder, requires PHP 8.0+ and WHMCS 8.0+, and uses Bearer token authentication on every request. Every API call is logged with timestamp, action, and result. Your data stays on your server. For privacy-conscious setups, you can use local LLMs like Ollama where no data leaves your infrastructure. Pricing starts at $22/month with a 15-day free trial.

Frequently Asked Questions

Do you offer a free trial?
Yes. You get a full 15-day free trial with complete access to all 46 MCP tools. Enter your payment details to start, and you will not be charged until day 16. Cancel anytime during the trial at no cost
I'm a solo operator with 20 clients. Do I need this?
Probably not yet. MCP Server shines when you have a team asking frequent questions about clients, invoices, and services, or when you're managing 50+ clients and switching between WHMCS tabs wastes hours weekly. If you're small and solo, you might not see enough ROI yet.
Do you offer a lifetime license?
No. MCP Server is subscription-only at $22/month or $240/year. However, you can try it free for 15 days before committing. We actively develop new MCP tools, maintain compatibility with WHMCS updates, and provide ongoing support.
What is the Model Context Protocol (MCP)?
MCP is an open protocol developed by Anthropic that allows AI assistants to securely access external data sources and tools. It provides a standardized way for AI models to interact with your business systems. Learn more at modelcontextprotocol.io.
Which AI assistants are supported?
MCP Server works with any MCP-compatible client: Claude, ChatGPT, Cursor, VS Code, n8n, and 80+ other tools. For privacy-conscious users, local LLMs like Ollama and LM Studio keep all prompts and responses on your infrastructure. See the full list at /modules/mcp-server/compatible-tools.
Is my WHMCS data secure?
Yes. Every request requires a valid Bearer token. You control which tools are available through global tool management settings. Every action is logged for audit purposes.
Can I use this without sending data to OpenAI or Anthropic?
Yes. MCP Server uses the standard Model Context Protocol, which works with local LLMs like Ollama or LM Studio. With a local setup, your prompts and WHMCS data never leave your infrastructure. Ideal for privacy-conscious businesses or regulated industries.
Do I need coding knowledge to install this?
No. Installation is straightforward: upload the module files to your WHMCS, configure your API credentials in the admin panel, and you are ready to connect your AI assistant. See our installation guide at /docs/mcp-server for step-by-step instructions.
What WHMCS versions are supported?
MCP Server supports WHMCS 8.0 and newer. We recommend using the latest stable version of WHMCS for optimal compatibility and security.

Stop clicking through WHMCS menus

Ask Claude about your clients instead. We built this because we got tired of searching for client info manually.
