Frequently Asked Questions
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. Cancel anytime. 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.
What are MCP Prompts (slash commands)?
MCP Prompts are pre-built workflow templates that appear as slash commands in your AI client. Type /onboard_client, /chase_overdue_invoices, or /audit_expiring_domains and the AI runs the full chain of tools automatically. We ship 10 prompts: 7 core (onboarding, ticket replies, account reviews, fraud investigation, product setup, overdue invoices, expiring domains), 2 with MX Metrics (revenue analysis, business snapshot), and 1 with MX Proposals (draft proposal). See the full reference at /docs/mcp-server/prompts.
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.
