MCP Server for managing WHMCS installations - clients, products, billing, tickets, domains, and integrations
If you already use Whmcs MCP Tool, the whmcs mcp tool mcp server is the piece that lets your assistant work with it directly. MCP Server for managing WHMCS installations - clients, products, billing, tickets, domains, and integrations.
A Model Context Protocol (MCP) server for managing WHMCS (Web Host Manager Complete Solution) installations. This server provides comprehensive tools for managing clients, products, billing, support tickets, domains, and more through the WHMCS API.
The toolset is worth reading before you wire it up, because it tells you what the integration is really for:
whmcs_get_clients — Get list of clientswhmcs_get_client_details — Get detailed client informationwhmcs_add_client — Create a new clientwhmcs_update_client — Update an existing clientwhmcs_delete_client — Delete a clientwhmcs_get_client_products — Get client's products/serviceswhmcs_get_client_domains — Get client's domainswhmcs_get_products — Get available productswhmcs_get_product_groups — Get product groupswhmcs_get_invoices — Get invoiceswhmcs_get_invoice — Get invoice detailswhmcs_create_invoice — Create an invoiceInstallation goes through your MCP client rather than a global install: point it at tsx on npm and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.
Configuration is passed through the environment: WHMCS_API_URL, WHMCS_API_SECRET, WHMCS_ACCESS_KEY. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
Among the payments and commerce options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Whmcs MCP Tool's toolset — whmcs_get_clients, whmcs_get_client_details, whmcs_add_client and 11 more — is a fair guide to whether it matches your workflow. It is maintained by scarecr0w12; worth a glance at recent repository activity before you build anything load-bearing on it.
