MCP server for WHMCS. It lets Claude (or any MCP client) manage clients, services, orders, invoices, quotes, domains, tickets and system settings through the WHMCS External API.
128 typed tools for the common workflows, with validated parameters and WHMCS quirks handled for you:
PHP bracket notation, base64(serialize()) for custom fields, parallel arrays for AddOrder, numbered
invoice lines, and booleans sent as 1/0.
whmcs_call_api runs any of the 162 WHMCS actions, and custom actions added by addon modules.
whmcs_list_actions lists them with their kind and documentation link.
Safety: read-only mode, confirm: true required on destructive tools, sensitive actions turned off by
default, and MCP annotations (readOnlyHint / destructiveHint) on every tool.
Responses are compact JSON. WHMCS list wrappers ({"clients":{"client":[…]}}) are collapsed into arrays, and
very large payloads are truncated with a hint to paginate.
Create them in WHMCS under Configuration → System Settings → Manage API Credentials. Assign an API role that grants only the actions you need.
claude mcp add whmcs \
-e WHMCS_API_URL=https://your-whmcs.com/includes/api.php \
-e WHMCS_IDENTIFIER=your_identifier \
-e WHMCS_SECRET=your_secret \
-- npx -y mcp-whmcsThe password is MD5-hashed before it is sent, which is what WHMCS expects.
claude mcp add whmcs \
-e WHMCS_API_URL=https://your-whmcs.com/includes/api.php \
-e WHMCS_USERNAME=your_admin_user \
-e WHMCS_PASSWORD=your_admin_password \
-- npx -y mcp-whmcsbunx mcp-whmcs works in place of npx -y mcp-whmcs. For a read-only assistant, add
-e WHMCS_READ_ONLY=true.
By default WHMCS accepts API calls only from allowed IPs. You can do either of the following:
Add the IP of the machine that runs the server under Configuration → System Settings → General Settings → Security → API IP Access Restriction.
Or set $api_access_key = '...'; in WHMCS configuration.php and pass the same value as WHMCS_ACCESS_KEY.

Requires Bun.
bun installbun run checkbun run buildcheck runs oxfmt, oxlint (including the vendored
anti-slop plugin in tools/oxlint/anti-slop) and tsc.
bun test runs the live tests in test/live.test.ts against the WHMCS instance configured in .env. The test
server always runs with WHMCS_READ_ONLY=true, so it can't create, change or delete records.
bun run inspect opens the server in the MCP Inspector.
