How to Set Up and Use WHMCS
The WHMCS MCP Server connects AI assistants to a WHMCS billing and hosting automation installation, exposing comprehensive management capabilities across eight domains: client accounts, products and invoices, support tickets, domain registrations, orders, server provisioning, system administration, and affiliate programs. Credentials are supplied via environment variables and the server is available as a Docker image for zero-configuration deployment, making it straightforward to give Claude secure, API-level access to your hosting business operations without building custom integrations.
Prerequisites
- A running WHMCS installation accessible over HTTPS
- WHMCS API credentials: an API Identifier and API Secret generated in WHMCS Admin > Setup > API Credentials
- Docker (for the recommended containerized deployment) or Node.js 18+ for source builds
- IP whitelisting configured in WHMCS for the machine running the MCP server
Generate WHMCS API credentials
Log into your WHMCS admin panel and go to Setup > API Credentials. Create a new API role with the permissions you need and generate an Identifier/Secret pair. Note the API Access Key if you want an additional security layer.
Run with Docker (recommended)
Pull the pre-built image and run it with your WHMCS credentials passed as environment variables. Docker is the fastest path to a working deployment.
docker run -it --rm \
-e WHMCS_API_URL="https://billing.example.com/" \
-e WHMCS_API_IDENTIFIER="your-identifier" \
-e WHMCS_API_SECRET="your-secret" \
ghcr.io/scarecr0w12/whmcs-mcp-tool:latestOr build from source
Clone the repository, install dependencies, copy the environment template, and build the TypeScript source.
git clone https://github.com/scarecr0w12/whmcs-mcp-tool.git
cd whmcs-mcp-tool
npm install
cp .env.example .env
# Edit .env with your credentials
npm run buildVerify the WHMCS connection
Before connecting to Claude, run the built-in test script to confirm the server can reach your WHMCS API and authenticate successfully.
npx tsx src/test.tsConfigure Claude Desktop
Add the server to claude_desktop_config.json with your credentials as environment variables. Never commit these values to version control.

}Prompts to try
These prompts demonstrate how Claude can manage a WHMCS hosting operation through the MCP server.
- "List all open support tickets and summarize the most urgent ones."
- "Look up the account for customer [email protected] and show their active services and outstanding invoices."
- "Register the domain example-new.com for client ID 1234 using the default registrar."Troubleshooting WHMCS
API returns 'Invalid IP' error
WHMCS by default restricts API access to whitelisted IP addresses. Go to WHMCS Admin > Setup > General Settings > Security and add the IP address of the machine running the MCP server to the API IP Whitelist.
Authentication fails with correct credentials
Confirm WHMCS_API_URL ends with a trailing slash (e.g., 'https://billing.example.com/'). Some WHMCS installations also require the ACCESS_KEY variable. Run 'npx tsx src/test.ts' for a detailed error message.
npm run build fails with TypeScript errors
Ensure you are using Node.js 18 or later ('node --version'). Run 'npm install' again to ensure all dependencies including TypeScript itself are present, then retry the build.
