Implementation Reference

  • Core implementation of the whmcs_add_client tool: calls WHMCS 'AddClient' API action via the generic call() method, handling parameters and response.
    async addClient(params: { firstname: string; lastname: string; email: string; address1: string; city: string; state: string; postcode: string; country: string; phonenumber: string; password2: string; companyname?: string; address2?: string; currency?: number; clientip?: string; language?: string; groupid?: number; securityqid?: number; securityqans?: string; notes?: string; cardtype?: string; cardnum?: string; expdate?: string; startdate?: string; issuenumber?: string; cvv?: string; noemail?: boolean; skipvalidation?: boolean; }) { return this.call<WhmcsApiResponse & { clientid: number; owner_user_id: number; }>('AddClient', params); }
  • src/index.ts:91-121 (registration)
    MCP tool registration for 'whmcs_add_client', including schema definition and thin handler delegating to WhmcsApiClient.addClient()
    'whmcs_add_client', { title: 'Add Client', description: 'Create a new client in WHMCS', inputSchema: { firstname: z.string().describe('Client first name'), lastname: z.string().describe('Client last name'), email: z.string().email().describe('Client email address'), address1: z.string().describe('Street address'), city: z.string().describe('City'), state: z.string().describe('State/Province'), postcode: z.string().describe('Postal/ZIP code'), country: z.string().describe('Country (2-letter ISO code)'), phonenumber: z.string().describe('Phone number'), password2: z.string().describe('Password for the client account'), companyname: z.string().optional().describe('Company name'), address2: z.string().optional().describe('Address line 2'), currency: z.number().optional().describe('Currency ID'), language: z.string().optional().describe('Client language'), groupid: z.number().optional().describe('Client group ID'), notes: z.string().optional().describe('Admin notes'), noemail: z.boolean().optional().describe('Do not send welcome email'), }, }, async (params) => { const result = await whmcsClient.addClient(params); return { content: [{ type: 'text', text: JSON.stringify(result, null, 2) }], }; } );
  • Generic low-level API caller used by all tools including addClient: handles authentication, param flattening, HTTP POST to /includes/api.php, error handling, and JSON response parsing.
    async call<T extends WhmcsApiResponse>(action: string, params: Record<string, unknown> = {}): Promise<T> { const url = `${this.config.apiUrl.replace(/\/$/, '')}/includes/api.php`; const postData: Record<string, string> = { identifier: this.config.apiIdentifier, secret: this.config.apiSecret, action: action, responsetype: 'json', ...this.flattenParams(params) }; if (this.config.accessKey) { postData.accesskey = this.config.accessKey; } const response = await fetch(url, { method: 'POST', headers: { 'Content-Type': 'application/x-www-form-urlencoded', }, body: new URLSearchParams(postData).toString(), }); if (!response.ok) { throw new Error(`WHMCS API request failed: ${response.status} ${response.statusText}`); } const data = await response.json() as T; if (data.result === 'error') { throw new Error(`WHMCS API error: ${data.message || 'Unknown error'}`); } return data; }
