• src/core/tools/billing.ts:149-172 (schema)

    "description": "Enable auto-renewal for a subscription.\n\nUse this endpoint when enable auto-renewal for a subscription.",
    "method": "PATCH",

• src/servers/billing.js:1-6 (registration)

  Server entry point that registers all billing tools (including billing_enableAutoRenewalV1) by importing the tools array and passing to startServer.

  #!/usr/bin/env node
  // Auto-generated entry for group: billing
  import { startServer } from '../core/runtime.js';
  import tools from '../core/tools/billing.js';
  
  startServer({ name: 'hostinger-billing-mcp', version: '0.1.40', tools });

• src/core/runtime.js:1879-1999 (handler)

  Generic API call handler (executeApiCall) that handles billing_enableAutoRenewalV1. Since this tool is not marked as 'custom', it's executed as a standard API call: it extracts subscriptionId from params, substitutes it into the path PATCH /api/billing/v1/subscriptions/{subscriptionId}/auto-renewal/enable, and sends the HTTP request.

  async executeApiCall(tool, params) {
    // Get method and path from tool
    const method = tool.method;
    let path = tool.path;
  
    // Clone params to avoid modifying the original
    const requestParams = { ...params };
  
    // Replace path parameters with values from params
    Object.entries(requestParams).forEach(([key, value]) => {
      const placeholder = `{${key}}`;
      if (path.includes(placeholder)) {
        path = path.replace(placeholder, encodeURIComponent(String(value)));
        delete requestParams[key]; // Remove used parameter
      }
    });
  
    // Build the full URL
    const baseUrl = this.baseUrl.endsWith("/") ? this.baseUrl : `${this.baseUrl}/`;
    const cleanPath = path.startsWith("/") ? path.slice(1) : path;
    const url = new URL(cleanPath, baseUrl).toString();
  
    this.log('debug', `API Request: ${method} ${url}`);
  
    try {
      // Configure the request
      const config = {
        method: method.toLowerCase(),
        url,
        headers: { ...this.headers },
        timeout: 60000, // 60s
        validateStatus: function (status) {
          return status < 500; // Resolve only if the status code is less than 500
        }
      };
    
      const bearerToken = process.env['API_TOKEN'] || process.env['APITOKEN']; // APITOKEN for backwards compatibility
      if (bearerToken) {
        config.headers['Authorization'] = `Bearer ${bearerToken}`;

        config.params = { ...(config.params || {}), ...requestParams };
      } else {

      });
  
      // Execute the request
      const response = await axios(config);
      this.log('debug', `Response status: ${response.status}`);
