Instructions

Implementation Reference

• src/core/tools/vps.ts:689-721 (schema)

  Schema/definition of the VPS_updatePostInstallScriptV1 tool: a PUT request to /api/vps/v1/post-install-scripts/{postInstallScriptId} with input properties for postInstallScriptId (integer), name (string), and content (string), all required.

  {
    "name": "VPS_updatePostInstallScriptV1",
    "description": "Update a specific post-install script.\n\nUse this endpoint to modify existing automation scripts.",
    "method": "PUT",
    "path": "/api/vps/v1/post-install-scripts/{postInstallScriptId}",
    "inputSchema": {
      "type": "object",
      "properties": {
        "postInstallScriptId": {
          "type": "integer",
          "description": "Post-install script ID"
        },
        "name": {
          "type": "string",
          "description": "Name of the script"
        },

• src/servers/vps.ts:3-6 (registration)

  Registration entry point: imports the tools array from src/core/tools/vps.ts and passes it to startServer, which registers all tools including VPS_updatePostInstallScriptV1 with the MCP server.

  import { startServer } from '../core/runtime.js';
  import tools from '../core/tools/vps.js';
  
  startServer({ name: 'hostinger-vps-mcp', version: '0.1.42', tools });

• src/core/runtime.ts:1909-1999 (handler)

  Handler/execution logic for the tool. Since VPS_updatePostInstallScriptV1 is an API-based tool (not custom), the executeApiCall method in MCPServer (runtime.ts) handles it: it takes the tool's method (PUT) and path, substitutes path parameters (postInstallScriptId), sends the remaining params (name, content) as JSON body in a PUT request via axios.

  private async executeApiCall(tool: OpenApiTool, params: Record<string, any>): Promise<any> {
    // 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: AxiosRequestConfig = {
        method: method.toLowerCase(),
        url,
        headers: { ...this.headers },
        timeout: 60000, // 60s
        validateStatus: function (status: number): boolean {
          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) {
        config.headers['Authorization'] = `Bearer ${bearerToken}`;
      } else {
        this.log('error', `Bearer Token environment variable not found: API_TOKEN`);
      }
  
      // Add parameters based on request method
      if (["GET", "DELETE"].includes(method)) {
        // For GET/DELETE, send params as query string
        config.params = { ...(config.params || {}), ...requestParams };
      } else {
        // For POST/PUT/PATCH, send params as JSON body
        config.data = requestParams;
        if (config.headers) {
          config.headers["Content-Type"] = "application/json";
        }
      }
  
      this.log('debug', "Request config:", {
        url: config.url,
        method: config.method,
        params: config.params,
        headers: config.headers ? Object.keys(config.headers) : []
      });
  
      // Execute the request
      const response = await axios(config);
      this.log('debug', `Response status: ${response.status}`);
  
      return response.data;
  
    } catch (error) {
      const errorMessage = error instanceof Error ? error.message : String(error);
      this.log('error', `API request failed: ${errorMessage}`);
  
      if (axios.isAxiosError(error)) {
        const axiosError = error as AxiosError;
        const responseData = axiosError.response?.data;
        const responseStatus = axiosError.response?.status;
  
        this.log('error', 'API Error Details:', {
          status: responseStatus,
          data: typeof responseData === 'object' ? JSON.stringify(responseData) : String(responseData)
        });
  
        // Rethrow with more context for better error handling
        const detailedError = new Error(`API request failed with status ${responseStatus}: ${errorMessage}`);
        (detailedError as any).response = axiosError.response;
        throw detailedError;
      }
  
      throw error;
