Implementation Reference

• src/core/tools/dns.ts:95-118 (schema)

  Schema/registration definition for DNS_getDNSRecordsV1 tool. Defines the tool name, description, HTTP method (GET), path (/api/dns/v1/zones/{domain}), input schema (requires 'domain' parameter), and security configuration. This is a standard API tool (not custom) that gets routed through executeApiCall.

• src/core/tools/dns.ts:95-118 (registration)

  Registration: The tool is registered as part of the dns tool list export in src/core/tools/dns.ts. It is imported by src/servers/dns.ts and passed to startServer(), which initializes the MCPServer with all tools in the list. The tool is not 'custom', so it flows through executeApiCall in runtime.js.

  {
    "name": "DNS_getDNSRecordsV1",
    "description": "Retrieve DNS zone records for a specific domain.\n\nUse this endpoint to view current DNS configuration for domain management.",
    "method": "GET",
    "path": "/api/dns/v1/zones/{domain}",
    "inputSchema": {
      "type": "object",
      "properties": {
        "domain": {
          "type": "string",
          "description": "Domain name"
        }
      },
      "required": [
        "domain"
      ]

• src/core/runtime.js:1879-1966 (handler)

  Handler: The actual execution handler for DNS_getDNSRecordsV1 is the executeApiCall method in MCPServer. Since this tool has custom=false (not in the switch/case), it goes through executeApiCall which substitutes the {domain} path parameter from the request params, then makes a GET request to /api/dns/v1/zones/{domain} with the domain as a query parameter.

  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}`;
      } 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;
        config.headers["Content-Type"] = "application/json";
      }
  
      this.log('debug', "Request config:", {
        url: config.url,
        method: config.method,
        params: config.params,
        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 responseData = error.response?.data;
        const responseStatus = error.response?.status;
  
        this.log('error', 'API Error Details:', {
          status: responseStatus,
          data: typeof responseData === 'object' ? JSON.stringify(responseData) : responseData
        });
  
        // Rethrow with more context for better error handling
        const detailedError = new Error(`API request failed with status ${responseStatus}: ${errorMessage}`);
        detailedError.response = error.response;
        throw detailedError;
      }
  
      throw error;
    }
