Implementation Reference

• src/tools.js:407-434 (handler)

  The main handler function for the 'thealeph_asn_regex' tool. It takes the ASN parameter, calls the API client to fetch regex patterns, formats the response with markdown, and handles errors.

  async asnRegex(params) {
    try {
      const { asn } = params;
      const result = await this.client.getASNRegex(asn);
  
      let response = `🔍 Regex Patterns for ASN ${asn}\n\n`;
  
      if (typeof result === 'object' && Object.keys(result).length > 0) {
        for (const [key, value] of Object.entries(result)) {
          if (Array.isArray(value)) {
            response += `**${key}:**\n`;
            value.forEach((pattern, idx) => {
              response += `  ${idx + 1}. \`${pattern}\`\n`;
            });
          } else {
            response += `**${key}:** \`${value}\`\n`;
          }
        }
      } else {
        response += 'No regex patterns available for this ASN.';
      }
  
      return response;
  
    } catch (error) {
      return `❌ Failed to retrieve ASN regex patterns: ${error.message}`;
    }
  }

• src/tools.js:101-109 (schema)

  Input schema definition for the tool, specifying that an 'asn' string parameter is required.

  inputSchema: {
    type: 'object',
    properties: {
      asn: {
        type: 'string',
        description: 'Autonomous System Number'
      }
    },
    required: ['asn']

• src/tools.js:98-110 (registration)

  Tool registration in getToolDefinitions(), including name, description, and input schema.

  {
    name: 'thealeph_asn_regex',
    description: 'Get regex patterns associated with an ASN for PTR record parsing',
    inputSchema: {
      type: 'object',
      properties: {
        asn: {
          type: 'string',
          description: 'Autonomous System Number'
        }
      },
      required: ['asn']
    }

• src/tools.js:240-241 (registration)

  Dispatch case in executeTool switch statement that routes to the asnRegex handler.

  case 'thealeph_asn_regex':
    return this.asnRegex(params);
