Implementation Reference

• src/index.ts:147-161 (registration)

  Tool registration in the listTools response, including name, description, and input schema definition.

  {
    name: 'validate_address',
    description:
      'Validate if a string is a valid Ethereum address format.',
    inputSchema: {
      type: 'object',
      properties: {
        address: {
          type: 'string',
          description: 'Address string to validate',
        },
      },
      required: ['address'],
    },
  },

• src/index.ts:482-511 (handler)

  The main tool handler in the CallToolRequestSchema switch statement. Validates input, calls the helper method, and formats the response.

  case 'validate_address': {
    const address = args?.address as string;
    if (!address || typeof address !== 'string') {
      throw new McpError(
        ErrorCode.InvalidParams,
        'address parameter is required and must be a string'
      );
    }
  
    const isValid = aaveClient.isValidAddress(address);
  
    return {
      content: [
        {
          type: 'text',
          text: JSON.stringify(
            {
              address,
              isValid,
              message: isValid
                ? 'Valid Ethereum address format'
                : 'Invalid Ethereum address format',
            },
            null,
            2
          ),
        },
      ],
    };
  }

• src/aave-client.ts:344-346 (helper)

  Core helper method that performs the actual Ethereum address validation using ethers.js utility.

  isValidAddress(address: string): boolean {
    return ethers.isAddress(address);
  }
