      if (!input.address) {
        return createErrorResponse("Address is required");
      }
  
      if (!input.position) {
        return createErrorResponse("Position is required");
      }
  
      const provider = getProvider();
      const storage = await provider.getStorageAt(input.address, input.position, input.blockTag);
  
      return createSuccessResponse(
      `Storage retrieved successfully
        Address: ${input.address}
        Position: ${input.position}
        Storage: ${storage}
      `);
    } catch (error) {
      return createErrorResponse(`Failed to get storage: ${(error as Error).message}`);
    }
