Calculating Totals & Formatting Dates

When connecting legacy or unoptimized API platforms to your AI Agents, you will frequently encounter datasets requiring mathematical computation or strict cryptographic formatting. Because LLMs inherently struggle to consistently execute deep variable math in a single prompt natively, you can explicitly offload this deterministic state processing to the HasMCP Goja backend explicitly.

​
Example: Calculating Inventory

var warehouse_total_value = 0;
 
// Calculate total price of all items effectively
input.inventory.forEach(function(item) {
  warehouse_total_value += (item.qty * item.price_per_unit);
});
 
// Return the final evaluated object directly
return {
  global_inventory_valuation: warehouse_total_value
};

​
Example: Standardizing Unix Timestamps

The following example parses an archaic API returning 1694200000 and normalizes the payload to strictly readable ISO8601 strings seamlessly: 
// Iterate the events recursively 
for (var i = 0; i < input.length; i++) {
  var rawUnix = input[i].server_startup_time;
 
  // JS evaluates unix timestamps in milliseconds 
  input[i].server_startup_time = new Date(rawUnix * 1000).toISOString();
}
 
return input;
This transforms raw bytes into 2023-09-08T19:06:40.000Z, providing the LLM agent flawless temporal reasoning proactively and securely.
