Which carriers are supported?

How is the dimensional weight calculated?

It calculates the volume of the package and divides it by a carrier-specific divisor (e.g., 139 for FedEx/UPS/DHL, 166 for USPS).

Billable weight is the higher value between the package's actual physical mass and its calculated dimensional weight.

This MCP server provides essential tools for logistics professionals to manage shipping costs by calculating volumetric weights. Using the get_all_carrier_dim_weights tool, you can determine how much space a package occupies across carriers like FedEx, UPS, DHL, and USPS. The resolve_billable_weight tool helps identify the final weight used for invoicing by comparing actual mass to dimensional weight, while calculate_weight_gap quantifies the extra cost incurred from low-density shipments.
