Perplexity

Spot stuck packages with the EasyPost MCP Server

The `list_in_transit_packages` tool identifies every shipment currently stuck between warehouses so you can update customers before they complain. Your agent scans the transit list, flags delays, and matches them against `list_active_trackers` to isolate carrier bottlenecks. Stop digging through shipping portals. Claude Desktop runs this MCP configuration locally via stdio or through a remote web connector. It pulls real-time carrier events directly into your chat, giving you the raw shipping data needed to solve delivery issues instantly.

Run carrier performance audits in Claude Desktop

The `quick_delivery_health_audit` tool generates a direct summary of your delivery success rates and active shipment volumes. Your agent evaluates current carrier performance by comparing live delivery timelines against your contracted service level agreements. You get a clear picture of which shipping lanes are failing. Claude Desktop presents these metrics as clean, actionable lists, allowing you to swap carriers or adjust shipping rules based on actual transit performance.

Pull live shipment rates and tracking data

The `get_shipment_details` tool extracts active rates and carrier options for any package ID in your system. Your agent inspects the cost breakdown, finds cheaper alternatives, and checks the status using `get_tracking_details` to verify the carrier actually received the package. This setup lets you verify shipping costs without opening a web browser or writing custom API scripts. You ask Claude Desktop to inspect a package, and it returns the exact pricing and carrier metadata on the spot.
