Global Logistics (AfterShip labels with your own carrier accounts) MCP server

Compare live shipping rates across the carriers bound to a merchant AfterShip shipper account (UPS / USPS / FedEx / DHL / Ninja Van / J&T and more). IMPORTANT: shipper_account_id is the MERCHANT'S OWN carrier account (their own contract/rates), which they bound inside AfterShip / admin.postmen.com — this server never owns carrier accounts. Pass a to/from address and a parcel (weight + optional dimensions); returns a list of available service_type values with each total_charge (amount + currency), delivery_date and transit_time. Feed the service_type you want into create_label. Bring-your-own key via header x-aftership-key; x-aftership-env sandbox (default, free) or production. This call never buys anything.

Buy a shipping label for a chosen service_type through the merchant's AfterShip shipper account, and return the printable label file url + tracking_number. First call quote_rates to see available service_type values, then pass that service_type here with the SAME shipper_account_id, addresses and parcel. Before purchasing, this server re-quotes the exact charge and applies the owner policy guardrails (x-agentpay-max-amount / x-agentpay-approval-above) — over the approval threshold returns an unsigned draft and buys nothing. Default env is sandbox (x-aftership-env), which generates real labels at ZERO cost; send x-aftership-env: production to buy real postage. The cost lands on the merchant's own carrier contract, not this server.

Cancel / void a shipping label created via create_label, by its label_id. If the label was never used, the carrier voids it so the merchant is not charged (voidability and windows depend on the carrier). Returns cancel_status: cancelled, pending (carrier still processing) or failed. Idempotent — cancelling an already-cancelled label is safe.

NOT SUPPORTED by this server. AfterShip's Shipping (Postmen) API — which powers this server's rate/label/cancel tools — has no parcel-tracking endpoint. Live parcel tracking is a SEPARATE AfterShip product: the AfterShip Tracking API (https://www.aftership.com/docs/tracking). To follow a parcel, use the carrier's own tracking or the AfterShip Tracking API with the tracking_number that create_label returned. This tool returns a structured not_supported result explaining that (it never errors).
