Connects to EasyPost shipping platform. Muse can rate shipments, purchase and refund labels, track packages in real time, and verify delivery addresses for accuracy.

Example request: "Buy a shipping label for a package I'm sending to a customer and track it until delivery."

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use EasyPost to help me. It is a free service with an MCP server at https://easypost.usefulapi.io/mcp. It does not need an API key. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.

- easypost_create_shipment: Create a shipment from a to_address, from_address, and parcel, returning the available RATES from all enabled carriers.

- easypost_buy_shipment: PURCHASE a shipping label for a shipment at a chosen rate. WARNING: this CHARGES the EasyPost account balance and is irreversible except by requesting a refund (easypost_refund_shipment). Pick a rate_id from the rates returned by easypost_create_shipment or easypost_get_shipment.
- easypost_refund_shipment: Request a refund (void) of a purchased shipping label. WARNING: reverses a purchase; approval depends on the carrier and label age. API: POST /shipments/{id}/refund.
