MCP server for ShipStation v2 (an Auctane product) — shipping rates, label purchase, and tracking. Use it to add fulfillment to a commerce agent downstream of an order source like Shopify.
When to use
Adding rate shopping, label creation, and tracking to an agent once an order exists upstream.
When not to use
Avoid if you require official vendor support, or carrier features beyond ShipStation's v2 coverage.
