Shippo Shipping Skill

Setup

MCP server: https://app.getgram.ai/mcp/shippo-mcp-beta with header Mcp-Shippo-Merged-Api-Key-Header set to the SHIPPO_API_KEY environment variable.

Prerequisites: A valid Shippo API key and at least one carrier account (Shippo provides managed accounts for USPS, UPS, FedEx, DHL Express by default). See references/tool-reference.md for the full tool catalog.

Test vs live mode -- check the API key prefix before any purchase workflow:

• shippo_test_*: Labels are free. No real charges. Tracking uses mock numbers only.
• shippo_live_*: Real charges. Inform the user which mode they are in.

Test and live mode have completely separate data and object IDs.
