Parcel Shipping Rates

No install snippet on purpose. A working MCP config is a command, its arguments and an environment block — the last two are where API keys live, so this catalogue never stores them and cannot publish them. Follow the link above for the authors' own instructions.

The API provides live parcel rates for USPS, UPS, FedEx, and DHL Express by describing an item in plain words. The service automatically estimates packed box size and weight from an item description, or accepts exact dimensions to skip the estimate. Each rate response includes three separate figures: the checkout total, the carrier cost, and the SMKlog fee.

The service integrates with MCP-capable assistants via a streamable HTTP endpoint. The create_checkout_link tool generates a hosted checkout page where a human confirms and pays, preventing agents from paying autonomously. The service includes a monthly shipping price index tool that provides reference numbers without consuming quote allowance.

Quoting and payment sessions are open without an account or key, but are rate limited per client.
