Trade Preflight Gateway

A cross-border trade MCP server for pre-transaction checks on China to US and China to EU physical goods shipments.

Remote endpoint

What it does

Trade Preflight Gateway organizes a dated customs preflight before a transaction. It helps structure landed cost, tariff, de minimis, and import-requirement questions for a narrow China to US/EU corridor.

Tools:

  • trade_preflight - run a corridor preflight and return an evidence-aware status.
  • check_trade_requirements - check required trade and import fields for the selected corridor.
  • normalize_supplier_quote - normalize supplier quote inputs for comparable landed-cost review.
  • compare_preflight_quotes - compare preflight quote records while preserving uncertainty.

Scope

  • China to United States and China to European Union corridors.
  • Low-regulation physical goods and pre-transaction planning.
  • Landed-cost structure, customs preflight, tariff and de minimis questions, and missing-data detection.

Safety and limits

Estimates only. Uncertain HS classification, tariff, PGA, antidumping/countervailing-duty, or other regulated cases return NEEDS_MORE_DATA or MANUAL_REVIEW rather than a definitive result. This server is not customs, tax, import, export, or legal advice. Confirm requirements with the relevant authorities or a qualified professional before shipping or paying.

This repository contains public documentation and metadata only. It does not contain private business code, credentials, D1 data, or internal paths.

Connection
