dsh-kuajing

A cross-border sellers day is chopped up by a dozen small tasks: hunting an HS code, double-checking an IBAN, rendering an invoice PDF, and confirming whether your independent site actually loads from inside mainland China. dsh-kuajing folds eleven live web tools into one conversation so the whole chain from product classification to document output no longer requires tab-hopping.

The toolkit hits the key touchpoints of trade operations: it recommends a US 10-digit HTS code from product name, attributes and category, returning confidence scores and a reasoning chain positioned as a starting point for a customs broker rather than a final filing; renders structured data into a professional PDF invoice; fetches live exchange rates; validates IBANs via ISO 13616 MOD-97; checks EAN-13, UPC-A and EAN-8 check digits with GS1 prefix identification; converts amounts to English words for letters of credit and invoices; and probes your site from a real China Mobile backbone egress, reporting HTTP status, latency and the IP that Chinese DNS resolves to — something no overseas VPS can infer. Excel read and write are included for batch data work, and a natural-language router accepts a task description in any language and returns the exact tool with a ready-to-run call.

Built for cross-border e-commerce operators, trade sales reps, independent-site sellers, and anyone assisting with customs documentation. Every call runs server-side; the local package ships a single MCP client config row, with no code execution, no filesystem or shell access, and no document retention. The free tier requires no signup, per-call pricing is transparent, and failed calls are never charged. If your workflow keeps getting interrupted by questions like which chapter a code actually belongs to, whether a digit in the IBAN got transposed, or why a customer says the site will not load while your own monitor shows green, this pack is worth a try.
