Overview

AI-generated overview

Lets an assistant compute China export quotes, tax refunds, container loading and FX settlement, and look up HS-code refund rates and public datasets.

What you can do
Offers a set of China export calculators: FOB/CIF/CFR quotes with profit, CBM and chargeable weight, unit conversion, RMB central parity and FX settlement cost, shipping mark and proforma invoice generation, export tax refund, and container loading. It also looks up export refund rates by customs (HS) code, lists the site's public datasets with versions and paged rows, and builds a buyer-facing quote with structured data and plain text.
When to use it
Use it when handling China export work and needing quick figures for quotes, tax refunds, container loading or FX settlement, or when looking up refund rates for an HS code and dataset versions.
Requirements
Remote MCP endpoint at chukoudan.com; no local package. Needs network access. No authentication, environment variables or headers are declared.
Before you install
Refund-rate and exchange-rate data come from the site, are not an official channel, and are for reference only; official publications prevail. The quote tool produces internal data with the seller's cost, refund and profit that must not be sent to the buyer. Tools instruct against inventing figures or dates.

Installation

In SourceWeft

  1. Open 出口单 chukoudan in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.chukoudan%2Fchukoudan/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

lookup_refund_rate

出口退税率查询

查询一个海关编码（HS 编码、商品编码，8 位或 10 位，可带点）在出口退税率文库中的出口退税率（退税率、征税率），用于“帮我查一下海关编码 … 的出口退税率”这类问题。返回该编码的各个时期，并标出适用的一期：给出 export_date（报关单出口日期，不是开票日期）就按那一天；没给就按今天（北京时间），回答里的 lookup.in_force_on 写明用的是哪一天。用户问“现在”“今天”时不要填 export_date，绝不要自己猜今天的日期；回答时说明是按哪一天标出的。编码不在文库中时返回 found: false 和相近编码，绝不编造税率。本站非官方渠道，仅供参考，以官方公布为准，请把答案里的 notes 一并转告用户。 Look up the export VAT refund rate (出口退税率, 退税率) of ONE customs / HS code (海关编码, 商品编码; 8 or 10 digits, dots allowed, e.g. 8506101110) in the 出口退税率文库. Use it for "帮我查一下海关编码 … 的出口退税率" / "what is the export refund rate of HS code …". Returns every period of the code (refund rate, levy rate 征税率, from, to) and the period in force on one day: export_date when given, otherwise today by the Beijing calendar (lookup.in_force_on names the day). The rate that counts is the one on the export date of the customs declaration (报关单出口日期), not the invoice date: for “now” or “today” leave export_date out and never guess today’s date; say in your reply which day the period was marked for. An unknown code answers found: false with nearby codes, never a rate. Reference data from this site, not the official channel; the official publication prevails. Pass on the notes in the answer.

Parameterscoderequiredexport_date

make_quote

生成报价单

按报价工具的输入和卖方的条款，生成一份发给买方的报价单：quote 是结构化数据（https://chukoudan.com/schemas/quote/v1.json，只有价格和条款，带 digest 和汇率依据，买方可核对），text 是可直接发出的纯文本（语言按 language），internal 是卖方自己的成本、退税和利润，只给卖方看，绝不发给买方。本站不保存任何内容。 Make a quote for a buyer from the quote calculator’s inputs (pricing) and the seller’s terms (quote): `quote` is the quote as data (schema https://chukoudan.com/schemas/quote/v1.json; prices and terms only, with a digest and the dated rate it rests on, so the buyer can check it), `text` is the same quote as plain text ready to send, and `internal` holds the seller’s own cost, refund and profit: for the seller only, NEVER send it to the buyer. Leave pricing.fxRate out to use the day’s RMB central parity. Nothing is stored.
