常见问题
Plain Freight 安全吗？
它在 1 项适用的基础检查中通过了 1 项。我们没有阅读代码。在添加密钥或令牌之前，请先看看这个服务器要求哪些权限，并使用只具备所需权限的密钥。
它需要哪些密钥或代码？
注册中心没有列出必需的密钥，不过有些服务器会在首次使用时要求你登录。
它在我的电脑上运行还是在云端？
它在作者的云端运行。通过互联网连接，无需安装，但你发送的内容会经过作者的服务器。
它还在维护吗？
GitHub 仓库最后更新于–，最新版本（1.0.0）于2个月前进入注册中心。
哪些应用可以使用它？
支持 MCP 的应用，例如 Claude Desktop、Claude Code、Cursor 和 VS Code。它通过 URL 连接，所以接受远程 MCP 服务器的应用也可以使用，例如开启开发者模式的 ChatGPT。
有什么可以替代它？

Plain Freight MCP server
A hosted Model Context Protocol server that quotes real freight. Ask it what it costs to ship something from China to the United States and it returns an all-in delivered-duty-paid price from the same pricing engine a human customer is quoted from: freight, US customs clearance, import duty and delivery to a US door, in one number.
No API key. No signup. Nothing to install.
https://plainfreight.com/api/mcpTransport is Streamable HTTP, stateless, protocol version 2025-06-18 (also accepts 2025-03-26 and 2024-11-05).
Add it to a client
Claude Code:
claude mcp add --transport http plain-freight https://plainfreight.com/api/mcpClaude Desktop, Cursor, or anything reading a JSON config:
{"mcpServers": { "plain-freight": { "type": "http", "url": "https://plainfreight.com/api/mcp" } } }
Check it by hand:
curl -s -X POST https://plainfreight.com/api/mcp \-H "Content-Type: application/json" \ -H "Accept: application/json, text/event-stream" \ -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'
Tools
Five tools. Only generate_offer records anything; the other four only read. No tool books or charges anything.
| Tool | What it does |
|---|---|
estimate_price | A rough door to door cost in USD for air (and sea from 100 kg chargeable weight), from the same pricing engine. Needs weight_kg; product, carton sizes (carton_length_cm, carton_width_cm, carton_height_cm, carton_count) or total_cbm sharpen it. Returns the chargeable weight used (the greater of actual weight and carton volume in cm3 / 6,000), transit estimates and whether US import duty is included. Records nothing, contacts no one, needs no email. Goods that need a person to review them get no figure. |
check_goods | Says whether a product (product, in the user's words) is priced at once or reviewed by a person first (for example batteries, chemicals, food, cosmetics, seeds, vapes or weapons), with a plain explanation and what documents to have ready. Same screen as generate_offer, so it predicts what an offer will do. Records nothing. Not legal or customs advice. |
generate_offer | The firm offer. Needs product and weight_kg (0.1 to 2000); dimensions, origin, destination_zip, urgency, email, name and notes all improve the answer. Pass carton sizes when you have them: for light bulky cargo the volumetric weight sets the price, not the scale weight. Each call records a quote request, and if an email is given the written offer is mailed there once the second check settles (at most one offer email per address per day). Returns the options, a quote_id and a link to a booking form on plainfreight.com prefilled with the shipment. |
check_offer_status | Polls an offer by quote_id until settled is true. Every quote gets a second check, which can add follow-up questions, change the options, or set needs_review. Read-only. |
track_shipment | Reads the live record for a booked shipment from its tracking_link (https://plainfreight.com/track/ , or the bare token): current stage on the 10-stage lifecycle, route and dated events. Read-only. |
Booking happens outside the chat: the user opens the prefilled booking form, replies to the offer email, or writes to hello@plainfreight.com quoting the quote_id. Nothing is paid before the goods are weighed at the warehouse.
Two behaviours worth knowing before you build on it:
- `needs_review` means the prices are withheld on purpose. The goods look restricted (batteries, food, chemicals) and a person has to clear them first. Do not present a number to the user in that case; Plain Freight follows up by email.
- The tracking token is the credential. Anyone holding the link can read that shipment, and the record deliberately excludes cost and margin fields.
Rate limits: 20 offers per hour per IP, 4 per email address, 30 across all agents per hour. For bulk or programmatic access, email hello@plainfreight.com.
There is also a plain REST version of the same pricing call at POST https://plainfreight.com/api/v1/offer, described in openapi.json, and human documentation at plainfreight.com/for-agents.
Published reference data
The same engine feeds three pages that are free to cite, with CSV and JSON where it makes sense:
- China to USA shipping price index: dated door-to-door prices at twelve weights from 0.5 kg to 1,000 kg, with duty status and transit time on every row.
- Chargeable weight reference: what fifteen real cartons bill, and the same cartons at three divisors.
- US import rules timeline: every de minimis and entry change since May 2025 with its Federal Register citation.
The price-index data is also published as a dataset at plainfreight-com/china-usa-freight-price-index.
What Plain Freight is
A China to USA freight agency for small importers: one all-in DDP price on shipments from 100 g to 2,000 kg, quoted before pickup. Plain Freight is a trading name of Fisto LLC, a Wyoming limited liability company. The price does not include cargo insurance, which the customer arranges separately.
Questions, or a shipment that needs a human: hello@plainfreight.com
