快递100 through MCP

快递100 runs an official MCP server for its tracking API: a tracking number in, the courier's events out, for 3000-odd carriers. Configured, its tools appear to you as kuaidi100__*. No app, no screen: "到哪了" is one tool call. It is a paid API with a free trial; every new tracking number costs the user one query from their plan (the same number asked again within 40 days is free), so do not poll a parcel in a loop.

Is it there?

Look for kuaidi100__query_trace in your tools (the tools list is the only place it can be: no shell command or script to check). If it is not there, say so in one line, give the user the lines to add, and stop; no browsing 快递100's website instead:

[[mcp.servers]]
name = "kuaidi100"
url = "https://api.kuaidi100.com/mcp/streamable?key={{vault:KUAIDI100_KEY}}"   # the 授权 key from api.kuaidi100.com 企业管理后台
risk = "safe"
egress = true
reads_private_data = true

and nanomuse vault set KUAIDI100_KEY. The same server runs locally from npx -y @kuaidi100-mcp/kuaidi100-mcp-server with env = { KUAIDI100_API_KEY = "{{vault:KUAIDI100_KEY}}" } when the user prefers nothing in a URL.

The tools

• kuaidi100__query_trace: the events of a parcel, kuaidi_num (the tracking number) and phone, required only for 顺丰 numbers (they start with SF; the sender's or receiver's phone, the last four digits are enough), empty otherwise. The carrier is recognised from the number.
• kuaidi100__estimate_time: the expected delivery time of a shipment not yet sent: kuaidi_com (the courier's lower-case code: shunfeng, jd, zhongtong, yuantong, yunda, shentong, ems, debangkuaidi, jtexpress …), from_loc and to_loc down to the district (广东省深圳市南山区), order_time (yyyy-MM-dd HH:mm:ss, optional) and exp_type (标准快递).
• kuaidi100__estimate_time_with_logistic: when a parcel already on its way will arrive: the same courier and addresses plus logistic, the events from query_trace as a JSON array of {time, context}.
• kuaidi100__estimate_price: what it would cost, kuaidi_com, send_addr, rec_addr (province and city at least), weight in kg.

Tool arguments may differ between server versions; read the tool descriptions you were given rather than this list when they disagree.

How to answer

• A tracking number is in the user's message, their clipboard (the phone's device__clipboard_read), a 京东 or 淘宝 order the browser just read, or recall ("my 京东 parcel from Monday"). Do not ask for a number you can find.
• One call per parcel. Say where it is now and the last event's time in plain words ("昨晚 21:40 到了杭州转运中心，今天派送"), then the expected arrival when the events say it or the user asks (estimate_time_with_logistic with the events you just got). Skip the whole event list unless the user asks.
• A phone number the tool needs is private data; use the one the user gave or the one on the order, never guess one, and do not repeat it back in full.
• 无物流信息 usually means the courier has not scanned the parcel yet; say that, not that the number is wrong, unless the answer says so.
• For a price or a delivery-time estimate, take the user's addresses down to the city or district and a weight; ask once for whatever is missing.

With the other hands

• 快递100 + the browser: the order page (京东, 淘宝, 拼多多) has the tracking number; the browser tool reads it, this skill tracks it; no need to open the courier's site.
• 快递100 + reminders: "tell me when it is out for delivery" is a reminder or a trigger that asks again tomorrow morning, not a loop of queries today.
• 快递100 + the phone: the number from a text message (phone-messages) or the clipboard; a reminder or an alarm for the pick-up-point deadline through the device tools.

Finish

One or two lines per parcel: courier, where it is, when it should arrive. remember nothing about the parcel itself; do remember the user's usual delivery address once they state it, so estimates need no question.
