Overview

AI-generated overview

Remote MCP server for Japan customs trade statistics: search items, monthly series, partner breakdowns, rankings and country summaries, no API key.

What you can do
  • Look up items by name or 9-digit code and navigate the parent/child hierarchy
  • Get an item overview: 12-month value, YoY, 3-year change, main and growing partners, seasonality, concentration
  • Pull monthly series for value, quantity, unit price, YoY and MoM, with exports, imports and balance side by side
  • Break down an item by partner country with shares, and rank items by value, YoY or balance
  • Summarize overall trade with one country, and find new or surging partner markets
  • Check catalog, data coverage and latest months, and report data problems to the operator
When to use it
Useful when you need Japanese export or import figures by product code or partner country — market research, sourcing analysis, trend and seasonality questions — and want the assistant to query the data directly instead of reading published tables.
Requirements
A remote streamable HTTP endpoint; no API key, environment variables or headers are declared. Network access to the provider's endpoint is needed.
Before you install
The report_data_issue tool sends a message to the operator, so anything submitted there leaves your session. Figures come from the provider's own processing of Ministry of Finance customs data and may differ from official publications; check the flow of 9-digit codes, since export and import codes differ.

Installation

In SourceWeft

  1. Open Japan Trade Statistics (customs data) 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.washutrading.data%2Fjp-trade-stats/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

Item details: parent and child levels, unit, and the months covered. Use this to navigate the hierarchy. For an item's figures, partners and growth, use get_item_summary; use this to navigate parent and child levels. / 品目の詳細(上位・下位の区切り、単位、データのある期間)を返します。下位の品目をたどるときに使います。品目の金額・相手国・伸びなどの全体像は get_item_summary を使います。こちらは区切りの上下をたどるときに。

get_series

Get series

Monthly series for an item (value, quantity, unit price, YoY, MoM, preliminary/revised). With flow=both, exports, imports and the balance side by side. Chapters and sections start in 1988; 9-, 6- and 4-digit codes start in 2022. Use freq=year for long-term trends, or set from for older months (without from, months start in January 2022). Some import chapters and sections for April 2018–December 2019 return no value but gap="source" with an explanation, because the source e-Stat table lacks data. This does not mean there was no trade. / 品目の月ごとの推移(金額・数量・単価・前年比・前月比・速報/確報)。flow=both なら輸出・輸入・差し引きを並べます。類・部は1988年から、9桁・6桁・4桁は2022年から。長期の推移は freq=year、月ごとの過去分は from を付けます(from を省くと2022年1月から)。輸入の類・部の 2018年4月〜2019年12月の一部は、元データ(e-Stat の統計表)に欠けがあるため値を返さず gap="source" と説明文を返します。取引が無かったという意味ではありません。
