README (SKILL.md)
e-Stat: Japanese Government Statistics API
Search and fetch official statistics from e-Stat (政府統計の総合窓口), Japan's central portal for government open data. Covers population, GDP, CPI, trade, labor, and 3,000+ statistical tables from all ministries.
Use Cases
- Look up Japan's population by prefecture and year
- Compare CPI (消費者物価指数) trends over time
- Fetch GDP and national accounts data for economic analysis
- Retrieve trade statistics (輸出入) by commodity or country
- Access labor force survey data (完全失業率, 就業者数)
Commands
Search for statistics
# Search by keyword (Japanese or English)
estat-mcp search 人口
estat-mcp search "消費者物価指数" --limit 10
estat-mcp search GDP --format json
Fetch statistical data
# Basic data fetch
estat-mcp data 0003410379
# With filters (area=Tokyo, year=2024)
estat-mcp data 0003410379 --cd-area 13000 --cd-time 2024000
# JSON output for programmatic use
estat-mcp data 0003410379 --limit 50 --format json
Test connectivity
estat-mcp test
Filter Parameters
--cd-tab— Table item code (表章事項コード)--cd-time— Time code (時間軸事項コード). Example:2024000for 2024--cd-area— Area code (地域事項コード). Example:13000for Tokyo--cd-cat01— Classification code 01 (分類事項01コード)
Common Statistics
Find table IDs via estat-mcp search:
| Topic | Search keyword | Examples |
|---|---|---|
| Population (人口) | 人口推計 |
Total, by age, by prefecture |
| CPI (物価) | 消費者物価指数 |
Monthly/annual price indices |
| GDP (国民経済計算) | 国民経済計算 |
Nominal/real GDP, expenditure |
| Labor (労働) | 労働力調査 |
Unemployment, employment |
| Trade (貿易) | 貿易統計 |
Imports/exports by country |
Workflow

Setup
- Requires
ESTAT_APP_IDenvironment variable - Free API key registration: https://www.e-stat.go.jp/api/api-info/use-api
- Rate limited to 1 req/sec
- Python package:
pip install estat-mcporuv tool install estat-mcp
Usage Guidance
This skill appears coherent for accessing Japan's e-Stat API. Before installing: (1) verify the estat-mcp package source (PyPI or an official repository/GitHub) so you know what code will be installed; (2) only provide a valid e-Stat API key (ESTAT_APP_ID) and avoid sharing other secrets; (3) after install, run `estat-mcp test` and inspect what network endpoints the binary calls if possible; (4) if you want stronger assurance, review the package code or use a sandboxed environment. Note that the agent may invoke the skill autonomously (normal behavior), so consider whether you want that enabled for this agent.
Capability Analysis
Type: OpenClaw Skill
Name: estat-mcp
Version: 0.2.2
The skill bundle is benign. It describes a legitimate purpose: fetching Japanese government statistics using the `estat-mcp` tool. The `SKILL.md` file provides standard instructions for the OpenClaw agent to install the `estat-mcp` Python package via `uv` and requires an `ESTAT_APP_ID` environment variable, which is typical for API-based tools. There is no evidence of prompt injection with malicious intent, data exfiltration, unauthorized execution, or other harmful behaviors within the provided files.
Capability Assessment
Purpose & Capability
Name/description (e-Stat API client) match the declared binary (estat-mcp) and the documented commands. Requiring an e-Stat API key (ESTAT_APP_ID) is expected for this purpose.
Instruction Scope
SKILL.md contains only usage instructions for the estat-mcp CLI, the required ESTAT_APP_ID, and install hints (pip/uv). It does not instruct reading unrelated files, sweeping environment variables, or sending data to unexpected endpoints.
Install Mechanism
Install spec uses a 'uv' package installer to provide the estat-mcp binary and SKILL.md also mentions 'pip install estat-mcp'. Installing a single named package that creates the expected binary is reasonable, but 'uv' is less common than pip/standard package managers — verify the package source before installing.
Credentials
Only one env var is required: ESTAT_APP_ID, which is the e-Stat API key documented in the SKILL.md. No unrelated credentials or config paths are requested.
Persistence & Privilege
Skill does not request permanent/always-on presence (always:false) and does not modify other skills or system-wide settings. Autonomous invocation is allowed by default (normal) and not by itself a concern.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install estat-mcp - After installation, invoke the skill by name or use
/estat-mcp - Provide required inputs per the skill's parameter spec and get structured output
