# Japan Statistics (e-Stat) MCP Server (`aulvem/estat-mcp-apify`) Actor Pay-per-call MCP server giving AI agents structured access to Japan's official government statistics (labor, prices, population). LLM-optimized JSON with full source attribution. - **URL**: https://apify.com/aulvem/estat-mcp-apify.md - **Developed by:** [Aulvem](https://apify.com/aulvem) (community) - **Categories:** AI, Developer tools - **Stats:** 1 total users, 0 monthly users, 0.0% runs succeeded, NaN bookmarks - **User rating**: No ratings yet ## Pricing from $0.01 / 1,000 results This Actor is paid per event and usage. You are charged both the fixed price for specific events and for Apify platform usage.

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases. In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours, and optionally produces a well-defined JSON output, datasets with results, or files in key-value store. In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server. Actors are written with capital "A". ## How to integrate an Actor? If asked about integration, you help developers integrate Actors into their projects. You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready. The best way to integrate Actors is as follows. In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md): ```bash npm install apify-client ``` In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md): ```bash pip install apify-client ``` In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md): ````bash # MacOS / Linux curl -fsSL https://apify.com/install-cli.sh | bash # Windows irm https://apify.com/install-cli.ps1 | iex ```bash In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md). If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md). For usage examples, see the [API](#api) section below. For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt). # README ## Japan Statistics (e-Stat) MCP Server A pay-per-call MCP server giving AI agents structured access to Japan's official government statistics. Query labor force data, consumer prices, and population estimates with sub-second latency, LLM-optimized JSON responses, and full source attribution. ### What's available (v1) Three high-demand domains, five typed tools: - **search_indicator** — find statistical indicators by keyword (English or Japanese) - **get_timeseries** — fetch period-by-period values for an indicator - **list_categories** — show available domains - **get_metadata** — collection methodology, definitions, methodology notes - **compare_periods** — absolute and percentage change between two periods Roadmap Q3 2026: 6+ domains including National Accounts, Trade Statistics, Industrial Production. ### Why use this Actor - Sub-300ms warm latency, p50 200ms (KV-cached at the upstream layer) - LLM-friendly: schema designed for agent consumption, not human dashboards - Source-of-truth: every datapoint carries the e-Stat publication metadata and citation URL - No equivalent currently exists in English-language MCP marketplaces Data is sourced directly from the Statistics Bureau of Japan, e-Stat. This Actor proxies a hosted MCP server with full source attribution per e-Stat open-data terms. ### Pricing Pay Per Event: **$0.012 per tool call**. `initialize`, `tools/list`, and notifications are free. Only `tools/call` invocations are billed. ### How to connect Once the Actor is running in Standby mode, connect any MCP-capable client to: ```` https://aulvem--estat-mcp-apify.apify.actor/mcp ```` with `Authorization: Bearer ` to authorize Apify-side billing. #### Example: Claude Desktop config ```json { "mcpServers": { "estat": { "command": "npx", "args": [ "mcp-remote", "https://aulvem--estat-mcp-apify.apify.actor/mcp", "--header", "Authorization: Bearer ${APIFY_API_TOKEN}" ], "env": { "APIFY_API_TOKEN": "" } } } } ```` ### Output Tool responses are JSON. Example for `get_timeseries`: ```json { "indicator": "Unemployment rate (seasonally adjusted)", "unit": "percent", "frequency": "monthly", "values": [ { "period": "2025-01", "value": 2.5 }, { "period": "2025-02", "value": 2.4 } ], "source": { "publisher": "Statistics Bureau of Japan", "dataset": "Labour Force Survey", "url": "https://www.e-stat.go.jp/..." } } ``` ### FAQ **Is it legal?** Yes. e-Stat data is published under open-data terms. This server attaches source attribution to every response. **Affiliation?** Unofficial. Not affiliated with the Statistics Bureau of Japan or Anthropic. **Support / feedback?** Open an issue on the Actor's Issues tab. # Actor input Schema ## Actor input object example ```json {} ``` # API You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup. ## JavaScript example ```javascript import { ApifyClient } from 'apify-client'; // Initialize the ApifyClient with your Apify API token // Replace the '' with your token const client = new ApifyClient({ token: '', }); // Prepare Actor input const input = {}; // Run the Actor and wait for it to finish const run = await client.actor("aulvem/estat-mcp-apify").call(input); // Fetch and print Actor results from the run's dataset (if any) console.log('Results from dataset'); console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`); const { items } = await client.dataset(run.defaultDatasetId).listItems(); items.forEach((item) => { console.dir(item); }); // 📚 Want to learn more 📖?
