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)
