Connect Public Research (Japan) to Claude
Query Public Research (Japan) directly from Claude. Arlet links the two through one MCP connection and takes care of API keys.
An index of reports and announcements published by public institutions of Japan (#1258), built from their official feeds. Nothing is stored server-side (fetched on call, short-lived memory cache only).
Cards are split by which institution published a report: this card carries only public institutions of Japan; other countries' institutions live on their own cards.
Tools:
- search_japan_public_reports: keyword search (omit query for newest first).
- fetch_report_content: always returns available=false plus the official URL (metadata-only index).
Institutions covered (7; feeds and each institution's terms of use verified against primary sources on 2026-08-12):
