`list_data_catalog`

Pack: estat-japan · Endpoint: https://gateway.pipeworx.io/estat-japan/mcp

Browse the e-Stat high-level data catalog (dataset/table groupings) with an optional free-text filter. Returns catalog entries with dataset IDs, names, and organization metadata. This endpoint is slow at e-Stat and often exceeds its 35s budget, in which case it returns {found:false, reason:“upstream_timeout”}; search_stats answers “which Japanese statistics table covers X” faster. Requires _apiKey.

Parameters

Name	Type	Required	Description
`query`	string	no	Optional free-text filter, Japanese or English
`limit`	number	no	Page size, 1-100. Defaults to 20 when omitted, so a bare call is already bounded.
`start_position`	number	no	1-based offset (default 1)
`lang`	string	no	J (Japanese, default) \| E (English)
`data_type`	string	no	Restrict to one file format: XLS \| CSV \| PDF \| XML \| XLS_REP \| DB
`survey_years`	string	no	Survey period: yyyy, yyyymm, or yyyymm-yyyymm
`stats_code`	string	no	Government statistics code, e.g. “00200521” (population census)
`stats_field`	string	no	Statistical field code, 2 digits (major) or 4 digits (minor)
