No MCP client? Call it directly: GET https://gateway.pipeworx.io/v1/tools/jp_umin_ctr_trial_search for the schema, then POST the same URL with its arguments for the data.

Search the UMIN Clinical Trials Registry (UMIN-CTR), run by the University Hospital Medical Information Network in Japan (a WHO primary registry, much used for Japanese investigator-initiated studies). English words matched against the scientific title, or against the condition with field=“condition”, or a UMIN number. Each hit gives the UMIN number, title, condition, recruitment status (pending, recruiting, no_longer_recruiting, complete …), disclosure date and record link. Up to 100 results a page (page, next_page, total_pages). Reads the English-language database only. No hit means none there, not that no such trial exists. Use jp_umin_ctr_trial_get for the full record. Example: query=“pembrolizumab”.

Parameters

Name	Type	Required	Description
`query`	string	yes	English words from the scientific title (or the condition), or a UMIN number such as UMIN000063513.
`field`	string	no	What the words are matched against (default title).
`page`	number	no	Result page, up to 100 a page (default 1); use next_page from the previous answer.
`limit`	number	no	Trials returned from the page (1-100, default 10).
