| description | Submit compact ClinicalTrials.gov API v2 requests for study search, metadata, enums, search areas, and field statistics. Use when a user wants concise ClinicalTrials.gov summaries |
Operating rules
- Use
scripts/clinicaltrials_client.py for all ClinicalTrials.gov v2 calls.
- Study searches are better with
max_items=10 and max_pages=1; only increase pages when the user explicitly wants more than the first page.
- Use targeted
params instead of broad unfiltered study dumps.
- Re-run requests in long conversations instead of relying on older tool output.
- Treat displayed
... in tool previews as UI truncation, not literal request content.
Execution behavior
- Return concise markdown summaries from the script JSON by default.
- Prefer
action=studies for search and action=metadata|search_areas|enums|stats_size|field_values|field_sizes for API introspection and field stats.
- If the user needs full pages or aggregated responses, set
save_raw=true and report the saved file path.
Input
- Read one JSON object from stdin.
- Required field:
action
- Supported actions:
studies, metadata, search_areas, enums, stats_size, field_values, field_sizes, request
- Optional fields:
path for action=request, params, max_items, max_depth, max_pages, timeout_sec, save_raw, raw_output_path
- Common ClinicalTrials.gov patterns:
{"action":"studies","params":{"query.cond":"prostate cancer","filter.overallStatus":"RECRUITING","pageSize":10},"max_items":10,"max_pages":1}{"action":"metadata"}{"action":"field_values","params":{"field":"protocolSection.identificationModule.organization.fullName"}}
Output
action=studies returns pages_fetched, next_page_token, count metadata, and compact records.- Other actions return either compact
records or a compact summary.
- Use
raw_output_path when save_raw=true.
- Failure returns
ok=false with error.code and error.message.
Execution
echo '{"action":"studies","params":{"query.cond":"prostate cancer","filter.overallStatus":"RECRUITING","pageSize":10},"max_items":10,"max_pages":1}' | python scripts/clinicaltrials_client.py
References
- No additional runtime references are required; keep the import package limited to this file and
scripts/clinicaltrials_client.py.
