Use the clinicaltrials_* tools to access the ClinicalTrials.gov registry — public, read-only, ~577K studies. Studies are addressed by NCT ID (NCT followed by 8 digits). Field names for the fields, advancedFilter, and sort parameters are PascalCase leaves (NCTId, OverallStatus, EnrollmentCount) — call clinicaltrials_get_field_definitions to discover them and clinicaltrials_get_field_values for valid enum values. Typical workflow: clinicaltrials_search_studies (pass fields to trim ~70KB records) → clinicaltrials_get_study_record → clinicaltrials_get_study_results (only when hasResults=true). Use clinicaltrials_get_study_count for cheap breakdowns and clinicaltrials_find_eligible for patient matching.
