search_preprintsSearch bioRxiv/medRxiv preprints. Returns DOI, title, authors, abstract preview, category.
WHEN TO USE:
- Literature review and research discovery
- Finding recent research in specific fields
- Tracking new submissions by date or category
SEARCH METHODS (use only ONE):
- Date range: date_from + date_to (e.g., '2024-01-01' to '2024-06-30') - RECOMMENDED
- Recent days: recent_days=30 (last 30 days)
- Recent count: recent_count=50 (searches last ~90 days, returns up to 'limit' results)
IMPORTANT: All searches use date ranges internally. recent_count searches a 90-day window. If no search method specified, defaults to last 60 days.
SERVERS:
- 'biorxiv': Biological sciences (default)
- 'medrxiv': Medical/health sciences
CATEGORIES (27 available): biochemistry, bioinformatics, cancer biology, cell biology, genetics, genomics, immunology, microbiology, molecular biology, neuroscience, and 17 more. Use get_categories tool for full list.
LIMITATIONS:
- NO keyword/text search - filter by category and date only
- Results are NOT peer-reviewed preprints
EXAMPLES:
- Last 30 days of neuroscience: recent_days=30, category='neuroscience'
- Cancer biology Q1 2024: date_from='2024-01-01', date_to='2024-03-31', category='cancer biology'
PAGINATION: Use cursor for next page (cursor=100 for results 100-199)
RELATED: get_preprint (full details by DOI), get_categories (list all categories)
-
get_preprintGet complete metadata for a specific preprint by DOI.
WHEN TO USE:
- You have a DOI and need full details
- Need abstract, authors, PDF URL, funding info
- Checking if preprint was published in a journal
RETURNS: title, all authors, corresponding author + institution, full abstract, category, license, version, PDF URL, web URL, funding details, published DOI (if available)
DOI FORMATS (all accepted):
- '10.1101/2024.01.15.123456'
- ''
SERVERS:
- 'biorxiv': For bioRxiv preprints (DOI contains biorxiv dates like 2024.01.15)
- 'medrxiv': For medRxiv preprints
IMPORTANT: Preprints are NOT peer-reviewed
RELATED: search_preprints (find DOIs), search_published_articles (find journal version)
-
get_categoriesList all 27 bioRxiv subject categories for filtering searches.
WHEN TO USE:
- Before search_preprints to see valid category values
- To understand research area classifications
RETURNS: Category names and API-compatible format (e.g., 'cancer biology' -> 'cancer_biology')
FULL LIST: animal behavior and cognition, biochemistry, bioengineering, bioinformatics, biophysics, cancer biology, cell biology, clinical trials, developmental biology, ecology, epidemiology, evolutionary biology, genetics, genomics, immunology, microbiology, molecular biology, neuroscience, paleontology, pathology, pharmacology and toxicology, physiology, plant biology, scientific communication and education, synthetic biology, systems biology, zoology
-
search_published_preprintsFind preprints that have been published in peer-reviewed journals.
WHEN TO USE:
- Track which preprints became journal articles
- Find the peer-reviewed version of a preprint
- Analyze preprint-to-publication patterns
- Filter articles by whether they were published by a specific journal
SEARCH METHODS (use only ONE):
- Date range: date_from + date_to
- Recent count: recent_count=50
- Recent days: recent_days=30
FILTERS:
- include_details: True for full metadata (slower), False for summary (faster)
- publisher: Filter by DOI prefix (e.g., '10.1038' for Nature) - see below
COMMON PUBLISHER PREFIXES:
- '10.1038' - Nature Publishing Group
- '10.1126' - Science/AAAS
- '10.1016' - Elsevier
- '10.1371' - PLOS
- '10.7554' - eLife
- '10.1073' - PNAS
EXAMPLE: Find recently published medRxiv papers: server='medrxiv', recent_days=30
-
search_by_funderSearch for preprints funded by a specific organization using ROR ID.
WHEN TO USE:

- Monitor grant-funded research areas
REQUIRES: funder_ror_id (9-character ROR ID)
COMMON FUNDER ROR IDS:
- '021nxhr62' - NIH (National Institutes of Health)
- '01cwqze88' - NSF (National Science Foundation)
