Capacidades

Herramientas

41 herramientas
autocomplete_papers
Semantic Scholar: autocomplete paper titles for a partial query (fast type-ahead).
Esquema de entrada 
{'type': 'object', 'title': 'autocomplete_papersArguments', 'required': ['query'], 'properties': {'query': {'type': 'string', 'title': 'Query'}}}
extract_pdf
Extract a PDF to clean Markdown/LaTeX text via MinerU (great for papers behind no open-access full text — give the user's PDF and get readable text back). Provide pdf_url (downloaded server-side, SSRF-guarded) OR pdf_base64. formula/table toggle math/table reconstruction. Returns {task_id, status, cached, content, chars}: a recently-seen (cached) or small PDF comes back with `content` in one call; a fresh PDF (MinerU is GPU-heavy, minutes) returns status='running' + a task_id — then call extract_pdf_result(task_id) to fetch the text.
Esquema de entrada 
{'type': 'object', 'title': 'extract_pdfArguments', 'properties': {'table': {'type': 'boolean', 'title': 'Table', 'default': True}, 'formula': {'type': 'boolean', 'title': 'Formula', 'default': True}, 'pdf_url': {'type': 'string', 'title': 'Pdf Url', 'default': ''}, 'pdf_base64': {'type': 'string', 'title': 'Pdf Base64', 'default': ''}}}
extract_pdf_result
Fetch the result of an extract_pdf job by task_id. Returns {task_id, status, content, chars}: `content` is the extracted text once status='done'; while still 'running' content is null — call again shortly. Results expire server-side, so fetch reasonably soon.

recommend_papers_for_paper
Semantic Scholar: recommend papers similar to one paper. pool='recent' (last open corpus) or 'all-cs' (all of CS). If the 'recent' pool yields nothing (common for older papers), it automatically retries the 'all-cs' pool.
Esquema de entrada 
{'type': 'object', 'title': 'recommend_papers_for_paperArguments', 'required': ['paper_id'], 'properties': {'pool': {'type': 'string', 'title': 'Pool', 'default': 'recent'}, 'paper_id': {'type': 'string', 'title': 'Paper Id'}, 'max_results': {'type': 'integer', 'title': 'Max Results', 'default': 10}}}

search_all
Aggregated search across arXiv, Semantic Scholar and OpenAlex at once. Fans out concurrently, de-duplicates the same work across corpora (by DOI or title) and re-ranks with Reciprocal Rank Fusion, so papers found by several sources rank highest. Each hit lists which `sources` found it and an `ids` map ({source: id}) you can pass to get_paper / read_paper / the citation tools. Prefer this over search_papers for a broad lookup.
Esquema de entrada 
{'type': 'object', 'title': 'search_allArguments', 'required': ['query'], 'properties': {'query': {'type': 'string', 'title': 'Query'}, 'sources': {'type': 'string', 'title': 'Sources', 'default': 'arxiv,semanticscholar,openalex'}, 'per_source': {'type': 'integer', 'title': 'Per Source', 'default': 0}, 'max_results': {'type': 'integer', 'title': 'Max Results', 'default': 10}}}
search_authors
Semantic Scholar: search for authors by name; returns profiles with h-index and paper/citation counts.
Esquema de entrada 
{'type': 'object', 'title': 'search_authorsArguments', 'required': ['query'], 'properties': {'query': {'type': 'string', 'title': 'Query'}, 'start': {'type': 'integer', 'title': 'Start', 'default': 0}, 'max_results': {'type': 'integer', 'title': 'Max Results', 'default': 10}}}
search_by_author
Find papers by a specific author, newest first.
Esquema de entrada 
{'type': 'object', 'title': 'search_by_authorArguments', 'required': ['author'], 'properties': {'start': {'type': 'integer', 'title': 'Start', 'default': 0}, 'author': {'type': 'string', 'title': 'Author'}, 'source': {'type': 'string', 'title': 'Source', 'default': 'arxiv'}, 'max_results': {'type': 'integer', 'title': 'Max Results', 'default': 10}}}
search_medical
Evidence-graded MEDICAL literature search (PubMed + Europe PMC). Unlike search_all (generic, ranks high-cited reviews/guidelines above trials), this filters by research type via PubMed Publication-Type tags and re-ranks by the evidence pyramid (meta-analysis / systematic review > RCT > cohort > ...), so the actual clinical trials surface first. Open-access full text is pulled from Europe PMC by PMID. `query` should be English keyword/boolean text (PubMed maps it); do natural-language/multilingual understanding upstream. Returns hits with pmid/doi/study_type/evidence_level/citations/abstract and, when open-access, fulltext.
Esquema de entrada 
{'type': 'object', 'title': 'search_medicalArguments', 'required': ['query'], 'properties': {'query': {'type': 'string', 'title': 'Query'}, 'year_from': {'type': 'integer', 'title': 'Year From', 'default': 0}, 'max_results': {'type': 'integer', 'title': 'Max Results', 'default': 10}, 'study_types': {'type': 'string', 'title': 'Study Types', 'default': 'rct,meta-analysis,systematic-review'}, 'fetch_fulltext': {'type': 'boolean', 'title': 'Fetch Fulltext', 'default': True}}}

search_papers_bulk
Semantic Scholar: bulk paper search (up to 1000 hits, sortable e.g. 'citationCount:desc' or 'publicationDate:desc', with a continuation token). Filters: fields_of_study, year (e.g. '2020-2024'), venue, publication_types, open_access_pdf.
Esquema de entrada 
{'type': 'object', 'title': 'search_papers_bulkArguments', 'required': ['query'], 'properties': {'sort': {'type': 'string', 'title': 'Sort', 'default': ''}, 'year': {'type': 'string', 'title': 'Year', 'default': ''}, 'query': {'type': 'string', 'title': 'Query'}, 'token': {'type': 'string', 'title': 'Token', 'default': ''}, 'venue': {'type': 'string', 'title': 'Venue', 'default': ''}, 'max_results': {'type': 'integer', 'title': 'Max Results', 'default': 100}, 'fields_of_study': {'type': 'string', 'title': 'Fields Of Study', 'default': ''}, 'open_access_pdf': {'type': 'boolean', 'title': 'Open Access Pdf', 'default': False}, 'publication_types': {'type': 'string', 'title': 'Publication Types', 'default': ''}}}
search_snippets
