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. ``` ### `get_openalex_citations` - The name "get_openalex_citations" says "get": a word for reading. - The description's first verb is "open": a word for a change.

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. ``` ### `search_papers` - The name "search_papers" says "search": a word for reading.

Description, as the server wrote it: ```untrusted-server-text Semantic Scholar: search INSIDE paper full text and return matching text snippets (not just titles/abstracts). ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `paper`: ```json { "permissions": { "allow": [ "mcp__paper__search_papers", "mcp__paper__search_all", "mcp__paper__search_medical", "mcp__paper__get_paper", "mcp__paper__search_by_author", "mcp__paper__list_recent", "mcp__paper__list_categories", "mcp__paper__read_paper", "mcp__paper__list_paper_sources", "mcp__paper__list_ocr_models", "mcp__paper__extract_pdf_result", "mcp__paper__get_paper_citations", "mcp__paper__get_paper_references", "mcp__paper__get_paper_authors", "mcp__paper__search_papers_bulk", "mcp__paper__get_papers_batch", "mcp__paper__search_authors", "mcp__paper__get_author", "mcp__paper__get_author_papers", "mcp__paper__get_authors_batch", "mcp__paper__search_snippets", "mcp__paper__list_dataset_releases", "mcp__paper__get_dataset_release", "mcp__paper__get_dataset_download_links", "mcp__paper__get_dataset_diffs" ], "ask": [ "mcp__paper__recognize_formula", "mcp__paper__recognize_table", "mcp__paper__lint_latex", "mcp__paper__extract_pdf", "mcp__paper__match_paper_title", "mcp__paper__autocomplete_papers", "mcp__paper__recommend_papers_for_paper", "mcp__paper__recommend_papers_from_examples", "mcp__paper__get_openalex_work", "mcp__paper__get_openalex_citations", "mcp__paper__get_openalex_references", "mcp__paper__search_openalex_authors", "mcp__paper__search_openalex_institutions", "mcp__paper__search_openalex_works", "mcp__paper__get_openalex_trends", "mcp__paper__list_openalex_topics" ], "deny": [] } } ```
