Scite

Search scientific literature and read full-text content from peer-reviewed papers. Use `dois` (preferred) or `titles` with targeted `term` queries to extract full-text passages from specific papers. Each call returns up to 5 relevant excerpts (~500 chars each) — vary search terms across calls to read through a paper section by section. **IMPORTANT — keep `limit` small.** Use `limit: 10-50` with `offset` for pagination. Large limits with full citations and excerpts produce very large payloads that consume significant LLM context. **Calling with no parameters browses the corpus** (210M+ papers, relevance-sorted). This is allowed for broad exploration but rarely what you want — pass `term`, `dois`, `titles`, or other filters for targeted results. **What This Tool Returns:** - Paper metadata: title, authors (first 3), abstract, DOI, journal, year, volume, issue, page - `fulltextExcerpts`: up to 5 passages (~500 chars) from the paper matching your query (OA only) - `access`: resolved access link with source, type (open/institutional/purchase), content type, and pricing - `citations`: Smart Citation statements — actual quoted text from citing papers, classified as supporting/contrasting/mentioning/unclassified (unclassified = statement present but classifier hasn't assigned a type) - `tally`: citation metrics (total, supporting, contrasting, mentioning, citing publications) - `retraction_notices`: editorial notices including retractions, corrections, concerns - `isOa`, `oaStatus`, `license`: open access information **Fetching Paper Metadata (no search term needed):** Pass `dois` or `titles` WITHOUT a `term` to retrieve metadata for specific papers. Example: `dois: ["10.1038/s41586-020-2012-7"]` **Full-Text Excerpts:** For OA papers, `fulltextExcerpts` contains passages matching your query. If empty, the full text is not indexed or terms didn't match — use the `access` field for the best link to the PDF or full text. **Smart Citations ARE Full-Text Evidence:** - `snippet`: exact sentence/paragraph from the citing paper's full text - `type`: classification (supporting, contrasting, mentioning, unclassified) - `section`: paper section (Introduction, Methods, Results, Discussion) - `sourceDoi`: paper containing this snippet; `targetDoi`: paper being cited **Search Capabilities:** - Boolean operators: AND, OR, NOT - Phrase search: "exact phrase" - Proximity: "term1 term2"~5 - Field filters: title, abstract, author, journal, year, affiliation - Citation filters: supporting_from/to, contrasting_from/to, mentioning_from/to - Editorial filters: has_retraction, has_concern, has_correction, has_erratum **Parameters:** - `term`: cross-field search query (optional when `dois`/`titles` provided) - `dois`: array of DOIs to filter to specific papers - `titles`: array of titles to filter (use when DOIs unavailable) - `limit`: max results (default: 10, max: 1000) - `offset`: pagination offset - Plus 20+ filter parameters (see schema) **Response Format:** ```json { "hits": [{ "doi": "10.1234/example", "title": "Paper Title", "authors": [{"authorName": "Jane Smith"}], "abstract": "Full abstract text...", "year": 2023, "journal": "Nature", "tally": {"supporting": 32, "contrasting": 8, "mentioning": 5}, "fulltextExcerpts": ["Relevant passage..."], "access": {"url": "https://...", "accessType": "open", "contentType": "pdf"}, "citations": [{"snippet": "These findings...", "type": "supporting", "section": "Results"}], "retraction_notices": [] }] } ```

Search patent families from the scite patents database. Use this tool to find patents related to scientific research topics. Returns patent families with titles, abstracts, inventors, assignees, filing status, and citation counts. **Parameters:** - q: Search query string (keywords, inventor name, assignee, etc.) - f: Space-delimited filters in key:value format (e.g. "assignee:Pfizer filing_status:granted") - p: Page number (default: 1) - s: Sort field (default: _relevance). Options: - _relevance: relevance score (sortDir ignored) - forwardCitationCount: number of forward citations - familySize: number of patents in the family - patents.publications.pubRef.date: publication date - patents.appRef.filingDate: application filing date - sortDir: Sort direction, asc or desc (default: desc). Ignored when s is _relevance. **Returns:** Patent families with metadata including title, abstract, inventors, assignees, classifications, and publication references.

Search clinical trials from the scite clinical trials database (ClinicalTrials.gov). Use this tool to find clinical trials related to diseases, interventions, sponsors, or research topics. Returns trials with titles, brief descriptions, sponsors, facilities, conditions, interventions, phase, and dates. Highlighted `<strong>...</strong>` snippets indicate which fields matched the query. **Parameters:** - q: Search query string (keywords, condition, intervention, sponsor, NCT id, etc.) - f: Space-delimited filters in `field:"value"` format (e.g. `conditions:"Cancer" trialState.phase:"Phase III"`) - p: Page number (default: 1) - s: Sort field (default: _relevance). Options: - _relevance: relevance score (sortDir ignored) - dates.startDate: trial start date - dates.completedDate: trial completed date - dates.lastUpdatedDate: last update date - sortDir: Sort direction, asc or desc (default: desc). Ignored when s is _relevance. **Returns:** Clinical trials with nctId, title, briefDescription, phase, sponsors, facilities, conditions, interventions, tags, startDate, completedDate, and publicationCount.

Fetch full details for a single clinical trial by NCT id. Use this after `search_clinical_trials` when you need the complete record for a specific trial, including the full `description`, study `design`, `enrollment`, `outcomes` (primary/secondary), full `eligibility` inclusion/exclusion criteria, `reportedEvents` (adverse events when the trial has posted results), principal investigator (`pi`), `contacts`, `citations` (related publications), and `resultsUrl`. The search tool returns a slim summary to save tokens; call this tool for a specific NCT id when you need those verbose fields for deeper analysis or patient-trial matching. **Parameters:** - id: NCT identifier (e.g. `NCT02986230`). **Returns:** A compact detail record preserving all trial fields except the low-signal `ontology` classifications.

Search research grants from the scite grants database (NIH RePORTER, NSF, SBIR/STTR, Wellcome, EU, and more). Use this tool to find grants by research topic, PI, organization, agency, or funding keywords. Returns grants with title, a short abstract preview, agency, organization, PI, country, dates, awardAmount, tags, and externalLink. Highlighted `<strong>...</strong>` fragments indicate which fields matched the query. **Grouping.** Resolute groups related grants under one shared slug (e.g. NIH subprojects of one center grant, or renewals of the same award). Each search result returns **only one representative grant** per group. `grantsInGroup` tells you how many total grants exist in the group; `siblingGrantIds` (when present) lists the other grant ids in the group. To pull the full record for a specific sibling, call `get_grant` with its id — do not re-search. **Abstract in search is a ~300-char highlighted preview, not the full text.** Call `get_grant` when you need the full abstract (often 1-3 KB) or source-specific identifiers (`awardYear`, `agencyTrackingNumber`, `contract`, `nihProgramCode`, `nihrApplicationId`). If the search result already contains the fields you need, do not call `get_grant`. **Parameters:** - q: Search query string (keywords, PI name, organization, agency, etc.) - f: Space-delimited filters in `field:"value"` format (e.g. `agency:"NIH" country:"United States"`) - p: Page number (default: 1) - s: Sort field (default: _relevance). Options: - _relevance: relevance score (sortDir ignored) - awardStartDate: grant start date - awardCloseDate: grant close date - awardNoticeDate: grant notice date - awardAmount: total award amount - employeeCount: PI employee count - sortDir: Sort direction, asc or desc (default: desc). Ignored when s is _relevance. **Returns:** Grants with id, title, abstract snippet, agency, organization, piName, country, award dates, awardAmount, tags, groupSlug, and grantsInGroup.

Fetch full details for a single grant by id. Call this after `search_grants` only when you need something the search result does not already have. Specifically, this returns: - Full `abstract` (search returns only a ~300-char highlighted preview; the full text is typically 1-3 KB). - Source-specific identifiers that search does not include: `awardYear`, `agencyTrackingNumber`, `contract`, `nihProgramCode`, `nihrApplicationId`. All other fields (title, agency, organization, piName, country, dates, awardAmount, tags, externalLink, etc.) are already present in search results — don't call `get_grant` just to get those. Also use this to pull siblings listed in `siblingGrantIds` on a search result: call `get_grant` once per sibling id you need. **Parameters:** - id: Grant identifier returned by `search_grants` (e.g. `5201339`, `nsf.0646294`, `wellcome.214402.Z.18.Z`). **Returns:** A compact detail record with the full abstract and the source-specific identifiers listed above; drops the low-signal `categories` ontology.

Search FDA 510(k) premarket notification clearances from the scite device database. Use this tool to find medical device clearances by device name, product code, applicant, clearance type, or K number. Returns clearances with device details, decision info, applicant information, and regulatory classifications. 510(k) is the FDA's premarket notification process -- manufacturers must demonstrate that their device is substantially equivalent to a legally marketed device before it can be sold. **Parameters:** - q: Search query string (device name, product code, applicant, K number, etc.) - f: Space-delimited filters in `field:"value"` format (e.g. `device.deviceClass:"2" decision.decisionCode:"SESE"`) - p: Page number (default: 1) - s: Sort field (default: _relevance). Options: - _relevance: relevance score (sortDir ignored) - device.device_class: device risk classification - device.date_received: date FDA received the submission - decision.decision_date: date of FDA decision - sortDir: Sort direction, asc or desc (default: desc). Ignored when s is _relevance. **Returns:** Device 510(k) clearances with kNumber, title, summaryText, device info (name, class, productCode, clearanceType, regulationNumber), decision info (code, description, date, committee), applicant details, and tags. **Note:** This tool returns structured clearance metadata only. For the actual narrative content of 510(k) summary documents (test results, substantial equivalence reasoning, indications for use, performance data), use `search_510k_summaries` instead.

Fetch full details for a single FDA 510(k) clearance by K number. Use this after `search_device510k` when you need the complete record for a specific clearance, including the full `summaryText` (the complete 510(k) summary statement, often very long), full `applicant` details (address, contact, country), `registration` info (FEI and registration numbers), and the complete `decision` object (code, description, committee, review flags). The search tool returns a brief highlighted snippet of the summary text; call this tool for a specific K number when you need the full text or detailed applicant/registration information. **Parameters:** - id: K number identifier (e.g. `K210674`). **Returns:** A compact detail record with full summary text, complete applicant information, registration details, and decision metadata.

Search the full text of FDA 510(k) summary PDF documents. This dataset contains OCR'd full-text content from FDA 510(k) premarket notification summary PDFs. Unlike `search_device510k` which returns structured clearance metadata (device class, applicant, decision codes), this tool searches the actual narrative text of 510(k) submissions and returns matching page-level snippets. Use this tool when the question involves the *content* of a 510(k) submission rather than its metadata. Common triggers: test results, performance data, biocompatibility, substantial equivalence comparisons, indications for use, predicate device comparisons, sterilization methods, software descriptions, bench testing, or clinical study summaries. When you already have a K number from `search_device510k`, use `get_510k_summary` to read the full document instead of searching again. **Parameters:** - q: Search query (technical terms, device descriptions, test methods, etc.) - f: Space-delimited filters in `field:"value"` format - p: Page number (default: 1) **Returns:** Documents with id, filename, tags, and page-level content snippets showing where the query matched within each 510(k) summary PDF.

Fetch the full text of a single FDA 510(k) summary PDF by document ID. Use this after `search_510k_summaries` or `search_device510k` when you need the complete narrative text of a 510(k) summary, not just search snippets or structured metadata. Returns the full extracted text organized by page. **Parameters:** - id: Document identifier (the K number, e.g. `K192757`). Can be obtained from either `search_510k_summaries` or `search_device510k` results. **Returns:** The full-text content of the 510(k) summary PDF, organized by page, with file metadata and ontology tags.

Search MHRA (Medicines and Healthcare products Regulatory Agency) safety alerts and publications. This dataset contains full-text content from MHRA drug safety alerts, medical device alerts, field safety notices, and regulatory publications.

The search tool returns a slim view; this tool adds detail-only fields. **Parameters:** - id: Drug record ID (the UUID from search_drugs results, e.g. `4dd865ec-8889-49ac-8c8f-4438875937ac`). **Returns:** A detailed drug record with the application's products and the main label sections (indications and usage, dosage and administration, contraindications, boxed warning, warnings and cautions, adverse reactions, drug interactions, use in specific populations, pharmacology, clinical studies, how supplied, overdosage, description).

Create a new Collection owned by the signed-in user. Use this to start a Collection from a list of DOIs the user wants to group, track, and analyze together. The caller becomes the Collection ADMIN. The returned `slug` identifies the Collection for `get_collection`, `update_collection`, `add_dois_to_collection`, and the other Collection tools. **DOI validation.** Provided DOIs are validated and resolved against scite; unknown DOIs are dropped and surfaced via the `unmatchedDoiCount` in the response. An empty `dois` list creates an empty Collection the user can add to later. **Scope.** This tool creates DOI-list Collections. Collections backed by a saved search query are created in the scite web app, not via MCP. **Parameters:** - name: Collection name (required). - description: Optional free-text description. - dois: Optional list of DOI strings to seed the Collection. - is_public: If true, anyone with the slug can view the Collection (default: false). **Returns:** The created Collection with id, slug, name, description, isPublic, doiQueryType, accessType, and DOI counts.

Fetch a single Collection (a saved, named set of papers) by its slug. Use the `slug` returned by `create_collection` or `search_collections`. Returns the Collection's identity, sharing, access level, and DOI counts. The caller must have at least VIEWER access (own it, be shared on it, or it is public). **Parameters:** - slug: The Collection slug (required). **Returns:** The Collection with id, slug, name, description, isPublic, accessType, and DOI counts.

List the Collections the signed-in user can access, with an optional name filter. Returns Collections the user owns, is shared on, or that are shared with their organization. Pass `q` to filter by a case-insensitive substring of the Collection name. This is a filter over the caller's own Collections, not a full-text search of all Collections. **Parameters:** - q: Optional case-insensitive name substring to filter by. **Returns:** `{collections: [...], total: N}` where each Collection has id, slug, name, accessType, and DOI counts.

Update a DOI-list Collection the signed-in user can edit. Partial update: only the fields you supply change; omitted fields keep their current values. Omitting `dois` leaves the DOI list untouched; supplying `dois` replaces it (unknown DOIs are dropped and surfaced via `unmatchedDoiCount`). Requires EDITOR or ADMIN access. Only DOI-list Collections can be updated here — saved-search Collections are managed in the scite web app. **Parameters:** - slug: The Collection slug (required). - name: New name (optional). - description: New description (optional). - dois: Replacement DOI list (optional; omit to leave DOIs unchanged). - is_public: New public flag (optional). **Returns:** The updated Collection with id, slug, name, accessType, and DOI counts.

Permanently delete a Collection. Requires ADMIN access on the Collection. This cannot be undone. The Collection and its DOI membership are removed. Only the Collection ADMIN may delete it. **Parameters:** - slug: The Collection slug (required). **Returns:** `{deleted: true, slug: "..."}` on success.

Add DOIs to a Collection. Works on both DOI-list and saved-search Collections. Requires EDITOR or ADMIN access. For a DOI-list Collection the DOIs are added to the list. For a saved-search Collection they are force-included (added to the manual include list) so they appear even if the search would not return them. DOIs already present are ignored. Use `create_collection` to make a new Collection or `remove_dois_from_collection` to take DOIs out. **Parameters:** - slug: The Collection slug (required). - dois: List of DOI strings to add (required, non-empty). **Returns:** The updated Collection with id, slug, name, and DOI counts.

Remove DOIs from a Collection. Works on both DOI-list and saved-search Collections. Requires EDITOR or ADMIN access. For a DOI-list Collection the DOIs are dropped from the list. For a saved-search Collection they are excluded (added to the exclude list) so they no longer appear even if the search would return them. DOIs not present are ignored. This removes papers from the Collection; it does not delete the Collection itself (use `delete_collection` for that). **Parameters:** - slug: The Collection slug (required). - dois: List of DOI strings to remove (required, non-empty). **Returns:** The updated Collection with id, slug, name, and DOI counts.
