paper_search
智能学术论文检索系统，支持多维度相关性评分、学术质量评估、语义搜索等高级功能，专为研究员和教授设计
LABSCO SUMMARY
Country and open-access filters are what you cannot get from a plain literature search.
Filtering by the country of the authors' institutions turns "find papers about X" into "compare what China and the US published on X in 2024", and the open-access flag tells you upfront whether you can actually read the result. An email address is the whole entry cost — OpenAlex charges nothing.
What it is
A search front-end for the OpenAlex catalogue. One call takes a query plus filters and returns papers with their metadata: authors, venue, DOI, citation count, institutional affiliations, subject classification, and the abstract reconstructed from OpenAlex's inverted index.
What you get
- Keyword search across title, abstract and full-text content —
paper_search - Results narrowed by
country_code(institution country),year, andopen_access - Ordering by
cited_by_count,publication_dateorrelevance_score, up to 50 results per call - Per paper: title, authors, year, document type, abstract, journal or venue, DOI and URLs, citation count, author affiliations, and topic/subfield/field/domain classification
- Open-access status including article processing charge information
Requirements
Node.js version 18 or higher, and a valid email address in OPENALEX_EMAIL — OpenAlex asks for one for rate limiting and contact. No API key; OpenAlex is free. Run the built build/index.js over stdio, or put Supergateway in front of it to serve SSE on a port.
Setup effort
Build from source — git clone https://github.com/guangxiangdebizi/Paper-MCP.git
USE CASES
01
Building a reading list for a literature review
Search the topic sorted by cited_by_count and pull the top 20 in one call — each result already carries the abstract, so you can triage without opening anything.
02
Comparing research output between countries
Run the same query twice with different country_code values and a fixed year, then compare volume and citations across the two sets.
03
Finding papers you can actually read today
Set open_access to true so every result is freely available, and check the APC information that comes back if you are considering publishing there yourself.
