download_paper
Download a paper PDF (returns download information)
LABSCO SUMMARY
Strong on what was published recently, weak on history — and the README says so.
The archive has no public search endpoint, so search here filters the RSS feed, roughly the last 100 papers. That makes it good for tracking what is appearing now and poor for digging up an older paper you half remember. Fetching a known paper by its 2025/123 id works regardless of age.
What it is
A reader for the IACR Cryptology ePrint Archive, the preprint server for cryptography research. It works off the archive's RSS feed rather than a search API, which shapes what it can and cannot find.
What you get
- Papers searched by title, abstract, author or keyword, with an author filter and a date range —
search_papers - One paper's full details by its archive id, in the
2025/123form —get_paper - The latest published papers straight off the feed —
get_recent_papers - Web page and PDF URLs for a paper, and download information for its PDF —
get_paper_url,download_paper
Requirements
Node.js 18.0.0 or higher. No account, no key, no cookies. Runs as a Node process against the built dist/index.js. Two optional variables: DEBUG set to 1 for verbose logging, and MAX_RESULTS to cap search results, which defaults to 100.
Setup effort
One command — npx -y github:heewon-chung/eprint-mcp-server
USE CASES
01
Keeping up with what is being posted in cryptography
Pull the most recent papers off the feed and skim titles and abstracts, rather than checking the archive page yourself.
02
Reading a paper somebody cited by id
Fetch it by its archive id to get the full record, then get the web and PDF URLs to open or save it.
03
Watching an author's recent output
Search with the author filter and a date range. Expect coverage of recent postings — historical search is limited by the feed this server reads.
