nature-academic-search

nature-academic-search is a skill for Claude Code from YuanyuanMa03/academic-research-skills. It costs 74 tokens per session (1,464 once invoked), scanned A, original, MIT.

A literature-search and reference-management skill that searches Crossref, PubMed, and arXiv, services that index scholarly papers and preprints. It can also fetch papers, look up medical subject terms, verify citations, and convert citation formats.

In plain words
What is it for?
Use it to search for papers, retrieve a paper by DOI, PMID, or arXiv ID, create citations such as BibTeX or APA, explore MeSH medical terms, and manage citation files.
Why use it?
It brings several research tasks into one workflow instead of requiring separate searches and manual reference formatting. It supports different sources for biomedical, multidisciplinary, and physics, mathematics, computer science, or biology research.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

nature-academic-search scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 13d ago.

The scan reads SKILL.md. This mod also ships 22 executable files (install.sh, mcp-server/academic_search_server.py, mcp-server/sources/__init__.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 139 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Multi-source literature search, citation verification, citation format conversion, and reference management via MCP tools.

MCP Tools

Bundled MCP Server (academic-search)

The bundled MCP server provides these tools — use these names when calling the server:

Tool Purpose
search_papers Multi-source search across CrossRef, PubMed, arXiv (concurrent)
get_paper_by_id Fetch paper by DOI, PMID, or arXiv ID
get_citation Formatted citation output (APA, MLA, BibTeX, etc.)
lookup_mesh MeSH term exploration and hierarchy

External MCP Tools (require separate installation)

The following tools are referenced in workflows but require external MCP servers to be installed separately. If unavailable, fall back to the bundled search_papers tool.

Tool Source Best For
pubmed_search_articles PubMed MCP Biomedical, MeSH, clinical trials
search_crossref paper-search MCP Cross-disciplinary, citation counts
search_arxiv paper-search MCP Preprints (physics, math, CS, biology)

Extended Search (external only)

Tool Source Best For
search_google_scholar paper-search MCP Broad academic search (scraped)
search_semantic_scholar paper-search MCP Citation graph, field-of-study filters
search_biorxiv paper-search MCP Biology preprints
search_medrxiv paper-search MCP Medical preprints
search_webofscience paper-search MCP Curated index, citation reports
search_scopus paper-search MCP Broad scholarly database

PubMed Utilities

Tool Purpose
pubmed_fetch_articles Full metadata by PMID
pubmed_find_related Related article discovery
pubmed_format_citations APA / MLA / BibTeX / RIS formatting

What ships with it

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
