description: >-
Multi-source literature search, citation verification, MeSH search strategy,
citation file management (.nbib/.ris/.bib conversion), and reference management
(BibTeX, related articles, ID conversion) via MCP tools (PubMed, CrossRef, arXiv).
Use when the user needs coordinated multi-step literature workflows beyond a
single MCP call.
Academic Search
Multi-source literature search, citation verification, citation format conversion,
and reference management via MCP tools.
MCP Tools
Core Search
| 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
| 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 |
pubmed_convert_ids | DOI ↔ PMID ↔ PMCID conversion |
pubmed_lookup_mesh | MeSH term exploration and hierarchy |
pubmed_lookup_citation | Bibliographic citation → PMID lookup |
Source Routing
See Source Tiers & Reliability for the complete reliability classification and fallback routing rules. The T1→T2→T3 fallback chain is the standard execution order across all workflows.
Quick guide:
| User need | Primary (T1) | Secondary (T2) | Last Resort (T3) |
|---|---|---|---|
| Medical / clinical | PubMed | Semantic Scholar | Google Scholar |
| Cross-disciplinary | CrossRef | Semantic Scholar | Scopus |
| Preprints / CS / physics | arXiv | bioRxiv / medRxiv | — |
| Exhaustive review | PubMed + CrossRef + arXiv | Semantic Scholar + bioRxiv/medRxiv | WoS / Scopus |
| Citation count sensitive | Semantic Scholar | CrossRef | — |
| Chinese literature | — | — | CNKI / 万方 (manual) |

Environment Setup
API Keys (optional but recommended)
| Service | Env Var | Register At | Free Tier |
|---|---|---|---|
| Semantic Scholar | SEMANTIC_SCHOLAR_API_KEY | api.semanticscholar.org | 100 req/s with key (1/s without) |

Set via export or .env file.
Proxy (if behind firewall)

python scripts/preflight.pyRun before batch operations to verify API endpoints are reachable.
Format Converter Dependencies
The format converter (scripts/format-converter.py) uses Python stdlib only — no extra dependencies. Run python scripts/format-converter.py --test to verify the conversion pipeline.
Error Handling
- MCP tool unavailable: report specific failure, continue with remaining tools.
- No results: broaden terms, try alternative sources, suggest user refine query.
- Script failure (2x): fall back to manual generation from MCP-fetched metadata.
Limitations
- Google Scholar and Semantic Scholar are scraped (not API-backed) — results may vary.
- Chinese literature (C
