PubMed MCP Server
Community MCP server for searching PubMed — the world's primary biomedical literature database from NCBI. Enables AI agents to search PubMed with keyword and journal filters, use MeSH (Medical Subject Headings) terminology, sort results smartly, and access biomedical research literature for healthcare, clinical, and research applications.

⚙ Agent Friendliness
🔒 Security
Public biomedical literature. Optional API key. HTTPS. Research tool — clinical context requires physician oversight.
⚡ Reliability
Best When
A medical research, clinical, or pharmaceutical agent needs to search PubMed for biomedical literature — using keyword, MeSH, and journal filters to find relevant studies, systematic reviews, and clinical research.
Avoid When
You need full text article content (PubMed provides metadata and abstracts; full text requires publisher access). For physics/CS/ML literature, use arXiv MCP instead.
Use Cases
- • Searching biomedical literature for clinical research and evidence-based medicine agents
- • Finding relevant medical studies and systematic reviews from healthcare AI agents
- • Using MeSH terms for precise medical topic searches from research assistant agents
- • Literature review automation for biomedical research and drug discovery agents
Not For
- • Non-biomedical literature (use arXiv MCP for physics/CS/math)
- • Full text article retrieval (PubMed provides abstracts; full text via publishers)
- • Clinical decision making without physician oversight
Interface
Authentication
NCBI API key optional but recommended for higher rate limits (10 req/sec with key vs 3 req/sec without). Free to obtain from NCBI.
Pricing
PubMed API (NCBI Entrez) is free government data. NCBI API key is free to register. MCP server is free open source.
Agent Metadata
Known Gotchas
- ⚠ Register a free NCBI API key — raises rate limit from 3 to 10 req/sec, essential for research workflows
- ⚠ PubMed has 35M+ articles — use MeSH terms and filters for precision; broad queries return too many results
- ⚠ Abstract-only access — full article text requires publisher API or institutional access beyond this MCP
- ⚠ Community server (lineex) — verify MeSH term handling and filter accuracy against NCBI documentation
